Patent number: 11865908Abstract: A dual transmission with input shafts, output shafts, a transmission case and two separate single transmissions arranged in the transmission case is described. Each single transmission is a two-stage spur gear transmission with three positions for gear centers. A first position is occupied by an input shaft and a second position by an output shaft. A third position is for a middle stationary axle fixed to the transmission case. The three positions define a triangular arrangement having a first side defined by a distance between the first position and the second position, a second side defined by a distance between the first position and the third position, and a third side defined by a distance between the second position and the third position. The second side and the third side form respective angles with the first side. At least one of these angles has a value ranging between 5° and 70°.Type: GrantFiled: July 9, 2020Date of Patent: January 9, 2024Assignee: HOFER POWERTRAIN INNOVATION GMBHInventors: Mathias Lutz, Klaus Kalmbach, Markus Lee, Fabian Kelch

Patent number: 10569637Abstract: A drive system for a hybrid vehicle having an internal combustion engine includes an electric motor and a clutch device which has a frictional locking element and a positive locking element that is connected parallel to the frictional locking element. The clutch device is configured to couple the internal combustion engine into the drive system and to be switched into at least the following states: a) open positive locking element and closed frictional locking element when starting and/or synchronization of the internal combustion engine, b) closed positive locking element and closed frictional locking element or closed positive locking element and open frictional locking element when the internal combustion engine is running and synchronized such that an internal combustion engine drive output action is generated, and c) open positive locking element and open frictional locking element when the internal combustion engine is stopped such that purely electric motor drive of the vehicle is provided.Type: GrantFiled: August 3, 2017Date of Patent: February 25, 2020Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Dirk Aringsmann, Daniel Mooz, Klaus Kalmbach

Patent number: 9267595Abstract: A drive device for a motor vehicle includes at least one electric machine having at least one rotor element which is configured to delimit an installation area in a radial direction. At least one transmission device is disposed, at least partly, in the installation area and configured to be driven by the electric machine via the rotor element. A fluid supply device having at least one fluid channel is provided for supply of fluid to at least one cooling or lubrication point of the drive device. The fluid channel has a first part area running in a stationary first component, and a second part area which adjoins the first part area in a flow direction of the fluid through the fluid channel and runs in a second component of the drive device. The second component is supported for rotation about an axis of rotation in relation to the first component.Type: GrantFiled: April 15, 2013Date of Patent: February 23, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Klaus Kalmbach, Klaus Schleicher, Janina Steinz
