BACKGROUND
[0002] In the last few decades, two-wheeler automobile industry has shown a remarkable growth and development, in terms of technology as well as sales. Due to consistent advancement in technology, two-wheeled vehicles, such as bicycles, motorcycles, scooters and light-weight scooters, have succeeded in maintaining their popularity among different sections of society. Different sections of society, based on their requirement, utilize the two-wheeled vehicles for various purposes, such as a recreational activity, a means of transportation, and for sports activities. As a result, it becomes pertinent for the two-wheeler automobile industry to constantly develop and modify the components of the two-wheeled vehicles to suit requirements of different riders.
[0003] In accordance with the same ideology, various types of braking systems have been developed for facilitating braking functionalities in the two-wheeled vehicles.

DETAILED DESCRIPTION
[00012] The subject matter described herein relates to a synchronized braking system for a two-wheeled vehicle, according to an embodiment of the present subject matter.
[00013] Conventionally, two-wheeled vehicles are provided with a braking system for slowing or stopping the vehicle. The braking system, usually, includes at least one brake assembly, such as a front wheel brake assembly and a rear wheel brake assembly for a front wheel and a rear wheel, respectively. Such brake assemblies may include, but are not limited to a cam lever, a hinge pin, and a pair of brake shoes. Further, each of the front wheel brake assembly and the rear wheel brake assembly is connected to a brake lever for actuation. For example, the brake lever may be coupled to a pair of brake shoes for applying friction to each wheel of the two-wheeled vehicle, as and when required. The brake lever can be connected to the brake assembly in a variety of ways. For example, the brake lever can be connected to the brake assembly by means of a cable. In such a case, one end of the cable may be secured to the brake assembly, and the other end of the cable may be secured to the brake lever. Consequently, actuation of the brake lever may result in actuation of the brake assembly and subsequently, the brake may be applied.
[00014] Generally, the front wheel and the rear wheel are provided with separate braking systems. Conventional two-wheeler braking systems usually include either hand-operated brakes for both the wheels or include a combination of hand-operated and foot-operated brakes. In the latter case, generally, the front wheel brakes are hand-operated, and include a front wheel brake lever mounted on a handle of the two-wheeled vehicle for actuation, whereas the rear wheel brakes can be foot-operated by a rear wheel brake pedal provided near a foot-rest of the rider.
[00015] During operation of the brakes, usually, riders apply the rear wheel brake alone. Such a practice stems from the fact that actuating both the brake levers at the same time may be inconvenient for the rider. In addition, when the front wheel brake is applied, less weight on the front wheel and weight transfer towards the front wheel cause the front wheel to brake abruptly, and may result in a sudden jerk to the vehicle. The sudden jerk may affect the ride quality and may disturb the balance and stability of the vehicle leading to an accident. However, on the other hand, the braking force applied for braking the rear wheel may have to be limited, to prevent skidding of the vehicle. As a result, the deceleration experienced by the vehicle may also be limited and subsequently, the stopping distance of the vehicle may be significantly large.
[00016] Conventionally, in order to address the above-mentioned concerns, braking systems that allow simultaneous actuation of a front brake and a rear brake by application of a single brake lever have been developed. Such braking system is capable of uniting the braking operation of both the front wheel brake and the rear wheel brake with the help of a single braking force transmitting member, for example a rear wheel braking force transmitting member. Accordingly, upon actuation of the single braking force transmitting member, such a braking system may allow application of braking force to the front wheel as well as the rear wheel of the vehicle. Therefore, the front wheel brake and the rear wheel brake can be simultaneously applied by actuating a single braking force transmitting member, for example, the rear wheel braking force transmitting member. In addition to being convenient for the rider, such braking systems may ensure that the deceleration of the vehicle can be increased and subsequently, the stopping distance may be reduced. Further, as would be understood, in two-wheeled vehicles with such braking systems, a front wheel brake lever may also be provided to independently operate the front wheel brake.
[00017] Further, in such conventional braking systems, a cable from each of the front wheel brake lever and the rear wheel braking force transmitting member may be connected to the front wheel brake assembly. In one example, a cable connects the rear wheel braking force transmitting member to the front wheel brake assembly. Similarly, another cable connects a front wheel brake lever to the front wheel brake assembly. Further, the front wheel brake assembly may include a cam lever and each hinge pin for supporting each of the cables. Therefore, the first cable and the second cable may be coupled to the front wheel brake assembly through the cam lever, and may maintain a contact with the corresponding hinge pin.
[00018] In the conventional braking systems, upon actuation of the combined braking force transmitting member, the braking force is distributed to the front wheel brake and the rear wheel brake. However, even in such scenarios, due to lesser weight on the front wheel brake than that on the rear wheel brake, the braking force experienced by the front wheel brake may be substantially more than the rear wheel brake causing instability of the vehicle. Such situations may also result the vehicle to nose dive, i.e., experience a jerk in the forward direction. Under such circumstances, the rider, for example a novice rider, may experience discomfort while riding. In addition, various components, such as front fork suspension assembly and the wheel, may experience severe loads forces leading to excess wear and tear, and increasing the cost of maintenance of the vehicle.
[00019] Further, during operation of such braking systems, when the rider actuates the combined braking force transmitting member, the first cable is pulled to actuate the cam lever of the front wheel brake assembly. However, in such a situation, the second cable may remain stationary with reference to the first cable and the cam lever. As a result, the portion of the cam lever may slide over the hinge pin in contact with the second cable.
[00020] In addition, the conventional braking systems employ a large number of components and linkages to connect the combined brake lever to both the rear wheel brake assembly and the front wheel brake assembly. Consequently, weight of such braking systems may be substantially high. Further, such heavy and complex braking systems with the large number of components may require greater maintenance, and skilled labor. Such a situation may add to the maintenance cost of the vehicle. In addition, due to lack of space on the vehicle, accommodating such a bulky arrangement poses a problem. Accordingly, the conventional braking systems may suffer from lack of overall braking effectiveness, increased weight, and high costs.
[00021] Conventionally, such braking systems are provided to improve braking efficiency while actuating rear braking force transmitting member alone over standard brake system that has independent control for both the brakes. Such prior art braking systems that involves simultaneous operation of front wheel brake and rear wheel brake includes an additional lever that is used to connect the rear wheel braking force transmitting member, for example, a rear wheel brake pedal to the brake actuating members, for example, brake cables or brake rods, are often referred to as an equalizer, balancing element, or pulley and like.
[00022] The equalizer of such conventional systems is generally pivoted on the brake pedal. Thus, the brake cable for actuating the front brake has to be routed in such a manner, to take a reverse direction towards the vehicle front. Such complex routing of the brake cable creates a curvature or bends in the cable, which increases the undesirable friction resulting in lesser braking efficiency. Moreover, in such prior art braking systems, the equalizer that is pivoted on the brake pedal occupies considerable amount of space in the brake pedal region of the vehicle. This influences the critical vehicle layout parameters like footrest position to change and hence requiring gross changes in the layout.
[00023] Though, such prior art brake systems address the issues relating to reliability, the equalizer that is added to adjust difference in free-play between front and rear brake systems by its pivotal action tends to increase the complexity of the braking system and often requires large space and increased number of parts. Moreover, safety becomes significant while using rear braking force transmitting member alone on slippery surfaces and in curves. These prior art systems provide certain amount of delay required for controlling front wheel brake while actuating the rear braking force transmitting member, on account of safety. Thus, causing safety related problems, more particularly, in slippery conditions, and in curves. Furthermore, in such prior art systems there is always a compromise between safety and ease of operation. Hence, the challenge in such prior art braking systems is to achieve trade-off between safety and ease of operation.
[00024] The synchronized braking system (SBS) of the present subject matter is provided to overcome the above stated problems of the conventional braking systems known in the prior art. For example, the synchronized braking system of the present subject matter provides a front wheel brake capable of applying braking forces to a front wheel of a two-wheeled vehicle, and a rear wheel brake capable of applying braking forces to a rear wheel of the two-wheeled vehicle. A front wheel brake actuating lever is mounted to a handlebar of the vehicle. The front wheel brake actuating lever is coupled to the front wheel brake by a front wheel brake cable. Further, a synchronous braking force transmitting member is pivotably supported to a frame structure of the vehicle at least by a pivot element. The synchronous braking force transmitting member includes a first end for receiving brake actuating forces, a second end pivotably connected to a rear wheel brake actuating member, and an intermediately extending arm coupled to a synchronous front wheel brake actuating member. A holding member is rotatably supported to the pivot element. The holding member movably supports the synchronous front wheel brake actuating member.
[00025] In one embodiment, the front wheel brake of synchronized braking system can be a drum brake, while the synchronous front wheel brake actuating member can be a synchronous front wheel brake cable. Similarly, in an embodiment, the rear wheel brake is a drum brake and the rear wheel brake actuating member is a rear wheel brake rod.
[00026] In one embodiment, the first end of the synchronous braking force transmitting member is a brake pedal, which is mounted to the frame of the vehicle for synchronously transmitting braking forces to both the rear wheel brake and the front wheel brake. Further, in an embodiment, the synchronous front wheel brake actuating member includes an outer brake cable and an inner brake cable.
[00027] In an embodiment, the extending arm is hingedly coupled to a rotatable link at one end of the rotatable link, while another end of the rotatable link is capable of hingedly receiving the inner brake cable of the synchronous front wheel brake actuating member.
[00028] Further, the holding member movably supports the outer brake cable of the synchronous front wheel brake actuating member. The holding member rotatably abuts against a first stopper that is secured to the frame structure when rotating in a direction towards a vehicle front side. Similarly, the holding member rotatably abuts against a second stopper that is secured to the frame structure when rotating in a direction away from a vehicle front side.
[00029] In one embodiment, the second stopper is coupled to the holding member by means of a return spring element.
[00030] Further, the synchronized braking system of the present subject matter ensures that the front brake cable is actuated downwards, thereby eliminating a plurality of drawbacks of the prior art braking systems. For example, any unnecessary increase in friction due to cable bending is eliminated. Further, the actuation of the front brake cable in reversed direction is also eliminated. Moreover, the synchronized braking system of the present subject matter enables achieving a pre-determined delay in synchronous actuation of the front wheel brake. Furthermore, the synchronized braking system of the present subject matter is compact and is capable of being incorporated in existing set-ups without involving any major change to the overall layout of the vehicle.
[00031] These and other advantages of the present subject matter would be described in greater detail in conjunction with the figures in the following description.
[00032] FIG. 1 illustrates a layout of a braking system of a two-wheeled vehicle, in accordance with an embodiment of the present subject matter. More particularly, the braking system 100 describes a synchronous braking system 100. The system 100 includes a front wheel brake 106 and a rear wheel brake 108. In an embodiment, the rear wheel brake 108 and the front wheel brake 106 of the present subject matter are capable of being synchronously actuated by means of a synchronous brake assembly 104. Further, a front wheel brake lever 110 of a front brake actuation assembly 102 may be independently actuated to apply the front wheel brake 106. Similarly, a rider may actuate a synchronous braking force transmitting member 112 of the synchronous brake assembly 104 for applying the front wheel brake 106 as well as the rear wheel brake 108. In one implementation, the front wheel brake lever 110 may be disposed on a right-hand side of a handle bar (not shown) of the vehicle, while the synchronous braking force transmitting member 112 may be disposed on a frame member (not shown) adjoining a rider’s foot rest (not shown). In a further implementation, instead of the independently provided front wheel brake lever 110, the braking system 100 may include a rear wheel brake pedal (not shown) to independently apply the rear wheel brake 108. Therefore, in such an implementation, the braking system 100 may include the rear wheel brake pedal to independently apply the rear wheel brake 108, and the front wheel brake lever 110 may act as the integrated brake actuating member for applying the front wheel brake 106 as well as the rear wheel brake 108.
[00033] Further, in an embodiment, a synchronous front wheel brake actuating member 116 and an independent front brake cable 114 may be connected to a front wheel brake assembly (not shown) of the front wheel brake 106. The front wheel brake assembly may include a cam lever (not shown), and an end (not shown) of each of the synchronous front wheel brake actuating member 116 and the independent front brake cable 114. In one implementation, a force suppressing apparatus (not shown) may also be provided to support synchronous front wheel brake actuating member 116 and the independent front brake cable 114 for improving safety.
[00034] FIG. 2 (a) illustrates a two-wheeled vehicle 200 depicting the braking system 100, in accordance with the embodiment depicted in Fig. 1 of the present subject matter. In an embodiment, the vehicle 200 includes a handle bar assembly 216 that is enclosed on both sides by a headlamp assembly 202. In an embodiment, the handlebar assembly 216 and the headlamp assembly 202 are supported by means of a head pipe 204, which extends downwardly from the handlebar assembly 216 towards a front wheel 212. In an embodiment, a main tube 208 of the vehicle 200 extends downwardly rearward from the handlebar assembly 216 head pipe 204 intersection towards a rear of the vehicle 200. An internal combustion engine 210 is disposed in a space formed between the main tube 208 and the head pipe 204. In an embodiment, the synchronous braking force transmitting member 112 is disposed in the vicinity of the engine 210 and is downwardly coupled to the vehicle frame structure to actuate a rear wheel brake (not shown) disposed on a rear wheel 214. In an embodiment, the main tube 208 of the vehicle 200 extends rearwardly to accommodate a seating structure 206 of the vehicle 200.
[00035] FIG. 2 (b) illustrates a frame structure of the two-wheeld vehicle 200 depicting the braking system 100, in accordance with an embodiment of the present subject matter. In an embodiment, the front wheel brake lever 110 is supported on the handlebar assembly 216. More particularly, the front wheel brake lever 110 is supported on the right hand side of the handlebar assembly 216. In an embodiment, the front wheel brake cable 114 (not shown) connects the front wheel brake lever 110 to the front wheel brake 106. The front wheel brake cable 114 enables independent actuation of the front wheel brake 106 when actuating the front wheel brake lever 110. In one embodiment, the synchronous front wheel brake actuating member 116 and a rear wheel brake actuating member 118 are functionally coupled to the synchronous braking force transmitting member 112 such that the actuation of the synchronous braking force transmitting member 112 causes a corresponding simultaneous actuation of the front wheel brake 106 and the rear wheel brake 108 in no particular order. In one embodiment, the synchronized front wheel brake actuating member 116 and the front wheel brake cable 114, the other end of which is coupled to the front brake lever 110, are connected to a cam lever (not shown) of the front wheel brake assembly 102. In an embodiment, when the front brake lever 110 is actuated, the front wheel brake 102 is independently controlled by means of the front brake cable 114. Similarly, the actuation of the synchronous braking force transmitting member 112 also causes actuation of the front wheel brake 106 independent of the front brake lever 110 actuation. Further, the actuation of the synchronous braking force transmitting member 112 also causes a corresponding actuation of the rear wheel brake 108. In an alternative embodiment, the synchronized front wheel brake actuating member 116 is coupled to the front wheel brake lever 110, such that the actuation of the synchronous braking force transmitting member 112 causes a corresponding actuation of the front wheel brake 106 through the front brake cable 114 that is connected to the front wheel brake lever 110. In another embodiment, the front wheel brake 106 is a disc brake capable of being hydraulically actuated by means of a master cylinder (not shown) in the vicinity of the front wheel brake lever 110. In such a construction, the synchronous braking force transmitting member 112 is connected to the master cylinder (not shown) for the purpose of actuating the front wheel brake 106. Similarly, in one embodiment, the rear wheel brake actuating member 118 is a rear brake rod 118, while in an alternative embodiment, the rear wheel brake actuating member 118 is a rear wheel brake cable. In one embodiment, the synchronized front wheel brake actuating member 116 is routed along the main tube 208 of the vehicle 200.
[00036] FIG. 3 (a) illustrates an exploded view of a synchronized braking assembly 104 of the braking system, in accordance with an embodiment of the present subject matter. In an embodiment, the synchronous braking force transmitting member 112 has a front end 302 that is capable of receiving braking forces applied by the rider. In an embodiment, the synchronous braking force transmitting member 112 is pivotally coupled to a frame structure 322 by means of a pivot element 324. In one embodiment, the front end 302 of the synchronous braking force transmitting member 112 is rotatably disposed downwardly forward towards a vehicle front side. Similarly, the rear brake pedal 112 also includes a second end 304 that is rotatably disposed upwardly rearward of the pivot element 324. In an embodiment, the rear brake rod 118 is pivotally coupled at a rear brake rod mounting end 314 wth the second end 304, such that the rotatable actuation of the first end 302 causes a corresponding actuation of the second end 304, which in turn actuates the rear brake rod 118. In an embodiment, an intermediate extending arm 306 is disposed adjoining the pivot element 324 to pivotally support the synchronized front wheel brake actuating member 116. In an embodiment, the synchronized front wheel brake actuating member 116 is coupled to the intermediate extending arm 306 by means of a rotatable link 318. In one embodiment, a holding member 316 is rotatably disposed about the pivot element 324 adjoining the synchronous braking force transmitting member 112. However, the holding member 316 is capable of rotating independently of the synchronous braking force transmitting member 112 about the pivot element 324. In an embodiment, the holding member 316 movably supports the synchronous front wheel brake actuating member 116.
[00037] Further, in one embodiment, the frame strucutre 322 is provided with a first stopper 328, which stops the rotation of the holding member 316 in a first direction, for example, when the holding member 316 rotates in a clockwise direction. Similarly, the frame structure 322 is provided with a second stopper 326 capable of stopping the rotation of the holding member 316 in a counter-clockwise direction. In an embodiment, the second stopper 326 is coupled to the holding member 316 by means of a return spring element 320. In an embodiment, the rider enables actuation of the synchronous braking force transmitting member 112 by resting against a rider footrest 310, which is supported about a frame support member 312 connected to the frame structure 322 of the vehicle 100. In an embodiment, a centre stand 308 is connected to the frame structure 322 downwardly disposed below the frame support member 312.
[00038] FIG. 3 (b) illustrates a side view of a non-operated condition of the synchronized braking assembly 104 of the braking system, in accordance with an embodiment of the present subject matter. In an embodiment, the synchronous braking force transmitting member 112 including the first end 302, the second end 304 and the intermediate extending arm 306 are rotatable about a pivot point 330. Further, in an embodiment, the rotatable link 318 is hingedly supported at a hinge point 336 of the intermediate extending arm 306, such that the rotation of the intermediate extending arm 306 causes a corresponding rotational movement of the rotatable link 318. The synchronized front wheel brake actuating member 116 includes is coupled to the rotatable link 318 at an inner cable hingedd joint 332, while an outer cable 334 of the synchronized front wheel brake actuating member 116 is supported by the holding member 316 (not shown).
[00039] FIG. 3 (c) illustrates a side view of a first operated condition of the synchronized braking assembly 104 of the braking system, in accordance with a preferred embodiment of the present subject matter. In an embodiment, during a first operated condition of the synchronized braking assembly 104, the braking forces are transmitted through the first end 302 of the synchronous braking force transmitting member 112 by the rider. This makes the synchronous braking force transmitting member 112 to rotate about the pivot point 330 to a first predetermined rotational distance. This causes the braking forces to be transmitted from the first end 302 to the second end 304 of the synchronous braking force transmitting member 112. The rotation of the second end 304 causes the rear brake rod 118 pivoted about a rear brake rod pivot point 338 on the second end 304 to be further actuated. The rotation of the synchronous braking force transmitting member 112 also transmits forces to the intermediate extending arm 306, which causes a corresponding rotational movement of the rotatable link 318 and the synchronized front wheel brake actuating member 116 linked to the rotatable link 318, which further rotates the holding member 316 to which the outer cable 334 of the synchronized front wheel brake actuating member 116 is supported. Moreover, the transmission of braking forces to the rear brake rod 118 causes the rear brake rod 118 to move linearly towards a vehicle front side. The other end of the rear brake rod 118 is connected to a rear brake cam lever (not shown) of the rear wheel brake 108 (not shown), which further causes one or more rear brake shoes (not shown) to actuate the rear wheel brake 108 by engaging with an inner surface of a rear wheel drum (not shown). The actuation of the rear wheel brake 108 limits the linear movement of the rear brake rod 118 after a predetermined distance.
[00040] FIG. 3 (d) illustrates a side view of a second operated condition of the synchronized braking assembly 104 of the braking system, in accordance with a preferred embodiment of the present subject matter. In an embodiment, during the second operated condition of the synchronous braking force transmitting member 112 occurs when braking forces are continued to be transmitted at the first end 302 of the synchronous braking force transmitting member 112 even after the actuation of the rear wheel brake 108 (not shown) and the corresponding limitation of the linear movement of the rear brake rod 118. The continued rotation of the intermediate extending arm 306 causes a corresponding movement of the rotatable link 318, which further causes the synchronized front wheel brake actuating member 116 to move along with the holding member 316. The rotation of the holding member 316 in a direction towards the vehicle front side is retarded by a first stopper 328 that is disposed on the frame structure 322 substantially adjoining the intermediate extending arm 306. The limitation of the rotation of the holding member 316 by the first stopper 328 limits the movement of the outer cable 334 of the synchronized front wheel brake actuating member 116. However, as an inner brake cable 340 of the synchronized front wheel brake actuating member 116 is hinged at the hinge point 336 on the intermediate extending arm 306 of the synchronous braking force transmitting member 112, the rotatable link 318 continues to move along with the rotation of the synchronous braking force transmitting member 112. This causes the inner brake cable 340 to actuate the front wheel brake 106 (not shown) simultaneously with the actuation of the rear wheel brake 108 (not shown). Thus, the synchronous brake assembly 104 of the present subject matter causes a simultaneous actuation of the rear wheel brake 108 and the front wheel brake 106, in no particular order.
[00041] Although the subject matter has been described in considerable detail with reference to certain embodiments thereof, other embodiments are possible. Rather, the features are disclosed as embodiments of the synchronous braking system 100.
