FIELD: machine building.
SUBSTANCE: invention relates to devices, indicating slipping or yoke of wheels. Railway transport wheelset slipping prediction device comprises wheelset drive mechanical part oscillation sensor, analogue-to-digital converter, band-pass filter tuned to an informative frequency band and a signal strength generation circuit, a current signal generating unit, a reference signal strength generating unit, a unit for comparing signal levels, which establishes a logic output signal, and a controlled input switch for generating a reference signal level. Oscillation sensor is connected to an analogue-to-digital converter, the output of which is connected to the input of the band-pass filter, the output of which is connected to the input of the unit for generating the reference signal level. At that, control unit of signal input switch of reference signal level generating unit comprises output logic delay unit.
EFFECT: avoiding false actuations immediately after traction drive exits pre-driving mode.
