Abstract: An electric linear motion actuator is provided which can set the clearance during normal braking operation of an electric brake system. The linear motion actuator includes a load sensor for detecting the magnitude of the load with which a friction pad is pressed against the brake disk, a temperature sensor for compensating for the influence of temperature on the load sensor, and an electronic control unit. The electronic control unit is adapted to calculate a target rotational angle from the position of the electric motor corresponding to the magnitude of the load detected by the load sensor to the position of the electric motor where the clearance is at a predetermined value, and control the electric motor to rotate the electric motor by the target rotational angle.

Abstract: An automatic slack adjuster (1, 101, 201) for braking systems of automotive vehicles, in particular for drum brakes of commercial vehicles, includes a lever (3, 103, 203) configured to be operatively coupled to a push rod (117, 217) of a brake actuator, and to pivot about a rotational axis (R) when actuated by the push rod (117, 217), the rotational axis (R) having a predetermined fixed location relative to the vehicle. The stroke level of the slack adjuster (1, 101, 201) is moveable between a predetermined zero stroke position (7a, 107a, 207a) and a working stroke range (7b). The invention furthermore relates to a braking system (100) for an automotive vehicle and a wheelset (200) can include the slack adjuster. An electronic detection unit (98, 109, 209) determines the current stroke level of the automatic slack adjuster (1, 101, 201).
