A brake apparatus for a vehicle may include: a caliper part fixed to a vehicle body, and having a cylinder provided therein; a piston part movably installed in the cylinder, and brought into contact with or separated from a pad plate part according to a moving direction thereof; a shaft part configured to receive a driving force from a driving part, and reciprocate in a direction parallel to a longitudinal direction of the cylinder; a pressing part connected to the shaft part, and configured to press the piston part toward the pad plate part as the shaft part is moved to one side; and an angle adjusting part provided between the shaft part and the pressing part, and configured to vary an installation angle of the shaft part with respect to the pressing part.

Some pin elements may have a substantially circular cross section, forming a circumference-shaped edge. Other pin elements may have a substantially rhomboidal cross section, forming a symmetric rhombus-shaped edge with respect to a radial direction and a circumferential direction orthogonal to this radial direction. Yet other pin elements may have a substantially circular cross section, forming a circumference-shaped edge.

A brake apparatus for a vehicle may include: a torque member having a pair of brake pads installed therein and spaced apart from each other, and configured to surround a brake disk; a caliper configured to cover the torque member, and having a gravitational center adjuster configured to adjust the position of a gravitational center toward the brake disk; a pair of guide rods configured to connect the torque member and the caliper, such that the caliper is slidably coupled to the torque member; and an actuator mounted on the caliper.

An electromagnetically operable brake arrangement for decelerating a rotationally mounted shaft, includes a magnet, a coil, a spring element, an armature disk, a brake pad support, a damping plate and a friction disk, the damping plate being situated between the armature disk and the magnet; the damping plate having projections; each of the projections extending further in a radial direction than in a circumferential direction; in particular, the projections each jutting out axially; in particular, at least a subset of the projections being evenly spaced apart from each other in the circumferential direction.

The invention relates to a disc brake, comprising a brake carrier, a brake caliper, brake shoes, and an actuating piston. The brake carrier has at least one mounting point for mounting on a vehicle. The actuating piston is displaceably accommodated on the brake caliper and is actuatable for carrying out a service brake function of the disc brake. At least one further actuating piston is provided, which in the direction of its longitudinal axis is displaceably accommodated on the brake caliper. For carrying out the service brake function, the at least two actuating pistons are actuatable, and for carrying out a parking brake function, one of the actuating pistons is actuatable. The invention further relates to a disc brake system and a parking brake system.

A friction lining holding spring and the equipped component/assembly, specifically a motor vehicle disc brake lining, including the friction lining holding spring. The friction lining holding spring includes an offset knee piece of a U-spring leg, which branches off at an angle from a largely flat U base section, and wherein the largely flat base section has a fastening tab with a cup-shaped rim hole including a through-opening for the purpose of fixing on a backplate of the friction lining, wherein each knee piece has integrated gearing, which is in particular designed as an uneven brake piston insertion trajectory such that, when a brake piston is inserted, there is a predefined gearing reduction effect for the purpose of automatically influencing or modelling the necessary force requirement.

A caliper guide assembly having a guide pin, a guide bore, a cap, and a sensor arrangement. The guide bore is arranged to receive the guide pin. The cap may be secured to an open end of the guide bore proximate a free end of the guide pin. The sensor arrangement may include a first sensor component that is configured to provide an output indicative of relative axial displacement between a first sensor component and a second sensor component.

Various embodiments of the present disclosure are directed to measuring rims and methods for measuring a brake abrasion of a wheel brake having a measuring rim. In one embodiment, consistent with the present disclosure, a measuring rim is disclosed including a circumferential tire support surface connected on one side to an end wall and on an opposite side to a seal to form an outwardly closed inner space, and a rotary feed-through provided on a central region of the end wall, the rotary feed-through configured to supply a gaseous medium to the inner space of the measuring rim and remove it therefrom.

Method for producing a mechanically and preferably machined cast iron or grey cast iron surface, in particular on a brake disc, with increased wear and corrosion resistance, characterized in that said surface is subjected to a water jet treatment—usually according to the so-called fluid jet process, which is adjusted so that it completely or at least partially clears the cavities opened by the machining, which contain a graphite inclusion surrounded by the basic structure, so that in the latter case the level of the graphite inclusion lies below the outer surface of the basic structure surrounding the cavity, whereupon a diffusion layer is applied by nitrocarburizing and an oxide layer is applied on the diffusion layer.

A method for repairing damage on a non-friction surface of a carbon brake disc of an aircraft, includes: removal of a damaged region, cutting of a repair material, anti-oxidation modification of the repair material, bonding and curing, and high-temperature heat treatment. The anti-oxidation modification is performed on the repair material without affecting the mechanical properties of the repair material, which improves the anti-oxidation ability of the repair zone and avoids the preparation of an anti-oxidation coating. In this way, only the damage on the non-friction surface is repaired, and there is little effect on the mechanical properties, friction and wear properties and thermal conductivity of the carbon-carbon composite material.
