1. A device for monitoring undercarriage components of rail vehicles for faults, said device comprising at least one acceleration sensor which interacts with an evaluation device, wherein at least one acceleration sensor is arranged on the undercarriage of the rail vehicle in such a way that its detection direction has at least one component parallel to the vertical axis of the rail vehicle, wherein:

  • the acceleration sensor is embodied in such a way that it supplies a measurement signal which contains a signal component which corresponds to the acceleration due to gravity or constitutes a signal which corresponds to the acceleration due to gravity, and in that the evaluation device comprises a routine for checking the function of the acceleration sensor, which routine modulates a fault signal if the measurement signal which is supplied by the acceleration sensor does not contain a signal component which corresponds to the acceleration due to gravity or does not constitute a signal which corresponds to the acceleration due to gravity and suppresses the fault signal if this is not the case.
