  • Patent number: 12580457
    Abstract: The described examples may relate to a connection device for electrically conductively connecting a stator and a pulse inverter of an electric motor. The connection device includes at least one clamping piece pair with two clamping pieces, which are movable in relation to each other along a clamping direction between a closed and an open position and formed to clamp a stator-side line end with a pulse inverter-side line end between the two clamping pieces in the closed position such that an electrically conductive connection of the line ends is established.
    Type: Grant

  • Patent number: 12519386
    Abstract: A drive device for a vehicle, including an electric machine having a stator housing, on whose outer circumference a pulse width modulated inverter housing is formed, in which a pulse width modulated inverter having at least one pulse width modulated inverter contact is arranged, which is connected to a stator contact via a contact bridge, an AC filter being assigned to the contact bridge to reduce common mode flows and/or for the purpose of EMC shielding. According to the invention, the AC filter is a component separate from the pulse width modulated inverter and may be mounted in the pulse width modulated inverter housing independently of the pulse width modulated inverter.

  • Patent number: 12000471
    Abstract: A spur gear includes a radially outer, spur-cut gear rim, a radially inner hub, and a rotationally symmetrical radial connecting structure which integrally connects the gear rim to the hub. The radial connecting structure has mutually spaced struts, which extend between the hub and the gear rim, and axial perforations or holes, which are situated between the struts. The radial connecting structure has a disk-shaped base body, through which the axial holes pass and which has an axial front side and an axial rear side, with the struts being situated on the front side.

  • Patent number: 8155861
    Abstract: In a method for controlling a fuel supply system of an internal combustion engine with at least one combustion chamber, into which fuel can be injected via a fuel injector, the fuel injector being activated for the implementation of a normal start-up with specified injection parameters when the fuel supply system is filled, the specified injection parameters are modified for the acceleration of an initial start-up of the internal combustion engine when a filling of the fuel supply system with fuel has been implemented to evacuate the air from said fuel supply system.
