Technical Field

[0001] The utility model relates to the technical field of bearing brakes, in particular to a bearing brake structure for a three-wheeled motorcycle. Background Technique

[0002] The brake shoe of a tricycle is a key component for ensuring the braking performance of the tricycle. It directly frictions with the brake disc or brake drum to achieve the braking effect. The brake shoe is usually made of a specific material to ensure effective braking performance and wear resistance.

[0003] The brake shoe is usually installed on the brake drum. When braking, the brake shoe is pressed outwards and frictions the inner wall of the brake drum. The kinetic energy of the vehicle is converted into heat energy through the frictional force, enabling the tricycle to stop or decelerate quickly when needed. It is an indispensable part of the tricycle braking system and is directly related to driving safety.

[0004] However, it is found in the existing bearing brake structure of three-wheeled motorcycles that the conventional products on the market achieve braking by designing a straight surface rocker support plate and a straight surface rocker shaft. However, in the cooperation, the frictional force on the contact surface is large, it is too laborious to step on the brake, and it is easy to get stuck. The return is prone to jamming and is not smooth enough, and safety accidents are likely to occur during driving.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Content of the Utility Model
