Transmission unit for use in drive train of motor vehicle, has four planetary gear transmissions arranged next to each other, and output unit rotation fixedly connected to planet carrier of one gear transmission and coupling element

摘要

The transmission unit has a first planetary gear transmission (P1), second planetary gear transmission (P2), third planetary gear transmission (P3) and fourth planetary gear transmission (P4) arranged next to each other along a main axis of rotation (10). A drive unit (11) is connected to a sun gear (P21) of the second planetary gear transmission, a planet carrier (P42) of the fourth planetary gear transmission and a coupling element (S41). An output unit (12) is rotation fixedly connected to a planet carrier (P32) of the third planetary gear transmission and another coupling element (S62).
