Automobile Damping and Silencing Sheet DC40-03B43

Short Description:

The automobile damping and silencing pad is an accessory used to reduce or eliminate the noise during brak-ing. It is an important component of the automobile brake pad. It is arranged on the steel back of the brake pad. When the brake pad is braking,it plays a certain damping effect on the vibration and noise caused by the brakepad pad pad. The brake system is mainly composed of brake lining (friction material), steel back (metal part) and damping and silencing pads.

Products Description

The automotive shock-absorbing and sound-deadening pad is a critical accessory engineered to minimize or eliminate noise during vehicle braking. As an integral part of automobile brake pads, it is mounted onto the steel backing of the brake pad assembly. When the brake pads engage, the pad effectively absorbs vibrations and suppresses noise generated by friction between the brake pad and rotor. The automobile brake system primarily comprises three components: the friction lining (friction material), the steel backing (metal part), and the vibration-damping mat, which work collaboratively to ensure optimal braking performance and passenger comfort.

Silencing Principle
Brake noise originates from friction-induced vibrations between the friction lining and the brake disc. Sound waves undergo two critical impedance changes as they propagate: first, when transmitted from the friction lining to the steel backing, and second, when transmitted from the steel backing to the damping pad. The phase impedance mismatch between these layers, combined with resonance avoidance, effectively attenuates noise. This scientific principle ensures that our damping pads deliver superior noise reduction in real-world driving conditions.
