Definitions

  • the present subject matter described herein in general relates to a saddle type vehicle and more particularly but not exclusively to braking system for the saddle type vehicle.
  • saddle type vehicles are provided with a braking system for slowing or stopping the vehicle.
  • the braking system usually, includes a front wheel brake and a rear wheel brake for a front wheel and a rear wheel, respectively. Further, each of the front wheel brake and the rear wheel brake is connected to at least one brake lever for actuation.
  • the brake lever enables actuation of the wheel brake.
  • the brake lever is connected to the wheel brake for applying friction to each wheel of the saddle type two-wheeled vehicle, as and when required.
  • the brake lever can be connected to the wheel brake in a variety of ways.
  • the brake lever can be connected to the wheel brake by means of a cable.
  • one end of the cable may be secured to the wheel brake, 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. Nevertheless, the brake assembly can be connected to the lever by means of hydraulic system also. Furthermore, in some applications, combination of the cable and the hydraulic means is used.

  • a front brake lever and a rear brake lever is mounted to a handle bar of the vehicle and a rear brake lever is mounted to either the handle bar or to the vehicle structure for actuating the front wheel brake and the rear wheel brake respectively.
  • brake actuation assembly is also mounted to the handle bar or to the vehicle structure.
  • riders may apply mostly the rear wheel brake lever alone.
  • Such a practice stems from the fact that actuating both the brake levers at the same time may be inconvenient for the novice rider.
  • the rear brake lever is provided with actuation of both front wheel brake and rear wheel brake. Accordingly, upon actuation of the single/rear brake lever, such a braking system may allow distribution of braking force to the front wheel as well as the rear wheel of the vehicle.
  • the above said assembly improves the braking even while using one of the brake controls only, and avoids any sudden wheel locking during emergency and panic conditions even while using one of the brake controls only, under such conditions, the wheel locking is postponed by providing additional support of braking from the other wheel as well.
  • an application of one of the brake controls alone does not provide safety during panic or emergency conditions as most of the riders, in the learning stage use only rear brake controls.
  • such an assembly cannot prevent front wheel from locking during emergency and panic situations. The risk of front wheel locking is higher than that of rear wheel, but cannot be prevented even while using rear brake control alone.
  • the braking assembly including a single-channel anti-lock braking system is also known.
  • ABS anti-lock braking system
  • the braking assembly with ABS prevents at least one of both the wheels from locking and also prevents over- throw whenever front wheel brakes are applied for the case of front wheel control ABS.
  • the braking assembly with single channel ABS includes certain disadvantages, some of them being, there is no significant improvement in braking and thereby required safety is not provided to novice riders while applying brakes in the vehicle, further, the locking of the rear wheel during emergency and panic situations is not prevented in case of novice riders.
  • the braking performance cannot be improved for novice riders as long as rear brake controls only are used, since crash control cannot be prevented. Further, for novice riders, usage of both brake controls along with the throttle control is difficult.
  • the braking assembly including three-channel ABS is also known which involves controlling both the front as well as the rear brakes through combined braking system in addition to ABS control for each of the front & rear wheels.
  • the braking control system including three-channel ABS provides improved safety by preventing locking of wheels and in addition provides shorter rear braking distance.
  • a proportionate valve is not required since calliper size -ratio controls the front-to-rear braking ratio.
  • such a configuration has the disadvantage of compulsion of including a divided/3-pot calliper at front brake, an exclusive delay vale and an additional ABS channel and 1 -channel.
  • the three-channel ABS is expensive compared to the other 2(dual)-ABS channel and 1 (single)-channel assemblies, due to complex circuitry.
  • the battery in the vehicle is overloaded due to presence of third-channel ABS control.
  • the braking assembly controlling braking forces to the front wheel and the rear wheel is controlled by the combined braking system as well as antilock braking system.
  • Such an assembly provides improved safety to the riders.
  • such an assembly includes an extra ABS channel making the assembly more complex and expensive. Further, the battery life in the vehicle is also reduced due to presence of too many systems.
  • a simpler braking assembly comprising simpler circuitry and reduced number of parts and reduced cost is required.
  • the present subject matter provides such a system.
  • the braking of the front wheel and the rear wheel is simultaneously achieved.
  • the braking system of the present invention overcomes wheel locking on at least one of the front wheel and the rear wheel without the need for additional complex circuitry.
  • Fig. 1 illustrates a side view of a two-wheeled vehicle, for example, a motorcycle 100 according to an embodiment.
  • the motorcycle 100 according to an embodiment includes a front wheel 11 steered by a handlebar 13 and a rear wheel
  • a seat 10 for a driver with or without a pillion is placed rearward to a fuel tank 18.
  • An engine assembly 16 is disposed below the fuel tank 18.
  • a front fender 20 is provided above the front wheel 11 to avoid the motorcycle 100 and its occupants from being splashed with mud.
  • a rear fender 19 is placed above the rear wheel 12, and to the outer side in the radial direction of the rear wheel 12. The rear fender 19 inhibits rainwater or the like from being thrown up by rear wheel 12.
  • the swing arm 14 along with a shock absorber 21 is supported at a front portion thereof for pivotal motion and upward and downward rocking motion on the rear side of a lower portion of the vehicle body frame 17.
  • a suspension assembly including a pair of front forks 22 and the shock absorber 21 is provided in the motorcycle 100 for providing better ride comfort to the rider and the pillion rider.
  • the shock absorbers help cushion vehicles on uneven roads.
  • shock absorbers reduce the effect of travelling over rough ground, leading to improved ride quality and vehicle handling.
  • the vehicle body frame 17 includes the head pipe 15, a main frame (not shown).
  • the head pipe 15 is positioned at a front-end portion of the vehicle body frame 17. Also includes pair of down frames extending in a leftwardly and rightwardly branching state obliquely downwardly rearwardly from a lower portion of the head pipe 15.

Description

A SADDLE TYPE VEHICLE
TECHNICAL FIELD
[0001] The present subject matter described herein in general relates to a saddle type vehicle and more particularly but not exclusively to braking system for the saddle type vehicle.
BACKGROUND
[0002] Conventionally, saddle type vehicles are provided with a braking system for slowing or stopping the vehicle. The braking system, usually, includes a front wheel brake and a rear wheel brake for a front wheel and a rear wheel, respectively. Further, each of the front wheel brake and the rear wheel brake is connected to at least one brake lever for actuation. The brake lever enables actuation of the wheel brake. For example, the brake lever is connected to the wheel brake for applying friction to each wheel of the saddle type two-wheeled vehicle, as and when required. The brake lever can be connected to the wheel brake in a variety of ways. For example, the brake lever can be connected to the wheel brake by means of a cable. In such a case, one end of the cable may be secured to the wheel brake, 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. Nevertheless, the brake assembly can be connected to the lever by means of hydraulic system also. Furthermore, in some applications, combination of the cable and the hydraulic means is used.

DETAILED DESCRIPTION
[00017] Generally, in saddle type two or three- wheeled vehicles, a front brake lever and a rear brake lever is mounted to a handle bar of the vehicle and a rear brake lever is mounted to either the handle bar or to the vehicle structure for actuating the front wheel brake and the rear wheel brake respectively. Even in case of braking systems involving braking of both front wheel brake and rear wheel brake upon actuation of one brake lever, such brake actuation assembly is also mounted to the handle bar or to the vehicle structure. During operation of the brakes, usually, riders may apply mostly the rear wheel brake lever alone. Such a practice stems from the fact that actuating both the brake levers at the same time may be inconvenient for the novice rider. In addition, when any hard braking is applied on the front wheel alone, less grip initially on the front wheel and excess 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. Therefore, the rear brake lever is provided with actuation of both front wheel brake and rear wheel brake. Accordingly, upon actuation of the single/rear brake lever, such a braking system may allow distribution of braking force to the front wheel as well as the rear wheel of the vehicle. [00018] The above said assembly improves the braking even while using one of the brake controls only, and avoids any sudden wheel locking during emergency and panic conditions even while using one of the brake controls only, under such conditions, the wheel locking is postponed by providing additional support of braking from the other wheel as well. However, such an application of one of the brake controls alone does not provide safety during panic or emergency conditions as most of the riders, in the learning stage use only rear brake controls. Further, such an assembly cannot prevent front wheel from locking during emergency and panic situations. The risk of front wheel locking is higher than that of rear wheel, but cannot be prevented even while using rear brake control alone.
[00019] Further, the braking assembly including a single-channel anti-lock braking system (ABS) is also known. The braking assembly with ABS prevents at least one of both the wheels from locking and also prevents over- throw whenever front wheel brakes are applied for the case of front wheel control ABS. However, the braking assembly with single channel ABS includes certain disadvantages, some of them being, there is no significant improvement in braking and thereby required safety is not provided to novice riders while applying brakes in the vehicle, further, the locking of the rear wheel during emergency and panic situations is not prevented in case of novice riders. Furthermore, the braking performance cannot be improved for novice riders as long as rear brake controls only are used, since crash control cannot be prevented. Further, for novice riders, usage of both brake controls along with the throttle control is difficult.
[00020] Furthermore, the braking assembly including three-channel ABS is also known which involves controlling both the front as well as the rear brakes through combined braking system in addition to ABS control for each of the front & rear wheels. The braking control system including three-channel ABS provides improved safety by preventing locking of wheels and in addition provides shorter rear braking distance. Further, for one of such a configuration, a proportionate valve is not required since calliper size -ratio controls the front-to-rear braking ratio. However, such a configuration has the disadvantage of compulsion of including a divided/3-pot calliper at front brake, an exclusive delay vale and an additional ABS channel and 1 -channel. Furthermore, the three-channel ABS is expensive compared to the other 2(dual)-ABS channel and 1 (single)-channel assemblies, due to complex circuitry. Furthermore, the battery in the vehicle is overloaded due to presence of third-channel ABS control.
[00021] Furthermore, the braking assembly controlling braking forces to the front wheel and the rear wheel is controlled by the combined braking system as well as antilock braking system. Such an assembly provides improved safety to the riders. However, such an assembly includes an extra ABS channel making the assembly more complex and expensive. Further, the battery life in the vehicle is also reduced due to presence of too many systems.
[00022] Therefore, a simpler braking assembly comprising simpler circuitry and reduced number of parts and reduced cost is required. The present subject matter provides such a system. In accordance to an embodiment of the present invention, the braking of the front wheel and the rear wheel is simultaneously achieved. The braking system of the present invention overcomes wheel locking on at least one of the front wheel and the rear wheel without the need for additional complex circuitry.
[00023] These and other advantages of the present subject matter would be described in greater detail in conjunction with the figures in the following description.
[00024] Fig. 1 illustrates a side view of a two-wheeled vehicle, for example, a motorcycle 100 according to an embodiment. The motorcycle 100 according to an embodiment includes a front wheel 11 steered by a handlebar 13 and a rear wheel
12 supported by a swing arm 14. Steering assembly parts including the handlebar
13 and the front wheel 11 are supported for pivotal steering operation on a head pipe 15 at a front end of a vehicle body frame 17. A seat 10 for a driver with or without a pillion is placed rearward to a fuel tank 18. An engine assembly 16 is disposed below the fuel tank 18. A front fender 20 is provided above the front wheel 11 to avoid the motorcycle 100 and its occupants from being splashed with mud. Likewise, a rear fender 19 is placed above the rear wheel 12, and to the outer side in the radial direction of the rear wheel 12. The rear fender 19 inhibits rainwater or the like from being thrown up by rear wheel 12.
[00025] The swing arm 14 along with a shock absorber 21 is supported at a front portion thereof for pivotal motion and upward and downward rocking motion on the rear side of a lower portion of the vehicle body frame 17. A suspension assembly including a pair of front forks 22 and the shock absorber 21 is provided in the motorcycle 100 for providing better ride comfort to the rider and the pillion rider. In general terms, the shock absorbers help cushion vehicles on uneven roads. In the two-wheeled vehicle, shock absorbers reduce the effect of travelling over rough ground, leading to improved ride quality and vehicle handling. The vehicle body frame 17 includes the head pipe 15, a main frame (not shown). The head pipe 15 is positioned at a front-end portion of the vehicle body frame 17. Also includes pair of down frames extending in a leftwardly and rightwardly branching state obliquely downwardly rearwardly from a lower portion of the head pipe 15.
[00026] According to an embodiment, a front braking system 106 enables braking of the front wheel including at least one disc brake for enabling braking of the front wheel 11.
[00027] Fig. 2 illustrates a block diagram of a single channel interlock-antilock braking system connected to a front wheel brake system. According to an embodiment of the present invention, the two-wheeled vehicle, for example the motorcycle includes one or more levers for actuating at least one of the front brake system, a rear brake system, or both, which includes a front brake control 102 and a rear brake control 101. The front brake control 102 and the rear brake control 101 are connected to an interlock- antilock braking system 150. The interlock- antilock braking system 150 includes an interlock braking system 103 interlinked with an antilock braking system 104. The interlock braking system 103 receives braking inputs at least from the front brake control 102 and the rear brake control 101 and actuates both the front braking system 106 and the rear braking system 105 simultaneously. Further, one of the outputs of the interlock braking system 103 is provided to an antilock-braking system 104 and the other output is directly received by the rear braking system 105. The output of the interlock braking system 103 received by the antilock braking system 104 is further fed to the front braking system 106. Such an output from the antilock braking system 104 is capable of preventing 1 the front wheel 11 from locking under panic braking conditions and prevents any jerking of the vehicle and provides safety to the rider. Furthermore, the output of the interlock braking system 103 provides simultaneous braking of the front wheel 11 and the rear wheel 12 upon actuation of any one of the levers of the rear brake control 101 and the front brake control 102. Therefore, by usage of the interlock- antilock braking system 150 in a two-wheeled vehicle, simultaneous braking of both the front wheel 11 and the rear wheel 12 by actuation of only one lever of the one or more levers along with prevention of locking of the front wheel 11 can be achieved.
[00028] According to an embodiment of the present invention, the interlock- antilock braking system 150 includes a simpler circuitry and is cost effective as it does not include a separate channel for usage of the antilock braking system 104 for interlock control.
[00029] According to an embodiment of the present invention, the front brake control 102 and the rear brake control 101 are hand operated. The front braking system 106 includes at least one disc brake and the rear braking system 105 includes at least one drum brakes. The front brake control 102 is capable of actuating the front braking system 106 and the rear brake control 101 is capable of actuating the rear braking system 105.
