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

FIELD: transport engineering.

SUBSTANCE: invention relates to planetary transmission used in vehicle automatic transmission systems. Proposed transmission contains hydrodynamic torque converter 2 and planetary reduction gear. Carrier 6 of first planetary gear train is coupled by friction brake 17 with transmission case. Crown gear 7 of first planetary gear train is coupled with carrier 12 of third planetary gear train being output member 4 of transmission. Output member 3 of hydrodynamic torque converter is coupled with sun gear 8 second planetary gear train and by friction controlled clutch 15 with sun gear 5 of first planetary gear train. Sun gear 11 of third planetary gear is coupled by friction brake 18 with transmission case. Output member 3 of hydraulic torque converter is coupled by friction controlled clutch 14 with carrier 6 of first planetary gear train. Sun gear 5 of first planetary gear train is coupled by friction brake 16 with transmission case 1. Crown gear 10 of second planetary gear train is coupled with crown gear 13 of third planetary gear train. Carrier 6 of first planetary gear train is coupled with carrier 9 of second planetary gear train.

EFFECT: enlarged kinematic capabilities increased service life of transmission.
