  • Patent number: 7952255
    Abstract: A rotor and an electrical machine for a motor vehicle drivetrain. The rotor includes a rotor carrier with a radial supporting area, an axial supporting area, which extends axially with respect to the axis of rotation of the rotor and which is connected to the radial supporting area and has an inner or an outer first circumferential surface, and a rotor component which conducts magnetic flux and is arranged at the circumferential surface of the axial supporting area. To achieve a rotationally locking connection between the rotor carrier and the rotor component conducting magnetic flux, it is proposed to form the axial supporting area with a positive engagement profile which extends in axial direction of the rotor for receiving, in a positive engagement, the rotor component conducting magnetic flux.

  • Patent number: 7514828
    Abstract: A stator for an electrical machine includes a plurality of coils arranged on a stator yoke, each coil having a pair of ends; a plurality of linking conductors which are electrically insulated from each other, each conductor having a terminal element electrically connected to two ends of two adjacent coils; and a support structure mounted on the stator yoke, the support structure having a receiving channel which holds the linking conductors and a wiring channel into which the terminal elements and the ends of the coils project. The terminal elements and the ends of the coils are electrically connected by conductor bridge elements arranged serially in the wiring channel.

  • Patent number: 7365460
    Abstract: In a plurality of stator coils arranged on the yoke, each coil has a pair of ends, each end being adjacent to a respective end of an adjacent coil to form pairs of adjacent ends. A plurality of mutually insulated concentrically arranged linking conductors each has a plurality of circumferentially arranged terminal elements, each terminal element being electrically connected to a respective pair of adjacent ends to form a contact area in a common axial and radial position.

  • Patent number: 7216750
    Abstract: A clutch arrangement for a motor vehicle has a clutch housing that is filled with pumped medium in the form of fluid, a first friction element being rotatable in common with the clutch housing. Further, a second friction element is provided which is rotatable in common with a driven member and which can be brought into an operative connection with the at least one first friction element for producing a frictional interaction. At least one first friction element and at least one second friction element are each provided with a support component that can be provided for receiving at least one friction lining. The support components have support component segments which are arranged successively in circumferential direction and which are provided at a circumference-side terminating edge, respectively, with fluid delivery surfaces for generating a fluid circulation and are constructed in the form of friction lining segments to produce the frictional interaction with friction linings.

  • Patent number: 7109627
    Abstract: A rotor for an electrical machine includes a rotor carrier of metallic material with a back wall extending radially to the axis of rotation of the electrical machine and a tubular section extending in the axial direction, in which a laminated core is installed. The rotor carrier is designed as a single, flow-formed part with axially extending ribs which engage in grooves on the laminated core.
