Abstract

A combined track conditioning unit includes a dispensing apparatus with an outflow opening integrated in the front region of the dispensing apparatus which is suitable for applying a gaseous drying medium to a rail. A gritting material outlet unit which is integrated in the rear region of the dispensing apparatus and is suitable for applying a gritting agent to the rail also forms part of the dispensing apparatus. A rail vehicle is also provided. Additionally, a method for increasing a coefficient of friction between a rail and a wheel of a rail vehicle with the aid of a track conditioning unit is provided.

First claim

The invention claimed is:

1. A combined track conditioning unit for a rail vehicle, the combined track conditioning unit comprising:
a combined dispensing apparatus having a front region, a rear region, at least one outlet opening disposed centrally relative to a transverse direction of the rail vehicle and two outlet openings disposed laterally relative to the transverse direction of the rail vehicle, said two laterally-disposed outlet openings disposed upstream of said at least one centrally-disposed outlet opening in a travel direction of the rail vehicle and all of said outlet openings having a location in said front region for applying a gaseous drying medium to a rail, and a gritting material outlet unit having a location in said rear region for applying a gritting material to the rail;
said at least one centrally disposed outflow opening being configured for drying when traveling straight ahead, and said at least one centrally-disposed outlet opening including a plurality of centrally disposed outflow openings disposed on a rotary plate for drying when traveling straight ahead;
said two laterally-disposed outlet openings and said at least one centrally-disposed outlet opening being simultaneously and separately operable in dependence on conditions of the rail;
said locations of said outflow opening and said gritting material outlet unit causing a portion of a track being traveled over to be initially dried, to then have the gritting material applied to it and to finally be traveled over by a wheel of the rail vehicle with an increased adhesion value between the wheel and the rail.

2. The combined track conditioning unit according to claim 1 , wherein said outflow opening and said gritting material outlet unit are integrated fixedly in said combined dispensing apparatus.

3. The combined track conditioning unit according to claim 1 , wherein said outflow opening and said gritting material outlet unit have an adjustable and fixable position and orientation in a test phase.

4. The combined track conditioning unit according to claim 1 , wherein said two laterally disposed outflow openings are configured for drying the rail when traveling around a bend.

5. The combined track conditioning unit according to claim 1 , wherein said at least one centrally disposed outflow opening has a slider with a plurality of outlets, said slider being displaceable in a transverse direction permitting a position of a drying jet to be displaceable in a transverse direction.

6. The combined track conditioning unit according to claim 1 , wherein said outflow openings for applying a gaseous drying medium are configured to apply compressed air as the gaseous drying medium to the rail.

7. The combined track conditioning unit according to claim 1 , wherein said combined dispensing apparatus is configured to be heated.

8. The combined track conditioning unit according to claim 1 , wherein said outlet openings dispense a reduced amount of drying medium upon operating said two laterally-disposed outlet openings separately from said at least one centrally-disposed outlet opening.

9. A rail vehicle, comprising:
a plurality of trucks; and
a combined track conditioning unit according to claim 1 disposed on one of said trucks in front of a wheel of said one truck.

10. A combined track conditioning unit for a rail vehicle, the combined track conditioning unit comprising:
a combined dispensing apparatus having a front region, a rear region, an outflow opening having a location in said front region for applying a gaseous drying medium to a rail, and a gritting material outlet unit having a location in said rear region for applying a gritting material to the rail;
said locations of said outflow opening and said gritting material outlet unit causing a portion of a track being traveled over to be initially dried, to then have the gritting material applied to it and to finally be traveled over by a wheel of the rail vehicle with an increased adhesion value between the wheel and the rail; and
said combined dispensing apparatus having a plurality of centrally disposed outflow openings disposed on a rotary plate for drying when traveling straight ahead.
