Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle accessories, in particular to an adjustable rear brake assembly. Background Art

[0002] At present, the rear brake assembly installed on a motorcycle generally consists of a brake pedal, a cable mechanism, a main pump, an oil cup, a slave pump and a brake disc, among which the slave pump is installed next to the brake disc, and the slave pump is connected to the oil outlet of the main pump through a first oil pipe, the oil inlet of the main pump is connected to the oil cup through a second oil pipe, and the push rod of the main pump is connected to the brake pedal through a cable mechanism.

[0003] For example, patent number CN101804806A discloses a motorcycle rear brake assembly, including a brake pedal, a main pump, an oil cup, a slave pump and a brake disc, wherein the slave pump is installed next to the brake disc, the slave pump is connected to the oil outlet of the main pump through a first oil pipe, the oil inlet of the main pump is connected to the oil cup through a second oil pipe, the push rod of the main pump is hinged to the rear end of the pull rod through the rear rocker arm assembly, the front end of the pull rod is hinged to the lower end of the front rocker arm, and the upper end of the front rocker arm is hinged to the tail of the brake pedal.

[0004] In the above scheme, the brake pedal drives the rocker arm to rotate, so that the push rod at the bottom of the main pump is pushed upward, thereby pushing the hydraulic oil into the slave pump and braking the brake disc. However, in actual use, it is found that the speed of the hydraulic oil provided by the main pump to the slave pump cannot be adjusted, resulting in the length of the braking time of the brake disc cannot be adjusted, so the braking distance of the motorcycle cannot be adjusted, which cannot meet the needs of different drivers. For this reason, an adjustable rear brake assembly is proposed. Utility Model Content

[0013] Compared with the prior art, the utility model provides an adjustable rear brake assembly, which has the following beneficial effects:

[0014] The adjustable rear brake assembly is provided with an adjusting screw and an adjusting plate on the housing. When it is necessary to adjust the speed of the hydraulic oil provided by the main pump to the slave pump, the adjusting screw is turned by hand. When the adjusting screw is turned, the thread drives the adjusting plate to move upward or downward, thereby adjusting the size of the space inside the housing, changing the speed at which the hydraulic oil inside the housing enters the oil pipe, and further changing the speed at which the hydraulic oil is provided to the slave pump.

[0015] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model sets the speed of the hydraulic oil provided by the main pump to the slave pump to be adjustable, which can adjust the braking speed of the brake disc, thereby adjusting the braking distance of the motorcycle.
