VEHICLE POWER TRANSMISSION WITH HYDRODYNAMIC CONTROL OF POWER TRANSMITTED TO WHEELED AND CRAWLER PROPULSIVE DEVICE Russian patent published in 2007 - IPC B60K17/34 

FIELD: transport engineering.

SUBSTANCE: invention can be used in tractors, self-propelled vehicles, automobiles, half-track tractors and transporters. Drive of driving axles of wheeled propulsive device has mechanical transmission rigidly coupled with epicyclic gear provided with external and internal gear rim, and drive of driving axle of crawler propulsive device furnished with mechanical and hydrodynamic transmission is rigidly coupled with carrier of planetary train. Drive shaft of wheeled propulsive device is coupled with external gear rim of epicyclic gear, and drive shaft of crawler propulsive device is coupled with carrier provided with gear of hydrodynamic transmission which is coupled with epicyclic gear through direct-transparency torque converter. Torque converter pump wheel shaft is coupled with external gear rim of epicyclic gear, and turbine wheel shaft, with gear of hydrodynamic transmission.

EFFECT: increased traction and speed characteristics of vehicle, increased service life of crawler propulsive device, efficiency of drive and its simplified design.
