Abstract:
A disc brake comprises a brake carrier, which is fastenable to the vehicle and is provided with bolts at the leading side and at the trailing side of the brake, which during braking take up the forces acting upon the brake linings. The relative dimensions and arrangements of the bolts and of the brake lining are such that, upon introduction of a brake force that is capable of decelerating the vehicle up to a maximum value in the region of 0.1 g, only tensile forces act upon the brake lining.

A disc brake comprises a brake carrier, which is fastenable to the vehicle and is provided with bolts at the leading side and at the trailing side of the brake, which during braking take up the forces acting upon the brake linings. The relative dimensions and arrangements of the bolts (16a, 16b) and of the brake lining are such that, upon introduction of a brake force that is capable of decelerating the vehicle up to a maximum value in the region of 0.1 g, only tensile forces act upon the brake lining.
Abstract:
A brake lining module (10) with electric warning device (12) for indicating excessive friction lining wear comprises a back plate (14), to which a friction lining (16) is fastened, wherein the back plate (14) has a radially situated, friction-lining-free region (18). Disposed close to the back plate (14) in the friction lining (16) is a bore (24), in which a plug (28) is provided, which comprises a head (34) and a shank (32) with a longitudinal groove (38), in which an electric conductor (30) passed through the head (34) is accommodated. Projecting up from the head (34) of the plug (28) is a protective shield (36), which is laterally offset relative to the longitudinal groove (38) and has an extension (46), which at a distance above the head (34) protrudes in the direction of the common center plane (40) of the shank (32) and of the longitudinal groove (38). To reduce the overall radial height and prevent damage to the electric conductor (30), the back plate (14) in the friction-lining-free region (18) has a recess (48) open towards its radial edge and the extension (46) extends from the protective shield (36) over the common center plane (40) of the shank (32) and of the longitudinal groove (38) up to at least approximately the opposite edge of the shank (32). The recess (48) and the bore (24) have center planes which are at least adjacent.
Abstract:
A bolt guiding device for a floating caliper disc brake, having at least one guide bolt that is supported in a brake carrier and mounted on a brake caliper, wherein the brake caliper is movably guided over the guide bolt in the axial direction thereof. The bolt guiding device comprises a slide bush, wherein one surface of the inner circumferential surface and outer circumferential surface acts as a retaining surface on which the slide bush is retained, and wherein the other surface of the inner circumferential surface and outer circumferential surface acts as a sliding surface on which the slide bush slides. For this purpose, the slide bush has, facing the sliding surface, at least one guiding surface on each side of the center of the slide bush and at least one intermediate surface extending in the circumferential direction on each side of the center of the slide bush, wherein the diameter of the at least one guiding surface is dimensioned in such a way that said guiding surface is in close contact with the sliding surface, and wherein the diameter of the intermediate surface is dimensioned in such a way that said intermediate surface is provided in direct contact with or with a slight radial spacing from the sliding surface.
Abstract:
Vehicle disk brake designed as a service brake and as a parking- or immobilizing brake, having a brake anchor plate, which is to be fastened to the chassis of a motor vehicle by at least one screw bolt and in which two guide bolts are accommodated in order to guide a brake caliper displaceably relative to the brake anchor plate, and having a hydraulic chamber, in which a brake piston is accommodated in order to bring friction linings into and out of frictional engagement with a brake disk. A separately manipulable assembly is built onto the vehicle disk brake and has an electric motor as well as an electronic control and power device in order, independently of a hydraulic actuation of the brake piston, to actuate the brake piston via a rotary-to-linear motion converter in the sense of bringing the friction linings into and out of engagement with the brake disk. In order to create the extra space required by the use of a smart actuator for the parking brake unit in the internal wheel contour of compact vehicles, modifications to existing and tried-and-tested components are undertaken, which simultaneously improve the accessibility for maintenance purposes.
Abstract:
A disc brake having a brake carrier (10) which may be fastened to the vehicle and to which bolts are fastened, comprises brake pads (32a, 32b), in the supporting plates of which U-shaped recesses (40, 40′) are formed, which are placed onto the bolts, such that the brake pads are axially movably guided relative to the brake disc.

Abstract:
A hydraulic vehicle brake (10) has a hydraulic chamber (16) which sealingly accommodates a brake piston (18) which can slide along an axis (A). The brake piston (18) acts upon a friction member and can be moved by means of hydraulic pressure which is supplied to the hydraulic chamber (16) into an actuating position in which it presses the friction member against a rotor (brake disk, brake drum, etc.). In order to be able to use the vehicle brake (10) besides its function as a hydraulic service brake also as a parking brake, a spindle/nut arrangement (24) is provided which is driven by an electric motor (42) and arranged coaxial to the axis (A) of the brake piston (18), the nut (30) of which arrangement (24) is secured against rotation, and by rotation of the spindle (26) as a function of the sense of rotation can either be moved into contact with the brake piston (18) or be moved away from the brake piston (18) translatorily along the axis (A). For realizing a compact and economical construction, the output shaft (46) of the electric motor (42) extends at a lateral distance parallel to axis (A) and exits the electric motor (42) at the side facing away from the brake piston (18). In addition, a reduction gear (44) with a reduction ratio in the order of 200:1 is connected between the electric motor (42) and the spindle (26), with the electric motor (42) and the reduction gear (44) being designed as a subassembly (40) which can be handled separately.
Abstract:
In a method for producing a brake carrier for a disc brake of a vehicle braking system, wherein the brake carrier has at least one guiding shaft for guiding a brake lining in a guiding direction in relation to a receiving region for a brake disc, first a brake carrier blank is produced in a casting step and then the brake carrier blank is reworked. In the casting step, the brake carrier blank forms two converging tapers, facing the receiving region, in the region in which the guiding shaft is formed and, during the reworking, material is removed in the region of the tapers to produce the at least one guiding shaft, with the effect that the receiving region for the brake disc has a predetermined clear width transversely in relation to the guiding direction.
