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.

Abstract: The disclosure relates to a steering assembly for a drive-by-wire steering system of a vehicle having an input means for inputting a steering command, a steering shaft with a first region and a second region longitudinally spaced apart from the first region, and a sensor system for detecting a steering angle and/or a steering torque on the steering shaft. The sensor system comprises a first angular-position sensor and a second angular-position sensor. The first angular-position sensor is assigned to the first region and the second angular position sensor is assigned to the second region, so that it is possible to determine, by means of a difference of a first angle signal of the first angular-position sensor and a second angle signal of the second angular-position sensor, the steering torque on the steering shaft on which the steering torque is acting.

Abstract: In a method for manufacturing a hollow wheel which includes an internal toothing and an external toothing, wherein the internal toothing is a gear toothing, a workpiece is machined by way of a stamping tool. The workpiece has a tubular section with a longitudinal axis and a first stabilisation section for the shape stabilisation of the tubular section during the machining. The tubular section is inserted into a die having an internal die toothing. The workpiece is machined on the inner side by the stamping tool so as to simultaneously produce internal and external toothing by way of the workpiece executing a rotation movement with a temporally varying rotation speed and the stamping tool executing radially oscillating movements that are synchronised with the rotation movement.

Abstract: A method for manufacturing a hollow wheel equipped with an internal gear toothing, wherein a work-piece includes a tubular section with a longitudinal axis, by which the term radial utilized in the following is defined. By N?2 stamping tools, of which each one during the implementation of the method is brought into a working position, the tool for producing the gear toothing is processed on the inside of the tubular section, wherein the work-piece carries out a rotating movement with a rotation speed varying in time around the mentioned longitudinal axis and at least one stamping tool in the working position carries out radially oscillating movements, which are synchronized with the mentioned rotating movement. The at least one stamping tool in the working position processes the work-piece repeatedly.
