Torsion Crank Axle

Assignment

This construction appeared quite early as a simple axle construction for mid-range front-wheel drive vehicles. With the exception of the U-profile as the axle tube, it was not difficult to produce, only the welding seams had to always have the same quality. The axle was reasonably priced, but not very space saving.

Function

One could consider the torsion crank axle to be a rigid axle, indeed, it is an independent suspension. The U-profile that joins the two wheels with each other, allows each wheel to move independently. However, together with the internal torsion bar, it functions as a stabilizer. The two trailing arms and the diagonal brace guide the wheels and take up the braking forces. 03/11
