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.
L'invention concerne un frein à friction présentant une garniture de frein dont la plaque support (1) est pourvue d'une garniture de friction (2). Deux résonateurs (3), décalés en diagonale l'un par rapport à l'autre, sont façonnés dans le matériau de la plaque support (1). Leur fréquence fondamentale est réglée sur la fréquence d'excitation de la plaque support (1) induite par la friction et leur surface est dimensionnée de telle manière que les ondes sonores générées se situent hors de la gamme audible pour l'homme. Les résonateurs (3) consomment l'énergie de vibration enregistrée dans la plaque support (1) sans générer de bruits audibles, ce qui stabilise le frein acoustiquement.
