  • 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.

  • Publication number: 20200056680
    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.

  • Publication number: 20190293153
    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.

  • Publication number: 20190039447
    Abstract: A transmission (G) for a motor vehicle includes an input shaft (GW1), an output shaft (GW2), a differential gear (AG), an interface (IF) to a transmission-external drive unit, an electric machine (EM) with a rotationally fixed stator (S) and a rotary rotor (R), a plurality of planetary gear sets (PS, PV), and a plurality of shift elements (A, B, C, D, E). The electric machine (EM) is arranged at an axial end of the transmission (G) which is positioned opposite the interface (IF) to the transmission-external drive unit. An area (X) directly adjacent to the differential gear (AG) is configured for accommodating a joint (GL) of a motor vehicle side shaft (DS) and is arranged completely or at least in part in an installation space radially outside the electric machine (EM).

  • Patent number: 10125867
    Abstract: A device for actuating multiple shift elements of a transmission device is described. Each of the pistons for a change in operating state of the shift elements in the area of active surfaces can be subjected to a fluid pressure acting in a first or second actuating direction. The fluid pressure actively applied in the first actuating direction can be separately adjusted for each of the shift elements, while the fluid pressure actively applied in the second actuating direction is essentially the same for all shift elements. The pistons are arranged coaxially to each other, radially into each other, and in a manner axially displaceable in sections in one intermediate plate. The intermediate plate features areas for applying the fluid pressures acting in the first actuating direction. The area through which the fluid pressure acting in the second actuating direction can be guided to the pistons is limited.
