  • Patent number: 12384443
    Abstract: An adjustment device for vehicle steering columns has a steering shaft to which a steering element can be attached, and a drive unit for adjusting a length of the steering shaft. The steering shaft has at least two tubes, which engage into each other in a telescoping manner, can be moved relative to each other, and can in each case be driven by a drive unit. The two drive units are arranged next to each other in the region below the adjustment device. If the two tubes are inserted into each other, the adjustment device only has a short length, which is measured in the displacement direction of the tubes. Conversely, if the tubes are extended in a telescoping manner, a very large length adjustment range can be achieved despite the short length in the starting position.

  • Publication number: 20250121873
    Abstract: The disclosure relates to a steering unit for a steer-by-wire steering system of a motor vehicle, having a steering shaft which can be rotated by a driver, and a spindle drive which interacts with the steering shaft to limit a steering angle of the steering shaft, wherein the spindle drive has a spindle and a spindle nut screwed onto the spindle, wherein the spindle nut is displaceable with a movement component in the axial direction relative to the spindle when the spindle is rotated, wherein the spindle nut has a first spindle stop for tangentially striking against a first end stop fixed to the spindle, wherein the first end stop is formed integrally with the spindle. The number of components is thus reduced, and the structure of the steering unit is simplified, as a result of which the effort for production and assembly is reduced, and cost-effective production of the steering unit is made possible.

  • Publication number: 20240336295
    Abstract: A compact adjustment device for steering columns of vehicles has a length-adjustable steering shaft to which a steering element can be connected. It includes at least one drive unit for length adjustment of the steering shaft. The steering shaft has a guide tube which is non-displaceably connected to a holder and into which an axially displaceable inner tube projects. It is drive-connected to the drive unit and can be connected to the steering element. Only a single drive unit is required to adjust the length of the steering shaft. It is used to axially move the inner tube to change the length of the steering shaft. The steering element is attached to the inner tube and can then be adjusted to the most favorable driving position using the inner tube. Since only one drive unit is required for the length adjustment, the design effort of the adjustment device is limited.

  • Patent number: 9669861
    Abstract: The steering column adjusting device for vehicles, preferably commercial vehicles, has a basic unit, with respect to which an adjusting unit is adjustable. With the adjusting unit, a steering spindle can be adjusted. In its respective position, the adjusting unit can be clamped with respect to the basic unit with at least one clamping device. The clamping device is pivotably mounted on the adjusting unit.

  • Patent number: 6634250
    Abstract: A steering column damper for a power-driven vehicle comprises a jacket tube with a central longitudinal axis; a sliding tube displaceably guided in the jacket tube; a steering shaft, which is mounted for pivotability about the central longitudinal axis relative to the sliding tube and/or the jacket tube and guided through the jacket tube and the sliding tube; at least one working area, which is disposed between the jacket tube and the sliding tube and filled with a damping medium; at least one working-area-volume reduction unit, which is connected with the sliding tube, reducing the volume of the at least one working area upon insertion of the sliding tube into the jacket tube; at least one aperture which opens the at least one working area to ambience for discharge of the damping medium from the respective working area; a closing element for blocking the at least one aperture; and a triggering unit for controllable release of the respective closing element.
