ROTARY TRANSMISSION FOR A VEHICLE WHEEL Russian patent published in 2018 - IPC B60C23/00 B60B27/00 

FIELD: motor industry.

SUBSTANCE: rotary transmission for a vehicle wheel with tire pressure regulation includes a wheel bearing device and a wheel mounted in the bearings on the wheel carrier, with the possibility of rotation of the wheel hub. In the intermediate space between the wheel carrier and the wheel hub, an annular chamber for compressed air and at least an annular chamber for the lubricant are formed, which are sealed against each other. In this case, the annular chamber for compressed air communicates with a channel for compressed air of the wheel carrier and with the channel for compressed air of the wheel hub, wherein the compressed air channel of the wheel hub communicates with the controllable valve to optionally fill the tire of the truck wheel with compressed air or discharge compressed air therefrom. Annular chamber for the lubricant is again communicated with the lubricant channel of the wheel carrier and with the lubrication channel of the wheel hub, the channel for the wheel hub lubricant leads to the connection of the control line of the valve, so as to optionally adjust the valve for passing compressed air.

EFFECT: reduction of the level of wear of the rotating joint for simplicity and compactness of its construction.
