  • Patent number: 8087483
    Abstract: A hybrid powertrain is provided that provides engine starting from an electric-only mode with a reduced torque load on the motor/generator. The powertrain includes an engine and a motor/generator, which may be a single motor/generator in a strong or full hybrid, but is not limited to such. The motor provides propulsion torque in an electric-only operating mode, and is configured to apply torque to a transmission input member. A first clutch is selectively engagable to connect the engine output member for common rotation with the transmission input member. An engine starting mechanism is provided that multiplies motor torque used to start the engine so that less is diverted from propelling the vehicle, enabling a smaller motor/generator to be used. A method of controlling such a powertrain is also provided.

  • Publication number: 20110306463
    Abstract: An automated manual transmission system (1) including an input shaft (4), a clutch, an output shaft (6), and a gear-box enabling selection of different transmission ratios between the input shaft and the output shaft (6). An actuation mechanism (10) is operatively connected to the clutch and the gearbox to effect disengagement and re-engagement of the clutch and coordinated selection of the transmission ratios. A hybrid motor (14) is operably connected to the output shaft (6) and a control system (16) is operable to regulate the actuating mechanism in response to control inputs, to effect automatic gear changes. The hybrid motor (14) is responsive to the control system (16) to provide supplementary torque to the vehicle driveline when the clutch is disengaged, to reduce torque interruption in the driveline.

    Abstract: A hybrid drive for a motor vehicle which has a combustion engine, a transmission with a transmission input shaft which can be coupled with the combustion engine, and an electric machine which is positioned between the combustion engine and the transmission. The electric machine has a stator and a rotor which interacts with the transmission input shaft and is supported by a transmission housing input part. The transmission input shaft is supported, by a fixed radial bearing and a spaced radial bearing, in a bearing journal of the transmission housing input part. The rotor is connected, in a rotationally fixed manner, to an extension of the transmission input shaft which protrudes from a bearing journal. A radial shaft seal is positioned at the end of the bearing journal, facing the rotor, and the two radial bearings are cooled and lubricated by transmission oil.

  • Publication number: 20110239819
    Abstract: Provided is a transmission for a hybrid vehicle which permits a compact, lightweight structure and yet allows the power of an internal combustion engine to be disconnected and which is capable of efficiently transmitting power without complicating the control. The transmission includes a speed changing unit which has a first input shaft 3 connected to a power shaft 6 of an internal combustion engine 1 and a second input shaft 4 connected to a power shaft of a motor 2 and which establishes a plurality of gear shift stages. A one-way clutch 7 is interposed between the power shaft 6 of the internal combustion engine 1 and the first input shaft 3. The one-way clutch 7 disengages the connection between the power shaft 6 of the internal combustion engine 1 and the first input shaft 3 when the rotational speed of the power shaft 6 of the internal combustion engine 1 is lower than the rotational speed of the first input shaft. 3.
