METHOD AND DEVICE FOR REDUCING OR PREVENTING NOISE DEVELOPMENT OF FRICTION BRAKES AND FRICTION CLUTCHES.

摘要

The friction brake is provided with a brake lining. The support plate (1) of said brake lining is provided with a friction lining (2). Two resonators (3) which are diagonally displaced against each other are formed in the material of the support plate (1). The natural frequency of the resonators (3) is adjusted to the friction induced excitation frequency of the support plate (1). The surfaces of the resonators (3) are dimensioned in such a way that the sound waves thus generated lie beyond the human hearing range. The resonators (3) use the vibration energy which is supplied to the support plate (1) without causing audible noises. Hence, the brake is acoustically attenuated.
