TECHNICAL FIELD
[0001] The present subject matter relates generally to saddle-ride type vehicles incorporating an electric prime mover and more particularly to electrical connection to the electric prime mover.
BACKGROUND
[0002] Generally, commuting is an essential activity every day for majority of the people. Typically, there are various types of vehicles that are used for community depending on the application and the capacity thereof. Of these, a particular category of vehicles have acquired prominence due to their ease of operation and compact layout. Saddle ride-type vehicles are one such category of motor vehicles that are having at least two-wheels and provide a saddle-ride type posture when being operated. These vehicles are having a compact layout and are adapted to accommodate at least one user.
[0003] Generally, these vehicles include at least one prime mover that is either an electric motor or an internal combustion (IC) engine. Some vehicles incorporate both the electric motor and the internal combustion engine that are referred to as hybrid vehicles. Vehicles incorporating electric motor as one of the prime movers are gaining popularity because of their ease of operation, low cost of operation, and reduced emissions. Therefore, the vehicles incorporating the electric motor that are either purely electrical vehicles or the hybrid vehicles are having the prime mover that is either fixedly mounted to a frame member or is swingably connected to the structural member of the frame member. The electric motor is driven by a primary and/or auxiliary power source that provides electrical energy that is converted to mechanical energy by excitation of electrical coils provided in the electric motor. An electrical connection is provided between the electric motor and the auxiliary power source in a controlled mechanism. These electrical connections are high current carrying cables that are provided to be connected to the electric motors. So, these electrical connections are to be securely located in order to deliver reliable operation of the electrical and hybrid vehicles.

DETAILED DESCRIPTION [00013] Generally, the vehicles with the electric prime mover being mounted to the structural member, the frame member is either swingably or rigidly supports the structural member. The auxiliary power unit (battery) or the control unit is preferably mounted on to the frame member that is a rigid structure. The electrical connections are routed to the electric motor acting as an electric prime mover from the auxiliary power unit or the control unit. Therefore, the electrical cables are to be routed about the frame member and then to the electric motor. Generally, the electrical cables have to be routed till the stator of the electric motor that incorporates the windings. Typically, sheathed cables are used to

supply/receive power from the battery to the electric motor and to receive signals from the sensors mounted on the stator of the electric motor. Also, the electrical cables are routed through the shaft of the electric motor that is mounted to the structural member. This necessitates the electrical cable to undergo various bends and turns to be routed to the electric motor. However, the aforementioned requirement makes the electrical cables vulnerable to failures as the routing path may include rigid structures like brackets, or sharp welding disposed in the vicinity that could damage electrical cable during an undesired event. The undesired event may include during assembly or during a foreign object coming in contact with the electrical cable. Also, the cable is prone to damage from stone hitting due to bad road conditions or can get rubbed with elevated structures like footpath when vehicle comes near it. Such damage could cause the electrical cable to result in electrical short circuit that could damage the electric motor, the auxiliary power unit/source, or the control unit.
[00014] Moreover, in some vehicles with the electric motor being mounted
to the hub of the wheel and the structural member is swingably connected to the frame member or is pivotably connected to the frame member. Firstly, this requires the cable to be routed to a substantial distance to the rear/front of the vehicle as the shaft/axle that supports the wheel is disposed either in the front or in the rear of the vehicle making the electrical cable routing also to be long and to be vulnerable to failure. Also, use of swinging type structural member results in relative motion between the cable ihnt is passing by the singing structure and rigid/movable parts. Some structural member like fork suspensions undergoes reciprocating motion. This results in rubbing off of the electrical cable against the frame member and the structural member resulting in wear out of the insulating member of electrical cable.
[00015] Generally, in some vehicles the electrical cable is routed through a part disposed adjacent to the electric prime mover by providing a hole in the part to.route the cable through that additional part. However, this increases the bends through which the cable has to be routed and also increases number of contact member that are disposed in (he vicinity of the electrical cable, which eventually

leads to the above stated failures. Also, assembly and dis-assembly during maintenance and servicing become cumbersome as the cable is routed through multiple parts of the vehicle requiring removal of cable from more than one part. Additionally, in some vehicles the cable is routed inward of the structural member like swing arm that supports the axle thereby keeping the cable in proximity to the wheel which is a rotating member with large diameter. The swinging movement of the swing arm makes the cable vulnerable to come in contact with the wheel thereby resulting in rubbing off or breakage with the rotating wheel. Also, the presence of prime mover like electric motor and the internal combustion engine in proximity creates vibrations that could dislocate the cable from a desired position that could make the cable come in contact with moving/rotating parts. Also, the gap between the wheel and the swing arm is very less thereby mandating the cable assembly to be routed with sharp bends. This also requires the conducting metallic cables to be bent thereby compromising on the structural strength.
[00016] Moreover, in case of hybrid vehicles incorporating internal combustion engine along with the electric motor, a transmission system is also used which is also disposed inwardly of the swing arm. Therefore, the space between the outer side of wheel with the electric motor and inward of the swing arm is very cramped with marly moving parts that further make the cable vulnerable to failure. Rubbing of cable with any of the moving parts results in wear out of the insulating member/sheath resulting in exposure of the conducting cables that leads to electrical short circuit, electrical part failure, or in aggravated situations leading to fire. This could leave the user stranded with the vehicle thereby providing poor reliability. Further, water or mud may enter the shaft through the routing path entering the cable, which would affect the inner windings and teeth as rust or corrosion may occur and also might short the windings.
[00017] Also, during servicing or maintenance, the inspection or access to the cable is very complex as the cable is inward of the swing arm thereby complicating the process.

[00018] Hence, il is an objective of Ihe present subject matter that addresses the aforementioned and other problems in the prior art. As there is a need for a vehicle with an electric prime mover that is reliable to operate.
[00019] The present subject mailer provides a vehicle comprising an electric prime mover. It is a feature that the vehicle is preferably a saddle-ride type vehicle that includes at least two wheels. The electric prime mover is swingably connected to a frame member of the vehicle. The vehicle may include an 1C engine that operates as another prime mover and the user can operate any one of the prime movers or both the prime movers.
[00020] It is an aspect of the present subject matter that the structural member can be a swingarm or a crankcase that support at least one wheel of the vehicle. The electric prime mover is an electric motor that is brush less direct current (BLDC) type and the electric motor is functionally connected to a high capacity battery/battery pack(s) through a master control unit. Preferably, the electric prime mover is disposed below a seat assembly of the vehicle thereby providing a compact saddle ride-type vehicle layout.
[00021] It is a feature that the structural member may include one or more arms that extends substantially in a longitudinal direction of the vehicle. The electric prime mover is mounted to the one or more arms acting as axle support thereof, wherein in a structural member with two arms the electric motor is either mounted to the arms or between the arms. The electric prime mover is preferably hub mounted to a wheel and is disposed away from a pivot portion of the structural member. Therefore, it is an advantage that the vehicle utility space lhat includes the step-through space or the utility box space is retained.
[00022] Il is a feature that the electric prime mover includes a stationary member and a rotating member that are supported by a shaft that acts as axle for the electric prime mover and also the wheel. The shaft is disposed substantially in width direction of the vehicle and is supported by the structural member. The stationary member is fixedly mounted to the shaft and the rotating member is rotatable about the shaft. In one embodiment, the rotating member is connected to

a rim portion of the wheel. Therefore, the current electric prime mover provides the benefit of direct torque transfer.
[00023] The stationary member includes plurality of teeth provided with windings/coils. The rotating member rotates about the stationary member with an inner peripheral surface of the rotating member facing the teeth. The inner peripheral surface is provided with magnets affixed thereat. Further, a cable assembly functionally connected to the windings provides required current/voltage for operation thereof.
[00024] The cable assembly is routed through the shaft towards a front portion of the prime mover assembly. The shaft provides the path for securely routing the cable assembly from the inside to an outer portion of the prime electric mover. The cable assembly is routed outward from the shaft and then substantially .outwardly of the structural member. It is a feature that the cable assembly is enclosed by only one member, which is the shaft. This provides an advantage that the post machining or modification of other parts like brake drum for routing the cable assembly is eliminated.
[00025] It is an aspect of the present subject matter that the number of components through which the cable is routed is optimum thereby providing ease of assembly and also maintenance. Especially, the cable assembly being disposed outward of the swing arm in a width direction provides ease of access to the service personnel for inspection and maintenance.
[00026] It is a feature that in a vehicle with the IC engine acting as additional prime over, the cable assembly is securely disposed between an L-shaped space formed between an outer lateral side of the structural member and a lower side of the crankcase cover of the IC engine. This protects the cable assembly from any lateral impacts and also the cable assembly is substantially inward with respect to outer most portion of the crankcase cover. Thus, the cable assembly is securely routed toward front portion from the electric prime mover.

[00027] It is a feature that the cable assembly is preferably routed out from the shaft outward of the structural member and at a portion ahead of the securing assembly that supports at least one of mounting portions for the shaft, and a rear suspension. This keeps the cable assembly away from interfering with any of the surrounding parts of the securing assembly. Also, one or more guide members securely support the cable assembly and the guide members are selectively disposed along the path.
[00028] It is a feature that the cable assembly includes power cables and signal cables. The power cables are capable of providing power to the electric motor and the single cables provide status and operating parameters of the electric motor.'The power cables and the signal cables are individually insulated by an insulating material. Further, the power cables and the signal cables are wither combined insulated by a combined insulator member or by using separate insulator depending on application. Further, the elastic guard member securely annularly encloses the combined insulator member, wherein the elastic guard member is having a cylindrical cross-section that is capable of expanding and compressing with the length or positional variations due to swinging of structural member or swinging of electric prime mover.
[00029] It is a feature that the shaft supported by and secured to the structural member defines a cable path including a first passage, an axial path, and a second passage. The axial path extends substantially along an axis of the shaft and the first passage and the second passage are disposed at an acute angle with respect to the axial path, wherein the first passage and second passage provide a small inclined path thereof.
[00030] It is a feature that the second passage providing exit point outward of the structural member provides freedom of curvature for the cable to have a long curvature as there are no immediate members.
[00031] It is a feature that the first passage is disposed substantially in proximity to a shaft center of the shaft and the second passage is disposed away from the shaft center. The axial path, the first passage, and the second passage are

forming a continuous path for routing the cable assembly from the inward portion of the stationary member to outward of the shaft. In one implementation, the cable assembly takes only two bends, which are at the first passage and at the second passage thereby reducing number of vulnerable points of the cable assembly.
[00032] Jt is a feature that the second passage is connected to the axial path and is provided in a second orientation that is preferably between the forward orientation and the downward orientation thereby protecting the first passage from being vulnerable to entry of water or mud. Moreover, the second orientation provides the ease of routing of the cable assembly towards the front portion.
[00033] Jt is an additional feature that the cable assembly is disposed away from the rotating member especially away from the electric prime mover and the wheel, which is having a large diameter. At least one arm member of the structural member is disposed between the wheel and the cable assembly thereby completely isolating the cable assembly thereof.
[00034] It is an additional feature that the vehicle incorporating another prime mover like the internal combustion engine, the transmission system is disposed between wheel with the electric prime mover and the swing arm. The cable assembly is also securely disposed away from the transmission system which is also moving assembly. For example, the transmission system may include a chain drive and sprockets that are metallic members and the cable assembly is kept away from the metallic moving members.
[00035] It is another feature that the first passage is disposed in a second orientation that provides the freedom of routing the cable in any orientation for providing connection to the windings or the sensors.
[00036] It is another feature that the cable assembly is annularly enclosed by the elastic guard member disposed along at least a length of the path of the cable assembly. A clearance is provided between the outer peripheral portion of the cable assembly and the inner peripheral portion of the elastic guard member to

enable relative movement between them especially during swinging motion of the electric prime mover.
[00037] The elastic guide member is secured to the structural member that is acting as axle support for the hub mounted electric prime mover. A radial clearance is provided between the cable assembly and the elastic guide member wherein the elastic guard member is capable of structurally expanding and compressing for compensating any variations due to motion of structural member. The motion includes a swinging motion due to pivotal connection or reciprocating motion due to compression or expansion of suspension.
[00038] It is an additional feature that the elastic guide member is provided with at least one converging portion having a tapering diameter. The converging portion abuts the cable assembly thereby holding the cable assembly. It is a feature the elastic guard member is retained at desired position with respect to cable assembly. In one implementation, the covering portion at the converting side at least partially enters into the second passage whereby the converging portion securely guides the cable assembly into the shaft. It is an advantage that the cable assembly is protected at the bent portion.
[00039] It is an aspect that a bush member is mounted to the shaft on side from where the cables is routed out, wherein the bush member is provided with a U-shaped cut that abuts against the cable assembly thereby holding the cable assembly in a desired orientation. Therefore, the cable assembly routed out from the shaft outward of the structural member is provided with a smooth curvature and the bush member mounted to the shaft at the end portion from which the cable is routed out enables in retaining the orientation of the cable assembly with the desired curvature.
[00040] It is a feature that the cable assembly extending in the forward direction from the shaft extends substantially adjacent to the structural member and then extends upwards with a first inclination at an acute angle. The first inclination does not require sharp bend of the cable assembly at the same time keeps the cable assembly substantially away from/above a pivot portion of the

main stand of the vehicle. The main stand includes a lever which in a disengaged condition of the main stand extends upwards beyond the structural member. It is yet an additional feature that the cable assembly is disposed inward of the lever arm and upward of the main stand thereby retaining the cable assembly away from this moving part.

[00054] Fig, 2 (b) depicts an isometric view of the stationary member, in accordance with the embodiment of Fig. 2 (a). Also, Fig. 2 (b) depicts cross-sectional view of a printed circuit board mounted to the stationary member taken along axis B-B'. The stationary member 305 accommodates plurality of sensing components 320. The plurality of sensing components 320 includes one or more positional sensor(s) 320, like the Hall sensors, soldered with plated through-hole technique to a printed circuit board (PCB) 330, which is placed on stationary member 305. The signal cable 335 is secured through one or more loops. In the depicted implementation, a first loop LI is provided for the signal cable 335 and subsequently a second loop L2 is provided. The loops LI, L2 are formed by proving a ring like structure on the stationary member 305 about which the signal cable 335 is wound at least once. This securely holds the signal cable 335 against any pull and against vibrations. Further, the signal cable 335 is provided with a third loop L3 that forms a U-shape behind the PCB 330 as shown in enlarged view of the PCB 330. In assembled condition, the signal cables 335 will be touching the teeth 345 of the stationary member 305 at the third loop L3. The signal cable 335 taken through a first hole FH provided on the PCB 330 will have a close clearance with the first hole FH. Therefore, the two loops LI, L2 provided on the armature of the stationary member 305 and the third loop formed on the PCB 330 and soldering of the sensing components 320 to the PCB 330 will protect the sensing components 320 from failure due to direct pull or vibrations.

[00056] Fig. 2 (c) depicts a cross-sectional view of the prime mover assembly taken along axis A-A', in accordance with the embodiment as depicted in Fig. 2

(a). The Fig. 2 (c) depicts only ihe second prime mover 120. The shaft 135 is substantially having a cylindrical cross-section along at least an axial length thereof.

Preferably, the first passage 3I6A and the second passage 3I6C are disposed at an angle 9 with respect to the axial path 316B/axis S-S' of the shaft 315, wherein the axial path 316B extends substantially along the axis S-S' of the shaft 315. The cable path 316 being provided substantially within the shaft 315 eliminates additional routing portion. Further, the shaft 315 provided with the hollow portion formed by the cable path 316 improves the structural strength thereof.
[00057] Further, the first passage 316A is disposed substantially in proximity to the axial center of the shaft SC, which is referred to as shaft center SC, and the second passage 3I6C is disposed away from the shaft center SC. The axial path 3I6B, the first passage 3I6A, and the second passage 3I6C are forming a continuous path for routing the cable assembly 325 from the inward portion of the stationary member 305 outward of the shaft 315. In the depicted implementation, the first passage 3I6A is extending in a first direction that is rearward. The second passage 3I6C is extending in a second direction that is in forward direction. This forms the cable assembly 325 being disposed in an S-shaped profile, wherein, the first passage 3I6A and the second passage 316C are deposed at an angle 6 preferably in the range of 10-45 degrees providing smooth radius of curvature and minimizes assembly stress on the cable assembly 325 as well as enabling ease of assembly. The transition from the axial path 3I6B

towards either of the first passage 3I6A or the second passage 316B is provided with a curved transition to reduce wear out.

Also, the Fig. 2 (d) depicts a perspective view of the shaft 314. The shaft 314 in the present embodiment is provided with the first passage 3I6A and the second passage 3I6C substantially in the same orientation. The cable assembly is routed in a U-shaped orientation. Further, the cable assembly 325 is routed outward from the second passage 3I6C towards the outward lateral side of the cable assembly 325. The second passage 316C is disposed on the shaft to ensure that the opening thereof for guiding the cable assembly 325 is substantially outside the bearing structure 135. This provides an advantage that the cable assembly 325 is routed outward from the shaft without interfering with the structural member 135. This reduces the number of turns and bends. Further, the cable assembly 325 annularly enclosed by the elastic guard member 340 also extend along the path of the cable assembly 325. In the present implementation, the elastic guard member is a spring that is made of a non-ferrous rigid material. A clearance is provided between the outer peripheral portion of the cable assembly 325 and the inner peripheral portion of the elastic guard member 340. Further, at end portions of the elastic guide member 340 is provided with at least one converging portion 340A that is having a tapering diameter. Further, the converging portion 340A abuts the cable assembly 325 and at least partially enters into the second passage 3I6C whereby the converging portion 340A rigidly holds the cable assembly 325. This protects the cable assembly 325 at the bend portions as the elastic guard member 340 is capable of adapting to the profile thereof. Further, the converging portion 340A is stretched and routed inside the exit path 316C, and is retained in place using hard sealant to restrict wire movement. This also has the benefit of maximizing the curvature or bend of the cable assembly 325 towards the converging portion 340A as compared to when the cable assembly 325 is routed through inside of the structural member 135. Additionally routing of the cable

assembly 325 inside ihe structural member 135 lends to enlarge the width of the vehicle and complicates packaging.
[00059] Further, a bush member 355 is mounted to the shaft 314, wherein the bush member 355 is provided with a U-shaped cut that abuts against the cable assembly 325 thereby holding the cable assembly 325 closer to the structural member 135 and maintaining bend radius of the cable assembly and providing constant gap between the structural member 135 and the cable assembly 325, post assembly.
[00060] Fig. 2 (e) depicts a sectional view of the shaft taken along axis B-B\ in accordance with the embodiment as depicted in Fig. 2 (d). The cable path 316 includes an entry passage 316A disposed substantially in proximity to a shaft center SC of the shaft 315 and the entry passage 3I6A is disposable in any orientation to enable connection with the winding(s) that are disposed annularly about the stator. The exit passage 316C is disposed at a region Eli defined between a front portion F and bottom portion Dw of the shaft 315, wherein the cable assembly 325 is guided outward from the shaft 315 at the region ER. The region ER provides optimum exit path for the cable assembly 325 from the shaft 315 thereafter the cable assembly 325 is securely extending along at least a portion of the structural member 135.
[00061] Fig. 2 (f) depicts a side view of the prime mover assembly 200, in accordance with the embodiment of Fig. 2 (a). The cable assembly 325 extends outward from the shaft 315 through a second passage 3I6C that is disposed cither in forward direction or downward direction or a circumference formed between the forward direction and the downward direction. The elastic guard member 340 extends along the path of the cable assembly 325. The cable assembly 325 extending in the forward direction from the shaft 315 extends adjacent to the structural member 135 and then the cable assembly 325 extends upward with a first inclination or a first curvature making an acute angle a that is in the range of 15-45 degrees. The first inclination is above a pivot portion PP of the main stand 220 of the vehicle 100. Also, the first inclination provides optimum routing

length for the cable assembly 325 as the cable assembly 325 is diagonally routed avoiding sharp bends. Additionally, the first inclination keeps the cable assembly 325 away from the pivot point nf the structural member 135 and also enables routing of the cable upwards ahead of the crankcase cover 210. The main stand 220 includes a lever 220L which in a disengaged condition of the main stand 220. extends upwards beyond the structural member 135. The cable assembly 325 is disposed inward of the lever arm 220L and upward of the main stand 220. Then the cable assembly 325 extends upwards adjacent to at least one of a cylinder head 235 or cylinder block 240 toward an upward portion of the prime mover assembly 200 and the cable assembly 325 thereat is supported by a guide member 350 disposed on a cooling cowl assembly.
[00062] The internal combustion engine 115 is functionally coupled to the electric prime mover 120 through a driven sprocket 360. The driven sprocket 360 is sandwiched between the structural member 135 and the electric prime mover 120 as the driven sprocket 360 is also concentrically deposed about the shaft 315 and the electric prime mover 120. Either a chain drive is used to connect a drive sprocket (not shown) of the engine assembly 115 to the driven sprocket 360. In other embodiment, a belt drive with suitable drive and driven member are functionally connected to the engine assembly 115 and the rear wheel respectively. The cable assembly 325 is disposed away from the driven sprocket 360, which is a rotating member. Preferably the cable assembly 325 extending along said structural member 135 is routed substantially away from the moving members like the driven sprocket 360, the chain/belt drive, and the wheel 125 thereby securing the cable assembly 325 from getting damaged.
[00063] The elastic guard member 340 enables movement of the cable assembly 325 therein even when there is relative length variation of the cable assembly 325 due to swinging motion of the structural member 135. The elastic guard member 340 which is preferably a spring enables forward-rearward movement of the cable assembly 325 therein. This accommodates any cable movement. Further, the cable assembly 325 is preferably provided with circular

cross-section and the elastic guard member 340 that is also having a circular cross-section with some clearance between them. Also, the elastic guard member 340 is capable of providing smooth curvature at the bends.
[00064] In one embodiment, a detachable cover (not shown) is provided that is capable of covering at least a portion of the cable assembly 325, the structural member 135, and at least a portion of the electric prime mover 120 for additionally protecting the prime mover assembly 200 at defined portion.
[00065] Fig. 3 depicts a side view of a prime mover assembly 201 for a typical electric vehicle, in accordance with another embodiment of the present subject matter. The prime mover assembly 201 includes only an electric prime mover 120 that is rolatably supported by the structural member 135.

The cable path 316 includes an exit passage 3I6C guiding the cable assembly 425 out of the shaft 315 outwardly of the structural member and adjacent to an outer face FO of the structural member 135.
[00066] The structural member 135 supports an auxiliary storage unit 116 that is fixedly mounted. The auxiliary storage unit 116 is capable of accommodating one or more auxiliary storage unit(s) (not shown). Further, the auxiliary storage unit 116 is capable of accommodating a master control unit (not shown) therein. The cable assembly 425 extends in the forward direction from the shaft 315 and is disposed adjacent to at least a length of the structural member 135. The structural member includes one or more cross-members 136 disposed at an elevation from the arm members of the structural member 135 for securely supporting the auxiliary storage unit 116 thereat. Then the cable assembly 425 extends upward with a first inclination or a first curvature making an acute angle with a horizontal line/plane. The first inclination is above a pivot portion PP of the main stand 220 of the vehicle 100. The main stand 220 includes a lever 220L which in a disengaged condition of the main stand 220 extends upward and is substantially laterally away from the structural member 135.
