Abstract
An adjustment device for suspension means in wheel suspensions of motor vehicles, with the suspension means having a first spring, for example a bearing spring that is arranged between the assembly of the motor vehicle and wheel guide elements, and/or a second spring, for example a preloaded spring that is connected in parallel or in series, as well as an electrically-actuated actuator, by means of which a force adjustment between the motor vehicle assembly and the wheel guide elements is made possible. According to the invention, the electric actuator is provided with an integrated brake or lock that acts in a bistable manner in such a way that in the unpowered state, it can occupy an open or closed position, and can be switched by means of electric actuation from the open to the closed position and vice versa.
