摘要： The invention relates to a device for adjusting the height of a vehicle body, having two components, which can be moved longitudinally relative to each other, and a movement thread, which is arranged between these components. The movement thread includes a partial thread which is designed as a spindle paired with a first component and a partial thread which is designed as a spindle nut paired with the other component. The partial threads are designed to be axially movable relative to each other by a rotational drive. The device also includes a locking device which bridges the movement thread in at least three longitudinal positions and which comprises an axially fixed locking ring that is arranged on the spindle in a rotatable manner and has locking cams distributed over the circumference and a shifting gate that is rigidly connected to the spindle nut in an axial manner, receives the locking cams, and includes locking stops, which are arranged at end positions of the at least three longitudinal positions and are distributed over the circumference, and switching ramps, which lie axially opposite the locking stops, are provided with slopes that decrease in the circumferential direction, and are arranged over the circumference. A movement of the locking cams towards the locking stops and towards the switching ramps in the shifting gate is provided by an axial movement of the spindle relative to the spindle nut, this displacement depending on a rotational direction of the rotational drive, and a selection of the locking stops is carried out by rotating the locking ring by the rotated locking cams resting against switching stops provided between the switching ramps. In order to shorten the switching paths and the switching times of the locking device, at least one switching ramp arranged between two locking stops is expanded relative to the remaining switching ramps in a direction of the locking stops.

摘要： A belt drive for driving a rotatably mounted object, includes a main part, at least two belt wheels, a device for generating a pretensioning force, and a continuously circulating belt which loops around the belt wheels. The first belt wheel is connected to or can be connected to a drive, and the second belt wheel is connected to or can be connected to the object. The invention is characterized in that the device has at least two rollers which are attached to opposite sides of a lever that is pivotally mounted on the main part, and each roller contacts a section of the belt, wherein the lever is acted upon by at least one spring element and can be moved relative to the main part.

摘要： A device for level adjustment for a motor vehicle includes a ball screw. The screw nut of the ball screw is driven by an electric motor. The spindle of the ball screw is displaceable with respect to a housing. The ball screw is supported with respect to the housing using two axial self-aligning bearings with a common pivot point such that the housing can pivot with respect to the spindle, thereby avoiding loads on the balls of the ball screw.

摘要： A device (1) for adjusting the height of a vehicle body, including a movement thread (4) which is arranged between vehicle body and a wheel carrier and shifts two components (2, 3) which are displaceable in relation to each other between an upper and a lower adjustment position, wherein the movement thread (4) is provided with two threaded parts which are rotatable relative to each other, are formed from a spindle (7) and a spindle nut (3) and are in operative engagement with each other. The one threaded part is accommodated on one component in a manner fixed axially and rotationally driven by a rotary drive (6), and the other threaded part is accommodated on the other component non-rotatably and in an axially displaceable manner. In order to protect the movement thread (4), in particular the operative engagement, against high mechanical loads, a switchable locking device (18) spanning the operative engagement of the threaded parts (A, B) of the movement thread (4) is provided.
