Anti-slip structure between the sound-damping layer and the back plate of an electromechanical brake pad

By using internal and external elastic pushers in the electromechanical brake to push the back plate and the mounting bracket spring sheet into contact, the problem of slippage between the internal and external sound-absorbing layers and the back plate is solved, achieving noise control and safety improvement.

AI Technical Summary

Technical Problem

In electromechanical brakes, relative slippage can easily occur between the inner silencing layer and the inner back plate, as well as between the outer silencing layer and the outer back plate, leading to increased braking noise and safety hazards.

Method used

An inner elastic pusher and an outer elastic pusher are fixed to the inner back plate and the outer back plate respectively. By pushing the back plate before braking, it is made to fit against the spring sheet on the mounting bracket to prevent slippage during braking.

Benefits of technology

It effectively suppresses the relative slippage between the inner sound-absorbing layer and the inner back plate, and between the outer sound-absorbing layer and the outer back plate, preventing noise increase and safety hazards, and ensuring the stability and noise control of the brake pads.

Abstract

The application discloses a kind of anti-slippage structure between the sound-absorbing layer of electromechanical brake pad and backboard, including inner elastic pusher and outer elastic pusher;The inner elastic pusher one end is fixed in the inner backboard inner screw-in end position, and the other end is fixedly connected with the inner spring piece of corresponding side on mounting bracket, and the inner elastic pusher is in compression state and moves the inner backboard to the inner screw-out end side before braking, so that the inner screw-out end is attached to the inner spring piece of the other side on mounting bracket;The outer elastic pusher one end is fixed in the outer backboard outer screw-in end position, and the other end is fixedly connected with the outer spring piece of corresponding side on mounting bracket, and the outer elastic pusher is in compression state and moves the outer backboard to the outer screw-out end side before braking, so that the outer screw-out end is attached to the outer spring piece of the other side on mounting bracket.It can effectively inhibit the relative slippage between the inner sound-absorbing layer and the inner backboard, and can effectively inhibit the relative slippage between the outer sound-absorbing layer and the outer backboard.
