DEVICE FOR INCREASING LOCOMOTIVE TRACTION EFFORT Russian patent published in 2018 - IPC B61C15/08 

FIELD: transportation.

SUBSTANCE: device for increasing the locomotive traction effort includes a system for supplying sand under the locomotive wheels, a system of additional air ducts arranged in pairs on both sides of the extreme wheelsets of bogies, and butterfly throttles for switching the compressed air flow direction. The system of additional air ducts is equipped with one or several compressed air distribution chambers, in which high pressure is always maintained. The additional air ducts are equipped at the ends with diffusers dividing the air flow into several differently directed jets. The locomotive is equipped with a suction plant connected to a waste sand collecting chamber, in which a reduced pressure is constantly maintained, which in turn is connected by means of pipelines with exhaust pipes installed in pairs on both sides of the wheelsets. The exhaust pipes are equipped with branch pipes covering the upper part of the rail with a clearance.

EFFECT: increased traction effort of the locomotive.
