Embodiment Construction

[0019] exist figure 1 A bogie free space ( 2 ) of a rail vehicle with a diaphragm ( 5 ) fastened to a fastening point ( 6 ) according to the invention is schematically shown in FIG. The membrane is here arranged transversely to the direction of travel of the rail vehicle and in particular covers the corner recess formed by the partition wall ( 3 ) and the cover plate of the bogie free space. The inclined arrangement of the membrane in combination with the hydrophobic coating on the outside of the membrane supports the sliding or falling of snow or ice that accumulates on the membrane. The interspace between the diaphragm and the bulkhead or cover plate of the bogie free space is equipped with a volume-variable shaped body (7).

[0020] exist figure 2 The bogie free space ( 2 ) of a rail vehicle according to the invention is schematically shown with a membrane ( 5 ) applied to the outer surface of a deformable three-dimensional body ( 7 ). In this exemplary embodiment, an o...

Abstract

The invention relates to a rail vehicle for a driving operation on track systems having a ballasted superstructure. The invention is to effectively prevent or at least significantly reduce an agglomeration of snow and ice in cavities of the vehicle underbody. To this end, the rail vehicle comprises at least one flexible membrane (5) in the region of the underbody, said membrane spanning over hollow spaces or supporting framework structures of the underbody of the rail vehicle that are open toward the track system. The membrane (5) can be stimulated as dynamic vibrate during the drive of rail vehicle because of the flexile implementation structure.

Description

technical field [0001] The invention relates to a rail vehicle for traveling on a rail system with a ballast line superstructure. Background technique [0002] The problem that often arises during the operation of such vehicles is that due to various effects individual gravels are pulled up and bounced up from the gravel bed during the passage of the rail vehicle, wherein such high kinetic energy gravel The impact may hit the floor area of ​​a passing rail vehicle and damage may be caused there. Damage to track infrastructure equipment such as track switchgear may likewise be caused. The process may be enhanced by such crushed stones (which re-knock into the rail bed and cause rolling up of several other crushed stones there) into a solid and self-retaining crushed stone ballast heap over a longer period of time . This phenomenon is correspondingly known in the technical field as ballast jumping, ballast throwing or ballast jumping. The problem of bouncing ballast ballas...
