, Description:FIELD OF THE INVENTION
[0001] The present subject matter, in general relates to a braking system, and in particular, relates to a mounting assembly of a synchronized braking system for a multi wheeled vehicle.
BACKGROUND OF THE INVENTION
[0002] Generally, motor vehicles are provided with a braking system, which is used for slowing down the motor vehicle and / or for bringing the motor vehicle to a complete halt. Be it a mono-cycle or a multi-wheeled vehicle, all the motor vehicles incorporate a braking system. Generally, multi-wheeled vehicles, especially, motor vehicles having a plurality of wheels incorporate various electronics based braking systems like anti-lock braking system (ABS), electronic brake-force distribution (EBD) etc., which operate based on complex electronics. Two-wheeled or three-wheeled motor vehicles, catering to commuter applications, popularly incorporate a braking system that allows simultaneous application of a front wheel brake and a rear wheel brake by actuation of a single brake lever referred as combined braking system.

DETAILED DESCRIPTION OF THE INVENTION
[0008] Conventionally, two-wheeled or three-wheeled motor vehicles are considered to be less stable when compared to motor vehicles having four or more wheels. Hence, braking system plays a crucial role in slowing down or in bringing the motor vehicle to a safe halt effectively. Generally, in the two-wheeled or three wheeled motor vehicles, a disc brake or a drum brake is provided to operate as a front wheel brake and a drum brake is provided to operate as a rear wheel brake.
[0009] For example, the disc brake is provided as front wheel brake in motor vehicles that operate at high-speeds. Moreover, in case of high-speed applications, the rear wheel is also configured with a disc brake. Conventionally, a hand-operated lever or a foot-operated lever is used for actuation of the brakes.
[00010] In order to simultaneously operate both the front wheel brake and the rear wheel brake, a brake force distribution member like an equalizer is typically used in some braking system known in the art. The equalizer and corresponding cables or hose connections cannot be accommodated near a handle bar, where a hand operated brake lever is disposed, or near a rider foot-peg/ foot-rest, where a foot operated brake lever is disposed. Moreover, the equalizer-based system may require a separate space / casing on the motor vehicle away from the handle bar or the rider foot-peg. Provision of such aforementioned braking system that simultaneously operates the front wheel brake and the rear wheel brake upon actuation of the single brake lever is a major challenge due to space constraints. For example, the handlebar already incorporates various system like switches, head lamp assembly, a cover or casing, display etc. Moreover, equalizer-based systems work on principle of brake force distribution, which may require the user to apply more braking force for application of brakes.
[00011] Further, in a vehicle comprising of a drum brake for the rear wheel and a drum / disc brake for the front wheel in a combined brake system for a two wheeled vehicle, there exists a brake pedal bracket, to which brake pedal and synchronous braking brake cable is assembled, the brake pedal bracket being mounted to a shaft which is welded to a portion of a frame assembly.
[00012] Several issues have been encountered due to attachment of the brake pedal bracket to the portion of the frame assembly. The issues that are to be addressed includes, the load exerted on the brake pedal from the rider, either operated through foot or hand, is experienced by a portion of the brake pedal bracket that is on contact with the brake pedal. The load experienced by the brake pedal, is for example, maximum of 100kgs and thickness of the brake pedal bracket is for example, 1mm, the brake pedal bracket is unable to bear the load transferred from the brake pedal over a long duration of usage. To address the problem, the thickness and size of the brake pedal bracket may be increased, however, the packaging and mounting of the bigger brake pedal bracket is challenging, as it involves increase in mounting joints between the brake pedal bracket and the portion of the frame assembly. Further, the packaging of the brake pedal bracket with bigger thickness and size in the vehicle layout poses problems such as increased width in the vehicle, which is undesirable.
[00013] Further, the bigger mounting portion of the brake pedal bracket with the frame assembly is undesirable due to weld distortions that occur during attachment of a thicker brake pedal bracket with the frame assembly. A phenomenon called as weld spatter is also observed around the region of welded portion, as a result of which the desired perpendicularity of the mounting surface is lost. Further, the uneven surface due to weld spatter weakens the welded joint, because of which, individual movement of the sub-parts of brake assembly along vehicle width direction occurs. As a result of which, entire braking system in the vehicle fails.
[00014] In order to over come weld spatter around the welded region, polishing of the surface is carried out to enable the surface being perpendicular, however the polishing includes additional cost, labour, and time. Therefore, welded attachments are not desirable.
[00015] Further, the bigger brake pedal bracket causes space constraints around brake pedal area and not being able to be packaged and mounted to the frame assembly of the vehicle, further, the brake pedal braket increases the weight of the frame assembly and load coming to the frame and the welding drawbacks like pin warpage, weld spatter etc. which in turn creates poor brake performance as well as safety risk.
[00016] Poor aesthetics as the brake parts are visible outside, Dust, mud and stone affecting the parts of the brake assembly as the brake assembly parts are visible outside, this calls for frequent servicing and additional cost to the user, therefore, not economically significant.
[00017] Hence, there exists a challenge to provide a braking mounting system that is capable of actuating front wheel brake and rear wheel brake simultaneously. It should be capable of being accommodated on a compact two-wheeled or three-wheeled motor vehicle by occupying less space and by utilizing a smaller number of components without any compromise on braking effectiveness and safety.
[00018] Thus, the present subject matter provides a braking system that addresses the aforementioned and other problems in the prior arts.
[00019] According to an embodiment of the present invention, a brake mounting assembly for a vehicle is disclosed which comprises of a brake assembly for synchronously controlling rotational movement of multi wheels of the vehicle.
