  • MULTI-MODE ELECTRIC DRIVE HYBRID TRANSMISSION
    Publication number: 20120270691
    Abstract: A hybrid powertrain for a vehicle having a disconnect clutch located between an internal combustion engine, or other power source, and a hybrid transmission. When deactivated, the disconnect clutch decouples the engine from the hybrid transmission, which enables the hybrid transmission input shaft to rotate independently of the internal combustion engine. This enables enhanced electric drive performance for the hybrid transmission. The disconnect clutch provides for internal combustion engine starting, including internal combustion starting at high vehicle speeds.

  • Hybrid transmission
    Publication number: 20090156351
    Abstract: In a hybrid transmission for a motor vehicle with three differential drive units (D1 to D3), two electric machines (E1, E2) and four shift elements (C1 to C4), the hybrid transmission (HG) includes a fifth shift element (C5) by which two transmission elements of the first differential drive unit (D1) can be coupled thereby achieving an improved operating efficiency and smaller continuous electric power requirements.
