Abstract

The invention relates to a rail vehicle brake system comprising a conditioning device, having at least one disc brake per axle, the conditioning device having a control device. The conditioning device is formed having at least one wagon control unit and at least one coupling unit for selective actuation of the at least one disc brake per axle. The invention further relates to a conditioning device and to a method for operating a conditioning device, and to a method for deicing and/or for preventing icing of a brake unit of a rail vehicle brake system.

First claim

The invention claimed is:

1. A rail vehicle brake system, for a high-speed rail vehicle, the system comprising:
a conditioning device; and
at least one disc brake per axle,
wherein the conditioning device comprises a control device configured for selective control of conditioning braking according to a predetermined schedule of time segments while maintaining an operating speed of the high-speed rail vehicle via the at least one disc brake per axle with at least one carriage control unit and at least one coupling unit.

2. The rail vehicle brake system of claim 1 , wherein the conditioning device provides selective control of the at least one disc brake per axle at the axle level such that the control device is coupled to an axle brake controller of the at least one disc brake.

3. The rail vehicle brake system of claim 1 , wherein the conditioning device provides selective control of the at least one disc brake per axle at the bogie level or/and at the carriage level such that the control device is coupled by means of the carriage control unit to the axle brake controller of each of at least one disc brake per axle.

4. The rail vehicle brake system of claim 1 , wherein the conditioning device is coupled by the at least one coupling unit to the axle brake controller of the at least one disc brake.

5. The rail vehicle brake system of claim 4 , wherein the conditioning device is designed as a closed and independent system with pneumatic actuators and electronic controllers.

6. The rail vehicle brake system of claim 1 wherein the conditioning device further comprises an operating unit.

7. The rail vehicle brake system of claim 1 , wherein the control device of the conditioning device comprises inputs for project-specific factors, wherein the project-specific factors include at least one of speed, vehicle configuration, loading, coefficients of friction, external temperature, traction power, and distance.

8. The rail vehicle brake system of claim 1 , wherein the conditioning device is designed as an integral component of a brake controller, a vehicle controller or as a separate functional unit.

9. The rail vehicle brake system of claim 1 , wherein selective control of respective brake unit is activated in response to the brake temperature falls below a previously defined limit value.

10. A conditioning device for a rail vehicle brake system for a high-speed rail vehicle, wherein the conditioning device comprises a control device configured for selective control of conditioning braking according to a predetermined schedule while maintaining an operating speed of the high-speed rail vehicle via at least one disc brake per axle of the rail vehicle brake system with at least one carriage control unit and at least one coupling unit.

11. A method for the operation of a conditioning device for a rail vehicle brake system for a high-speed rail vehicle, wherein the conditioning device comprises a control device, and is designed for selective control of at least one disc brake per axle of the rail vehicle brake system with at least one carriage control unit and at least one coupling unit, the method comprising:
automatically activating the conditioning device according to a predetermined schedule;
recording project-specific factors at the inputs of the control device of the conditioning device; and
selectively controlling of brake units of the rail vehicle brake system for the operation of the conditioning device to perform conditioning braking while maintaining an operating speed of the high-speed rail vehicle.

12. The method of claim 11 , wherein the activation takes place automatically or/and manually.

13. The method of claim 11 , wherein recording project-specific factors, additional parameters are recorded including temperatures in the immediate vicinity of the brake units or of functional components of the brake units.

14. The method of claim 11 , wherein selective control at the axle, bogie or carriage level is performed in a defined sequence for a defined time depending on the train configuration.

15. The method of claim 11 , wherein selective control with simultaneously recorded measurement values of at least one of vehicle speed, traction power, brake pressure, and brake temperature is regulated such that the operating speed of the whole vehicle is unchanged or is essentially unchanged.

16. The method of claim 11 , wherein selective control using the recorded project-specific factors, control of the friction brakes takes place outside of the defined sequence in response to a factor exceeding or falling below a previously specified limit value.

17. The method of claim 11 , wherein selective control using the recorded project-specific factors, control of the friction brakes takes place outside of the defined sequence if the brake temperature falls below a previously specified limit value.

18. The method for deicing and/or for preventing icing of a brake unit of a rail vehicle brake system for a high-speed rail vehicle, the system including a conditioning device, and at least one disc brake per axle, wherein the conditioning device comprises a control device, and is designed for selective control of the at least one disc brake per axle with at least one carriage control unit and at least one coupling unit, the method comprising:
automatically activating the conditioning device according to a predetermined schedule of time segments;
recording a brake temperature of the brake unit at the inputs of the control device of the conditioning device; and
selectively controlling of brake units of the rail vehicle brake system for deicing and/or for preventing icing of the brake unit.
