Transmission device i.e. motor vehicle transmission device, has output unit and two planetary gear carriers fixedly connected together, and sun wheel fixedly connected to transmission case

摘要

The device has four planetary gear trains (P1-P4) arranged one behind the other along a main rotation axis (10). Six coupling units (S1-S6) are connected with nine forward gears, and a drive unit (11) and three coupling elements (S12, S22, S32) are fixedly connected together. An output unit (12) and two planetary gear carriers (P32, P43) are fixedly connected together. A sun wheel (P21) is fixedly connected to a transmission case (13).
