Automobile Damping and Silencing Sheet DC40-02C

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

Automotive vibration-damping noise suppression components serve as essential elements in braking systems to mitigate operational acoustics. Functioning as a critical brake assembly element, this noise-control layer is mounted on the brake pad's steel backing plate. During braking maneuvers, it effectively attenuates vibrational energy and acoustic emissions generated by friction interactions within the system. A complete brake unit typically comprises three primary sections: the friction contact surface (brake lining), structural support base (metal substrate), and integrated noise-reduction modules.

Noise attenuation mechanism: Brake-generated sound originates from oscillatory friction between the contact material and rotor surface. Acoustic wave propagation undergoes dual-phase modification - initially through transmission from the friction interface to the metallic substrate, then subsequently through the sound-absorbing layer. This multi-stage energy dissipation process achieves noise reduction through two primary physical phenomena: interlayer acoustic impedance mismatching that disrupts wave transmission continuity, and strategic resonance frequency separation through specific structural design parameters.

Products Feature

The metal substrate has a thickness ranging from 0.2mm to 0.8mm, with a maximum width of 1000mm. The rubber coating thickness falls between 0.02mm and 0.12mm. Both single-sided and double-sided NBR rubber-coated metal materials are available to meet diverse customer needs. These materials offer excellent shock absorption and noise reduction capabilities, and are cost-effective alternatives to imported materials.

The material surface undergoes anti-scratch treatment, ensuring high scratch resistance. Additionally, the surface color can be tailored to customer preferences, offering options such as red, blue, silver, and other non-transmissible hues. Upon request, we can also manufacture cloth-patterned coated sheets without any grain texture.
