ABSTRACT:
The invention relates to an electric power steering for a motor vehicle, that may include a gear rack (11) that is positioned axially displaceable inside a steering housing (1) and can be driven by an electric servomotor (16), arranged inside a motor housing (7), with the aid of a belt (14) and a gear (12) for assisting with the steering. A simple and reliable belt tensioning is possible by providing an insertion wedge (21) between the motor housing (7) and the steering housing (1), which pushes the motor housing (7) away from the steering housing (1) for the purpose of tensioning of the belt (14).
