Description

Technical Field

[0001] The present invention relates to the technical field of brake pads, and particularly to a structure and production process of a motorcycle brake pad. Background Art

[0002] ‌The motorcycle brake pad is an important component in the motorcycle braking system. Its main function is to convert the kinetic energy of the motorcycle into heat energy through friction, so as to achieve deceleration or parking. The brake pad is usually composed of a friction material and a back plate. When the brake pedal is depressed, the brake pad generates frictional force with the brake disc or brake drum through the clamping action of the brake caliper, thereby converting the kinetic energy of the motorcycle into heat energy to achieve the braking effect. The working principle of the brake pad is based on the friction principle. When the rider depresses the brake pedal, the brake caliper will clamp the brake pad, making it contact with the brake disc or brake drum and generate friction. This frictional force converts the kinetic energy of the motorcycle into heat energy, thus achieving the purpose of deceleration or parking.

[0003] In the prior art, the patent with the publication number: CN202301664U discloses an improved structure of a motorcycle brake shim, including an embedded piston, a shim, a brake pad lining, and a brake pad; the brake pad is installed on the brake pad lining; the shim is arranged between the embedded piston and the brake pad lining, and an axially extending section is formed on the shim, and the length of the extending section is greater than the thickness of the brake pad lining. The production process of the present utility model is simple, and it can effectively play a warning role for the wear degree of the brake pad.

[0004] Although the technical solution proposed by the above patent technology can effectively play a warning role for the wear degree of the brake pad, during the actual braking process, due to the relatively strong friction between the brake pad and the wheel hub assembly, a large amount of heat is generated on both the brake pad and the wheel hub.

In view of this, the present application proposes a structure and production process of a motorcycle brake pad. Summary of the Invention
