The present invention relates to the mine rail vehicles. A system of automatic control of skidding and slipping of mine locomotive comprising a traction motor, a hydraulic pump, a valve actuator, a hydraulic plunger and a hydraulic cylinder are included an angular velocity sensor of traction motor, a radar speed sensor of the locomotive, and a computing logic unit, while the latter comprises a calculator of relative wheel slipping and relative angular speed of the traction motor of locomotive and an element OR of comparison of relative slipping the wheel with a reference value. In addition, said computing logic unit comprises an OR element of comparison of relative angular velocity of the locomotive of traction motor and an OR element of comparison of the length of time of current state of the locomotive with a reference value and a longitudinal acceleration sensor of the locomotive. Additionally, the system comprises position sensors of the valve actuator and hydraulic pressure converter. |
