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.

Claims

1. In a motor car having a car body and two rear wheels with axle ends, two rigid crank arms, each of said crank arms having an end connected with a separate axis end, two bearings carried by the car body and a torsion axle having ends mounted in said bearings, said crank arms having ends connected with said torsion axle adjacent said bearings, said bearings receiving rotary, bending and axial movements.

2. A motor car rear axle according to claim 1, wherein each crank arm has a flat surface portion fixed to said torsion axle.

3. A motor car rear axle according to claim 2, wherein the first-mentioned end of each crank arm has a bracket and a spring member connected with said bracket.

4. A motor car rear axle according to clAim 1, wherein said torsion axle has both ends bent toward the respective bearings, said crank arms being welded to said bent ends.

5. A motor car rear axle according to claim 1, wherein each crank arm is composed of two plates.

6. A motor car rear axle according to claim 4, wherein said ends of the crank arms are recessed, said bearings having bearing rings and semicircular welding joints connecting said bearing rings with said ends of the crank arms.

7. A motor car rear axle according to claim 1, wherein said bearings are located at a shorter distance from the travelling path of the car than said torsion axle.
