Embodiment Construction

[0095] In the different figures, the same components are always identified with the same reference numerals and are therefore usually also referenced or mentioned only once.

[0096] figure 1 Shown is a steering column 1 with a carrying unit 10 that can be connected to the chassis of a motor vehicle, which is not shown in this case, and along the longitudinal direction L and along the vertical direction H (as double Arrow) adjustably holds the adjustment unit 16 on the chassis. The carrier unit 10 comprises a console 100 which can be fastened to the chassis of a motor vehicle, for example by means of fastening holes 102 .

[0097] The adjustment unit 16 comprises a cover tube 12 in which a steering rod 14 is rotatably supported. At the end 141 of the steering rod 14 on the steering wheel side, a steering wheel, not shown in this case, can be fastened. The steering rod 14 is used to transmit a steering torque introduced by the driver via the steering wheel onto the steering ...

Abstract

The present invention relates to a coupling element (6) for attaching to a leadscrew (4), which coupling element has a receiving portion (61), which is formed as a single piece with a coupling portion(62), wherein the receiving portion (61) extends in the shape of a hollow cylinder along an axis (S), with an axial receiving opening for receiving the leadscrew (4), and the coupling portion (62) isflattened perpendicularly to the axis (S) relative to the receiving portion (61) and has a connecting means (63). In order to be able to produce a coupling element (6) more efficiently and more flexibly, according to the invention the receiving portion (61) and the coupling portion (62) are formed from a continuous, integral pipe piece, the coupling portion (62) having a pressed portion (62), inwhich the pipe piece is plastically squeezed flat perpendicularly to the axis (S).

Description

technical field [0001] The invention relates to a coupling element for fitting to a threaded rod, the coupling element having a housing part integrally formed with the coupling part, wherein the housing part extends along the axis in a hollow cylindrical manner, The receiving part has an axial receiving opening for receiving the threaded rod, and the coupling part is transversely flattened relative to the receiving part with respect to the axis and has connection means. The invention also relates to a threaded rod with such a coupling element, a rod drive with such a threaded rod, and a steering column for a motor vehicle with a rod drive, such as an adjusting drive. Background technique [0002] A steering column for a motor vehicle has a steering shaft with a steering rod, to the rear end of which a steering wheel for introducing steering commands from a driver is fitted in a direction of travel facing the driver. The steering rod is rotatably supported about its longitud...
