Shearing force reducing support device

The supporting device has a carrier support (2) coupled with a chassis (1), a piston rod (3) movable relative to carrier support and coupled with the carrier support, and a supporting disk (4) coupled with the piston rod. The supporting device is designed such that it allows a movement of the supporting disk relative to the carrier support. The movement is directed perpendicular to longitudinal axis (L) of the piston rod. The supporting disk automatically retracts into basic position during the idle supporting device.
