VEHICLE POWER TRANSMISSION WITH HYDRODYNAMIC CONTROL OF POWER FOR AUXILIARY TRACK PROPULSOR Russian patent published in 2007 - IPC B60K17/34 B60K23/08 

FIELD: transport engineering.

SUBSTANCE: invention can be used in tractors, self-propelled machines, automobiles, half-track prime movers and carriers. Proposed power transmission has engine 1, gearbox 2, transfer case 3, front axle 4 and rear axle 5 of wheel propulsor, hydrodynamic torque converters 6 and 7, and sensors 10 coupled with automatic control 11. Torque from engine 1 is transmitted through gearbox 2 to transfer case 3 which distributes torque between driving axles 4 and 5 and impellers of hydrodynamic torque converters 6 and 7 whose are coupled with driving sprockets 8 and 9 of track propulsor. Reactors of torque converters change angle of blade tilting depending on control signals from automatic control 11 receiving information on current values of torque from sensors 10 installed on shafts of wheel propulsor drive.

EFFECT: increased traction and speed traction and speed characteristics of vehicle, improved steerability and increased efficiency of drive.
