A tooth driven over-torque protection mechanism for use in a slack adjuster or as an air disc brake clutch, includes a shaft, toothed gear, a clutch device, a first spring, and a second spring. The toothed gear is disposed on the shaft. The toothed gear has a first pinion teeth set that extends along a first direction and a second teeth set that extends along a second direction. The clutch device that is also disposed on the shaft and includes an upper cam and a lower cam. The first spring biases the toothed gear against the clutch device. The second spring biases the clutch device against the toothed gear. The upper cam has cam teeth that cooperate with the second teeth set of the toothed gear in a torque transmitting manner, such that a torque applied in a clockwise direction to the first pinion teeth is transmitted to the upper cam through the second teeth set, but torque applied in a counterclockwise direction is opposed by the first spring.

The present disclosure relates to a brake lining arrangement for a vehicle disc brake, comprising at least one brake lining carrier plate, at least one friction lining, and at least one restoring element. The friction lining is attached to the front surface of the at least one brake lining carrier plate. The at least one restoring element is fastened to the rear surface of the at least one brake lining carrier plate and may be coupled to a brake caliper of the vehicle disc brake. At least one restoring element has at least two spring portions. The at least one restoring element is configured such that the at least two spring portions of the at least one restoring element act on the brake caliper under pretensioning.

Provided is an electric braking device wherein a friction member is pressed, via a piston driven by an electric motor, against a rotary member that rotates integrally with a vehicle wheel, thus generating a braking force on the vehicle wheel. The electric braking device is provided with: a controller for controlling the electric motor; a rotation angle sensor for detecting a rotation angle of the electric motor; and a return mechanism for applying a return force to a piston in a direction away from the rotary member. Furthermore, the controller executes a proper/improper determination to determine whether the return mechanism is operating properly on the basis of a change in the rotation angle after conduction of electricity to the electric motor is stopped.

The present disclosure relates to a disc brake arrangement comprising, a brake carrier, at least one brake lining, and at least one positioning device. The brake carrier comprises a brake disc shaft, comprising at least one outer face which is a side remote from the brake disc shaft, comprising at least one inner face which is a side facing the brake disc shaft, and comprising guide grooves which run in each case from the outer face to the inner face, the direction thereof defining an actuating direction, and which are formed in each case from two opposing guide surfaces and a support surface connecting the guide surfaces. The at least one brake lining comprises a friction lining and a lining carrier which is displaceably mounted by guide ears in the guide grooves in the actuating direction. The at least one positioning device comprises a guide and comprises a clamping device, the brake lining and the brake carrier being coupled thereby so as to be displaceable relative to one another. The clamping device has at least one protruding, elastically-acting clamping element which, due to the elastic deformation in an operating configuration of the positioning device, brings about both a frictional connection between the clamping device and the guide, which permits a wear adjustment and generates a restoring force when an actuating force is applied to the positioning device. The disclosure further relates to a mounting method for mounting a positioning device in the disc brake arrangement.
