Abstract: A motor adjustment drive for a vehicle steering column includes a threaded spindle with an axis. The threaded spindle engages a spindle nut. A drive unit and a gear wheel which is connected to the spindle nut or the threaded spindle for rotation therewith is driveable to rotate by the drive unit and is rotatably mounted in a bearing housing between two outer bearing rings that are axially supported at the bearing housing. The outer bearing rings each have, on their sides facing one another, a circumferential outer bearing face that is coaxial to the axis. Each outer bearing face lays opposite a bearing face embodied on the end side at the gear wheel. An outer bearing ring is axially resiliently supported at the bearing housing via an elastic element, which exerts an axial force that biases the two outer bearing rings toward each other.

Abstract: An adjustment drive for a motor-adjustable steering column for a motor vehicle includes a drive unit having a transmission in which there is mounted a drive wheel. The drive wheel can be driven to rotate about a drive axis and is in operative engagement with a transmission wheel which is mounted in the transmission so as to be rotatable about a transmission axis. The transmission has a drive module, which includes the drive wheel, and a transmission module, which includes the transmission wheel. The drive module and the transmission are connected to one another by a joining connection.

Abstract: A steering system for motor vehicles, including a steering actuator which acts on the steered wheels, is electronically controlled based on a steering request and acts on the steered wheels via a steering gear, and an actuator device which transmits reactions to a steering shaft connected to the steering wheel. The steer-by-wire steering system has a holding brake which can be activated electrically and has two positions; a holding position and an open position. The holding brake is configured to block rotation of the steering shaft in the holding position when a predefined rotational angle of the steering shaft is exceeded, and to release rotation of the steering shaft in the open position.

Abstract: An adjusting drive for a steering column for a motor vehicle may include a threaded spindle that by way of an external thread engages in a spindle nut. The adjusting drive may also include a drive motor that is coupled to the threaded spindle or the spindle nut such that driving at least one of the threaded spindle or the spindle nut with the drive motor causes the threaded spindle and the spindle nut to rotate relative to one another. To reduce production complexity and improve functionality, the threaded spindle may have a core element that at least in portions is coaxially surrounded in a fixed manner by a threaded element that is configured from plastic and comprises the external thread.

Abstract: A gear wheel for an adjustment drive mechanism which has a ring gear which is attached coaxially circumferentially to the outside of a core element which has an axial passage opening, in which a threaded element is fitted, the latter having an axially continuous internal thread having at least one thread tooth running around helically. The threaded element is formed from a plastic as an injection molded plastic part, which is molded onto the core element on an inner wall of the passage opening.

Abstract: A steering apparatus for a two-track vehicle may include a steering handle, in the case of whose rotary actuation the steerable vehicle wheels can be turned by a wheel steering angle, and a control device to electrically actuate a steering actuator for setting the wheel steering angle was a function of driving operational parameters and independently of the steering handle and a clutch that provides a releasable mechanical steering connection between the steering handle and the steerable vehicle wheels. An automatic avoidance manoeuvre may be carried out in the case of a risk of collision, in which the control device fully releases the clutch, and the control device actuates the steering actuator such that the vehicle briefly leaves its driving lane and is then brought back into the driving lane. The control device also actuates a braking of the steering handle during the collision avoidance manoeuvre.

Abstract: A steering column is disclosed for a motor vehicle, including an actuating unit, in which a steering spindle is rotatably mounted about a longitudinal axis. The actuating unit includes a casing unit which has at least three casing tubes which are arranged so as to be axially telescopable relative to one another. One of the casing tubes forms an outer casing tube in which at least one intermediate casing tube, in which an inner casing tube is accommodated, is accommodated. Rolling bodies are arranged between the casing tubes such that they are able to roll in the axial direction. First rolling bodies are arranged between the outer casing tube and the intermediate casing tube, and second rolling bodies are arranged between the intermediate casing tube and the inner casing tube, the first rolling bodies being arranged offset in the circumferential direction relative to the second rolling bodies.

Abstract: A motor-adjustable steering column for a vehicle includes a supporting unit attachable to a vehicle body and by which there is held an adjusting unit in which a steering spindle is mounted so as to be rotatable about a longitudinal axis. An adjustment drive is connected to the supporting unit and to the adjusting unit and is adjustable relative to the supporting unit. The adjustment drive includes a drive unit and a threaded spindle which engages in a spindle nut and which has a threaded spindle axis. The threaded spindle and the spindle nut can be driven to rotate relative to one another about the threaded spindle axis by the drive unit. To prevent slipping or spinning of the spindle drive in a crash situation the adjustment drive includes a blocking device which can be brought into a blocking position for blocking the threaded spindle relative to the spindle nut.
