1. A system for transmitting control pressures and/or working pressures from a wheel-hub pressure medium rotary union of a wheel-hub pressure medium supply, to a vehicle rim mounted on a wheel hub, the system comprising:
a receiving part, which includes a central region with a central opening and at least one extension region projecting radially from the central region, wherein the receiving part is connectable to the wheel hub by the at least one radially projecting extension region, in a detachable way; and
a rim insert configured to attach to the vehicle rim and to record and/or export control pressures and/or working pressures, and which is accommodated by the central opening, and the control pressures and/or working pressures are transmittable from the wheel-hub pressure medium supply via the receiving part to the rim insert,
wherein:
the opening of the central region has an inner circumferential surface including a first annular groove or annular region;
the rim insert has an outer circumferential surface including a second annular groove or annular region; and
when the rim insert is inserted into the opening the first annular grove or annular region is aligned with the second annular groove or annular region to transmit the control pressures and/or working pressures between the receiving part and the rim insert.
