Hydraulic cylinder assembly for linkage braking system and motorcycle comprising hydraulic cylinder assembly

Abstract

The invention discloses a hydraulic cylinder assembly for a linkage braking system and a motorcycle comprising the hydraulic cylinder assembly. The hydraulic cylinder assembly comprises a cylinder body and a piston positioned in the cylinder body, wherein an inner cavity of the cylinder body is divided into a working cavity for outputting hydraulic pressure and a driving cavity for inputting the hydraulic pressure and driving the piston to compress the working cavity; the piston is provided with a piston rod which extends out of the cylinder body along the axial direction and outputs the mechanical stroke of the piston; the hydraulic pressure output by the working cavity and the mechanical stroke output by the piston rod correspond to an output breaking force respectively; and the piston rod is provided with a pre-tightening force for driving the piston rod to return. By adoption of a structure of a cylinder assembly, the hydraulic cylinder assembly disclosed by the invention can reasonably distribute the braking forces of a front wheel braking component and a back wheel braking component, and can easily achieve a set linkage effect, increase the utilization ratio of attachment coefficients, increase the braking deceleration and reduce the braking distance; meanwhile, the system is simple in structure and sensitive in response, and can be easily adjusted according to required braking force distribution, so that the safety and the stability of motorcycle driving are increased.

Description

technical field [0001] The invention relates to a motorcycle component and its motorcycle, in particular to a motorcycle brake safety accessory and its motorcycle. Background technique [0002] The braking system is an indispensable safety accessory for motorcycles, which ensures that the driver and passengers have good control over the motorcycle and avoids safety accidents. Like other vehicles, motorcycles include front wheel brake components and rear wheel brake components. Front wheel brake components include front wheel brakes and front wheel brake drive transmission components, such as zippers or hydraulic cylinder assemblies. The driving components include the rear wheel brake and the front wheel brake drive transmission components; the front wheel brake components and the rear wheel brake components act independently, and the front wheel brake components cannot be distributed well when the ordinary driver brakes. The braking force of the brake assembly and the rear ...

AI Technical Summary

Problems solved by technology

Like other vehicles, a motorcycle includes a front wheel brake assembly and a rear wheel brake assembly. The front wheel brake assembly includes a front wheel brake and a front wheel brake drive transmission assembly, such as a zipper or a hydraulic cylinder assembly. The dynamic components include rear wheel brakes and front wheel brake drive transmission components; more brake drives are front wheel brake components and rear wheel brake components that act independently, and ordinary drivers cannot better distribute front wheel brakes when braking. The braking force of the moving component and the rear wheel brake component is only based on subjective operation; therefore, it has the disadvantages of low utilization rate of adhesion coefficient, small braking deceleration, long braking distance, etc., especially in the braking process, it is prone to unreasonable distribution of braking force Safety accidents such as rollovers

[0003] In the prior art, in order to solve the above problems, a series of linked brake devices have appeared; patent application 201110009654.7 discloses a motorcycle linked brake device, which can realize the linked brake operation of the front and rear wheels; the structure uses mechanical force to drive hydraulic pressure cylinder to achieve linkage braking, and set up auxiliary hydraulic cylinders to realize hydraulic and mechanical conversion to achieve the purpose of linkage; in order to rationally adjust and distribute the braking force, there are also delay valves and hydraulic suppression valves for adjusting hydraulic pressure output. The structure of the whole system is complex , the production is also more difficult, the cost is higher, and the adjustment process is more cumbersome; due to the use of the structure of the delay valve and the hydraulic suppression valve, the volume of the equipment is increased, and the response is not sensitive enough, it is difficult to achieve the desired effect, and deviations are prone to occur
