Definitions
- the invention relates to an adjustment device for steering columns of vehicles according to the preamble of claim 1.
- the steering element of a vehicle such as a steering wheel
- the length of the steering train of the adjusting device can be adjusted, at least. There is less and less space available for the installation of such adjustment devices, especially when such adjustment devices are to be installed in electric vehicles. However, the functions of the adjusting device should not be impaired.
- the object of the invention is to design the adjusting device of this type in such a way that it requires little installation space without impairing its function.
- the adjusting device according to the invention is characterized in that its two tubes interlock telescopically and can be pushed against one another. If the two tubes are pushed into one another, the adjusting device has only a short length, measured in the direction of displacement of the tubes. If, on the other hand, they are extended telescopically, a very large length adjustment range can be achieved despite the small length in the initial position.
- the two tubes are each connected by a drive unit moveable, so that the tubes can be continuously pushed against each other if required.
- the drive units are located in the area below the adjustment device and are arranged next to one another, as a result of which a very compact configuration of the adjustment device is achieved.
- the two adjusting units advantageously each have a threaded spindle that can be driven in rotation.
- a drive nut sits on each of the threaded spindles and is drive-connected to the respective pipe. By turning the threaded spindle, the drive nut is moved, whereby the pipe coupled to it is adjusted accordingly.
- the threaded spindles of the two drive units for the two pipes are parallel to one another.
- the adjusting device is advantageously provided with a jacket tube into which the two tubes can be moved.
- the casing tube protects the two tubes, ensuring that the tubes can be reliably moved over a long period of use.
- the outer tube is advantageously provided on its inner side with at least one axial guide for the inner tube.
- the axial guide ensures that the two tubes can be moved against each other without any problems.
- a steering shaft extends through the inner tube and can be rotatably supported by a bearing arrangement in the inner tube.
- the steering spindle and the inner tube are firmly connected to one another in the displacement direction via the bearing arrangement, so that when the inner tube is displaced, the steering spindle is also taken along.
- the steering spindle is part of the steering rod and carries the steering element at its end.
- the steering shaft advantageously protrudes axially beyond the inner tube within the outer tube. On this protruding part of the inner tube sits a stop device, which has at least one element ceremoniessele, which engages in the axial guide of the outer tube. In this way, the steering spindle together with the inner tube can be easily moved relative to the outer tube.
- the stop device is provided with a grooved sleeve seated on the steering spindle. It has a helically running groove into which the guide element engages with at least one gripping element.
- the engagement element is formed in an advantageous manner by rolling balls.
- the groove of the groove sleeve advantageously extends over an angular range of more than 360°.
- the outer tube is drive-connected to the inner tube via at least one crash element.
- the crash element is formed in an advantageous manner by a sheet metal strip that can be easily and inexpensively manufactured and mounted on the adjustment device.
- connection element which is connected to the drive nut of the adjustment unit for the outer tube.
- connection of the connecting element to the drive nut is advantageously carried out via at least one shearing element.
- the connection between the outer tube and the inner tube is broken by the shearing element being sheared off. It is particularly advantageous if the steering train can be adjusted not only in terms of its length but also in terms of its height. Then an optimal adjustment of the steering element to the seating position of the driver is guaranteed.
- an adjustment unit is provided, which is mounted on a bearing block about an axis lying transversely to the longitudinal adjustment direction of the steering spindle.
- the steering column can be swiveled up or down.
- a lever is pivotally mounted on the bearing block, which is in turn pivotally connected to the jacket tube.
- the steering train is swiveled up or down.
- the adjustment unit for adjusting the height of the steering train acts on the lever.
- the lever is pivoted in the desired direction by means of the adjustment unit in order to adjust the steering train up or down.
- This adjustment unit advantageously has a threaded spindle that can be driven in rotation, with which a drive nut that is coupled to the lever can be adjusted.
- the lever is thus pivoted in the desired direction via the drive nut.

- the guide system 11, 13 can be arranged at an angle with respect to the guide system 12, 14, for example by 90°.
- a Constant actuator 15 which has a parallel to the splined shaft 4 threaded spindle 16 on which a drive nut 17 is seated (Fig. 1). Depending on the direction of rotation of the threaded spindle 16, the drive nut 17 is moved along the threaded spindle 16.
- the drive nut 17 is firmly connected to the inner guide tube 8, which is moved relative to the outer guide tube 7 depending on the direction of movement of the drive nut 17 on the threaded spindle 16 in the respective direction.

- a drive nut 21 sits on it and is axially firmly connected to the outer guide tube 7 . With the drive nut 21, the outer guide tube 7 can be moved axially relative to the jacket tube 5.
- the guide tube 7 In the driving position of the mechanism, the guide tube 7 is not displaced by the length adjustment drive 19.
- the guide tube 7 is held in the driving position by the self-locking mechanism of the transmission 20, 21, which is advantageous for a crash function to be described later.
- the guide tube 7 In the driving position of the mechanism, the guide tube 7 is not displaced by the length adjustment drive 19.
- the guide tube 7 is held in the driving position by the self-locking mechanism of the transmission 20, 21, which is advantageous for a crash function to be described later.
- the end of the threaded spindle 20 facing away from the length adjustment drive 19 is rotatably mounted in a radial extension 22 of the jacket tube 5 (FIGS. 1, 2 and 6 to 11).
- the drive nut 21 protrudes in a manner to be described with a connecting part 36 Ver through an axial opening 23 in the jacket tube 5 (Fig. 10).
- the length adjustment drive 19 In contrast to the length adjustment drive 15, the length adjustment drive 19 is stationary, so that its position does not change when the length of the steering train 1 is adjusted with respect to the adjustment device.
- FIG. 11 shows the steering train 1 in its retracted position.
- the outer guide tube 7 is almost completely retracted into the jacket tube 5 by means of the length adjustment drive 19 .
