Technical Field

[0001] The utility model relates to the technical field of clutch brake structures, in particular to a brake friction plate with a reinforced fixed structure. Background Art

[0002] Friction pads are components consisting of a core plate and a friction lining, or layer of friction material. They are widely used in mechanical engineering, mechanical parts, and clutches. Also known as brake pads, friction pads are crucial safety components in automotive braking systems. They are a key component installed in braking systems, slowing and stopping the vehicle through friction against the brake disc or drum.

[0003] When the brake pedal is depressed, the brake pads clamp together, creating friction between them and the brake disc or drum. This friction converts the vehicle's kinetic energy into heat, thereby braking the vehicle. The quality and performance of the friction pads directly impact the effectiveness of braking, which in turn affects driving safety. Summary of the Invention
