Patent number: 8641568Abstract: An electric machine arrangement for an electric axle of a motor vehicle has an electric machine. The electric machine is connected via a gearbox to at least one drive shaft which can be connected to a driven wheel of the motor vehicle. Further, the machine arrangement has a machine housing. The electric machine has a stator fixed to the housing and a rotor which is connected to an input element of the gearbox. The rotor is rotatably mounted on the machine housing by a first and a second rotor bearing section. The first rotor bearing section is connected to a machine output shaft which is connected to the input element of the gearbox. The machine output shaft is guided through the second rotor bearing section in a contactless fashion.Type: GrantFiled: April 18, 2012Date of Patent: February 4, 2014Assignee: GETRAG Getriebe- und Zahnradfabrik Hermann Hagenmayer GmbH & Cie KGInventors: Daniel Knoblauch, Ulrich Knoedel

Patent number: 8403088Abstract: An electric axle drive unit for an axle of a vehicle has an electric machine. The drive output of electric machine can be connected to the input of a transmission device. The electric drive unit has a differential gear, the input member of which is connected to an output of the transmission device. The output members of the differential gear can be connected respectively to a left-hand and a right-hand driveshaft of the axle. At least one transmission stage of the transmission device and the differential gear are arranged on opposite sides of the electric machine in the axial direction. The differential gear is connected to the transmission stage by means of a hollow shaft.Type: GrantFiled: March 12, 2009Date of Patent: March 26, 2013Assignee: GETRAG Getriebe-und Zahnradfabrik Hermann Hagenmeyer GmbH & Cie KGInventors: Daniel Knoblauch, Alexander Kreim, Ulrich Knoedel

Patent number: 8344565Abstract: An actuator arrangement for the axial displacement of an actuation member by means of a drive force which is generated by an electric machine, in particular for a shift-clutch arrangement of a multi-step gear change transmission. The actuation member is mounted axially displaceably on a rotary shaft. The electric machine has a stator fixed to a housing and a rotor which is coupled to the actuation member and is arranged coaxially with respect to the actuation member. The rotor is coupled to the actuation member with a form fit in the axial direction. Here, the rotor or the actuation member has a radial projection which engages into a radial groove of the other part.Type: GrantFiled: September 3, 2008Date of Patent: January 1, 2013Assignee: GETRAG Getriebe- und Zahnradfabrik Hermann Hagenmeyer GmbH & Cie KGInventors: Mark Schweiher, Uli Christian Blessing, Thorsten Gatzka, Ulrich Knoedel

Patent number: 7884518Abstract: An electrical synchronous machine, in particular for use as a drive machine in motor vehicle applications. A stator has an electrical winding arrangement for generating a rotating field. A rotor has magnetic flux generating means for generating a rotor flux with which the rotating field interacts. The rotor has a first rotor section with first magnetic flux generating means and a second rotor section with magnetic flux influencing means. It is possible to move the two rotor sections relative to one another between at least a first and a second relative position in such a way that the rotor flux provided by the rotor has a different magnitude in the two relative positions.Type: GrantFiled: December 1, 2008Date of Patent: February 8, 2011Assignee: GETRAG Getriebe- und Zahnradfabrik Hermann Hagenmeyer GmbH & Cie KGInventors: Uli Christian Blessing, Alexander Kreim, Ulrich Knoedel, Matthias Beck
