SCHWINGUNGS-TILGERSYSTEM

A suspension system, in particular for vehicles capable of cross-country travel, such as tractors or caterpillar vehicles, includes springs connected in series to support the mass to be sprung, in particular the body mass of the vehicle, a coupler mass disposed between said springs, and a locking device operable by a control means to release the coupler mass approximately at one of the oscillation reversal or dead points of the mass to be sprung, in particular the vehicle body mass and to lock it again approximately after half the oscillation of the coupler mass, the springs being designed as hydropneumatic or gas/liquid spring elements, the hydraulic components of which are in fluid connection, the coupler mass being constituted by the liquid column of the hydraulic connection and the locking device comprising a valve arrangement connected in the hydraulic connection to block or open the same.
