An actuator assembly for a positively locking, switchable clutch or a brake includes a shaft that can be rotated with respect to a rotational axis and an actuator slide for actuating the freewheel. The actuator slide is rotationally connected to the shaft and can be moved relative to the shaft in the axial direction between a first position and a second position and an actuator, which is stationary at least in part, that moves the actuator slide between the first position and the second position. The actuator includes a stationary coil, which, in the energized state, generates a magnetic field, in which the actuator slide can be moved out of the first position into the second position or vice versa. The coil is not energized in the first and in the second position. The actuator fixes the actuator slide in the first position and the second position.

A disc brake including a brake caliper and a brake actuation mechanism having an amplification mechanism for introducing a clamping force, an adjustment mechanism for compensating a lining wear having a torque clutch, a thrust element for transmitting the clamping force onto the brake disc, wherein the thrust element includes an adjustment spindle, and a return mechanism, wherein the amplification mechanism, the adjustment mechanism, the thrust element and the return mechanism are mounted in a functional interacting manner in the brake caliper by way of a rod. The disc brake is further provided with at least one device, which is configured to exert a defined resistant torque on the rotation of the adjustment spindle.

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.

A wheel module according to an embodiment includes a wheel, a motor, a shaft, a holding member and a brake. A tire is mounted on the wheel. The motor is arranged on the inner side of the wheel and includes a stator and a rotor. The shaft is fixed to the rotor coaxially with a rotation axis of the rotor and transmits rotation force of the rotor to the wheel. The holding member holds the stator. The brake restricts rotation of the shaft. One end portion of the holding member in the axial direction of the rotation axis of the rotor is fixed to and supported by a support member. The brake is on the opposite side to the wheel with the support member interposed therebetween. The shaft extends to an inner portion of the brake while passing through through-holes formed in the one end portion and the supporting member.

A friction lining assembly having a backing plate and a sheet metal restoring spring fixed thereto, for a partially lined sliding-caliper type disk brake having a brake holder fixed with respect to the vehicle, on which friction lining assemblies arranged on both sides of a brake disk are slidably guided. A housing, which extends over the brake disk and the friction lining assemblies, is slidably mounted on the brake holder. The restoring spring is clamped axially between the brake holder and the friction lining assembly by at least one spring leg and applies a release clearance to the friction lining assembly. The spring leg extends over a hammer-head- shaped claw of the backing plate. The spring leg is plastically deformable in a defined manner under braking actuation as a result of a reduction in the friction-material thickness in order to impose a constantly dimensioned release clearance on the friction lining assembly.

A disc brake for a motor vehicle comprising a guide in which at least one brake pad assembly is guided such that it can move in a braking manner, wherein the brake pad assembly has a brake pad carrier on which a vehicle brake pad is attached which can be interacted with a brake disc in order to achieve a braking effect, wherein the brake pad carrier has at least one retaining tongue, wherein the guide has at least one receiving region and wherein the retaining tongue can be accommodated in the at least one receiving means by being guided in an actuation direction, wherein a reset device is in contact with the at least one retaining tongue, via which reset device a reset force acting against the actuation direction can be applied to same subsequent to an elastic deformation caused by braking deflection of the brake pad assembly, wherein the reset device has an elastically deformable region for resetting the brake pad carrier and a plastically deformable region or the permanent adaptation to a wearing of the vehicle brake pad. According to the invention, with this disc brake, the reset device can only be plastically deformed, as a result of a force acting thereon in the actuation direction along a guide surface of the receiving region, if the reset device has adopted a predetermined, exclusively elastic deformation as a result of this force, wherein the plastically deformable region is formed as a loop and is in direct contact with the retaining tongue and can also roll out along the guide surface during the plastic deformation.

A disc brake includes a caliper; a pad pressed against a disc by a movable portion of the caliper and including a mounting ear portion provided to be protruded in a longitudinal direction of the pad; a pad spring including a guide plate configured to guide the mounting ear portion, and a first biasing member configured to press the mounting ear portion of the pad toward outside of the disc; and a second biasing member provided at the pad to bias the pad in a direction away from the disc. The guide plate of the pad spring has a surface that abuts on the mounting ear portion of the pad pressed by the first biasing member. The pad spring includes a folded region protruded in an axial direction of the disc from the surface abutting on the mounting ear portion of the pad, and folded in a direction toward the outside of the disc and away from the mounting ear portion. The folded region includes an abutting portion which the second biasing member provided at the pad abuts on.

Methods and corresponding control devices for releasing an electric actuator in a reliable manner, such as an electric parking brake in particular, in a motor vehicle brake system. The aim of the invention is to provide an improved function and architecture which helps prevent the disadvantages of open-loop control systems when using a rationalized sensor system, thereby obviating closed-loop control systems. This is achieved by a release method and a corresponding electronic control unit which obtains an especially modulated change in the power requirement during the release process upon impacting the quasi-elastic release end stop of the electric actuating unit such that the change is fed back, the change being detected in order to be used as information for a power interruption or a termination of the power supply to the electric actuating unit.

A novel, particularly rationally designed, modular parking brake actuator for an electric drum brake system. An axle A1 from the motor, including a screw gear pinion coupled in a rotationally fixed manner, and an axle A2 of the spindle arrangement, including a screw gear which is coupled in a rotationally fixed manner to the drive nut, define under a deflection of 90 a single wheel gearbox stage of the parking brake actuator.
