Mechanically driven tire pressure generation means
First Claim
1. A wheel hub arrangement having a wheel hub for mounting a rim of the wheel hub arrangement with an inflatable tire, the wheel hub arrangement comprising:
- a rotary piston compressor that is mounted rotatably on the wheel hub,the rotary piston compressor being configured to be switched over between a compression mode, in which the rotary piston compressor is configured to be actuated by way of a rotational movement relative to the mounted rim or the wheel hub, and a rest mode, in which the rotary piston compressor is passive and does not produce any compressed air, andwherein the rotary piston compressor produces compressed air for filling the tire in the compression mode,wherein the wheel hub arrangement has a tire sealant reservoir which is arranged and configured in such a way that a tire sealant can be fed into the compressed air which is produced by the rotary piston compressor.

Abstract
A wheel hub arrangement having a wheel hub for mounting a rim with an inflated tire. The wheel hub arrangement has a rotary piston compressor mounted rotatably on the wheel hub. The wheel hub arrangement has a switchable mechanical coupling device, by way of which the rotary piston compressor can be switched over between a compression mode, in which the rotary piston compressor can be actuated by way of a rotational movement relative to the mounted rim or the wheel hub, and a rest mode, in which it is passive and does not produce any compressed air on the outlet side, and the rotary piston compressor producing compressed air on the outlet side for filling the tire in the compression mode.
