VEHICLE POWER TRAIN WITH ADJUSTABLE VALUE OF KINEMATIC MISMATCH Russian patent published in 2007 - IPC B60K17/346 F16H39/02 

FIELD: transport engineering.

SUBSTANCE: invention can be used in tractors, self-propelled vehicles, automobiles, wheeled and crawler tractor and carriers. Vehicle contains engine which is coupled through gearbox and first planetary mechanism with drive of track driving axle. Engine is coupled through said gearbox, second planetary mechanism and differential with drive of wheel driving axle. Vehicle is furnished with hydrostatic transmission with adjustable hydraulic motor. Hydraulic motor is coupled through gear installed on its shaft with epicyclic gears of above-indicated planetary mechanisms. Hydrostatic transmission is cut into operation automatically after delivery of signal from comparing device to electromagnetic distributor. Comparing device receives signals from pickups installed on shafts which respond to load on shafts of wheel and track drives. Hydrostatic transmission can be cut into operation manually after disconnection of comparing device from system by directly acting onto spool of electromagnetic distributor.

EFFECT: increased cross-country capacity, optimization of distributions of longitudinal pushing forces developed by different types of propulsion devices, increased service life of tracks owing to adjustment of kinematic mismatch of different type propulsion devices.
