DEVICE TO DETECT LOCOMOTIVE MOUNTED AXLES SKID BEGINNING Russian patent published in 2013 - IPC B61C15/08 

FIELD: transport.

SUBSTANCE: invention relates to railway transport, particularly, to means for detection of locomotive mounted axles skid beginning in real operating conditions. Speed transducer fitted on the car idle mounted axle to detect beginning of skid. Speed transducer voltage is compared with that of every speed transducer mounted on locomotive drive mounted axles. Note here that difference in voltages of idle mounted axle speed transducer and that of every speed transducer mounted on locomotive drive mounted axles is measured by opposition method in measuring circuit comparator. Proposed device comprises unions for removal of sand left on rails after passage of locomotive. Said compresses air unions are connected to locomotive air system and directed in zone of contact between locomotive wheels and rails on wheel rear side, that is, opposite rolling direction side. Comparator output signal is amplified by supply voltage and fed via relay terminals directly to winding of said feed system pneumoelectric valve.

EFFECT: early detection of skid
