GEAR BOX Russian patent published in 2006 - IPC F16H3/66 

FIELD: transport mechanical engineering.

SUBSTANCE: gear box comprises four three-link differential gears. Solar pinion (8) of the first differential gear is connected to input shaft (1) and first brake (25) via first friction clutch (24). Carrier (10) of the brake is connected with second brake (26), carrier (14) of the second differential gear, and epicyclic gear (17) of the third differential gear. Epicyclic gear (9) is connected with third brake (27) and epicyclic gear (13) of the second differential gear. Solar gear (12) of the second differential gear is connected with input shaft (1) and solar pinion (16) of the third differential gear through second friction clutch (28). Carrier (18) of the third differential gear is connected with output shaft (2). Solar pinion (20) of fourth differential gear is connected with epicyclic pinion (17) of the third differential gear, its epicyclic pinion (21) is connected with fourth brake (29), and the carrier is connected with output shaft (2).

EFFECT: enhanced traction of vehicle.
