Rear axle i.e. torsion beam trailing arm axle, for motor car, has transverse strut and control arm projection elements molded into one another and connected with one another, where strut projection element is designed as tube element

摘要

The axle has a control arm (20) comprising a transverse strut projection element (30), and a transverse strut comprising a control arm projection element. The projection elements are firmly connected with one another. The transverse strut projection element is designed as a tube element or a pipe section and made of a material that is different from that of the control arm. The projection elements are molded into one another and made of steel alloy. An axial recess (31) and/or an extensive recess (32) are distributed over a peripheral part of the transverse strut projection element. An independent claim is also included for a method for manufacturing a rear axle for a motor car.
