Track clearer having aerodynamic guide plates
View Patent ↗A device for removing obstacles from a travel path of a vehicle includes clearing blades being mutually aligned in the form of a wedge and each having a wedge tip end facing the other clearing blade and a free end facing away from the wedge tip end. A fastening device or fastener fastens the device to the vehicle and a device for reducing a pileup generated by the clearing blades reduces pressure fluctuations at the vehicle tip without the need for providing the clearing blades with passages, apertures, or the like. The device for reducing the pileup has at least one vertical guide plate disposed in the vicinity or region of the free end of a clearing blade so that an air stream generated by the clearing blade flows past the vertical guide plate.
1. A rail vehicle, comprising:
a chassis;
a vehicle body supported on said chassis and having side walls;
a device for removing obstacles from a travel path, said device including two clearing blades being mutually aligned in a wedge shape, each of said clearing blades having a respective wedge tip end facing the other clearing blade and a respective free end facing away from said wedge tip end;
a fastener fixedly connecting said device to the rail vehicle;
a device for reducing a pileup generated by said clearing blades, said device for reducing the pileup including:
at least one vertical guide plate disposed in a region of said free end of at least one of said clearing blades and causing an air stream generated by said at least one clearing blade to flow past said at least one vertical guide plate, and
at least one horizontal guide plate each fastening said at least one vertical guide plate to a respective one of said clearing blades.
2. The rail vehicle according to claim 1 , wherein each of said clearing blades has an uninterrupted surface and is free of inner orifices.
3. The rail vehicle according to claim 1 , wherein:
said wedge tip ends form a wedge tip;
said wedge shape forms an angle defining a bisecting line, said angle, in a top view, is spanned in front of said clearing blades relative to said wedge tip;
said wedge tip and said bisecting line are disposed in a plane; and
each of said vertical guide plates has a surface section aligned parallel to said plane.
4. The rail vehicle according to claim 1 , wherein said at least one vertical guide plate includes a plurality of vertical guide plates.
5. The rail vehicle according to claim 4 , wherein said wedge tip ends form a wedge tip, and each of said vertical guide plates has an inflow side facing said wedge tip and being sloped downwards or upwards in a direction of travel of the vehicle.
6. The rail vehicle according to claim 1 , wherein said wedge tip ends form a wedge tip, and said at least one vertical guide plate has an inflow side facing said wedge tip and being arched toward a respective one of said clearing blades.
