20130087957DEVICE FOR DAMPING THE VIBRATIONS IN A CRAWLER OR TRACKED VEHICLE - A device for damping vibrations acting upon a track vehicle is provided. Long torsion bar springs which so far have been used to absorb torsion are subdivided into a plurality of small torsion bar springs. The torsion bar springs are operationally interconnected via drive or transmission elements and accommodated outside the interior, thereby removing the need for installation space for the damping device at a right angle to and below the vehicle chassis, and reducing it to the lateral zone or inside a minor recess in the chassis, a so-called chassis recess.04-11-2013
