Publication number: 20230286598Abstract: An aerodynamic system may have at least one adjustable aerodynamic element on a leading vehicle. The system may include a sensor device, which is located on the trailing vehicle and is configured to detect status information for the leading vehicle. The system also may include an evaluation unit that is configured to determine a target setting for the aerodynamic element on the basis of respective available settings for the aerodynamic element, the obtained status information, and an optimizing variable. A control unit in the system may be configured to adjust the aerodynamic element to the target setting. A method for controlling the adjustable aerodynamic element may also be included.Type: ApplicationFiled: July 15, 2021Publication date: September 14, 2023Applicant: ZF Friedrichshafen AGInventors: Stefan Beller, Matthias Wesa

Publication number: 20230238861Abstract: A drive unit for an electrically driven vehicle with an inverter module, an electric machine a stator which is controllable by the inverter module. The rotor of the electric machine rotationally drivingly communicates with at least one shaft of the drive unit, the shaft being rotatably supported in a respective associated housing by a bearing arrangement. The housing and the inverter module are grounded. Further, the drive unit has a grounded, low-impedance electrical connection between the shaft and the inverter module so that, when a potential difference occurs between the shaft and the inverter module, a short circuit is produced. Low-impedance potential equalizer is provided between the shaft and the associated housing. It is provided that the shaft is formed as a rotor shaft or as a transmission shaft, the bearing arrangement has two bearings spaced apart axially from one another, and the potential equalizer is formed axially between the two bearings.Type: ApplicationFiled: May 26, 2021Publication date: July 27, 2023Applicant: ZF Friedrichshafen AGInventors: Matthias WESA, Andreas JUNG

Publication number: 20220205522Abstract: A gearwheel (20) for a gear step in an electric vehicle transmission (18) includes a gearwheel carrier and a toothed ring (30) having an external toothing (42). The toothed ring is rotationally fixable to the gearwheel carrier. The gearwheel carrier is formed by a first partial carrier (38) and a second partial carrier (40) that are at least partially axially spaced apart and extend from the toothed ring radially inward. An axial spacing of the two partial carriers is greater, at least partially, than an axial length of the toothed ring.Type: ApplicationFiled: March 4, 2020Publication date: June 30, 2022Inventors: Andreas Jung, Matthias Wesa, Martin Gaber

Patent number: 11331999Abstract: A triple clutch arrangement and a powertrain for a motor vehicle with a dual clutch transmission for use between at least two drive devices and the dual clutch transmission. A first clutch and a second clutch of the triple clutch arrangement are connectable to the first drive device and in each instance to a transmission input shaft. The first drive device and the second drive device are both connected to, or connectable to, a primary side of the first clutch and/or the second clutch via the third clutch.Type: GrantFiled: August 11, 2017Date of Patent: May 17, 2022Assignee: ZF Friedrichshafen AGInventors: Michael Obergasser, Matthias Wesa

Publication number: 20220049757Abstract: A gearwheel arrangement (16) for establishing a gear step in an electric vehicle transmission (17) includes a pinion (22) and an output gearwheel (23). The pinion (22) and the output gearwheel (23) are configured as spur gears and are meshed with each other in order to effect a transmission of a drive power of an electric machine (18). A ratio of a gearwheel diameter to a module of the output gearwheel (23) is in the range from 140 to 350. An electric vehicle transmission (17) with such a gearwheel arrangement (16) and a drive train (15) for an electric vehicle (10) with an electric machine (18), a differential (20), and such an electric vehicle transmission (17) are also provided.Type: ApplicationFiled: November 21, 2019Publication date: February 17, 2022Inventors: Attila Szabo, Matthias Wesa
