Transmission unit, particularly motor vehicle hybrid transmission unit, comprises three planetary gear trains, and four coupling units, where drive unit is provided, which is connected with former planetary gear train

摘要

The transmission unit comprises three planetary gear trains (P1a to P3a), and four coupling units (S1a to S4a). A drive unit (11a) is provided, which is connected with the former planetary gear train and a planet carrier (P32a) of the third planetary gear train in a torque-proof manner. Another drive unit (12a) is provided, which is connected with another planet carrier (P22a) of the latter planetary gear train in a torque-proof manner.
