System for the secondary suspension of a superstructure of a rail vehicle having a passive spring element

摘要

A secondary suspension for a rail vehicle includes a superstructure, a bogie and a steel spring arranged between the superstructure and the bogie. The steel spring ensures at least one raised traveling level for the superstructure when the rail vehicle is traveling. Further included is a tension cylinder. When the rail vehicle is stopped, the steel spring is compressed by the tension cylinder to adjust the superstructure to a lowered station platform level below the at least one traveling level.
