HYDROMECHANICAL GEAR BOX Russian patent published in 2006 - IPC F16H3/66 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, two friction clutches, and four friction brakes. The planet reduction gear is made of four 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 (10). Third planet row is made of solar pinion (11), carrier (12) of satellites, and corona pinion (13). Fourth planet row is made of solar pinion (14), carrier (15) of satellites, and corona pinion (16). Solar pinion (5) is connected with crankcase (1) of the gear box via friction brake (17). Friction brake (18) connects interconnected carrier (6) and (9) with crankcase (1). Friction brake (19) connects interconnected corona pinion (10) and solar pinion (14) with crankcase (1). Friction brake (20) connects interconnected carrier (15) and corona pinion (13) with crankcase (1) of the gear box. Output link (3) of the fluid transformer is connected with interconnected corona pinion (13) and carrier (15) via friction clutch (210 and with solar pinion (11) via friction clutch (22). Solar pinion (8) and corona pinion (7) are connected with input link (3).

EFFECT: expanded functional capabilities and prolonged service life.
