Problems solved by technology

Due to the limitation of the material formula, the shaft brake disc friction plates currently used in the market are all in use, but the achievable braking torque is relatively not very stable, and there are also problems such as the friction plates sticking to water, and the brake noise is loud.
In order to solve this problem, most manufacturers choose to purchase imported friction plates. While bearing huge costs, they have not completely solved the problems of water adhesion and loud brake noise.

Abstract

The invention discloses a low-noise friction plate for a brake. The low-noise friction plate for the brake comprises, by weight, 33-35 parts of buna-n rubber, 7-9 parts of thermosetting phenolic resin, 24-26 parts of enhanced non-asbestos fibers, 14-16 parts of granulated cork, 4-6 parts of metal powder, 4-6 parts of artificial graphite, 4-6 parts of barium sulfate and 2-4 parts of other impurities. According to the low-noise friction plate for the brake, the formula is advanced, the braking torque is high and stable, the temperature resistance can reach 250 DEG C, the abrasion rate is low, a high friction coefficient and the low abrasion rate can still be guaranteed while the hardness is reduced, braking noise is effectively lowered by 20 dB, the problem that the friction plate adheres when encountering water is completely eradicated, and promotion of the braking performance of a horizontal type main machine is facilitated.

Description

technical field [0001] The invention relates to the field of friction lining production, in particular to a low-noise friction lining for brakes. Background technique [0002] At present, the relative hardness of the friction plate used in the market is between HD65-75. As a disc friction plate for axle brake, it has high hardness and high density, which is to reduce the wear rate, increase the friction coefficient, and increase the braking torque. However, the friction plate with relatively high hardness has a poorly processed effective fitting surface, resulting in unstable braking torque, and due to its relatively high hardness, the braking noise is also relatively large. [0003] At present, the permanent magnet synchronous inner rotor main engine has been more and more recognized by the market. It adopts a horizontal structure, and the magnetic circuit smell does not change after mounting, and the operation is stable. More importantly, the horizontal main engine adopts ...
