TORQUE VECTORING DEVICE Russian patent published in 2016 - IPC F16H48/34 

FIELD: instrument making.

SUBSTANCE: invention relates to differential gears. Disclosed is torque vectoring device (4-18) for two half-axles of a vehicle drive axle. Device (4-18) comprises differential (20-27). Torque vectoring device (4-18) also includes an electric motor (15) connected on one hand to one of half-axles (1), on other hand to housing (24) of differential (20-27) or with its other half-axle (22) by means of differential transmission in form of planetary gear (10). Said structure (7) is made so that motor does not rotate at identical speeds of rotation of one of half-axles (1) and housing (24) or other half-axle (22). Between shaft (1) and structure (7) with shaft, connected with driver (8) of planetary gear row of planetary gear (10), there is first system (4-6) of gear transmissions and planetary row carries planetary gear (9). Between hollow shaft (3) and ring gear (14) of planetary gear there is second system (11-13) of gear transmissions, wherein last gear (13) of second system of gear transmissions can turn on structure (7) with shaft.

EFFECT: compact design.
