Actuator for actuating e.g. service brake of motor vehicle, has drive element actuating end of wrap spring in rotation direction, so that wrap spring is removed from housing and output is rotated in rotation direction

摘要

The actuator (1) has a drive element (7) connected with a motor (3) in a force-fit manner, where the drive element actuates an end of a wrap spring (4) in a rotation direction such that the wrap spring is removed from a housing (2) of the actuator. The drive element enables rotation of an output (6) in the rotation direction and actuates another end of the wrap spring in another rotation direction, such that the wrap spring is removed from the housing and the output is rotated in the latter rotation direction.
