Abstract
A rail vehicle, in particular a locomotive, has at least one bogie with a bogie frame supported resiliently on sets of wheels, and a superstructure, which is supported resiliently on the at least one bogie and is mounted rotatably about a vertical axis, with a under frame. A removal device for removing snow and/or ice is arranged between the under frame and the bogie frame. The removal device has an inclined sliding surface which at least partially covers the bogie frame. Deposits of snow and/or ice both on the bogie frame and on the under frame of the superstructure can thereby be prevented or eliminated.
Claims
1. A rail vehicle, comprising: at least one bogie with a bogie frame supported resiliently on sets of wheels; a superstructure resiliently supported on said at least one bogie and mounted rotatably about a vertical axis, said superstructure having an under frame; a removal device for removing snow and/or ice, said removal device being arranged between said under frame and said bogie frame; said removal device having an inclined sliding surface disposed to at least partially cover said bogie frame; said removal device having an upwardly oriented breaker edge rigidly connected to said bogie frame and facing toward said under frame, said breaker edge causing an accumulation of snow and/or ice on said under frame to be broken up upon being penetrated by said breaker edge when said bogie frame together with said breaker edge move relative to said under frame.
2. The rail vehicle according to claim 1, being a locomotive.
3. The rail vehicle according to claim 1, wherein said sliding surface has two oppositely inclined partial surfaces running up to one another to form a peak.
4. The rail vehicle according to claim 3, wherein said removal device has an attachment interface for attachment means enabling said removal device to be attached to different widths of bogie frame.
5. The rail vehicle according to claim 4, wherein said removal device is an integrally formed one-piece sheet metal part formed with a rounded breaker edge and two gable-roof-shaped partial surfaces emerging from said breaker edge as a sliding surface, and wherein said attachment interface is formed by coplanar contact surfaces having elongated holes abutting said partial surfaces.
6. The rail vehicle according to claim 1, wherein said removal device has an attachment interface for attachment means enabling said removal device to be attached to different widths of bogie frame.

DESCRIPTION OF THE INVENTION
(8) A removal device 1 according to FIG. 1 to FIG. 3 for removing snow S and/or ice E according to FIG. 5 and FIG. 6 is arranged between a under frame 13 of a superstructure of a rail vehicle and a bogie frame 10 of a bogie of the rail vehicle. According to FIG. 4 the removal device 1 has an inclined sliding surface 3 which at least partially covers the bogie frame 10. For stability reasons and because of the ease of manufacture the removal device 1 is bent from a sheet metal part 2. The integral bent sheet metal part 2 has a two-part sliding surface 3 in the manner of a gable roof, wherein the first partial surface 4 is inclined in an opposing manner to a second partial surface 5. The partial surfaces 4 and 5 run up to one another to form a peak and are connected to one another by way of an upward pointing, rounded breaker edge 6. The two partial surfaces 4 and 5 form a peak angle , which is preferably acute and for example can be about 50. The partial surfaces 4 and 5 each merge downward into an angled first and second contact surface 7 and 8, each of which is oriented in a coplanar manner to the other. The contact surfaces 7 and 8 serve to connect the removal device 1 to the bogie frame 10. To this end the contact surfaces 7 and 8 have elongated holes 9, through which attachment means (not shown), for example screws, can pass. The length and positioning of the elongated holes 9 are designed such that the same removal device 1 can be mounted on different widths of bogie. The removal device 1 is a component independent of the bogie frame 10 and can be mounted onto or dismounted from the bogie at any time thanks to its attachment interface. The removal device 1 can thus firstly be retrofitted on existing rail vehicles and secondly if need be can be fitted in the winter months and removed again in the summer months. The elongated bore holes 9 for screw-fitting to the cantrail 12 are moreover arranged such that a single embodiment of the removal device 1 can be utilized for different bogie frames 10. Thus one variant can for example be utilized both on broad-gauge and on normal-gauge bogie. Additionally the advantage of the variable screwed connection is that in the event of damage the removal device 1 can be replaced at no great expense.
(9) According to FIG. 4 the removal device 1 is mounted on the cantrail 12 of a head cross-member 11 of the bogie frame 10 and covers the major part of its top side. The removal device 1 extends in the exemplary embodiment illustrated crossways to a longitudinal bogie axis. The plane surface of the cantrail 12, which would favor an accumulation of snow S and/or ice E, is covered according to FIG. 5 by the sloping sliding surface 3. The partial surfaces 4 and 5 mean the snow S slips down in a sliding movement G and falls off the bogie frame 10. If the bogie is compressed and/or pitched according to FIG. 5 and the result is a relative movement R between bogie frame 10 and under frame 13, then the removal device 1 participates in this and with its breaker edge 6 strikes the accumulation of snow S and/or ice E on the under frame 13 of the superstructure of the rail vehicle. As a result the ice E is broken up and is detached from the under frame 13. This means the removal device 1 prevents accumulations of snow S and/or ice E both on the bogie frame 10 and also on the under frame 13 of the superstructure.
