Abstract: A tool for transferring a motor vehicle into a rollable state despite a parking lock having been activated includes a base which is fastenable to a vehicle wheel of the motor vehicle and an actuating element which is displaceable along a sliding direction relative to the base and via which, in a state of the base fastened to the vehicle wheel, by displacement of the actuating element along the sliding direction relative to the base, displacing a propeller shaft of the motor vehicle, a toothing engagement between a first toothing of the propeller shaft and a second toothing of a wheel hub can be undone, as a result of which the motor vehicle can be transferred into the rollable state. A travel limiting device specifies a travel by which the actuating element can be displaced at most relative to the base in order to undo the toothing engagement.

Abstract: A transmission assembly has a transmission housing, a hinged support and a transfer case which form separate structural units. The transmission housing includes at least one common connection point by which the hinged support and the transfer case are jointly coupled to the transmission housing.

Abstract: A coiled heat exchanger having a plurality of tubes, which are helically coiled around a core tube in one or more concentric layers of tubes and form a bundle in the form of a hollow cylinder, and also having a shell, which delimits an outer space around the tubes, is disclosed. It is formed in such a way that, during operation, heat is transferred between at least two fluid streams, one of which flows through the interior of the tubes and the other of which flows through the outer space. At least one elastic component that does not transfer heat and comprises a metallic material is arranged inside the shell and radially outside the bundle.
