Problems solved by technology

[0005] The disadvantage of the described solution is the need to use a toothed section connecting the clamping bolt to the actuating lever, which requires installation space and additional work steps during manufacture and is therefore expensive
Another disadvantage is that the disclosed bolt is inserted through the through-hole of the rod and thus creates a component protrusion

Embodiment Construction

[0016] figure 1 The motor vehicle steering column shown has a housing tube 1 which can be clamped firmly between two clamping jaws 2 , 3 . Parts of the jaws 2, 3 are fastened to a carrier 4 of the steering column, which fixedly connects the steering column to the vehicle chassis. Arranged in a rotatable manner inside the housing tube 1 is a steering spindle 5, a part of which consists of at least two parts which can be telescopic one inside the other The state of displacement. Furthermore, the two jaws 2 , 3 are connected to each other by means of a clamping bolt 6 , which interacts with a fastening device 7 such that in the case of a rotation of the clamping bolt 6 the two jaws 2 , 3 face towards Move toward each other until they clamp the housing tube 1 of the steering column fixed between them. In the simplest case, the fastening means 7 can be a nut screwed onto the external thread of the clamping bolt 6 . However, it is preferred to use a fastening device with a ball ...

Abstract

The invention relates to a clamping device of an adjustable steering column for motor vehicles, in which a support (4) securely connected to the vehicle chassis is connected to two clamping jaws (2, 3) containing the steering column, between which an axially and/or vertically adjustable casing tube (1) of the steering column for receiving a steering spindle (5) can be securely clamped, comprisinga clamping bolt (6) connecting the two clamping jaws (2, 3) which interacts with an application means (7) arranged on at least one of the two clamping jaws (2, 3), in such a way that the two clampingjaws (2, 3) securely clamp the casing tube (1) during a rotation of the clamping bolt (6) in the application direction about the bolt axis (19), and the clamping jaws (2, 3) release the casing tube (1) for steering column adjustment during a rotation of the clamping bolt (6) counter to the application direction, and comprising an actuating lever (10) secured on one end (13) of the clamping bolt (6) for rotating the clamping bolt (6), wherein according to the invention, the clamping device is improved to achieve a small installation space without projections, in that the actuating lever (10) iswelded to the clamping bolt (6).

Description

technical field [0001] The invention relates to a clamping device for an adjustable steering column of a motor vehicle, in which clamping device a carrier fixedly connected to the chassis of the vehicle is connected to two jaws which enclose the steering column, and an axially adjustable and / or vertically adjustable housing tube of the steering column can be fixedly clamped between the two jaws, the housing tube receives the steering spindle, the clamping device has a clamp A tightening bolt that connects the two jaws and interacts with a fastening device arranged on at least one of the two jaws such that when the clamping bolt is rotated about the bolt axis in the tightening direction , the two clamping jaws are fixedly clamped in the housing tube, and such that when the clamping bolt is rotated against the tightening direction, the clamping jaws release the housing tube for adjustment of the steering column, and the clamping The device has an actuating rod fastened to one e...
