Patent ID: 7695054

Claim:
A suspension device for the spring-loaded suspension of a weight body of a vehicle body relative to a substructure of a vehicle chassis, the suspension device comprising: an absorber device arranged between the weight body and the substructure for absorbing shocks and vibrations; a Watt's linkage arrangement connecting the weight body and the substructure such that the weight body and the substructure are able to perform a limited relative motion, for reducing the degrees of freedom of motion of the weight body in relation to the substructure, said Watt's linkage arrangement including at least two Watt's linkages, wherein the directions of straight-line motion of said at least two Watt's linkages agree to provide a common direction of straight-line motion, wherein said Watt's linkages are arranged at spaced locations from one another along said common direction of straight-line motion, and wherein the planes of motion of said at least two Watt's linkages extend in parallel to one another, a distance between fulcrum points of two Watt's linkage arms of said two Watt's linkages being greater than a distance between lateral thrust struts of associated outer articulation points of said two Watt's linkages, the outer articulation points associated with said lateral thrust struts of said two Watt's linkages being located in pairs each on a pivot axis that is common to said two Watt's linkages.
