A disc brake for utility vehicles includes a brake disc, a first brake lining on a first side of the brake disc and a second brake lining on a second side of the brake disc opposite the first side. A spreading device is also provided which generates a force that moves the first and the second brake lining away from one another.

Disc brake, in particular for utility vehicles

A method () for detecting the clearance of a brake () of a motor vehicle, in particular a utility motor vehicle, includes the following steps: reading measurement signals of a wear sensor () disposed on the brake (), determining an output signal value that is representative of the non-actuated state of the brake from the measurement signals, determining an event signal value that is representative of the braking state of the brake from the measurement signals, and determining the clearance from the difference between the event signal value and the output signal value, wherein the measurement signals of the wear sensor are examined for the presence of a characteristic signal oscillation that arises as a result of bringing into contact the brake lining with the counterpart thereof that is to be braked. A controller () carries out the method on a brake ().

A disk brake includes a brake disk, a brake caliper, at least one application device lying within the brake caliper on one side of the brake disk, an axially movable device configured to move a brake pad axially toward the brake disk by way of at least one actuating spindle when the brake is actuated, and an adjustment mechanism configured to rotate the actuating spindle because of a rotational coupling acting in the direction of rotation. The adjustment mechanism comprises a thread device, which, at least in the case of rotation in a second direction of rotation opposite a direction of rotation, is configured to mesh with an external thread of the actuating spindle and is configured to screw the adjustment mechanism in relation to the actuating spindle.

A disk brake includes a brake disk, a brake caliper, at least one application device lying within the brake caliper on one side of the brake disk, an axially movable device configured to move a brake pad axially toward the brake disk, and an adjustment mechanism configured to be rotated about an rotation axis lying parallel to a rotation axis of the brake disk and which, in the case of rotation in a first direction of rotation bringing about adjustment, is configured to rotate the actuating spindle. The adjustment mechanism includes a thread device which, at least in a rotation in a second direction of rotation opposite the first direction of rotation, is configured to mesh with the external thread of the actuating spindle and to screw the adjustment mechanism in relation to the actuating spindle.

An adjusting unit for an automatic slack adjuster of a vehicle drum brake includes a housing (), a worm shaft () mounted in the housing () so as to be movable between two end positions along an axial travel (A), a control pinion () arranged on the worm shaft, a worm () arranged on the worm shaft, and a freewheel () for power transmission between the control pinion () and the worm () in a first direction of rotation and for slip between the control pinion () and the worm () in an opposite, second direction of rotation. The worm shaft () has a first stop surface () and a second stop surface (), which can each be brought into contact with a corresponding first stop () and second stop () at the end positions of the housing (). An automatic slack adjuster includes such an adjusting unit.

The invention relates to a disk brake, in particular for utility vehicles, having a brake application shaft and having an adjusting device for wear-dependent adjustment, wherein a rotational axis of the brake application shaft is perpendicular to a rotational axis of the adjusting device and a pin serves to couple the brake application shaft to the adjusting device. A longitudinal axis of the pin encloses an acute angle with the rotational axis of the brake application shaft. The invention also relates to an adjusting device for a disk brake, in particular for utility vehicles, having an adjusting element in the form of an adjusting nut or an adjusting screw, and having a slipping clutch for limiting the torque which can be transmitted to the adjusting element. The slipping clutch has a friction element which is rotationally coupled to the adjusting element in both rotational directions.

The invention relates to a disk brake, particularly for commercial vehicles, comprising a hold-down spring () for holding down a force transmission device of the disk brake, wherein the hold-down spring comprises a first holding region () having a first support device for support on a hold-down device in the one circumferential direction of the brake disk of the disk brake and having a second support device for support on the hold-down device in the other circumferential direction of the brake disk. The hold-down spring comprises a second holding region () having a third support device for support on a hold-down device in the one circumferential direction of the brake disk and having a fourth support device for support on the hold-down device in the other circumferential direction of the brake disk. The first holding region is located symmetrically to the second holding region in regards to an axis of symmetry of the hold-down spring that is provided transversally to the longitudinal extension of the hold-down spring.
