A disc brake, preferably a compressed air-actuated disc brake, in particular for a motor vehicle, has a brake application mechanism with a brake rotary lever, at least one spindle unit having a threaded rod screwed into a bridge, and a brake caliper. The caliper frames an edge region of a brake disc. The brake caliper has a brake application portion and a caliper back which are connected together via tie bars. The brake application mechanism with the brake rotary lever is received in the brake application portion of the brake caliper from an application face side of the brake disc. The brake application portion of the brake caliper has a first region, in which the application mechanism and a force transmission portion of the brake rotary lever are arranged, a second region, which is formed as a lever housing, and a lever portion for the brake rotary lever. A support wall with a bearing portion, which forms a pivot bearing with a brake rotary lever axis that runs parallel to the brake disc, for the brake rotary lever is arranged between the first region and the second region.

A disk brake is proposed for a vehicle, preferably a commercial vehicle, having a brake caliper, a brake application device, an adjusting device, a brake lever, and a mechanism which couples the brake lever to the drive element. The brake caliper engages over a brake disk and brake linings on both sides of the brake disk. The brake application device can be actuated by way of a force element, preferably a pneumatic force element. The adjusting device compensates for the brake lining and brake disk wear. The adjusting device is arranged on an adjusting axis which extends in the brake application direction, and is provided with a drive element which can be rotated about the adjusting axis.

A disc brake assembly is provided that includes a camshaft extending from a slack adjuster. A disc brake rotor and a brake caliper bridge having an outer plate and an inner plate are provided. A brake caliper carrier is provided with an outer brake pad contained by the brake caliper carrier and an inner brake pad contained by the brake caliper carrier. A cam carrier having two openings is provided along with a pusher plate having a first surface in contact with the cam and a second surface in contact with the inner brake pad. A first and a second slide pin each extend through an opening in the cam carrier and an opening in the pusher plate and an opening in the inner plate of the brake caliper bridge and into the brake caliper carrier. A cam is mounted onto the camshaft such that rotation of the camshaft will rotate the cam, and the brake caliper bridge inner plate having a surface in contact with the cam. The brake caliper bridge outer plate having a surface in contact with the outer brake pad, such that upon rotation of the camshaft and the cam, the pusher plate adjusts the axial position of the inner brake pad and the brake caliper bridge outer plate adjusts the axial position of the outer brake pad, actuating the brake.

A brake device including a guide receiving area for connecting to a bearing component, forming a brake device bearing moveable in the direction of a first straight line. The brake device has a brake caliper with a first frictional surface and a first actuation surface, a pressing part being linearly guided along the first straight line relative to the brake caliper. The pressing part has a second frictional surface and a second actuation surface, and the brake device has a spreading element which interacts with the first actuation surface and the second actuation surface. The rotation of the spreading element changes the minimum distance between the frictional surfaces. A movement damping part coupled to the spreading element is designed to damp a translational movement of the spreading element relative to the bearing component in the guide receiving area parallel to the first straight line.

A disk brake includes a wear sensor and an adjusting device having an adjusting element in the form of a pressure screw and/or a pressure sleeve. The adjusting element has a recess in which a reset device extends which is rotationally coupled to the adjusting element for resetting the adjusting device. The wear sensor lies at least partially in the recess.

A disc brake that includes a housing, a piston, and a manual adjuster apparatus. The piston may be mounted within the housing and may have a rotatable portion defining an axis of rotation. The manual adjuster apparatus may be drivingly connected to the rotatable portion and may have a first element and a universal joint drivingly connecting the first element to the rotatable portion such that the first element extends away from the rotatable portion at an angle that is oblique to the axis of rotation.

A bearing is described that has a first race on a lever side that is curved in a partially cylindrical manner. The bearing has a second race on a pressure piece side that is curved in a partially cylindrical manner. Rolling elements are present that roll on both the first and second races and are grouped together in a bearing cage. A radial projection, which is fixed in terms of rotation relative to the second race and forms a stop which limits the mobility of the bearing cage in one circumferential direction, is present. A pocket or opening, which is arranged in the first race or extends partially into the first race, is also present.
