  • Publication number: 20200295628
    Abstract: An electric machine 10 includes a stator with a stator winding with winding heads protruding axially over the stator lamination stack. A winding head is potted with a thermally conductive potting compound which forms an outer circumferential surface and an inner circumferential surface. The outer circumferential surface is in thermally conducting contact with a stator support, and the stator has a cylindrical interior space in which a rotor which is rotatably mounted by a rotor shaft is arranged accompanied by formation of a radial air gap. The electric machine has a first fluid cooling device for wetting the inner circumferential surface of a winding head with a cooling fluid. At least one first fluid conducting element is formed so that a cooling fluid introduced into the interior space is substantially prevented from penetrating into the air gap between rotor and stator.

  • Patent number: 8448730
    Abstract: A multi-axle hybrid drive system for a vehicle which comprises a first unit (4) with an internal combustion engine (5), a separator clutch and a semi-automatic gearshift transmission (6) that is associated with a first, mechanically driven axle (7) of the vehicle. At least one further unit (10), with either wheel-hub motors (8) or with a conventional electric axle drive in combination with an electric machine, such that, in each case, a unit (10) is associated with a respective electrically driven axle (9) of the vehicle. During a gearshift, the vehicle (1) can be driven by the unit (10) associated with the electrically driven axle (9) such that the traction force interruption, occurring in the semi-automatic gearshift transmission (6) during a gearshift, is compensated.

  • Publication number: 20070123384
    Abstract: A transmission for a vehicle equipped with an electrodynamic starting element or an electrodynamic power plant (1) and an electrodynamic starting element or an electrodynamic power plant (1) having an electric motor (2) and a planetary transmission (5) located between the internal combustion engine (4) and the transmission (3) in which the reverse gear is implemented by adequate adjustment of the electric motor (2) of the electrodynamic starting element or of the electrodynamic power plant (1) so that the vehicle is driven in reverse gear by the electric motor (2), the mechanical parts required for the reverse gear with the internal combustion engine (4) being eliminated.
