TRANSMISSION OF TWO-AXIAL ALL-WHEEL DRIVE VEHICLE Russian patent published in 2018 - IPC B60K17/348 

FIELD: machine building.

SUBSTANCE: invention relates to transmission of biaxial four-wheel-drive vehicles. Transmission contains engine (1), clutch and gearbox (2) with driven shaft (3), transfer box (4) with two-stage gear divider. One stage of divider is realized through smooth control transmission. Another stage of divider is provided by cylindrical gear (9) mounted on driven shaft (3) and interacting with moving block of intermediate gears (10) connected to coupling (11). Ending positions of block (10) provide engagement with one of driven links of interaxle differential (13). Output links of latter are connected to main gear (14) provided with inter-wheel differential (15) and drive shafts (16) of one driving axle and to shaft (17), cardan shaft (18) and main transmission (19) of other driving axle.

EFFECT: extension of range of transmission ratio control is achieved.
