Embodiment Construction

[0039] exist Figures 1 to 4 In , the entire bearing unit 1 with the guide tube 4 installed is shown. in side view figure 1 It is particularly clear in the upper front how the steering shaft 2 protrudes from the bearing unit 1 . as specifically from Figure 4 As can be seen in , the steering shaft 2 is mounted in a bearing with an outer bearing bush 7 fastened in the guide tube 4 . In a concrete aspect, a bearing with a bearing bush 7 and balls 11 is pressed into the guide tube. There is also a corresponding bearing at the other end of the guide tube, although it is in Figures 1 to 3 Not obvious in , but in Figure 4 is very obvious in the Figure 4 where it is shown in section directly through the ball.

[0040] In the actual bearing unit 1 there are fastening elements 5 for the functional components and, in particular, fastening elements 6 arranged on the central bearing for direct or indirect fastening to the chassis cross member. The box-shaped housing 3 is usual...

Abstract

The invention provides a guide tube for a steering shaft and a method for producing same. A guide tube (4) for the rotatable mounting of a steering spindle (2) of a motor vehicle is described, wherein the guide tube (4) is rolled cylindrically from a single sheet-metal section and is connected at an axial contact point (12), and wherein the guide tube (4) has elements (13-15) for the definably axially displaceable fastening in a bearing unit (1). The guide tube (4) is characterized in that the elements (13-15) are designed in the form of at least two beads (13) which are distributed over the circumference, run axially, are formed circumferentially on both sides by ribs (14, 15) expanding the cylinder circumference and are formed in the sheet-metal section. A production method for such a guide tube (4) is also described.

Description

technical field [0001] The invention relates to a guide tube for a steering shaft of a motor vehicle and to a particularly simple, fast, robust and preferred method for producing said guide shaft. Background technique [0002] Steering devices in motor vehicles are generally constructed such that a steering shaft is rotatably mounted in a bearing unit to which a steering wheel is fastened. In order to make the steering wheel adjustable in its height, the bearing unit can be fastened to the chassis in such a way that the steering shaft can be fixed in different positions. In this case there is usually a guide tube which accommodates the outer bearing bush for the bearing of the steering shaft. [0003] Such guide tubes are generally designed as cylindrical tubes, of the type generally known in particular eg from EP0502761. [0004] Such a guide tube can also be mounted axially displaceable in the bearing unit, so that the steering shaft can be changed to a certain extent wi...
