摘要

A hydropneumatic spring element for vehicles, particularly track-laying vehicles, as well as a wheel suspension on a tracked vehicle with such a spring element. The spring element has a first cylinder (1), which a hydraulic damping member (6) as well as a first section (4) of an oil chamber and a part of an oil storage chamber (7) contains. In a parallel to the first cylinder (1) arranged second cylinder (1 ') are a second section (4') of the oil chamber, the separating piston (5) and the gas chamber (3) is arranged. The first cylinder (1) is connected to the second cylinder (1 ') via a connecting element (10), which a hydraulic connection (10.1) between the first section (4) and the second section (4') of the oil chamber contains. In the first cylinder (1) is a third cylinder (2) sealingly guided telescopically, and the remaining part of the oil storage chamber (7) contains. By means of a displacement of the first cylinder (1) and the third cylinder (2) with respect to each other is the capacity of the oil storage chamber (7) can be changed. As a result of this arrangement, it is possible to achieve a strong reduction of the structural length of the spring element, so that it can also be used for a small installation space on the impeller can be used to mount a ketttenfahrzeugs.
