Abstract
Introduced is a compound crank axle having a flexurally stiff and torsionally soft cross member, on whose ends two trailing links are arranged. The respective ends of the cross member are joined with the trailing links through friction welding in an angularly stiff manner. Here, the trailing links joined with the cross member are held together at a common transition region which is created in that both trailing links are joined together simultaneously and evenly with the cross member in a materially connected manner through friction welding.

A compound crank axle, comprising:
- a flexurally stiff and torsionally soft cross member;
- two trailing links arranged on ends of the flexurally stiff and torsionally soft cross member,
- wherein the ends of the flexurally stiff and torsionally soft cross member are joined with the two trailing links through friction welding in an angularly stiff manner.
A method for manufacturing a compound crank axle, comprising the steps of:
- providing a flexurally stiff and torsionally soft cross member;
- arranging two trailing links on ends of the flexurally stiff and torsionally soft cross member;
- and
- friction welding the ends of the flexurally stiff and torsionally soft cross member to the two trailing links in an angularly stiff manner.
