Linked braking device of all-terrain vehicle and all-terrain vehicle

Abstract

The invention relates to a linked braking device of an all-terrain vehicle and the all-terrain vehicle. The linked braking device of the all-terrain vehicle comprises a hand-operated braking system and a foot-operated brake driving component, wherein the hand-operated braking system comprises a front hand-operated brake driving component, a back hand-operated brake driving component, a front wheel braking assembly and a back wheel braking assembly, and the front wheel braking assembly and the back wheel braking assembly are correspondingly driven by the front hand-operated brake driving component and the back hand-operated brake driving component and are used for forming the operation of braking on the front wheels and the back wheels of a vehicle; the foot-operated brake driving component is used for distributing braking force to the front wheel braking assembly and the back wheel braking assembly so as to form linkage with the hand-operated braking system; the independent braking of the front wheels and the back wheels and the operation of foot braking are realized by the hand-operated braking device according to the linked braking device, so that the magnitude of the braking force is enhanced; meanwhile, a mechanical linked braking device is adopted, the connecting points of three-way pipes are reduced, the leakage of hydraulic oil is reduced, and a more reliable braking system is provided; and meanwhile, the manufacturing difficulty is reduced, and the manufacturing cost is lowered.

Description

technical field [0001] The invention relates to a braking system of an all-terrain vehicle, in particular to a linkage braking device of an all-terrain vehicle. Background technique [0002] The all-terrain vehicle is a kind of sports and entertainment vehicle suitable for various road types. It is the recreational nature of the vehicle that determines the importance of the braking system of the all-terrain vehicle. The braking system of the existing all-terrain vehicle mainly adopts the handbrake operating device to control the braking of the two front wheels, and the foot brake device controls the braking of the two rear wheels. The brake pump generates fluid pressure, and then controls the brakes of the front wheels through the front wheel splitter to complete the front wheel braking; the hydraulic pump of the foot brake device is connected to the foot brake shunt pump to generate fluid pressure to control the rear wheel braking; since only the front wheel is used Brakin...

Problems solved by technology

The braking system of the existing all-terrain vehicle mainly adopts the handbrake operating device to control the braking of the two front wheels, and the foot brake device controls the braking of the two rear wheels. The brake pump generates fluid pressure, and then controls the brakes of the front wheels through the front wheel splitter to complete the front wheel braking; the hydraulic pump of the foot brake device is connected to the foot brake shunt pump to generate fluid pressure to control the rear wheel braking; since only the front wheel is used Braking and rear wheel braking separate braking mode, front wheel braking is prone to front wheel locking, resulting in the loss of steering ability of the vehicle and making the vehicle unable to deal with danger in time

In order to improve the braking, the above-mentioned structure is improved, using foot brake combined braking, adding a set of hydraulic braking system and front splitter pump, although this structure increases the braking force compared with the previous independent control of the front and rear wheels, it has certain advantages. Improvement, but a set of brake system is added, which increases the manufacturing cost more, and oil leakage is easy to occur at the junction of the rear brake oil pipe and the front brake fluid.
