What is the brake structure of a motorcycle?
1 Answers
Motorcycle brake structure consists of a brake frame, brake components, and an operating device. Motorcycle Brake: The brake, commonly known as the stopping or decelerating mechanical component in machinery, is a crucial part ensuring the safe operation of a motorcycle and enabling it to come to a stable stop in the shortest possible time. Generally, for motorcycles with a displacement of less than 125ml, both front and rear wheels use drum brakes. For displacements between 125ml and 250ml, the front wheel employs a hydraulic brake, while the rear wheel uses a drum brake. Motorcycles with a displacement exceeding 250ml typically feature hydraulic brakes on both front and rear wheels. Drum Brake: Motorcycle drum brakes are mechanical brakes that can be used on the front wheel, rear wheel, or both. There are two types of drum brakes used in motorcycles: single-cam and double-cam. A motorcycle drum brake is composed of brake shoes, a brake cam, a brake drum, a brake arm, a brake drum cover, return springs, and a support shaft, among other components. In a drum brake system, the brake drum is mounted together with the wheel and rotates with it. The brake shoes are driven by the brake cam, and under the action of the return springs, the two brake shoes press tightly against the cam.
