Abstract
The invention relates to a hydraulic device including: a stator and a rotor, in which the rotor can rotate relative to the stator about a first axis of rotation; and a shaft mounted on the rotor such as to rotate therewith. The shaft has a wheel carrier provided at a proximal end thereof and designed to receive a rim and a tire. The shaft includes a through-channel extending from the proximal end to an opposing distal end. The hydraulic device includes an air chamber formed at the distal end of the shaft and connected to the through-channel. The through-channel and air chamber are produced such as to allow a flow of air in order to control the pressure of a tire.

A hydraulic apparatus comprising a stator and a rotor, the rotor being movable in rotation relative to the stator along a first axis of rotation,
- a shaft mounted secured in rotation to the rotor, the shaft having a wheel carrier arranged at a proximal end, and configured to receive a rim and a tire,
- wherein the shaft has a through channel from the proximal end to an opposite distal end, and
- wherein the hydraulic apparatus comprises an air chamber formed at the distal end of the shaft and connected to the through channel, with the through channel and the air chamber made so to allow an air circulation in order to control the pressure of a tire.
