Abstract
The invention provides a railway rail car torque converter reverse drag lubrication system. A hydraulic control system is arranged at an inertia shaft output end of a torque converter, so when a vehicle runs in a positive direction or a reverse direction, the hydraulic control system sucks oil from an oil bottom case of the torque converter, and in addition, oil liquid is drained back into the oil bottom case of the torque converter through the hydraulic control system. In the motive-less running process of the vehicle, the hydraulic control system sucks oil from the oil bottom case of the torque converter, and in addition, the oil liquid enters a lubricating oil passage of the torque converter through the hydraulic control system for lubricating a rotating bearing arranged at the inside. The railway rail car torque converter reverse drag lubrication system has the advantages that a forced lubricating function of the torque converter under the power-less work condition can be realized, convenience, high speed and reliability are realized, and a reverse drag function of the vehicle can be realized without dismounting a transmission shaft.
