Claim 18:
19. 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 receives at least a portion of the rim insert arranged in a central bore of the vehicle rim, and
wherein the opening is rotationally symmetrical and has an inner circumferential surface; in the inner circumferential surface, at least one annular region is formed, which runs all the way around and is embodied in such a way that the control pressures and/or working pressures can be transmitted from the wheel-hub pressure medium supply to the at least one annular region by way of the at least one radially projecting extension region.
