Patent ID: 8899159

Claim:
A spring assembly for level controlled support of a wagon body on a running gear of a vehicle, in particular of a railway vehicle, comprising a spring device which comprises at least one spring unit and an actuator device which comprises at least one actuator unit, wherein the spring device takes up a first installation space, the actuator device takes up a second installation space, the spring device and the actuator device are connected to each other in a direction of action in a kinematically serial arrangement, the actuator device is designed for at least partially compensating for a change in length of the spring device in the direction of action by a displacement at an actuator component in the direction of action, the first installation space and the second installation space overlap each other in the direction of action in an overlapping region, the at least one spring unit and the at least one actuator unit are arranged so as to be nested in each other to produce the overlapping region, the actuator unit is connected by at least one coupling device to the spring device, the at least one coupling device comprises at least one joint device via which the actuator unit is connected to the spring device so as to be pivotable about at least one decoupling axis, and the at least one decoupling axis is arranged in a plane running transversely, in particular perpendicularly, to the direction of action.
