Suspension failure detection in a rail vehicle

摘要

The invention relates to a rail vehicle, including a wagon body and a suspension system having a running gear supporting the wagon body. A sensor device and a control device are provided. The sensor device capturing an actual value of at least one status variable being representative of a spatial relationship between a first reference part of the sensor device associated to a part of the running gear and a second reference part of the sensor device associated to the wagon body. The control device performs a malfunction analysis using the actual value of the status variable, the malfunction analysis assessing fulfillment of at least one predetermined malfunction criterion. The control device provides a malfunction signal if the malfunction analysis reveals that the malfunction criterion is fulfilled.

1. A rail vehicle, comprising:
a wagon body and a suspension system comprising a running gear supporting said wagon body wherein a sensor device and a control device are provided; said sensor device capturing an actual value of at least one status variable, said status variable being representative of a spatial relationship between a first reference part of said sensor device associated to a part of said running gear and a second reference part of said sensor device associated to said wagon body; said control device performing a malfunction analysis using said actual value of said status variable and at least one predetermined malfunction criterion, said malfunction analysis assessing fulfillment of the at least one predetermined malfunction criterion and considering pre-definable allowable limits of a relative motion between said running gear and said wagon body; and said control device providing a malfunction signal if said malfunction analysis reveals that said malfunction criterion is fulfilled.
