Abstract

An adjustment device for a track conditioning unit has a measuring unit for determining a lateral offset of a rail, travelled on by a rail vehicle, relative to an effective range of a track conditioning unit or a measuring unit for determining the relative position of a bogie with respect to the rail car body. The adjustment device contains a determining unit for determining an actuation command for an actuation unit in accordance with the determined lateral offset between the effective range of the track conditioning unit and the rail. Part of the adjustment device for the track conditioning unit is also an actuation unit for actuating an actuator unit of the track-conditioning unit with an adjustment command which is generated on the basis of the actuation command. The actuator unit adjusts an effective range of the track conditioning unit on the basis of the adjustment command.

First claim

The invention claimed is:

1. An adjustment installation for a track conditioning unit, the adjustment installation comprising:
at least one sensor providing signals for:
determining a relative transverse offset of a rail traveled by a rail vehicle in relation to an effective range of the track conditioning unit of the rail vehicle, or
determining a relative position of a bogie and of a car body of the rail vehicle;

a determination unit configured for determining an actuation command in dependence on:
the relative transverse offset determined between the effective range of the track conditioning unit and the rail, or
the relative position of the bogie in relation to the car body of the rail vehicle;

an actuator being actuated based on the actuation command;
said actuator configured for adjusting the effective range of the track conditioning unit based on the actuation command, said actuator configured for displacing the effective range of the adjustment installation for the track conditioning unit by opening one of a plurality of exit openings for an auxiliary media, wherein the one of the plurality of exit openings that is opened has an effective range that is most suitable for the relative transverse offset that was determined, wherein the rail vehicle has a wheel and the plurality of exit openings are located adjacent the wheel of the rail vehicle.

2. The adjustment installation for the track conditioning unit according to claim 1 , wherein said determination unit is configured for determining the actuation command in such a manner that an improved value of an effect increasing a coefficient of adhesion is achieved.

3. The adjustment installation for the track conditioning unit according to claim 1 , wherein said determination unit is configured for determining the actuation command in such a manner that an optimal value of an effect increasing a coefficient of adhesion is achieved.

4. The adjustment installation for the track conditioning unit according to claim 1 , wherein said determination unit is configured for determining the actuation command in such a manner that a predetermined minimum value of a size of an interface between the effective range and a rail face is achieved.

5. The adjustment installation for the track conditioning unit according to claim 4 , wherein said determination unit is configured for determining the actuation command in such a manner that a maximum interface between the effective range and the rail face is achieved.

6. The adjustment installation for the track conditioning unit according to claim 1 , wherein said at least one sensor includes:
at least one sensor configured for recording sensor data of the rail traveled by the rail vehicle and for determining the relative transverse offset based on the sensor data; or
at least one sensor configured for determining the relative position of the bogie in relation to the car body of the rail vehicle.

7. The adjustment installation for the track conditioning unit according to claim 6 , wherein a technical function of said at least one sensor unit is based on one of the following principles of measurement:
optical;
inductive;
ultrasonic; and
capacitive.

8. The adjustment installation for the track conditioning unit according to claim 1 , wherein said determination unit includes a switching logic having at least one suitable switching threshold value which indicates a departure from an optimal effective range on the rails, wherein the switching threshold value is based on a geometric configuration of the track conditioning unit and on a minimum size of the optimal effective range.

9. The adjustment installation for the track conditioning unit according to claim 1 , further comprising a mechanical transmission installation which is configured for converting a relative movement between the car body and the bogie of the rail vehicle to an adjusting movement for adjusting the effective range of the track conditioning unit.

10. A rail vehicle, comprising:
a track conditioning unit; and
an adjustment installation according to claim 1 , said adjustment installation for said track conditioning unit for adapting the effective range of said track conditioning unit to the relative transverse offset of rails traveled by the rail vehicle.

11. A method for adjusting a track conditioning unit of a rail vehicle, which comprises the steps of:
performing one of:
determining a relative transverse offset of a rail traveled by the rail vehicle in relation to an effective range of the track conditioning unit of the rail vehicle, or
determining a relative position of a bogie in relation to a car body of the rail vehicle;

determining an actuation command in dependence on the relative transverse offset or the relative position of the bogie in relation to the car body;
generating an adjustment command based on the actuation command;
adjusting an effective range of the track conditioning unit based on the adjustment command; and
displacing the effective range of the adjustment installation for the track conditioning unit by opening one of a plurality of exit openings for an auxiliary media, wherein the one of the plurality of exit openings that is opened has an effective range that is most suitable for the relative transverse offset that was determined, wherein the rail vehicle has a wheel and the plurality of exit openings are located adjacent the wheel of the rail vehicle.
