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 consists of three planet rows. First planet row is made of solar pinion (5), carrier (6) of satellites, and corona gear (7). Second planet row is made of solar pinion (8), carrier (9) of satellites, and corona gear (10). Third planet row is made of solar pinion (11), carrier (12) of satellites, and corona gear (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 carrier (12) through friction clutch (15). Carrier (9) is connected with corona gear (10) connected with corona gear (7) through friction clutch (16). Solar pinion (5) is connected with output link (3). Carrier (6) is connected with crankcase (1) of the gear box through friction brake (17). Friction brake (18) connects interconnected carries (9) and (12) with crankcase (1). Friction brake (19) connects interconnected solar gear (8) and (11) with crankcase (1).

EFFECT: expanded functional capabilities.
