In order for a carrier body, which has a friction pad carrier plate (10) and at least one first absorber mass (14) rigidly connected to the friction pad carrier plate, to be further improved in such a way that the rigid connection between friction pad carrier plate and the first absorber mass is made more robust, provision is made for a first pin-like projection (18) of the first absorber mass (14) to be inserted into the first hole of the friction pad carrier plate (10) such that the head (28) of the first pin-like projection (18) protrudes out of the first hole and bears partially against a first chamfer (26) in the region of a first edge (22) of the first hole.

A drum brake assembly and method for designing the assembly are provided. The assembly includes a brake spider, a pair of brake shoes pivotally coupled to the brake spider at one end, and a pair of cam followers disposed at opposite ends of the brake shoes. The assembly further includes a camshaft having a shaft disposed along a rotational axis and a cam disposed at one end of the shaft. The cam has an inboard side proximate the shaft, an outboard side distant from the shaft and a cam surface extending between the inboard and outboard sides in engagement with the cam followers. The camshaft further includes a noise reducing mass disposed on the outboard side of the cam. The mass is configured to establish a natural frequency in the cam that differs from a natural frequency of the first and second brake shoes to reduce audible noise.

In order to further improve a method for producing a carrier body for a friction lining of a disk brake, in such a way that the rigid connection between a friction-lining carrier plate of the carrier body and a first damper mass of the carrier body is more robust, a force directed perpendicularly towards the first pin-shaped project is exerted, according to the invention, by means of pressing until the first pin-shaped projection is compressed to such an extent that the first pin-shaped projection forms, within the first hole, a form closure with an inner wall of the first hole in some regions.

A disclosed brake lining includes first and second friction member blocks, fastening members, spring members disposed in the fastening members, and a base plate. Each of the first friction member blocks including friction members is elastically fastened to the base plate by two of the fastening members that pass through the spring member and a first back plate. The two of the fastening members are disposed along a circumference of a circle centered around an axle. Each of the second friction member blocks including friction members is elastically fastened to the base plate by three of the fastening members that pass through the spring member and a second back plate. Two of the fastening members lying on opposite ends of each of the second friction member blocks are disposed along a circumference of a circle around the axle.

The invention relates to a motor vehicle actuator, in particular a brake actuator, comprising a housing (3) which consists of a housing container (1) and a housing cover (2) designed as a base support, and in which an electric motor (4) and a transmission (6) coupled to the electric motor via a torque transmitting device (5) are arranged. A retaining frame which can be arranged on the housing cover (2) is provided in order to arrange the electric motor (4) within the housing (3). The invention is characterized in that the holding frame (7) is designed as a damping and/or spring device.

This brake lining includes: a plurality of friction members which are arranged to be spaced from each other, each of the friction members having a front surface that is to face a sliding surface of a brake disk; a back board fastened to a back surface of each of the friction members; a base plate that supports each of the friction members at a region including a center portion of each friction member; and an elastic member disposed between the base plate and the back board, on a back surface side of each friction member. Two friction members that are adjacent to each other are taken as a pair, and the back board is fastened to each of the pairs of friction members. In each pair of friction members, the two friction members are arranged along the circumferential direction of the brake disk.

A disk brake, in particular for a vehicle, comprising a brake lining arrangement with a friction lining and a pad back plate. The friction lining can interact with a brake disk in order to achieve a braking effect. The disc brake also comprises a vibration damping device which is arranged on a brake caliper or on a brake support, comprising at least one additional mass which is designed as a separate component. The vibration damping device further comprises a receiving pin which is secured to the brake caliper or to the brake support and via which the additional mass can be fixed to the brake caliper or to the brake support.

Friction assembly (1) comprising a support plate (2) and at least one brake pad (4), made by co-molding of at least one heat-resistant resin, the heat-resistant resin of the support plate (2) being partially loaded with non-metallic reinforcement fibers. The support plate (2) identifies one or more accessory-connection seat, made by co-molding. This invention further relates to a method for the manufacture of a friction assembly and a brake calliper.

A brake shoe for a drum brake includes a brake table and one or more webs supporting the brake table. One end of each web is pivotally coupled to an associated brake spider and another end of each web responds to a force applied by an actuator that causes the brake shoe to move between positions of engagement and disengagement with an associated braking surface. The brake shoe further includes means for damping movement of the brake shoe, during engagement of the brake shoe with the braking surface, for a natural frequency of the brake shoe having an order of at least two and a causing a bending modal shape of the brake shoe. In one embodiment, the damping means includes a damping plate disposed on one side of a web. A spring acts on a side of the plate opposite the web to urge the plate towards the web.
