Patent number: 11715984Abstract: An electric machine has a plurality of phases. A winding is associated with each phase. An interconnection arrangement includes an annular carrier element with a plurality of axial cutouts, each for passage of a portion of a winding and a plurality of concentrically arranged, hollow-cylindrical switching rings. Each switching ring is adapted to contact a winding. The carrier element and the switching rings are adapted to radially positively engage one inside the other in an axial contact zone.Type: GrantFiled: August 27, 2018Date of Patent: August 1, 2023Assignee: ZF FRIEDRICHSHAFEN AGInventors: Katja Willacker, Christoph Wieder, Jochen Wittmann, Roland Lindwurm, Ralf Wittstadt, Daniel Schmitt, Matthias Cudok, Bernhard Byzio, Alexander Schäflein, Marcus Van Heyden

Publication number: 20220014067Abstract: An interconnection for an electric machine with hairpin winding, having a plurality of connection pins, the interconnection includes connection conductors that extend over a portion of the circumference in each instance. The interconnection has a carrier that supports the connection conductors and insulates the connection conductors relative to one another. Each connection pin is electrically conductively connected to a connection conductor. The carrier has supporting arms at the outer circumference thereof, in that the supporting arms are inclined relative to a radially extending plane as well as relative to a rotational axis of the electric machine, and the supporting arms have clamping surfaces by which they are clampable between a housing or stator carrier and a bearing shield.Type: ApplicationFiled: September 25, 2019Publication date: January 13, 2022Inventors: Jochen WITTMANN, Christoph WIEDER, Matthias CUDOK

Patent number: 10465790Abstract: A torque transmission arrangement, particularly for an arrangement with an electric machine in a drive module of a hybrid vehicle or electric vehicle, for transmitting a torque from an output shaft, particularly a motor output shaft, to a drive shaft, particularly a transmission input shaft. The drive shaft further has at least one fluid guide channel in which a fluid can be guided in direction of the output shaft. A fluid-carrying element which guides fluid out of the fluid guide channel of the drive shaft into a radially outer region of the output shaft and is provided at the output shaft.Type: GrantFiled: March 12, 2015Date of Patent: November 5, 2019Assignee: ZF Friedrichshafen AGInventors: Matthias Cudok, Klaus Reuter, Tomas Vnuk

Patent number: 10436259Abstract: An axially actuatable positive engagement clutch which includes an input shaft with an input toothing and an output shaft with an output toothing. An axially displaceable connection element can occupy a meshing position which is located in an actuation path (s) between the open position and the closed position and in which the driving toothing engages with the input toothing or the output toothing for the first time during the transition from the open position into the closed position. An actuation device is configured to displace the connection element from the closed position to the open position, and an elastic return element which applies a restoring force to the connection element in direction of the closed position. The return element has a force/deflection characteristic with a local force maximum (F1) which coincides in the actuation path (s) at least approximately with the meshing position of the connection element.Type: GrantFiled: November 8, 2016Date of Patent: October 8, 2019Assignee: ZF Friedrichshafen AGInventors: Martin Ruider, Michael Pantke, Johannes Winkler, Matthias Cudok, Martin Hain, Alexander Markow

Patent number: 9318929Abstract: An electric machine has a stator which carries a polyphase coil winding, wherein coil ends are connected in a predetermined manner to a plurality of electric connection conductors. The electric machine comprises a power connection unit having a plurality of terminal conductors which are constructed separate from the connection conductors and which by a first end portion are bondingly connected or connectable to the connection conductors and by a second end portion are connected or connectable to the electrical energy source. The power connection unit is constructed as a plastic composite element, in which the terminal conductors are embedded at least over a portion of their length in a plastic shell so as to be spaced apart from one another, and wherein first end portions of the terminal conductors project out of the plastic shell.Type: GrantFiled: May 22, 2012Date of Patent: April 19, 2016Assignee: ZF Friedrichshafen AGInventors: Alexander Schäflein, Matthias Weidner, Udo Niehaus, Matthias Cudok, Christian Brückner, Stefan Keller
