Patent number: 11588379Abstract: A temperature control arrangement (1) of a motor vehicle has an electric machine (2) with a rotor (3) and a stator (4), a stator cooling arrangement with a first cooling circuit (6) for cooling the stator (4) with a first cooling medium (8) flowing in the first cooling circuit (6) that is formed by a motor vehicle cooling circuit, a rotor cooling arrangement with a second cooling circuit (7) for cooling the rotor (3) with a second cooling medium (9) flowing in the second cooling circuit (7) that is formed by a transmission oil cooling circuit, a heat exchanger (10) that thermally couples the first cooling circuit (6) and the second cooling circuit (7). The stator cooling arrangement is configured such that the first cooling medium (8) makes direct contact with the stator windings.Type: GrantFiled: July 1, 2020Date of Patent: February 21, 2023Assignee: Dr. ing. h. c. F. Porsche AGInventors: Janina Steinz, Stefan Oechslen

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
