Abstract A rear axle for motor cars has axle ends of both wheels which are fixed to separate rigid crank arms swingably mounted in the car body. The invention is particularly characterized in that the two crank arms are connected to the car body by a torsion axle between their axle ends and their bearings; each crank arm is mounted by a bearing in the car body receiving the rotary, bending and axial movements.
