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: 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.

Abstract: A coupling element for fitting to a threaded spindle. The coupling element has a receiving portion which is formed integrally with a coupling portion. The receiving portion extends in a hollow-cylindrical manner along an axis having an axial receiving opening for receiving the threaded spindle, and the coupling portion is flattened transversely with respect to the axis relative to the receiving portion and has a connection means. In order to be able to produce a coupling element in a more efficient and flexible manner, the receiving portion and the coupling portion be formed from a continuous integral pipe portion, wherein the coupling portion has a pressing portion in which the pipe portion is plastically compressed flat transversely relative to the axis.

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 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: An adjustable steering column for a vehicle includes a casing tube configured to rotatably mount a steering spindle. A guide bracket is connectable to the motor vehicle and includes two side cheeks between which the casing tube is arranged. An electromechanical fixing device is provided, in a release position of which the casing tube adjustable relative to the guide bracket, and in the fixing position of which the position of the casing tube is fixed. The fixing device includes a clamping bolt extending through the side cheeks and which, during the opening and closing of the fixing device, is rotatable about its axis via an electric motor, and a stroke-generating mechanism and a support bearing. The side cheeks and the casing tube are arranged between the stroke-generating mechanism and the support bearing and the electric motor acts via a pivotably mounted lever on the clamping bolt.

Abstract: An adjustment drive for a motor-adjustable steering column for a motor vehicle, includes a spindle drive having a threaded spindle which engages in a spindle nut which, so as to be able to be driven in a rotating manner about the spindle axis relative to the threaded spindle, is coupled to the rotor shaft of a drive motor which has a rotor and a stator. In order to enable a compact design with minor complexity, the rotor shaft of the drive motor is configured as a hollow shaft which is disposed so as to be coaxial with the spindle axis and in which the threaded spindle is coaxially disposed.

Abstract: A vehicle steering column includes a support unit and by which an actuator unit is held in which a steering spindle is mounted to rotate about a longitudinal axis. An adjustment drive is disposed between the support unit and the actuator unit and by which the actuator unit is adjustable. The adjustment drive has a threaded spindle which engages in a spindle nut and has a spindle axis. The spindle nut and the spindle are drivable by a servomotor to rotate in a mutually relative manner. The servomotor has a motor shaft which is coupled to a drive gear which is rotatable about a drive axis and which operatively engages with an output gear which is rotatable about the spindle axis and is connected in a rotationally fixed manner to the spindle nut or the threaded spindle. The drive axis and the spindle axis are disposed mutually parallel.
