Another element (E2, 22E2a, 22E2b) of one of the planetary gear sets (P1, 2P3, 2P5) is permanently connected to a rotor (R) of the electric machine (EM). By engaging an auxiliary shift element (ZS, 2ZSa, 2ZSb), which is a form-locking shift element, the rotor (R) and the input shaft (GW1) can be brought into a fixed rotational speed relationship with respect to each other.

    Abstract: A multi-speed transmission has drive and output shafts, three front-mounted and two rear-mounted planetary gear sets, and shift elements which can be engaged to selectively implement at least eleven forward gears and one reverse gear. The front gear sets are connected to one element of the rear gear sets. Five shift elements are assigned to the front gear sets and two are assigned to the rear gear sets, such that the front gear sets transmit seven output speeds to the rear gear sets. If normalized to the input speed of the drive shaft, at least one output speed of the front gear sets is less than 0, one output speed is greater than 1, one output speed is equal to 0, one output speed is equal to 1 and two output speeds are between 0 and 1.

  • Patent number: 10955031
    Abstract: A multi-speed transmission having drive and output shafts, front-mounted planetary gearsets, rear-mounted planetary gearsets and six shift elements. Selective engagement of shift elements selectively renders a drive shaft speed and speeds generated in the front gearsets for achieving a reverse gear and twelve forward gears via the rear gearsets transmissible as an output speed to the output shaft. Four shift elements are assigned to the front gearsets and two are assigned to the rear gearsets. At least one front gearset is rigidly connected to an element of the rear gearsets, resulting in six different output speeds of the front gearsets being transmissible to the rear gearsets. If normalized to the drive shaft input speed, one output speed is smaller than 0, three output speeds are between 0 and 1, one output speed is equal to 1 and one output speed is greater than 1.

  • Patent number: 10766350
    Abstract: A transmission for a motor vehicle having an input shaft, an output shaft, a plurality of planetary gear sets, a plurality of shift elements, and an electric machine arranged axially parallel to the input shaft and operatively connected to the input shaft with a constant transmission ratio via a spur gear drive or a flexible traction drive mechanism. Various gear steps are formable between the input shaft and the output shaft through the planetary gear sets by selectively engaging shift elements of the plurality of shift elements. An actuating element of one of the plurality of shift elements is arranged, at least partially, radially within an element of the spur gear drive or the flexible traction drive mechanism arranged coaxially to the input shaft, and together with the spur gear drive or the flexible traction drive mechanism in a plane orthogonal to an axis of rotation of the input shaft.

  • Patent number: 10759265
    Abstract: A transmission having five planetary gearsets and seven shift elements for achieving various ratios between drive and output shafts. A forward gearset has three shafts. Two intermediate gearsets have four shafts. Two main gearsets have at least four shafts. Depending on the shift states of the second and third shift elements, the forward gearset can generate two rotational speeds at the output side, which transfer from a forward gearset shaft to an intermediate gearset shaft. Depending on the shift states of the first to fifth shift elements, the intermediate gearset can generate eight rotational speeds at the output side, which pass from another intermediate gearset shaft to a main gearset shaft. Depending on the shift states of the seven shift elements, the main gearset can generate up to fourteen forward and two reverse gears at the output side, which are transferred by another main gearset shaft to the output shaft.
