Abstract
The invention relates to a height control mechanism for a rail vehicle comprising suspension units that are arranged between the body and the bogie of the rail vehicle and that each comprise a spring, a pneumatic or a hydraulic reciprocating piston element. In accordance with the invention, the reciprocating piston element is retracted so much in train operation that it does not bridge the spacing between the body and the bogie.
