TRANSMISSION OF A VEHICLE Russian patent published in 2019 - IPC B60K17/346 

FIELD: machine building.

SUBSTANCE: invention relates to multi-axle all-wheeled wheeled vehicle transmissions. Transmission comprises located before engine gearbox, installed on its output main shaft, transfer box, equipped with gears of first stage of torque transfer, connected by means of main shaft with gearbox, and gear wheels of second and additional stages of torque transmission to drives of rear third and fourth bridges and drives of front first and second bridges, multiple driving and intermediate shafts, mechanisms for transmission of drive and wheel gearboxes. First driving shaft is connected by its input end to the axis of the gear wheel of the second gear of transfer gear torque of the transfer gearbox and the output end – to the input of the drive mechanism of the drive of the rear fourth bridge. Second drive shaft is connected by the input end to the output of the drive mechanism of the drive of the rear fourth bridge and the output end is connected to the input of the gear of the drive of the rear third bridge. Third drive shaft is connected by its input end to the axis of the gear wheel of the additional gearing stage of transfer gear torque of the transfer gearbox and the output end – to the input of the drive mechanism of the front second axle drive. Fourth driving shaft is connected by the input end to the output of the transmission mechanism of the drive of the front second bridge and the output end - to the input of the drive mechanism of the front first axle drive. Second axle drive transmission mechanism is equipped with interaxle differential. Distributing box is equipped with braking device and differential engaged with gear wheel of second stage of torque transmission and differential, which is made with possibility of switching on and blocking differential transfer of torque from gear wheels of second stage to drive of drive shafts of front and rear bridges.

EFFECT: broader layout capabilities, reduced overall dimensions and improved transmission performance.
