Hydropneumatic spring element for rail vehicle has spring leg with hydraulic height regulating valve or height sensor for connection to control loop regulating or detecting piston position in cylinder

摘要

The device has a hydropneumatic spring leg for arrangement between a bogie and a railway vehicle wagon with a piston in a cylinder, each connected to one of the bogie or wagon. The cylinder's piston chamber is connected to a pressure storage device. The spring leg contains a hydraulic height regulating valve or a height sensor connected to/for connection to a control loop with which the piston position in the cylinder can be regulated or detected. The device has a hydropneumatic spring leg for arrangement between a bogie and a wagon of a railway vehicle with a piston (30) in a cylinder (40), each connected to one of the bogie or wagon. The piston chamber (42) of the cylinder is connected to a pressure storage device. The hydropneumatic spring leg contains a hydraulic height regulating valve or a height sensor (50) connected to/for connection to a control loop with which the piston position in the cylinder can be regulated or detected.
