The invention relates to a backing plate (1) for a disc brake of a motor vehicle, comprising a front side (2) for holding a friction lining. The backing plate (1) has a back side (3), on which a holding device (4) is arranged. The holding device is designed to hold a spring element (5), which consists of a spring base (6) and two spring legs (7, 8) arranged at the ends of the spring base (6). The holding device (4) is integrally bonded to the backing plate (1). The invention further relates to a method for producing a backing plate (1).

A brake drum includes an outer drum, at least one layer of heat resistant adhesive, provided at least on the inner radial surface of the outer drum, and an inner drum provided inside the outer drum connected with the outer drum via the at least one adhesive layer.

The application relates to a brake pad assembly for a disk brake system and to a disk brake system. The proposed brake pad assembly for a disk brake system comprises a back plate having a front side for facing a brake disk of the disk brake system and a back side. The brake pad assembly further comprises a friction layer arranged at the front side of the back plate for contacting a friction surface the brake disk. The back plate comprises a back plate body having a recess on its back side. The back plate further comprises a layered structure that is received within the recess of the back plate body. The layered structure comprises a copper layer and a rubber layer. The rubber layer covers the copper layer.

A method of refurbishing a steel-shell brake drum that includes superheating a worn-out brake drum until the worn-out brake drum is glowing hot. The worn-out brake drum includes a steel shell and a worn-out, gray-iron layer bonded to an inside surface of the steel shell. The method further includes centrifugal casting additional molten iron to the gray-iron layer to increase the radial thickness of the gray-iron layer.

A shaft-hub connection includes a shaft with a feather key groove, a hollow shaft, and a feather key. The hollow shaft has an inner groove, and the feather key is plugged into the feather key groove and radially protrudes into the inner groove of the hollow shaft. The feather key groove is only partially filled by the feather key, and a sealing part is received in the feather key groove.

Friction block or layer made of an asbestos free friction material, the friction material including, as composing materials thereof, inorganic and/or organic and/or metallic fibers, at least a binder, at least a friction modifier or lubricant and at least a filler or abrasive, wherein the asbestos free friction material also contains, as an additional composing material or additive, an hydrophobic wax, preferably present from 0.5% to 5% in volume, the asbestos free friction material block or layer possessing a hydrophobicity, defined as the time of absorption within the friction material of a liquid drop formed by 20+/5 L of distilled water, of more than 60 minutes, so that the force to detach the friction block or layer from a metallic surface to which it has been made to stitch electrochemically is lower than 15 Nw.

An electromechanical brake for a motor vehicle. The electromechanical brake includes an electric motor, which rotationally drives a mechanical adjustment unit arranged in a brake caliper housing, so that, for applying a braking force, a brake actuator is displaceable in an axial direction of the brake caliper housing. A motor housing arranged radially on the brake caliper housing accommodates the electric motor, and a control device housing of a control device controlling the electric motor is arranged on the motor housing. The motor housing is formed from the brake caliper housing and the control device housing, and the brake caliper housing is manufactured by a primary-shaping or reshaping step. A motor housing edge formed by the brake caliper housing, between the brake caliper housing and the control device housing, is formed in such a way that a radial height of the motor housing edge increases in the axial direction.

A clutch device includes a pressure plate movable toward or away from a clutch center and rotatable with respect to the clutch center. The pressure plate includes a flange extending radially outward from an outer circumferential edge of a body, pressure-side fitting teeth projecting in a first direction from a front surface of the flange, holding input-side rotating plates and a portion of output-side rotating plates being arranged in a circumferential direction, a body-side recessed portion recessed in the first direction from a second direction-side surface of the body, and a flange-side recessed portion recessed in the first direction from a back surface of the flange. As seen in an axial direction of an output shaft, the flange-side recessed portion at least partially overlaps one of the pressure-side fitting teeth.

Method for producing a friction material, including the following steps in sequence: mixing an aluminosilicate source with an alkaline silicate solution to form a geopolymer, adding a friction mix to the geopolymer solution of the previous step to obtain a slurry, casting the slurry in a mold at temperature between room temperature and 120 C. and for between 5 min and 2 h and demolding to obtain a pad, attaching a backplate to the pad, curing for a time between X and Y hours at a temperature of between X and Y. The friction material obtained with the method is for the manufacture of friction layers/blocks for friction elements such as braking elements, including vehicle brake pads or blocks, and/or friction discs.
