Abstract: A spot-type disc brake with a housing comprising a housing bridge, with at least one housing leg having an actuating assembly comprising an actuator unit and a component movable along an axis of movement. At least one brake shoe is arranged at the component and is slidably supported on at least one support. The brake shoe is braced with the support against an abutment surface by means of a hold-down spring. The abutment surface of the hold-down spring is arranged non-parallel to the axis of movement. Thereby, not only a radial preloading force FR is produced, but also a force component Fx normal thereto, which assists the retracting movement of the brake shoe from the brake disc, thus improving the clearance behavior.

Abstract: A brake shoe for a brake system has a backplate with a friction lining attached thereto and provisions which are mounted in the region of the friction lining that have the purpose of sensing the wear. In order to sense the state of wear of the friction lining and/or in order to identify the brake shoe, a passive transponder is provided which communicates using a wireless transmission technology, preferably using RFID (radio frequency identification) technology.

Abstract: A compact disk storage device having an outer-rotor dc-brushless electric motor for directly driving a disk for recording and reproducing information, having an axially deep, tank-form flange and a stationary shaft, upon which the mounting annulus of the flange and a bearing assembly of the hub are axially displaced. The bearing assembly has the stationary shaft fixedly mounted centrally in the deepened flange via a support bush. The hub includes a cap for sealing an extremity of the bearing assembly and an inverted cup shape rotor providing magnetic shielding.

Abstract: The present invention discloses a brake lining which, in order to reduce and eliminate noises, has a sliding metal sheet in addition to the classical lining parts such as friction lining, lining support plate and damping plate. Further, the damping plate has bores which are filled with grease. The purpose of the grease is, primarily, to lubricate the surface directed to the sliding metal sheet and the damping plate so that both surfaces can slide on each other without friction.

Abstract: It is frequently important for the piston of a hydraulic piston-and-cylinder assembly, in particular the brake piston of a disc brake, which is slidably arranged within a cylinder bore to ensure a true-to-size mounting position of the piston inside the cylinder bore. Especially in the case of brake pistons of a disc brake, this determines the efficiency of provisions on the brake piston for reducing the occurrence of brake noises. According to the present invention, a key-type accommodation is provided on the piston which permits engagement by a matingly configured mounting means or mounting tool and, thus, renders possible the defined positioning of the piston within a cylinder bore.

Abstract: A fixed caliper brake wherein, the material rigidity is reduced at appropriate locations on the brake housing and of the brake linings in order to create partial systems at the brake which can vibrate in a damped manner. With respect to weight, these steps are undertaken extensively in a neutral manner and they reduce the vibrations of the entire brake assembly resulting in a reduction in braking noises.

Abstract: Dual circuit brake force control units are known in which the initial preloading force is changeable dependent on the vehicle load. The preloading force is distributed to the control pistons by means of a lever. Due to the tolerances and erosion of the individual elements, considerable differences in pressure in both brake circuits may occur. Therefore, according to the present invention a lever is provided which directly acts on both control pistons and which is rotatable around an axis parallel to the direction of displacement of the control pistons and additionally around the longitudinal axis of the lever. The lever is in interaction with its housing mount at one support point at least and at two support points at the most with the support point or support points being located at least approximately in the longitudinal axis of the lever.
