HYDROMECHANICAL GEAR BOX

摘要

FIELD: automotive industry. ^ SUBSTANCE: hydromechanical gear box comprises hydromechanical torque converter (2) and planet reduction gear. Carrier (6) of the first planet row is connecter with crankcase of gear box (1) through friction brake (17). Corona pinion (17) of the first planet row is connected with carrier (12) of the third planet row that represents output link (4) of the gear box. Output member (3) of the hydrodynamic torque converter is connected with solar pinion (5) of the first planet row through controllable clutch (15). Solar pinion (11) of the third planet row is connected with the crankcase of the gear box through friction brake (18). Solar pinion (5) of the first 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 solar pinion (8) of the second planet row. Output members (3) of the hydrodynamic torque converter is connected with carrier (9) of the second planet row. Carrier (6) of the first planet row is connected with corona pinion (10) of the second planet row through friction controllable clutch (14). ^ EFFECT: expanded functional capabilities. ^ 8 cl, 11 dwg
