An assembly including Views along a plane defined by the second axis of rotation and the first axis of rotation, the proximal rolling-element bearing and the distal rolling-element bearing are positioned on either side of the first axis of rotation, in that the cylinder block is positioned between the first axis of rotation and the proximal rolling-element bearing.

Hydraulic motor for a vehicle steered wheel

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.
