Abstract (en)

[origin: WO2017144153A2] In order to monitor the condition of wheel sets (2) of a rail vehicle (1), the wheel sets having suspension systems (8), using a working device (5) that generates a tilting moment, a change in the suspension travel of the suspension system (8), caused by a wheel-load reduction, is permanently measured by a wheel-load reduction sensor (15). When a pre-set switching mark has been reached, the wheel-load reduction sensor (15) automatically controls a drive unit (6) of the working device (5) in order to prevent a further increase in the tilting moment and/or controls the traction (3). This facilitates more economical use of the rail vehicle (1), since with the wheel-load reduction sensor (15) the working device no longer has to be permanently restricted to extreme situations.
