A disc brake for a utility vehicle includes a brake caliper, designed as a sliding caliper and engaging over a brake disc, which is secured to a stationary brake carrier. Two brake pads, which are arranged in the brake caliper, can move inversely and have a respective pad carrier plate and a friction lining secured thereon, of which an action-side or application-side brake pad can be pressed against the brake disc by an application device via at least one brake piston. The brake pads are each accommodated in a pad housing of the stationary brake carrier, wherein the pad housing is formed by two opposing brake carrier horns and a longitudinal connector connecting the brake carrier horns. At least one of the brake pads is assigned a pad return device, with which the at least one brake pad can be returned after a brake-dependent shifting and releasing of the brake.

For a vehicle disc brake, a piston-side first friction pad is provided with at least one protrusion on a piston-contacting section that excludes the central axis line of the piston and the piston is provided with an engagement hole capable of engaging with the protrusion. Symmetric with the piston-side first friction pad with a brake disc therebetween, a reaction pawl-side second friction pad is provided with a protrusion. As a result, it is possible to provide a vehicle disc brake in which the first friction pad and the second friction pad are both made to have a protrusion, reducing the possibility of incorrect assembly, and the friction pads themselves are made to be used in common, facilitating product management.

A brake system for a piece of equipment includes a series of rotors and stators, and a first brake actuator including at least one first piston positioned within a first chamber such that pressurization of the first chamber causes the at least one first piston to operatively engage at least one of rotors or stators such that the rotors and stators are compressed together and thereby create braking torque, and may also include a second brake actuator including at least one spring operatively coupled to at least one second piston positioned within a second chamber such that depressurization of the second chamber causes the at least one second piston to operatively engage at least one of the rotors or stators such that the pluralities of rotors and stators are compressed together and thereby create braking torque.

A disc brake for utility vehicles includes a brake disc, a brake caliper spanning the brake disc, a brake carrier, and an application-side brake pad and a reaction-side brake pad, of which at least the application-side brake lining is accommodated in a lining slot of the brake carrier. The brake caliper houses a brake application device having a single pressure plunger arranged to exert a brake application force on the application-side brake lining via a pressure plate. The brake is configured with one or both of an operative plane of the pressure plate being offset in the direction of the exit side at a distance from a plane of symmetry of the disc brake, and a bevel on the exit side of at least the application-side brake lining.

A hydraulic brake includes: an inner pad and an outer pad located to sandwich a rotor configured to rotate with a wheel between the inner pad and the outer pad; a wheel cylinder including a cylinder body including a cylinder bore, a hydraulic pressure chamber formed in the cylinder body, and a first piston liquid-tightly and slidably fitted in the cylinder bore and configured to be moved by a hydraulic pressure in the hydraulic pressure chamber so as to press the inner pad against the rotor; and a drive member configured to be moved, by the hydraulic pressure in the hydraulic pressure chamber, in a direction opposite to a direction in which the first piston moves, so as to press the outer pad against the rotor. The cylinder body includes a fragile portion at a portion corresponding to the hydraulic pressure chamber.

A multilayer piston insulator may comprise a plurality of axially aligned disks of a disk stack comprising, a first disk, a second disk, and a third disk, wherein the second disk is coupled axially between the first disk and the third disk and comprises a different material than the third disk, and wherein the disk stack is configured to couple to a hydraulic piston.

An actuating device for a coupling/braking device is provided with at least one actuating piston that is axially slidable relative to a shaft and, in an actuating state, exerts an axially acting contact pressure on coupling/braking parts of the coupling/braking device. At least one control piston is provided that axially displaces the at least one actuating piston into the actuating position. A coating is provided in a contact region between the actuating piston and the control piston, wherein the coating is disposed at the actuating piston or at the control piston or at both the actuating piston and the control piston. The actuating piston can also be designed as a control piston that interacts immediately with the coupling/braking parts of the coupling/braking device.

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 brake lining includes friction structures, back boards fastened to respective the friction structures, a base plate supporting the friction structures. Each of the friction structures includes two adjacent friction portions with a groove formed in the front surface in between, and a thin portion with a smaller thickness than thicknesses of the friction portions, the thin portion located in a position corresponding to the groove. Each of the friction structures is supported by the base plate on two support points located in the two friction portions respectively. The thin portion has a constant length, the length being equal to a maximum width of the friction portions and satisfying a condition that L/D is equal to or greater than 1.1, where D denotes the length of the thin portion and L denotes a distance between the two support points located in the friction portions.

Disclosed is a friction set for a railway disk brake system for railway rolling stock including: a shoe holder including a receiving slideway; a friction shoe including a brake pad and a profiled shape configured for being slid into the receiving slideway, where the friction shoe includes a pneumatic conduit connecting a first space delimited by a first surface of the friction shoe to a second space delimited by a second opposite surface the friction shoe; a through hole arranged in the shoe holder and laid out so as to be facing the pneumatic conduit; and a pneumatic connector mounted on the shoe holder, pneumatically connected with the through hole, extending away from the friction shoe and rotationally mobile relative to the shoe holder, around an axis perpendicular to a main plane of the shoe holder.
