Title: JOINING CONNECTION, METHOD FOR PRODUCING THE SAME, AND A STEERING COLUMN FOR MOTOR VEHICLES COMPRISING SUCH A JOINING CONNECTION
Abstract:
The invention relates to a joining connection between a peripherally closed hollow profile (1) and an add-on piece (2) which is provided with a through-opening (5) and which is of a lesser strength. The invention also relates to a method for producing the connection and to a steering column comprising this joining connection. The aim of the invention is to non-detachably join a hollow profile and an add-on part having a rigidity which is less than that of the hollow profile in a manner which can be easily reproduced and which is reliable with regard to the process, and to be able to mount, in a manner which is reliable with regard to the process, a support (2) as an add-on part on an outer tube (1) of the steering column, said support having a rigidity which is less than that of the outer tube, while using a fewer number of parts and incurring fewer costs and being able to effect an exact reproducible positioning of both joining partners with regard to one another in the joining connection. To these ends, a recess (10) located at a distance from the faces (8, 9) of the add-on part is provided on the inside (7) of the through-opening. In addition, the add-on part is to be slid with the through-opening thereof onto the hollow profile and is to be jammed with the same in this sliding seat position a local widening of the hollow profile formed at the location of the recess by means of internal high-pressure deformation.
