JOINING CONNECTION, METHOD FOR PRODUCING THE SAME, AND A STEERING COLUMN FOR MOTOR VEHICLES COMPRISING SUCH A JOINING CONNECTION |
摘要 |
A joining connection between a circumferentially closed hollow profile and an add-on part which is provided with a passage opening and consists of a material of lower strength than the material of the hollow profile is disclosed. Additionally, a method for producing the connection and to a steering column having this joining connection is disclosed. In order to connect a hollow profile and an add-on part having lower strength than the hollow profile non-releasably to each other in a simple, reproducible and reliable manner, and furthermore in order to reliably fit a holder as an add-on part to the casing tube of the steering column, where the holder has a lower strength than the casing tube, with a low outlay on components and costs and with exact, reproducible positioning of the two joining partners with respect to each other in the joining connection, a recess is provided which is spaced away from the end sides of the add-on part on the inside of the passage opening, to slide the add-on part with its passage opening onto the hollow profile and to jam it to the hollow profile in this sliding-fit position by a local expansion of the hollow profile. The expansion being formed by internal high-pressure deformation at the location of the recess. |
