Motorcycle hub brake device

Abstract

The invention relates to a motorcycle hub brake device. The device includes a brake drum, a brake disc and a lock mechanism, wherein the brake drum is arranged on a hub, and the lock mechanism is usedfor connecting the brake drum with the brake disc. The lock mechanism includes a lock ring arranged in the brake drum, brake shoe sets and a brake cover used for covering the brake drum; the lock ring is internally provided with several obliquely arranged lock grooves for accommodating the brake shoe sets, and a first connection mechanism is arranged between the lock ring and the brake cover formaking the lock ring and the brake cover connected. Through the cooperation of the lock ring and the brake shoe sets and the combination of the brake cover and the brake disc, an original drum brake is transformed into a rear wheel disc type brake device. According to the device, several parts are firmly fixed on an original brake hub, an original brake hub system can be converted into a disc typebrake system, hubs, steel rings and other parts do not need to be replaced, refit is very economical and affordable, and the device has all the performance of the rear wheel disc brake system uniqueto high-end motorcycles.

Description

technical field [0001] The invention relates to a brake device, in particular to a motorcycle hub type brake device. Background technique [0002] With the development of science and technology and the improvement of people's living standards, motorcycles have become the main means of transportation for urban and rural residents. Therefore, the stability and quality of motorcycle brakes are the key factors to ensure personal safety. Most vehicles on the market use The drum brake is used to brake the motorcycle. The drum brake is installed inside the wheel, and the heat dissipation is very poor, and the diameter of the brake drum will increase after being heated, which will increase the stroke when braking, and the brake response is not as expected. In addition, the response of the drum brake system is slow, and the braking force is difficult to control, which is not conducive to high-frequency braking action. There are also some motorcycles that use disc brakes. The disc bra...

[0002] With the development of science and technology and the improvement of people's living standards, motorcycles have become the main means of transportation for urban and rural residents. Therefore, the stability and quality of motorcycle brakes are the key factors to ensure personal safety. Most vehicles on the market use The drum brake is used to brake the motorcycle. The drum brake is installed inside the wheel, and the heat dissipation is very poor, and the diameter of the brake drum will increase after being heated, which will increase the stroke when braking, and the brake response is not as expected. In addition, the response of the drum brake system is slow, and the braking force is difficult to control, which is not conducive to high-frequency braking action. There are also some motorcycles that use disc brakes. The disc brakes are located outside the wheels, which have good heat dissipation, The brake is linear, easy to control, can be used for high-frequency point braking, and can be connected to ABS point braking, etc., so it is widely used in high-end motorcycles and cars
