Description:FIELD OF THE INVENTION
[001] The present invention relates to a vehicle. More particularly, the present invention relates to a side stand cable operably connected to a throttle tube in the vehicle.
BACKGROUND OF THE INVENTION
[002] As per mandatory safety standards, a vehicle should not propel in a side stand ON position. Existing designs use a position detecting switch mounted on a side stand of the vehicle, which will detect a position of the side stand and allow or prevent starting of an ignition system based on the detected position of the side stand. The position detecting switch is mounted to the side stand using one or more fasteners. However, it has been seen that position detection by the position detecting switches may be highly inconsistent owing to variations in manufacturing and/or assembling, which in turn, affects safety of a rider as well as the vehicle. Also, cost of the position detecting switch is high. Also, as the position detecting switch is mounted on the side-stand which is close to the ground, there is a chance that position detection switch is damaged due to water entry, dust entry or objects on the road capable of hitting the position detection switch while riding the vehicle, which will lead to an overall increase in the cost owing to frequent replacement as well as maintenance of the position detection switch mounted on the side stand.
[003] In view of the foregoing, there is a need-felt to overcome at least the above-mentioned disadvantages of the prior art.
SUMMARY OF THE INVENTION
[004] In one aspect of the present invention, a vehicle having a side stand cable is disclosed. The vehicle comprises a handlebar tube, a throttle tube, a side stand, a throttle cable and the side stand cable. The throttle tube is operably connected to the handlebar tube and adapted to be rotatable from an idle position to a fully open throttle position in a clockwise direction. The throttle cable comprises a first end and a second end. The first end of the throttle cable is operably connected to the throttle tube. The second end of the throttle cable is operably connected to a throttle device. The throttle device regulates an amount of air-fuel mixture delivered to the power generating unit of the vehicle.
[005] The side stand cable comprises a first end and a second end. The first end of the side stand cable is operably connected to the throttle tube and the second end of the side stand cable is operably connected to the side stand of the vehicle such that movement of the throttle tube from the idle position to the fully open throttle position is prevented when the side stand is in ON condition and movement of the throttle tube from the idle position to the fully open throttle position is allowed when the side stand is in OFF condition.
[006] It is to be understood that movement of throttle tube allows the movement of the throttle cable, which is operably connected to a throttle valve of the throttle device. In an event where the movement of the throttle tube is restricted or prevented, the movement of throttle cable is also restricted or prevented. When the movement of the throttle cable is restricted, the throttle valve of the throttle device will not be operated and the required quantity of air-fuel mixture to propel the vehicle will not be supplied to the power generating unit of the vehicle. In other words, when the movement of throttle tube is prevented, no air-fuel mixture is supplied to the power generating unit and the vehicle will not propel or move.
[007] In an event where the movement of the throttle tube is allowed, the movement of throttle cable is also allowed. When the movement of the throttle cable is allowed, the throttle valve of the throttle device will be operated in proportion to the movement of the throttle cable and the required quantity of air-fuel mixture to propel the vehicle will be supplied to the power generating unit of the vehicle. In other words, in case the movement of throttle tube is allowed, air-fuel mixture is supplied to the power generating unit in proportion to the movement of the throttle tube/throttle cable, and the vehicle will propel or move.
[008] In an embodiment, the throttle tube comprises a first wall member, a second wall member and a third wall member. Each of the first wall member, the second wall member and the third wall member extends radially outwardly from an outer surface of the throttle tube. The first wall member, the second wall member and the third wall member are arranged successively adjacent to each other in a vehicle width-direction. The first wall member, the second wall member and the third wall member may be covered by a cover. The cover has one or more openings for receiving the throttle cable and the side stand cable. Each of the first wall member, the second wall member and the third wall member comprises a first cut-out portion and each of the second wall member and the third wall member comprises a second cut-out portion. The second cut-out portions are spaced from the first cut-out portions at a pre-defined distance in the clockwise direction of rotation of the throttle tube. The first end of the throttle cable is removably fitted in the first cut-out portions and a first portion of the throttle cable is arranged in a space between the first wall member and the second wall member. The first end of the side stand cable is removably fitted in the second cut-out portions and a first portion of the side stand cable is arranged in a space between the second wall member and the third wall member. The second end of the side stand cable is operably connected to a lock plate provided on the side stand. The second portion of the side stand cable is guided or routed through a stopper plate operably connected to a connector footrest mounted on the footrest of the vehicle.
[009] In a side stand OFF condition, a length of the side stand cable between the second cut-out portions and the lock plate is greater than a routing distance between the second cut-out portions and the lock plate such that a length of the side stand cable in excess of the routing distance allows rotation of the throttle tube from the idle position to the fully open throttle position in the clockwise direction. As already stated, movement of the throttle tube in the clockwise direction moves the throttle cable in the clockwise direction. Based on the movement of the throttle cable, the throttle valve of the throttle device is opened and air-fuel mixture is supplied to the power generating unit of the vehicle.
[010] In a side stand ON condition, a length of the side stand cable between the second cut-out portions and the lock plate is equal to a routing distance between the second cut-out portions and the lock plate such that no excess length of the side stand cable is available for rotation of the throttle tube from the idle position to the fully open throttle position in the clockwise direction and the movement of the throttle tube is restricted. The restriction of the movement of the throttle tube in the clockwise direction restricts the movement of the throttle cable in the clockwise direction. As the movement of the throttle cable is prevented, the throttle valve of the throttle device is not opened and no air-fuel mixture is supplied to the internal combustion engine.

DETAILED DESCRIPTION OF THE INVENTION
[012] Various features and embodiments of the present invention here will be discernible from the following further description thereof, set out hereunder. It is to be understood that a longitudinal axis refers to a front to rear axis relative to a two-wheeled vehicle, defining a vehicle longitudinal direction while a lateral/transverse axis refers to a side to side, or left to right axis relative to the two-wheeled vehicle, defining a vehicle lateral/width direction. Arrows provided in the top right or left corner of figures depicts direction with respect to the two-wheeled vehicle, wherein an arrow F denotes front direction, an arrow R indicates rearward direction, an arrow UP denotes upward direction, an arrow DW denotes downward direction, an arrow Rt denotes right direction, an arrow Lt denotes left direction, as and where applicable. Also, it is to be understood that the phraseology and terminology used herein is only for the purpose of description and should not be regarded as limiting.
[013] Figure 1 is a schematic view of a two-wheeled vehicle 10, in accordance with an embodiment of the present invention.
[014] The two-wheeled vehicle 10 includes a frame structure 11 (shown in Figure 2) to support different parts of the vehicle 10. A head tube 12 is provided at a front end of said frame structure 11. The head tube 12 supports a steering shaft (not shown) rotatably in a certain range. In an upper portion of the head tube 12, a handlebar tube 20 is rotatably connected to the steering shaft. The handlebar tube 20 is used to steer the vehicle 10 and is connected to a front wheel 21 through a front fork assembly 23. The front fork assembly 23, in turn, is connected to the handlebar tube 20 by means of a pair of upper and lower brackets (not shown). The front fork assembly 23 is further supported partially on a front fender 22 and is connected to the front wheel 21. An upper portion of the front wheel 21 is covered by the front fender 22 which prevents mud and water from getting deflected towards an upper portion of the front fork assembly 23.
[015] In a front portion of the frame structure 11 (shown in Figure 2) a fuel tank 24 is arranged immediately behind the handlebar tube 20 and is disposed over a main tube 13 of said frame structure 11 (shown in Figure 2) and above a power generating unit 25. A seat 30 is placed behind the fuel tank 24. The seat 30 includes a front rider portion and rear pillion portion. In an embodiment, the front rider portion and the rear pillion portion are provided as separate seat portions. In an embodiment, the front rider portion and the rear pillion portion are provided as a single seat portion.
[016] For safety of a rider and in conformance with the traffic rules, a headlamp unit 31 and a turn signal lamp unit 32 are provided in a front portion of the vehicle 10. The headlamp unit 31 and the turn signal lamp unit 32 are housed in a headlamp housing assembly 33.
[017] The safety of said two-wheeled vehicle 10 is also improved by providing a braking system, for example a linked type braking system which controls braking operation of a front brake device 41 and a rear brake device 42 of the front wheel 21 and a rear wheel 35 respectively. The braking system may also include a pressure control unit 43 and aids in ensuring that there is appropriate distribution of braking force upon actuation of at least one of a front brake actuating means (not shown) or a rear brake actuating means (not shown) between the front brake device 41 and the rear brake device 42, and thereby protects the vehicle 10 from the risk of being toppled or from the risk of skidding.
[018] Further, suspension systems are provided for comfortable steering of said vehicle 10 on road. The front fork assembly 23, which forms the front suspension system, serves as a rigid component just like the frame structure 11. The front fork assembly 23 clamped to the head tube 12 through an upper bracket (not shown) and a lower bracket (not shown) is capable of being moved in the left and right direction of the vehicle 10. Further, a rear suspension system 37, which may be a hydraulic damped arrangement, is connected to the frame structure 11 at a rear portion thereof. Particularly, at the rear portion of the frame structure 11, the rear wheel 35 is suspended by the rear suspension system 37.
[019] The power generating unit 25 is mounted to a front lower portion of the frame structure 11 (Shown in Figure 2) by means of a front power generating unit mounting bracket (not shown) and disposed below a portion of the main tube 13. The power generating unit 25 is equipped with an exhaust system that includes an exhaust pipe (not shown) connected to the power generating unit 25 and a muffler (not shown) connected to the exhaust pipe. The muffler (not shown) extends rearwards along the rear wheel 35.
[020] Power from the power generating unit 25 is transmitted to the rear wheel 35 through the transmission assembly 26, so as to drive and rotate the rear wheel 35. The transmission assembly 26 includes a gearbox containing gear train and a drive mechanism connecting the gearbox to the rear wheel 35. Particularly, the gear train includes a gear shift shaft, and a plurality of gears, each having a varying gear ratio. Particularly, speed change is achieved by operation of a gear shift linkage assembly which is operatively connected to the gear shift shaft (not shown) of the transmission assembly 26. Thus, power from the power generating unit 25 is transmitted to the rear wheel 35 rotatably supported at a rear end of a swing arm 47. A rear fender 48 for covering an upper side of the rear wheel 35 is mounted to the rear portion of the frame structure 11 to prevent mud and water splashed by the rotating rear wheel 35 from entering the muffler, the power generating unit 25 and other parts disposed close to the rear wheel 35.
[021] Figure 2 is a perspective view of a frame structure 11, in accordance with an embodiment of the present invention.
[022] As shown, the frame structure 11 comprises the handlebar tube 20 extending between a first end 20a and a second end 20b. For the purposes of the present invention, when the rider is sitting on the vehicle 10, the first end 20a of the handlebar tube 20 is on right hand side of the rider and the second end 20b of the handlebar tube 20 is on left hand side of the rider. The first end 20a of the handlebar tube 20 is adapted to receive a throttle tube 50. The throttle tube 50 comprises a first portion 50a and a second portion 50b. The throttle tube 50 is adapted to receive a throttle cable 52 and a side stand cable 54. The first portion 50a of the throttle tube 50 is partially or fully covered with a cover 56. The cover 56 has one or more holes for receiving the throttle cable 52 and the side stand cable 54.
[023] The second portion 50b of the throttle tube 50 is covered with a grip member 58 to be held by the rider of the vehicle. The throttle tube 50 is adapted to be rotatable from a neutral position (closed or idle throttle position) (IP) (Refer Figure 10) to a fully open throttle position (FP) (Refer Figure 10) in a clockwise direction and from the fully open throttle position (FP) to the neutral position (IP) in an anti-clockwise direction.
[024] The throttle cable 52 has a first end 52a (Refer Figure 10) and a second end (not shown). The first end 52a of the throttle cable 52 is operably connected to the throttle tube 50 and the second end of the throttle cable 52 is operably connected to a throttle device 60. When the throttle tube 50 is rotated in the clockwise direction CW (Refer Figure 10), the throttle cable 52 in the throttle tube 50 is pulled to open a throttle valve (not shown) in the throttle device 60. The degree of rotation of the throttle tube 50 in the clockwise direction determines degree of opening of the throttle valve (not shown) in the throttle device 60 and therefore, the acceleration of the vehicle 10 can be controlled by the rider by controlling the throttle tube 50 of the vehicle 10. Similarly, the degree of rotation of the throttle tube 50 in the anti-clockwise or counter clockwise direction will determine closing of the throttle valve and therefore, the deacceleration of the vehicle 10. The construction, interrelation and working of the throttle tube 50, throttle cable 52, throttle device 60 and throttle valve are well known in the prior art and not discussed in the detail here.
[025] The side stand cable 54 also has a first end 54a (Refer Figure 4) and a second end 54b (Refer Figure 4). The first end 54a of the side stand cable 54 is operably connected to the throttle tube 50 and the second end 54b of the side stand cable 54 is operably connected to a side stand 62 of the vehicle 10. The side stand 62 of the vehicle 10 is generally provided on the left hand side of the vehicle 10. The side stand 62 is pivotally connected to the frame structure 11 for supporting the vehicle 10 on a ground during parking. The side stand 62 is attached to the frame structure 11 by means of a side stand mounting bracket 64. The side stand 62 further comprises a lock plate 62a (Refer Figure 8) provided with an opening slot 62b (Refer Figure 11) and a mounting nut 62c (Refer Figure 11). The lock plate 62a is provided in a region proximate to the frame structure 11 in side stand ON condition. The side stand ON condition is a condition when the vehicle 10 is parked using the side stand 62. Similarly, the side stand OFF condition is a condition when the vehicle 10 is not parked using the side stand 62. The frame structure 11 further comprises a rider footrest 66 on the left hand side of the vehicle 10. A connector footrest 68 is mounted on a rider footrest 66 and a stopper plate 70 is attached to a flange portion of the connector footrest 68. The stopper plate 70 is also provided with an opening slot 70a (Refer Figure 11). The second end 54b of the side stand cable 54 is routed through the opening slot 70a of the stopper plate 70 and assembled in the opening slot 62b of the lock plate 62a.
[026] Figure 3 is a perspective view of the throttle cable 52 and the side cable 54 operably connected to the vehicle 10, in accordance with an embodiment of the present invention.
[027] The first end 52a (Refer Figure 10) of the throttle cable 52 is operably connected to the throttle tube 50 and the second end of the throttle cable 52 is operably connected to the throttle device 60. Also, the first end 54a (Refer Figure 4) of the side stand cable 54 is operably connected to the throttle tube 50 and the second end 54b of the side stand cable 54 is connected to the side stand 62.
[028] Figure 4 is a perspective view of the side stand cable 54, in accordance with an embodiment of the present invention.
[029] As shown, the side stand cable 54 comprise an outer cable 72 and an inner cable 74. The outer cable 72 is a hollow tubular pipe comprising a first end 72a, a second end 72b and an internal passage extending between the first end 72a and the second end 72b. The inner cable 74 is disposed inside the internal passage of the outer cable 72 and extends between the first end 54a and the second end 54b. The length of the inner cable 74 is greater than a length of the outer cable 72 and a first portion 74a of the inner cable 74 extends from the first end 72a of the outer cable 72 and a second portion 74b of the inner cable 74 extends from the second end 72b of the outer cable 72. Each of the first end 54a and the second end 54b of the inner cable 74 has an integrally formed or removably attached billet 76. Each of the first end 72a and the second end 72b of the outer cable 72 has a head portion 78 and a nut 80. It is to be understood that the first end 54a of the inner cable 74 is operably connected to the throttle tube 50 of the vehicle 10 and the second end 54b of the inner cable 74 is operably connected to the side stand 62 of the vehicle 10.
[030] Figure 5 is an exploded view of the throttle tube 50, in accordance with an embodiment of the present invention.
[031] As shown, the throttle tube 50 comprises the first portion 50a and the second portion 50b. The first portion 50a of the throttle tube 50 is adapted to be fitted onto the handlebar tube 20. In one non-limiting example, an inner diameter of the first portion 50a of the throttle tube 50 is greater than an outer diameter of the handlebar tube 20 such that the throttle tube 50 is fixedly or removably attached to the handlebar tube 20. The second portion 50b of the throttle tube 50 is adapted to receive a throttle grip 82. The throttle grip 82 may be removably or fixedly received on the second portion 50b of the throttle tube 50. The throttle grip 82 is used to maintain throttle control by the rider of the vehicle 10. The first portion 50a of the throttle tube 50 is covered with the cover 56. In one non-limiting example, the cover is made in two parts. In one non-limiting example, as shown in Figure 5, the cover is divided into an upper half 56a and a lower half 56b. In another non-limiting example, the cover 56 is divided into a front half and a back half. It is to be understood that when the cover 56 is made in two parts, both the parts 56a, 56b are removably attached together with one or more fasteners F1 such as screws, bolts, nuts and the likes.
[032] The cover 56 comprises one or more cut-out portion or holes (not shown) to receive the throttle cable 52 and the side stand cable 54. In one non-limiting example, the cover 56 comprises a cut-out portion covered with a removable plate like structure 84. The removable plate like structure 84 comprises a first hole 84a for receiving the throttle cable 52 and a second hole 84b for receiving the side stand cable 54. The plate like structure 84 is removably attached to the cover 56 with one or more fasteners F2.
[033] Figure 6 is a perspective view of the throttle tube 50, in accordance with an embodiment of the present invention. Figure 7a and Figure 7b are plan views of the throttle tube 50, in accordance with an embodiment of the present invention.
[034] The first portion 50a of the throttle tube 50 comprises a first wall member 86, a second wall member 88 and a third wall member 90 extending radially outwardly from an outer surface 50c of the throttle tube 50. In one non-limiting example, the first wall member 86, the second wall member 88 and the third wall member 90 extends from a segment of the outer surface 50c of the throttle tube 50. The first wall member 86, the second wall member 88 and the third wall member 90 are arranged successively adjacent to each other in a vehicle width-direction. Each of the first wall member 86, the second wall member 88 and the third wall member 90 comprises a first cut-out portion 92. Each of the second wall member 88 and the third wall member 90 comprises a second cut-out portion 94. The second cut-out portions 94 are spaced from the first cut-out portions 92 at a pre-defined distance in the clockwise direction CW of rotation of the throttle tube 50.
[035] The first end of 52a the throttle cable 52 is removably fitted in the first cut-out portions 92. In one non-limiting example, the first end 52a of the throttle cable 52 comprises a billet adapted to be removably fitted into the first cut out portions 92. A first portion 52c of the throttle cable 52 is arranged in a space between the first wall member 86 and the second wall member 88. The first end 54a of the side stand cable 54 is removably fitted in the second cut-out portions 94 and a first portion 74a of the side stand cable 54 is arranged in a space between the second wall member 88 and the third wall member 90. In one non-limiting example, as shown in Figure 4, the first end 54a of the side stand cable 54 comprises the billet 76 adapted to be removably fitted into the second cut-out portions 94.
[036] Figure 8 is a perspective view of the side stand 54 in side stand ON condition, in accordance with an embodiment of the present invention. Figure 9 is a perspective view of the side stand 54 in a side stand OFF condition, in accordance with an embodiment of the present invention.
[037] As shown, the side stand 62 is pivotally connected to the frame structure 11 for supporting the vehicle 10 on the ground during parking. The side stand 62 is attached to the frame structure 11 by means of a side stand mounting bracket 64. The side stand 62 further comprises a lock plate 62a provided with an opening slot 62b and a mounting nut 62c. The lock plate 62a is provided in a region proximate to the frame structure 11 in side stand ON condition. The side stand ON condition is a condition when the vehicle 10 is parked using the side stand 62. Similarly, the side stand OFF condition is a condition when the vehicle 10 is not parked using the side stand 62. The frame structure 11 further comprises a rider footrest 66 on the left hand side of the vehicle 10. A connector footrest 68 is mounted on a rider footrest 66 and a stopper plate 70 is attached to a flange portion of the connector footrest 68. The stopper plate 70 is also provided with an opening slot (not shown). The second end 54b of the side stand cable 54 is routed through the opening slot (not shown) of the stopper plate 70 and assembled in the opening slot 62b of the lock plate 62a.
[038] In the side stand ON condition as shown in Figure 8, it can be seen that a length (L) of the side stand cable in excess of the routing distance between the second cut out portions and the lock plate is utilized for parking the vehicle and is not available for rotation of the throttle tube in the clockwise direction (also shown in Figure 10a). However, when the side stand is in side stand OFF condition as shown in Figure 9, the length of cable in excess of the routing distance is not utilized for parking the vehicle and is available for rotation of the throttle tube in the clockwise direction (also shown in Figure 10b).
[039] Figure 10a is a sectional view of the throttle tube 50 in a side stand ON condition, in accordance with an embodiment of the present invention. Figure 10b is a sectional view of the throttle tube 50 in a side stand OFF conditions, in accordance with an embodiment of the present invention.
[040] Figure 10a, in conjunction with Figure 8, illustrates the working of the present invention in the side stand ON condition. In the side stand ON condition, a length of the side stand cable 54 between the second cut-out portions 94 and the lock plate 62a is equal to a routing distance of the side cable 54 between the second cut-out portions 94 and the lock plate 62a such that no excess length (L) of the side stand cable 54 is available for rotation of the throttle tube 50 from the neutral position (IP) to the fully open throttle position (FP) in the clockwise direction CW. In other words, the excess length (L) of the side stand cable 54 is utilized in parking the vehicle 10 and is not available for rotation of the throttle tube 50 in the clockwise direction CW . As a result, the rotation of the throttle tube 50 and the throttle cable 52 from the neutral position IP to the fully open throttle position FP is prevented or restricted in the side stand ON condition. When the movement of the throttle cable 52 is restricted, the throttle valve of the throttle device 60 will not be operated and the required quantity of air-fuel mixture to propel the vehicle 10 will not be supplied to the power generating unit 25 of the vehicle 10. In other words, when the movement of throttle tube 50 is prevented, no air-fuel mixture is supplied to the power generating unit 25 and the vehicle 10 will not propel or move.
[041] Figure 10b, in conjunction with Figure 9, illustrates the working of the present invention in the side stand OFF condition. In the side stand OFF condition, the length of the side stand cable 54 between the second cut-out portions 94 and the lock plate 62a is greater than the routing distance of the side stand cable 54 between the second cut-out portions 94 and the lock plate 62a such that excess length L of the side stand cable is available for rotation of the throttle tube 50 from the neutral position IP to the fully open throttle position FP in the clockwise direction. In other words, the excess length L of the side stand cable is not utilized in parking the vehicle 10 and is available for rotation of the throttle tube 50 in the clockwise direction CW. As a result, the rotation of the throttle tube 50 and the throttle cable 52 from the neutral position IP to the fully open throttle position FP is allowed in the side stand OFF condition. When the movement of the throttle cable 52 is allowed, the throttle valve of the throttle device 60 will be operated, in proportion to the movement of the throttle tube 50 /throttle cable 52 in the clockwise direction and the required quantity of air-fuel mixture to propel the vehicle 10 will be supplied to the power generating unit 25 of the vehicle 10. In other words, when the rotation of throttle tube 50/ throttle cable 52 is allowed, air-fuel mixture is supplied to the power generating unit 25 and the vehicle will propel or move.
[042] Figure 11 is a perspective view of the side stand cable 54 operably connected to the side stand 62, in accordance with an embodiment of the present invention.
[043] As shown, the second end 54b of the side stand cable 54 is routed or guided through the stopper plate 70 and locked by means of a fastener F3 in the lock plate 62a. The stopper plate 70 is provided with the opening slot 70a for receiving the second end 54b of the side stand cable 54. The lock plate 62a is also provided with the opening slot 62b for receiving the second end 54b of the side stand cable 54. The billet 76 provided on the second end 54b of the side stand cable 54 is locked in the lock plate 62a of the side stand 62.
[044] The claimed features of the present invention as discussed above are not routine, conventional, or well understood in the art, as the claimed features enable the following solutions to the existing problems in conventional technologies. Specifically, the technical problem of using position detection switches on the side stand 62 for detecting the position of the side stand 62 in the vehicle 10, which are high in cost, difficult to maintain and less accurate is solved by present invention.
[045] The present invention provides a simple and economical solution for preventing the movement of the vehicle in a side stand ON condition. The present invention uses a simple mechanical side stand cable 54 having the first end 54a operably connected to the throttle tube 50 and the second end 54b operably connected to the side stand 62. The rotation of the throttle tube 50 and, therefore, the throttle cable 52 is prevented by the side stand cable 54 in the side stand ON condition and allowed in the side stand OFF condition.
[046] The present invention reduces the overall cost of the vehicle 10 as the manufacturing cost, assembly cost as well as the maintenance costs associated with the side stand cable 54 are low.
[047] The side stand cable 54 in the present invention uses a mechanical cable and, therefore, no interaction with an electronic control unit of the vehicle 10 is required for functioning of the throttle device 60. In prior arts, position detection switch mounted on the side stand 54 is in communication with the electronic control unit of the vehicle 10.
[048] The side stand cable 54, which is a mechanical cable, is more durable than the position detection switches with respect to dust, water and obstacles such as stones, pebbles on the road.
[049] While the present invention has been described with respect to certain embodiments, it will be apparent to those skilled in the art that various changes and modification may be made without departing from the scope of the invention as defined in the following claims. , Claims:WE CLAIM:
1. A vehicle (10) comprising:
- a handlebar tube (20);
- a throttle tube (50) operably connected to the handlebar tube (20) and adapted to be rotatable from an idle position (IP) to a fully open throttle position (FT) in a clockwise direction (CW);
