Abstract

A control unit for a rail vehicle, comprising a braking control unit that contains an electronic braking control device for emitting control commands to brake actuators and/or comprising an anti-skid device, which controls the wheel slip of the wheels of at least one axle in accordance with at least one rotational speed signal from an anti-skid sensor. The control unit also comprises a roll monitoring unit with an electronic roll monitoring control device and at least one roll monitoring sensor for detecting the rotational speed of at least some wheels in the form of a rotational speed signal, and comprises a rolling gear monitoring unit for monitoring and/or diagnosing critical conditions of and damage to the rolling gear. The monitoring unit comprises an electronic control device for monitoring the rolling gear. The electronic control device for monitoring the rolling gear and/or the electronic anti-skid control device and/or the electronic braking control device and/or the electronic roll monitoring control device are combined to form a structural unit.

Claims

1. A control device for a rail vehicle comprising:

a rolling gear monitoring device for monitoring critical states and damage of a rolling gear,

one of a)a brake control device including an electronic brake control unit for outputting control commands to brake actuators b)an anti-skid device which controls the wheel slip of the wheels of at least one axle as a function of at least one rotational speed signal supplied to an electronic anti-skid control unit by an anti-skid sensor (10), and c) a roll monitoring device including an electronic roll monitoring control unit and at least one roll monitoring sensor for sensing the rotational speed of at least a number of wheels in the form of a rotational speed signal, and

wherein the electronic rolling gear monitoring control unit is combined with at least one of the electronic anti-skid control unit, the electronic brake control unit and the electronic roll monitoring control unit to form one structural unit.

2. The control device as claimed in claim 1, wherein the rolling gear monitoring control unit evaluates the rotational speed signal of one of the roll monitoring sensor and the anti-skid sensor.

3. The control device as claimed in claim 1, wherein a housing of the electronic rolling gear monitoring control unit and a housing of one of the electronic anti-skid control unit, the electronic brake control device and the roll monitoring control unit are connected to one another by flanges to form the structural unit.

4. The control device as claimed in claim 1, wherein at least part of the electronic rolling gear monitoring control unit and a part of one of the electronic anti-skid control unit, the electronic brake control unit and the roll monitoring control unit are accommodated in a common housing to form the structural unit.

5. The control device as claimed in claim 1, wherein the rolling gear monitoring device (36) and one of the anti-skid device, the brake control device and the roll monitoring device have at least one of a common power supply and a common interface for communicating with an operator and/or a vehicle control system.

6. The control device as claimed in claim 5, wherein the common interface for communicating with a vehicle control system is connected to a vehicle bus.

7. The control device as claimed in claim 6, wherein the vehicle control system has a display device for signaling critical states which the rolling gear monitoring device has detected.

8. The control device as claimed in claim 1, wherein one of the roll monitoring sensor and the anti-skid sensor is a combination sensor which, apart from the signal for the rotational speed of at least one wheel or an axle, modulates a signal for one of the temperature of a wheel set bearing and an oscillation signal for oscillations occurring at the wheel set bearing.

9. The control device as claimed in claim 8, wherein the combination sensor is arranged in one of directly on the wheel set bearing and in the direct vicinity of the wheel set bearing (18).

10. A rail vehicle containing a control device of claim 1.

11. The control device as claimed in claim 1, wherein single sensor is used for both the roll monitoring sensor to provide the signal for the rotational speed of at least one wheel or an axle.

12. A control device for a rail vehicle comprising:

a rolling gear monitoring device for monitoring critical states and damage of a rolling gear;

one of a) an anti-skid device which controls the wheel slip of the wheels of at least one axle as a function of at least one rotational speed signal and b) a roll monitoring device including an electronic roll monitoring control unit which receives a rotational speed signal, and

a combination sensor for providing the rotational speed signal to one of the anti-skid device and the roll monitoring control device and providing a signal for one of the temperature of a wheel set bearing and for oscillations occurring at the wheel set bearing to the rolling gear monitoring device.
