摘要

The transmission has a first clutch (17) that is connected to a second clutch (67) of a third planetary gear set (P3) through a seventh shaft (7). A third shaft (3) is connected with a first brake (03) coupled to the housing (G) of a second planetary gear set (P2). A fourth shaft (4) is connected to a second brake (04) coupled to the housing of a first planetary gear set (P1). An output shaft (2) is connected with the third and fourth planetary gear sets (P4). The first planetary gear set is connected to a fifth shaft (5) coupled to the housing by a third brake (05).
