  • Hybrid transmission
    Patent number: 7918756
    Abstract: In a hybrid transmission for a hybrid motor vehicle, with split power driving ranges, discrete gear steps and two electric drive motors (33, 34), a transmission arrangement is provided which results in low rotational speeds of the transmission elements, in particular of the planets while at the same time, the electric drive motors (33, 34) are disposed adjacent to one another at the input end of the transmission next to an internal combustion engine to which the transmission is connected.
    Type: Grant

  • Power-Split Transmission for a Hybrid Vehicle
    Publication number: 20080171625
    Abstract: The invention relates to power-split transmission for a hybrid vehicle having an internal combustion engine, wherein the transmission has two electric motors (E1, E2) and a plurality of planetary gearings (N1, N2, N3, N4), and wherein for starting in a first driving range, a single power-split structure is provided at the input side, which structure is adjoined in a further driving range by a double power split. A further single power split for an overdrive adjoins these in a final driving range.
