| 摘要 |
The invention relates to a powershift multistep transmission (LMG) between a drive shaft (an) and an output shaft (ab=2), comprising a plurality of gear steps (GS) and a plurality of shifting elements (SE). The drive shaft (an) drives a first shaft assembly (WS1), which comprises at least one triple-shaft planetary gear step (PG) and can be connected via at least two, preferably three spur pinion sets (SG) to a second shaft assembly (WS2), also comprising at least one triple-shaft planetary gear step. The transmission comprises a total of three planetary gear steps (PG1, PG2, PG3) and three spur pinion sets (SG36, SG47, SG58). With only five shifting elements, eight forward gears and one reverse gear can be shifted. By dividing the transmission elements into two shaft assemblies, the transmission is suitable for front transversal uses and longitudinal uses. All shifting elements can be easily filled with oil pressure. The shaft assemblies 47 and 54 are further suitable for connecting an electric machine for mild hybrid drives. With only four shifting elements, the transmission still has five well-stepped forward gears and one reverse gear. |
