Abstract:
A suspension of a vehicle wheel on a vehicle body, with a spring strut device for the accommodation of compressive forces acting between the vehicle wheel and the vehicle body and connected as a linear actuator between said vehicle wheel and said vehicle body for adjusting the distance between the vehicle wheel and the vehicle body, said spring strut device comprising at least one tubular contraction element including at least one pressure chamber in a casing, said casing being designed in such a way that a pressure increase in said pressure chamber widens the casing radially and shortens it axially, and a force deflection device, which converts the compressive forces occurring between the vehicle wheel and vehicle body into tensile forces, said force deflection device including two support elements designed to be displaceable one within the other in a spring-compression direction of the vehicle wheel with respect to the vehicle body, one support element having a first end connected to the vehicle wheel and the other support element having a first end connected to the vehicle body, and said at least one contraction element being arranged concentrically with the support elements and engaging, at its one end, a second end of one support element and, at its other end, a second end of the other support element so as to subject said contraction element to tensile forces for accommodating said compressive forces.
