摘要： A rotary transmission device for transmitting control and/or working pressures to a wheel hub. The rotary transmission device has a housing structure in which a piston element is displaceable between a first and a second position relative to the housing structure and relative to a running body of the wheel hub which is mounted so as to rotate relative to the housing structure. To transmit the control and/or working pressures, at least one pressure medium channel is formed in the piston element. In the first position, an air gap is present between an end face of the piston element on the running body side and an end face of the running body on the piston element side, while in the second position, no air gap is present, and the at least one pressure medium channel opens in sealed fashion into at least one pressure medium channel formed in the running body.

摘要： A system (40) for transmitting control pressures and/or working pressures from a wheel-hub pressure medium supply (20, 21, 22), in particular from a wheel-hub pressure medium rotary union (21), to a vehicle rim (2) mounted on the wheel hub (1). The system (40) has a receiving part (41), which has a central region (55) with a central opening (44) and at least one extension region (43) projecting radially from the central region (55), at least in some regions. The receiving part (41) can be connected to the wheel hub (1) by means of the at least one radially projecting extension region (43), in a detachable way, and the control pressures and/or working pressures can be transmitted from the wheel-hub pressure medium supply (20, 21, 22) to the opening (44).
