[0002] Brakes installed in vehicles are known to sometimes produce undesired noise
For example, during slow forward motion, especially when the brake pads are in contact with the rotor, this unwanted noise can be produced, causing vibrations that often produce high frequency noise

Embodiment Construction

[0032] figure 1 A perspective view of the brake lining 100 is shown. The brake lining 100 includes a support body 10 in the form of a friction lining support plate and a friction lining 11 arranged on a first side surface of the support body 10 . The damping plate 16 is arranged on the side surface of the support body 10 facing away from the friction lining 11 (ie the second side surface of the support body) and is fixedly connected to the support body 10 .

[0033] The actuator 12 in the form of a piezoelectric element 18 a is arranged on the damping plate 16 . In this case, the piezoelectric element 18 a is glued to the damping plate 16 . The piezoelectric element 18a is connected to the control system 300 via connection elements 13a, 13b ( figure 1 not shown).

[0034] In this case, the actuator 12 is designed as a piezoelectric element 18a in such a way that when the actuator is excited by an alternating voltage and / or a noise signal, the piezoelectric element 18a mech...

Abstract

In order to further improve a brake lining comprising a support body and a friction lining arranged on the support body in such a manner that undesirable noises, in particular undesirable squealing can be avoided or reduced in as cost-effective as possible a manner, it is proposed for the noise reduction by means of a mechanical oscillation on or in the brake lining to arrange an actuator for generating the mechanical oscillation, wherein the actuator can be excited by an electrical signal.The invention also provides brake, control system and method for reducing noise of the brake.

Description

technical field [0001] The invention relates to a brake lining comprising a support body and a friction lining arranged on the support body. Background technique [0002] It is known that brakes installed in vehicles sometimes generate undesired noises. For example, during slow travel, especially when the brake pads are in contact with the rotor, this unwanted noise can be generated, causing vibrations that often generate high frequency noise. These undesired noises are often perceived as screeching. [0003] In order to avoid or reduce the undesired noise of the brakes, it is known to install damping material, for example, damping plates or damping plates on the brake lining, for example, damping plates or damping plates on the friction lining support plate of the brake lining. piece. Undesirable noise can thereby be reduced. [0004] Also, in order to further reduce noise generation, regular attempts are made to vary the geometry of the brake linings. Contents of the...
