  • Publication number: 20260008329
    Abstract: 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.

  • Publication number: 20250381837
    Abstract: 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.

  • Patent number: 11719338
    Abstract: 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.

  • Patent number: 9327691
    Abstract: A transmission parking lock has an actuating rod that is essentially translationally displaceable, which bears an actuating element, and with a locking lever that is essentially rotationally displaceable, bears a locking element For inserting the transmission parking lock through the displacement of the actuating rod, the locking lever is pivotable from a resting position of the same into a locked position in such a manner that the locking element engages in a recess of a gear wheel (8) allocated to a gear shaft, and with a device that withdraws the actuating element of the actuating rod in the resting position of the same from the locking lever.
