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 and 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, a steering column tube 1 is securely clamped, which rotatably bears a multi-part steering shaft 5 which can be moved apart in a telescopic manner 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 the vertical direc...

Abstract

A clamping device may include clamping jaws that selectively clamp a steering column tube that is adjustable. A clamping pin may connect the clamping jaws. Rotation of the clamping pin in a closure direction causes the steering column tube to be clamped between the clamping jaws, and rotation of the clamping pin in an opening direction releases the clamping jaws for adjustment of the steering column tube. A damping member may be disposed on the clamping pin and connected to the clamping pin in a frictionally engaging or resilient manner. The damping member may comprise a stop tongue that protrudes radially from the clamping pin. When the clamping pin rotates in the opening direction, the stop tongue moves into abutment with the steering column tube and prevents rotation of the damping member so that the rotation of the clamping pin in the opening direction occurs counter to the friction force or resilient 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...
