  • Patent number: 9599196
    Abstract: A transmission includes a drive shaft (1), an output shaft (2), a housing (G), a first planetary gear set (PR1), a second planetary gear set (PR2) and a third planetary gear set (PR3), and six shift elements, including a first brake (B1), a second brake (B2) along with a first clutch (K1), a second clutch (K2), a third clutch (K3, K3?, K3?, K3??) and a fourth clutch (K4, K4?). The shift elements are selectively actuated, by which nine forward gears and one reverse gear can be realized through different transmission ratios between the drive shaft (1) and the output shaft (2). Each planetary gear set (PR1, PR2, PR3) has a sun gear (S1, S2, S3), one planetary gear, one planetary carrier (PT1, PT2, PT3) and one ring gear (H1, H2, H3).
