  • Patent number: 10763556
    Abstract: A vehicle battery assembly utilizing side cooling plates. This battery assembly avoids a stacked vertical battery and cooling plate or pack arrangement, optimizes tunnel (and other) space utilization, minimizes battery assembly intrusion into the passenger compartment of the associated vehicle, and allows seat position height to be as low as possible within the passenger compartment of the associated vehicle, while still allowing vertical access to the access points and electrical contacts of the battery modules within the battery assembly. Further, such battery assembly is compatible with conventional and novel cooling pipe configurations and cooling systems.
    Type: Grant

  • Patent number: 9130435
    Abstract: A motor vehicle drive unit and an automotive vehicle comprising such a motor vehicle drive unit are provided. An electric motor has a rotor and a main stator rotatably mounted to a support structure. A first transmission provides an output to a first wheel axle shaft from the rotor. A second transmission provides an output to a second wheel axle shaft from the main stator. An auxiliary stator at least partially surrounds the main stator and is held stationary relative to the main rotatably mounted stator. A control unit is provided for controlling the auxiliary stator to add or subtract power to the main rotatably mounted stator.

  • Patent number: 8356584
    Abstract: An engine is disclosed having a flywheel arrangement comprising a starter motor (1) having a pinion gear (2) at an output shaft. The pinion gear (2) constantly engages a corresponding crank gear of a crank wheel (3) located between an engine block and a flywheel assembly (9) of the engine. The crank wheel (3) is operatively connected to a crankshaft (4) of the engine via a one-way clutch unit (5). The flywheel assembly (9) comprises a first flywheel body (6) connected to the crankshaft (4) of the engine. A second flywheel body (7) is rotatable relative to the first flywheel body (6) and coupled thereto such that is able to move elastically through a limited angular distance relative to the first flywheel body (6). An interlocking device includes at least one locking arrangement (8) and is adapted to produce an interlocking connection between the second flywheel body (7) and the first flywheel body (6) during cranking of the internal combustion engine.

  • Publication number: 20080163842
    Abstract: The present invention relates to a starter arrangement for an internal combustion engine. The starter arrangement has a starter motor (1) having a pinion gear (2) at an output shaft. The pinion gear (2) is arranged in constant engagement with a corresponding crank gear of a crank wheel (3) located between an engine block (4) and a flywheel (11) of the engine. The crank wheel (3) is operatively connected to a crankshaft of the engine via a one-way clutch (6). The one-way clutch (6) is arranged at an engine block (4) side of a crankshaft oil seal (7) enabling lubrication and cooling thereof by an engine oil of the engine.
