  • Patent number: 6102378
    Abstract: A spring device arrangement in particular for the area of railway vehicles, in particular for spring suspension between a bogie and coach body, in which a spring device is located between a supporting plate and a substructure includes two spring systems connected in parallel. Each spring system comprises three parallel springs, the spring being an air spring or hydropneumatic spring comprising a bellows of elastomer material which connects the supporting plate to the upper part of a spring-support piston, the springs of the spring system being interconnected in a pressure-equalizing manner by an overflow duct. The spring is disposed outside the spring and extends from the supporting plate to the substructure, and the spring is installed in the support piston of the spring, a force-transmitting pressure piston simultaneously being used.
