System for transmitting control pressures and/or working pressures

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;
• 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 rim insert has an outer circumferential surface including at least one annular region that extends around and in a state that, when the rim insert is accommodated by the opening of the central region, control pressures and/or working pressures can be transmitted from the hub pressure medium supply to the at least one annular region by way of the at least one radially projecting extension region;
• wherein the at least one radially projecting extension region includes a pressure medium channel with a first end region in fluid connection with a pressure medium connection of the extension region, and a second end region open toward the at least one annular region;
• wherein the pressure medium connection of the at least one extension region is embodied as a plug-in connection and is designed to be accommodated in a counterpart connection through a brake-disc chamber that is positioned at least partially between the wheel hub and the vehicle rim and opens out into a line system that is in or can be brought into fluid connection with the wheel-hub pressure medium supply.

• 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.
