Abstract

A method for detecting a vibration of a driven axle system of a rail vehicle includes a sensor system detecting a parameter indicating the vibration of an element of the axle system and an evaluating unit evaluating a signal of the sensor system. In order to reliably detect the vibration of the driven axle system of the rail vehicle, the sensor system includes a motion sensor which detects a motion of the element as the parameter.

Claims

1. A method for detecting a rotary vibration of a driven axle system of a rail vehicle, the method comprising the following steps:

providing an element as a part of a bogie of the rail vehicle to which a juddering motion of a driven and juddering axle is transferred;

detecting a parameter indicating a vibration of the element of the axle system by using a sensor system;

detecting the parameter as a movement of the element carried out as a rotation by using a motion sensor of the sensor system, and the movement carried out as a rotation being a rotary movement of the bogie; and

evaluating a signal of the sensor system by using an evaluating unit.

2. The method according to claim 1, which further comprises detecting an acceleration of the element as a parameter by using an acceleration sensor of the sensor system.

3. The method according to claim 1, wherein the motion sensor is a rotation sensor.

4. The method according to claim 1, wherein the sensor system, 32) includes a sensor of an inertial navigation system.

5. The method according to claim 1, which further comprises filtering the signal of the sensor system to a frequency band lying about a natural oscillation of the vibration.

6. The method according to claim 1, which further comprises detecting the vibration from a longitudinal movement and a rotary movement of the element.

7. The method according to claim 1, which further comprises concluding one of a plurality of types of vibration from signals of a plurality of motion sensors.

8. The method according to claim 1, which further comprises concluding a place of origin of the vibration from signals of a plurality of motion sensors.

9. The method according to claim 1, which further comprises concluding a strength of the element from sensor data.

10. A rail vehicle, comprising:

a bogie including a driven axle system having a driven and juddering axle and an element to which a juddering motion of said driven and juddering axle is transferred;

a sensor system for detecting a parameter indicating a rotary vibration of said element of said axle system, said sensor system including a motion sensor, said parameter being movement of said element carried out as a rotation, and said movement carried out as a rotation being a rotary movement of said bogie; and

an evaluating unit for evaluating a signal of said sensor system.
