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.
Claims10
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 more elements
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.
