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 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.

Steering pivot pin forming an internal pneumatic passage

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.

Hydraulic device comprising an air flow line

The arrangement comprises a hydraulic machine with at least two operating cylinders, the hydraulic machine comprising a rotor part configured to be connected to the steered wheel and a stator part having main enclosures open in a receiving interface, and a pivot device that defines a pivot axis of the stator part and has main outer orifices linked to the main enclosures of the hydraulic machine in a connection interface. The arrangement further comprises a pilot line linked to a pilot chamber which has a pilot inlet in the receiving interface and the pilot line is formed in the pivot device and extends between an outer pilot orifice present in this device and a pilot opening located in the connection interface.

Hydraulic arrangement for a steered wheel of a vehicle

The invention relates to a system for pneumatically powering a wheel comprising a bearing support (), a shaft () comprising a hub-forming end () which extends radially (Y), at least one set of rolling bearings (), wherein the system further comprises a chamber (C) formed by the hub-forming end (), the bearing support (), a rolling bearing seal () and a chamber seal (), a primary channel () crossing the bearing support () and opening into the chamber (C), a secondary channel () crossing the hub-forming end () and opening into the chamber (C), wherein seals seal the cavity (C) in order to let air pass from the primary channel to the secondary channel via the cavity (C).
