Problems solved by technology

[0002] With such a clamping device, the following problem arises: the actuating lever connected in a rotationally fixed manner to the clamping pin has to exert the force required to clamp the clamping jaw in case of movement in the closing direction
The disadvantage of this damping device is the complex structure and the use of fluid

Embodiment Construction

[0029] exist figure 1 with figure 2 As can be seen in , the steering column shown is fixed to the vehicle chassis, not shown, by means of a carrier 4 which also has two clamping jaws 2, 3 which can be fixed by means of The clamping device is clamped together. In this case, the steering column tube 1 is securely clamped, the steering column tube 1 rotatably supports a multi-part steering shaft 5 which can be moved telescopically apart in the longitudinal direction 8 and into Together. When opening the clamping device, the steering column tube 1 itself can also be pushed forwards and backwards in the longitudinal direction 8 . Furthermore, the steering column tube 1 can be moved up and down in the vertical direction 9 when the clamping device is opened. When the steering column tube 1 is firmly clamped between the clamping jaws 2 , 3 by means of the clamping device according to the invention, the steering column tube 1 cannot move in neither the longitudinal direction 8 nor...

Abstract

The invention relates to a clamping device of an adjustable steering column for motor vehicles, wherein a carrier (4) fixedly connected to the vehicle chassis is connected to two clamping jaws (2, 3)surrounding the steering column, between which clamping jaws a longitudinally and / or vertically adjustable jacket tube (1) of the steering column, which jacket tube rotatably supports a steering shaft(5), can be fixedly clamped, having a clamping bolt (6), which connects the two clamping jaws (2, 3) and which interacts with an application device (7), which is arranged on at least one of the two clamping jaws (2, 3), in such a way that, in the event of rotation of the clamping bolt (6) about the bolt axis (19) in the closing direction (14), the application device (7) clamps the jacket tube (1)between the two clamping jaws (2, 3) and, in the event of rotation in the opening direction (15), the application device releases the clamping jaws (2, 3) such that the jacket tube (1) can be adjusted. Said clamping device is improved with a view to a simple and especially economical design in that a damping body (11, 24) is arranged on the clamping bolt (6) and is frictionally or elastically connected to the clamping bolt (6) and that the damping body (11, 24) has a stop tongue (16), which radially protrudes from the clamping bolt (6) and, in the event of rotation of the clamping bolt (6) inthe opening direction (15), comes into contact with the jacket tube (1) or another part of the steering column and prevents rotation of the damping body (11, 24) such that the rotation of the clamping bolt (6) in the opening direction (15) occurs against the frictional force or elastic force and is damped.

Description

technical field [0001] The invention relates to a clamping device for an adjustable steering column of a motor vehicle, wherein a carrier firmly connected to the vehicle chassis is connected to two clamping jaws which surround the steering column and the steering column tube can Firmly clamped between the two jaws, the steering column tube can be adjusted longitudinally and / or vertically, and the steering column tube rotatably supports the steering shaft, the clamping device has a clamping pin, clamping The pin connects the two jaws, and the clamping pin cooperates with the clamping retaining means arranged on at least one of the two jaws such that in case of rotation of the clamping pin in the closing direction about the pin axis , the clamping and holding device clamps the steering column tube between the two clamping jaws, and when the clamping pin is rotated in the opening direction, the clamping and maintaining device releases the clamping jaws so that the steering column...
