Abstract

A rail vehicle has a vehicle body supported in a sprung fashion on bogies. A snow plow has two blade plates that run to a point and a plow blade arranged vertically adjustably behind the blade plates. A projecting portion of the plow blade that projects downwards beyond a lower edge of the blade plates is adjustable. The blade plates rest with their lower edge on a base plate which forms a cutting edge that protrudes from the lower edge in the direction of travel. The snow plow is attached to an under frame of the vehicle body such that the base plate maintains a safety distance from the travel rails. The safety distance is predefined by a maximum spring compression of the vehicle body. The protruding portion of the plow blade is set as a function of the safety distance and of a wear of the wheels of the bogies.

First claim

The invention claimed is:

1. A rail vehicle, comprising:
a vehicle body supported in sprung fashion on bogies having rail wheels with wheel tires configured to travel along running rails, said vehicle body having an underframe;
buffer elements arranged on a forward end of said underframe and configured for absorbing impact energy through elastic compression of a buffer spring along a first energy absorption path, and deformation elements connecting said buffer elements to said underframe and configured for absorbing impact energy through plastic deformation of a deformation structure along a second energy absorption path
a snow plow mounted to said underframe, said snow plow having:
two blade plates running to a point in a plow shape, said blade plates having a C-shaped profile and a lower edge, said snow plow being fastened to said underframe so that said point lies behind said first and second energy absorption paths in the direction of travel;
a plow blade mounted behind said blade plates in a direction of travel of the rail vehicle, said plow blade being vertically adjustable and projecting downward beyond a lower edge of said blade plates with an adjustable projecting portion;
a base plate forming a cutting edge that protrudes forward from said lower edge of said blade plates in the direction of travel, said blade plates resting with said lower edge on said base plate;

said snow plow being fastened to said underframe of said vehicle body so that said base plate of said snow plow maintains a safety distance from the running rails, the safety distance being predefined by a maximum spring compression of the vehicle body, and said adjustable projecting portion of said plow blade being set in dependence on the safety distance and on a wear of said wheel tires of said rail wheels of said bogies.

2. The rail vehicle according to claim 1 , wherein the rail vehicle is a locomotive and said snow plow is mounted to a forward end of said locomotive.

3. The rail vehicle according to claim 1 , which comprises a deflection web integrally formed on an upper edge of said blade plates and projecting in the direction of travel.

4. The rail vehicle according to claim 1 , which comprises a plurality of reinforcing ribs extending in the direction of travel and connecting said blade plates to a rear wall extending transversely to the direction of travel.

5. The rail vehicle according to claim 1 , comprising lifting positions arranged laterally on said underframe for a lifting device, wherein said blade plates of said snow plow enclose an oblique point angle so that lateral outer edges of said blade plates terminate behind said lifting positions in the direction of travel.

6. The rail vehicle according to claim 1 , comprising an antenna device arranged behind said snow plow, and a bracket arranged on a rear wall of said snow plow and disposed to cover said antenna device from above.

7. The rail vehicle according to claim 1 , comprising a coupling element arranged on a front of said underframe, and wherein said snow plow is formed with a recess in the region of said point, through which said coupling element is guided.
