Publication number: 20260008329Abstract: A housing arrangement has a first and second housings. The first housing has a connection section on an outer periphery for receiving an electrical connector and a plurality of first fastening sections spaced apart evenly from each other in the peripheral direction for fastening to a second housing. The second housing has a plurality of fastening sections spaced evenly apart from each other in the peripheral direction. The first fastening sections of the first and second housings are arranged in such a way that the first housing can be fastened to the second housing in different angular positions in the peripheral direction. The first housing has at least one transmission section which is formed to correspond to one of the angular positions on a plurality of base sections, where the base sections are designed to form the transmission section corresponding to each of the angular positions.Type: ApplicationFiled: July 7, 2025Publication date: January 8, 2026Applicant: ZF Friedrichshafen AGInventors: Hermann Lanz, Sylva Rother, Mario Holder, Berthold Schraff, Frank Sauter, Horst Leichsenring

Publication number: 20250381837Abstract: A drive unit for a vehicle includes a gearbox having an input element configured to introduce a drive power into the gearbox, and a clutch device with a clutch actuating device. A first drive machine is configured to drive the vehicle and can be mechanically and functionally connected to the input element. A second drive machine is configured to drive the vehicle and can be mechanically and functionally connected to the input element by way of the clutch device. A first housing defines a clutch space for accommodating the clutch actuating device and a drive space for accommodating the first drive machine. Relative to the clutch space, the drive space is arranged in the axial direction offset to a first side. A heat exchanger is arranged radially between an outer circumference of the clutch actuating device and an inner circumference of the first housing inside the clutch space.Type: ApplicationFiled: June 16, 2025Publication date: December 18, 2025Applicant: ZF Friedrichshafen AGInventors: Hermann Lanz, Sylva Rother, Mario Holder, Berthold Schraff, Frank Sauter, Horst Leichsenring

Patent number: 11719338Abstract: A lever (3) for the temporary disengagement of a parking lock (2) of a vehicle drive unit (1). The lever (3) comprises a fixing piece (31) for fitting the lever (3) onto a parking lock shaft (26), which extends inside the vehicle drive unit (1) and serves to actuate the parking lock (2). The lever (3) is a hand lever with a gripping handle (32). The gripping handle (32) is designed to enable a user to apply a manual force for manual actuation of the lever (3). When the lever (3) is fitted on the parking lock shaft (26) and moved, the parking lock shaft (26) is moved from an engagement position to a disengagement position. In the disengagement position, by further movement of the gripping handle (32) into a locking position, the lever (3) is blocked against a reverse movement out of the disengagement position.Type: GrantFiled: July 30, 2021Date of Patent: August 8, 2023Assignee: ZF Friedrichshafen AGInventors: Berthold Schraff, Horst Leichsenring, Frank Sauter, Andreas Jauch, Armin Gierling
