Abstract

A suspension device is provided for the spring-loaded suspension of a weight body (3) relative to a substructure (1) such as a vehicle body, a cab (3) of a truck relative to the vehicle chassis (1). The suspension device has a spring/absorber device (2) arranged between the weight body (3) and the substructure (1) for absorbing shocks and vibrations. The suspension device includes at least one Watt's linkage arrangement (6) connecting the weight body and the substructure for reducing the degrees of freedom of motion of the weight body (3). The suspension device requires little maintenance and has little clearance and is suitable for setting the degrees of freedom of motion of the weight body as well as for absorbing and preventing the undesired motions of the weight body along other directions in space. The suspension device thus makes possible an inexpensive and reliably operating suspension especially of truck cabs.
