Said arrangements consist of an adapter provided with fixing boreholes for fixing the brake disk and provided with an inner profile ( ) which, on the wheel hub sleeve ( ), can be connected in a rotationally fixed manner to a profile which is arranged on the wheel hub sleeve in a rotative manner and which is adapted to the inner profile. The invention is advantageous in that a universal wheel hub sleeve is produced which can be equipped either with or without a brake disk on which, however, the rotating part of another type of brake device can be applied.
