Patent number: 7952255Abstract: 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.Type: GrantFiled: March 10, 2009Date of Patent: May 31, 2011Assignee: ZF Friedrichshafen AGInventors: Khalid Jafoui, Alexander Schäflein

Patent number: 7514828Abstract: 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.Type: GrantFiled: March 16, 2006Date of Patent: April 7, 2009Assignee: ZF Friedrichshafen AGInventors: Alfons Vollmuth, Khalid Jafoui, Marcus van Heyden

Patent number: 7216750Abstract: 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.Type: GrantFiled: July 5, 2003Date of Patent: May 15, 2007Assignee: ZF Sachs AGInventors: Jörg Sudau, Khalid Jafoui, Jürgen Ackermann
