Embodiment Construction

[0035] In the various figures, like elements are always provided with the same reference numerals, and therefore also usually each element is named or mentioned only once.

[0036] figure 1 shows a schematic perspective view of the steering shaft 10 shown, which comprises an outer hollow shaft 20 and an inner hollow shaft 30 that are telescopic with respect to each other in the direction of the longitudinal axis, ie in the longitudinal direction indicated by the double-headed arrow .

[0037] At the free end facing away from the inner shaft 30 in the longitudinal direction, the outer hollow shaft 20 comprises a fork 21 forming part of a universal joint via which the steering shaft 10 is connected in a torque-transmitting manner to the steering train. Thus, at the free end facing away from the outer shaft 20 in the longitudinal direction, the inner hollow shaft 30 comprises a bifurcation 31 forming part of another universal joint through which the steering shaft 10 passes in a...

Abstract

The present invention relates to a steering shaft (10) for a motor vehicle, said steering shaft comprising: an outer shaft designed as a hollow shaft (20); an inner shaft (30) which is coaxially arranged in the hollow shaft (20), is telescopic relative to hollow shaft (20) in the direction of the longitudinal axis of the steering shaft (10), and which is torque-transmittingly connected to the hollow shaft (20) via at least one positively-locking element (40); and comprising a locking device having at least one stop element (70, 700) which is fitted to the end region, facing the inner shaft (30, 300), of the hollow shaft (20, 200) and which has a stop face (78, 780) that is arranged in the opening cross section of the hollow shaft (20, 200) and that faces the hollow shaft (20, 200) in the direction of the longitudinal axis. In order provide an improved steering shaft which comprises a simple and easily mountable locking device for preventing pulling-out, the stop element (70, 700) according to the invention has at least one connecting means (74, 75, 76, 740, 741 ) which can be secured from the inside to the inner lateral surface (23) of the outer hollow shaft (20, 200) in the opening cross section.

Description

technical field [0001] The invention relates to a steering shaft for a motor vehicle, comprising an outer shaft and an inner shaft, the outer shaft being configured as a hollow shaft, the inner shaft being coaxially arranged in the hollow shaft, capable of being positioned in the direction of the longitudinal axis of the steering shaft Telescopic with respect to the hollow shaft and connected to the hollow shaft in a torque-transmitting manner via at least one rigid locking element, the steering shaft also includes a fixing device having at least one stop element mounted to the On the end region of the hollow shaft facing the inner shaft, there is a stop surface which is arranged in the opening cross-section of the hollow shaft and faces the hollow shaft in the direction of the longitudinal axis. Background technique [0002] Telescopic steering shafts in motor vehicles make it possible to adjust the steering column, the position of the steering wheel can be set in the longi...
