The invention relates to an assembly including a hydraulic apparatus having a rotor and a stator. The rotor is mounted so as to turn about a second rotation axis with respect to the stator and is secured to a device suitable for mounting a vehicle wheel. A pivot-pin element is intended to be mounted on an axle and is mounted so as to rotate about a first rotation axis with respect to the hydraulic apparatus. The stator is mounted so as to turn about the first rotation axis with respect to the axle. An air chamber is formed between the pivot-pin element and the hydraulic apparatus, the air chamber is connected to a distribution passage formed in the hydraulic apparatus. An axle passage is formed in the pivot-pin element so as to form a pneumatic passage between the pivot-pin element and the hydraulic apparatus.
An assembly comprising a hydraulic apparatus which comprises a rotor and a stator, the rotor being rotatably mounted relative to the stator along a second axis of rotation, and being secured to a spindle for mounting of a vehicle wheel,
