Abstract

The invention discloses an organic synthesis friction body, a brake pad and a preparation method of the organic synthesis friction body and the brake pad, and relates to the field of traffic part machining and manufacturing. According to the brake pad, it is ensures that the brake pad has the characteristics of being wear-resistant and low in thermal conductivity, the brake pad is not prone to generating abnormal wear and noise, the problems of brake distance deviation and brake pad abnormal wear during the braking process of the powder metallurgy brake pad are solved, and the influence of thebrake pad on the rotating speed of a motor is reduced. The brake pad comprises a steel back, the organic synthesis friction body, a plurality of fixing rings and a plurality of material grabbing pins, wherein the organic synthesis friction body is an integrated organic synthesis friction body, the multiple fixing rings and the multiple material grabbing pins each are fixed to the steel back, andthe organic synthesis friction body is fixed to the steel back with the multiple material grabbing pins. The brake pad is applied to urban rail transit transportation aspects.

Description

technical field [0001] The invention relates to the field of processing and manufacturing parts of transportation products, in particular to an organically synthesized friction body, a brake pad and a preparation method thereof. Background technique [0002] With the advancement of science and technology and the development of urban rail transit, the straddle-type monorail transit system has gradually matured and improved. Compared with traditional double-track trains, straddle-type monorail trains have many advantages such as strong adaptability, low noise, small turning radius, and very strong climbing ability. The straddle-type monorail train uses a hydraulic braking system instead of the pneumatic braking system of traditional double-track trains. And due to the limitation of the space structure, the brake disc of the straddle monorail train is placed between the motor and the reducer. This structure means that the brake pads of the straddle monorail train need to face ...
