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.
Claims14
A height control mechanism for a rail vehicle comprising suspension units that are arranged between a body and a bogie of the rail vehicle and each comprise at least one spring and at least one pneumatic or hydraulic reciprocating piston element, wherein
- the reciprocating piston element extends to raise the body to a platform height which is greater than an operation height maintained by the at least one spring, and the reciprocating piston element retracts in train operation such that it does not bridge a spacing between the body and the bogie.
A method for adjusting a height control mechanism for a rail vehicle:
- the height control mechanism comprising:
- suspension units arranged between a body and a bogie of the rail vehicle and each suspension unit comprising at least one spring and at least one pneumatic or hydraulic reciprocating piston element,
- extending the reciprocating piston element to raise the body to a platform height, the platform height greater than an operation height, and
- after the rail vehicle leaves a platform, retracting the reciprocating piston element such that the reciprocating piston element does not bridge a spacing between the body and the bogie to lower the body to the operation height, and the operation height maintained by the at least one spring element.
