is achieved by the spring. Lateral guidance and maintenance of the track and camber angle are provided by the split axle of the wheel drive. With this arrangement, stiff wheel guidance in all directions except the compression is easier to achieve in terms of construction. However, it is also possible to guide solely the compression vertically to the tire contact area using the oscillating lever, whilst defining all the other directions of movement with a suitable wheel suspension. The disadvantage of this design is the high construction cost, which also results in a high degree of failure.
The present invention provides a vehicle undercarriage of the type mentioned at the beginning, which on the one hand avoids the disadvantages described above and on the other hand makes use ofare invariant towards the plane through the contact points of the wheels on the contact surface.
It is advantageous that an embodiment of the instant invention also includes that all connections between the individual parts are made exclusively with welding joints, since it allows rational manufacturing, possibly even with the use of welding robots.
In an advantageous embodiment the torsion spring includes of two concentrically arranged hollow profiles, whereby at least one elastomer element is provided between the hollow profiles, preferably in the area of mounting of the oscillating lever. In a further advantageous embodiment, the torsion spring includes an outer torsion spring tube, an elastomer spring element and a torsion spring axis. These torsion springs provide a sufficient longitudinal stiffness in the direction of their axis of rotation and
