A brake caliper (1, 1) for a vehicle brake, in particular a disc brake of a commercial vehicle, includes a pressure piece (110, 110), a thrust piece (120, 120) configured to move axially relative to the pressure piece (110, 110) in a thrust direction (A) to transmit a braking force and a guiding member (130a,b, 130a,b) configured to limit the movement of the thrust piece (120, 120) relative to the pressure piece (110, 110) in at least one direction orthogonal to the thrust direction (A). The brake caliper (1, 1) may further include a lever (140) pivotally supported between the thrust piece (120, 120) and the pressure piece (110, 110), wherein the guiding member (130a,b, 130a,b) is configured to limit the movement of the lever (140) relative to the pressure piece (110, 110) and/or the thrust piece (120, 120) in at least one direction orthogonal to the thrust direction (A).

A brake caliper for a vehicle brake is provided. The vehicle brake includes a pair of brake pads, configured to be coupled to the brake caliper, and a disc positioned between the brake pads. The brake caliper includes an adjuster unit mounted to the brake caliper. The adjuster unit includes a gearwheel configured to be rotary driven in a first direction, and an adjuster nut operatively coupled with the gearwheel and configured to be operatively coupled with one of the brake pads, such that a rotational movement of the gearwheel in the first direction is converted, by the adjuster nut, into an axial movement of the brake pad towards the disc. The gearwheel is mounted in the brake caliper such that the gearwheel is axially fixed relative to the brake caliper, while the adjuster nut and the gearwheel are in an axially slidable engagement with respect to one another.

The vehicular disc brake comprises a caliper bracket 3, a caliper body 6 attached to the caliper bracket 3, and friction pads 7, 7 disposed on both sides of a disc rotor 2, and the caliper body 6 comprises an action part 6a provided with cylinder holes 6f, 6g through which a large-diameter piston 10 and a small-diameter piston 11 are inserted, and a bridge part 6c extending across the outer periphery of the disc rotor 2. Thinned parts 6n, 6p are provided respectively in positions corresponding to the pistons 10, 11 in a disc-radially inner wall 6i of the bridge part 6c. The volume of the thinned part 6b corresponding to the large-diameter piston 10 on the disc turn-out side when the vehicle is moving forward is less than the volume of the thinned part 6p corresponding to the small-diameter piston 11 on the disc turn-in side.

A disc brake half-caliper includes at least one cylindrical recess formed in a central portion of the half-caliper, the at least one cylindrical recess configured to support a piston for movement in an axial direction, and a pair of bridge portions formed on opposite sides of the central portion. At least one of the bridge portions extends further in the axial direction toward a first side of the disc brake half caliper than the central portion, defines at least one through hole extending therethrough in the axial direction, and terminates on the first side at a flat surface perpendicular to the axial direction, and has at least one cavity formed in the flat surface with a bottom at which the at least one through hole opens.

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.

Disclosed is a caliper brake including a carrier on which a pair of pad plates composed of an inner pad plate and an outer pad plate is mounted to advance and retreat, and a caliper housing slidably mounted on the carrier and provided with a cylinder part in which a piston is installed to be advance and retreat by a braking hydraulic pressure, a finger part bent downward for pressing of the outer pad plates, and a body part connecting the cylinder part and the finger part.

An electromechanical brake system includes a linear motion mechanism configured to convert the rotation transmitted from the electric motor to a linear motion, thereby pressing a friction pad against a brake disk; a linear motion mechanism housing in which the linear motion mechanism is received as a single assembly with the components of the linear motion mechanism assembled together; and a caliper body shaped to extend across the outer periphery of the brake disk. The caliper body includes a claw portion axially supporting a friction pad; a housing-fixing plate which is arranged on the side of the linear motion mechanism housing opposite from the brake disk; and an outer shell portion through which the claw portion and the housing-fixing plate are coupled together.

A disc brake of a floating type includes: an inner pad and an outer pad located on opposite sides of a rotor; a pressing device that presses the inner pad and the outer pad against the rotor; and a housing holding the pressing device. The pressing device includes: a first pressing member movable toward the rotor; a second pressing member movable away from the rotor; and a frame held by the housing via engageable portions movably relative to the housing in a direction parallel with a rotation axis of the rotor. The engageable portions are spaced apart from each other in a circumferential direction of the rotor. The frame is moved with movement of the second pressing member to press the outer pad against the rotor. Each of the engageable portions has a labyrinth structure.

A brake carrier is provided for a disc brake having at least one brake pad, wherein the brake carrier includes: a wrap-around disc holder that wraps around a section of a brake disc of the disc brake in a frame-like manner; at least one brake pad slot in which the brake carrier guides the at least one brake pad, wherein the at least one pad slot is formed by carrier lugs, support surfaces and bridge struts on the wrap-around disc holder. The brake carrier is produced as a single piece using a shaping method and has a mold partition burr. The mold partition burr is arranged outside of the wrap-around disc holder.

Disc brake comprising a yoke, at least one first brake pad mounted so as to slide within the yoke, the first brake pad comprising a pad support and a friction material, a caliper comprising at least one piston mounted so as to slide within the caliper in such a way as to move the first brake pad in relation to the yoke, at least one actuator configured to move the piston axially, and a separators device inserted between the piston and the first brake pad forming an equaliser so as to distribute the thrust force exerted by the piston onto at least two zones of the first brake pad, at least partially distinct from the projection of the piston onto the first brake pad.
