Abstract

A torsion cross beam having a torsion cross beam profile in which the insert element is inserted into an end region of the torsion beam profile to form a closed cross-sectional space, wherein the insertion element is directed at the end of the longitudinal center of the torsion cross beam to form an abutment region of the torsion cross beam profile so as to fit the profile base of the torsion cross beam profile in the direction towards the end; at least in the abutment area of the torsion cross beam profile against the base of the profile, the profile base has a first cross-sectional space; the cross-section of the first cross-sectional space is curved and has a curvature greater than zero; the profile base has a curved cross-sectional space in the abutment region, and the torsion cross beam together with the insertion element form a substantially quadrilateral second cross-sectional space in the end region; and when viewed in the longitudinal direction, the torsion cross beam profile has a transition zone between the abutment region and the free end of the torsion cross beam.

Description

technical field

[0001] The invention relates to a single-wall torsion beam for a torsion beam axle according to the preamble of claim 1 . Background technique

[0002] EP 2 098 391 B1 discloses a torsion beam axle and a method for manufacturing a torsion beam axle in which the torsion beam of the generic type has a cross-section that varies over its length and an omega-shaped center and end part, the cross-section of the Ω-shaped center part is open and has an undercut, the cross-section of the end part is U-shaped and the end part is on the longitudinal tie rod side. Closing plates are inserted into the ends to form closed cross-sections in each section. This end serves as the connection interface with respect to the longitudinal tie rods of the torsion beam axle. Such torsion beams are complex to manufacture and can have partially unfavorable tension peaks when loaded according to regulations.
