HYDROMECHANICAL GEAR BOX Russian patent published in 2006 - IPC F16H3/62 B60K17/10 F16H47/08 

FIELD: automotive industry.

SUBSTANCE: hydromechanical gear box comprises hydrodynamic torque converter (2) and planet reduction gear. Carrier (6) of the first planet row is connected with the crankcase of gear box (1) through friction brake (17). Corona pinion (7) of the first planet row is connected with carrier (12) of the third planet row that is output link (4) of the gear box. Output member (3) of the hydrodynamic converter of torque is connected with solar pinion (8) of the second planet row and with solar pinion (5) of the first planet row through friction controllable clutch (15). Solar pinion (11) of the third planet row is connected with the crankcase of the gear box through friction brake (16). Corona pinion (10) of the second planet row is connected with corona pinion (13) of the third planet row. Carrier (6) of the first planet row is connected with carrier (9) of the second planet row. The solar pinion of the second planet row is connected with corona pinion (10) of the second planet row through the friction clutch.

EFFECT: expanded functional capabilities and prolonged service life.
