HYDROMECHANICAL GEAR BOX Russian patent published in 2006 - IPC F16H3/66 F16H47/08 B60K17/08 

FIELD: mechanical engineering.

SUBSTANCE: hydromechanical gear box comprises crankcase (1), torsional vibration damper (2), input link (3), output link (4), planet gear made of three planet rows, two friction clutches, and four friction brakes. 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). Input link (3) is connected with corona pinion (13) and carrier (9) through friction clutch (14). Input link (3) is connected corona pinion (10) and solar pinion (11) through friction clutch (15). Carrier (6) is connected with input link (3). Input link (3) is connected with torsional vibration damper (2). Friction brake (16) connects corona pinion (10) and solar pinion (11) with crankcase (1) of the gear box. Friction brake (17) connects corona pinion (13) and carrier (9) with crankcase (1) of the gear box. Friction brake (18) connects solar pinion (5) and solar pinion (8) with crankcase (1) of the gear box. Corona pinion (7) is connected with crankcase (1) through friction brake (19). Carrier (12) is connected with output link (4) of the gear box.

EFFECT: expanded functional capabilities and prolonged service life.
