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

FIELD: mechanical engineering.

SUBSTANCE: hydromechanical gear box comprises crankcase (1), fluid transformer (2), input link (3), output link (4), planet reduction gear, three friction clutches, and three friction brakes. The planet reduction gear is made of three planet rows. First planet row is made of solar pinion (5), carrier (6) of satellites, and corona pinion (7). Second planet row is made of solar pinion (8), carrier (9) of satellites, and corona pinion. Third planet row is made of solar pinion (11), carrier (12) of satellites, and corona pinion (13). Input link (3) is connected with interconnected solar pinion (8) and solar pinion (11) through friction clutch (14) and with interconnected carrier (9) and (12) through friction clutch (15). Carrier (9) is connected with corona pinion (13) connected with the output link (4) of the gear box through friction clutch (16). Solar pinion (5) is connected with input link (3). Carrier (6) is connected with crankcase (1) of the gear box through friction brake (17). Friction brake (18) connects interconnected carrier (9) and (12) with crankcase (1). Friction brake (19) connects interconnected solar pinion (8) and (11) with crankcase (1).

EFFECT: expanded functional capabilities.
