The rotating hydraulic machine () comprises: —a housing (), —a shaft () movably mounted relative to the housing about an axis, —an apron () rigidly connected to the shaft and extending around at least a portion of the housing, —a cam () rigidly connected to either the housing or the shaft, —a cylinder block () rotationally connected to the other of either the housing or the shaft, the cylinder block comprising pistons capable of engaging with the cam to produce a relative rotation between the shaft and the housing, —first and second guide bearings () each bearing directly on the housing and the apron, and —at least a third guide bearing () bearing directly on the housing and the cylinder block.

Hydraulic machine comprising bearings for supporting the rotating component

A hydraulic machine has a first assembly and a second assembly movable in rotation relative to each other about an axis of rotation. The first assembly and the second assembly define an internal volume and are in contact along an interface. The interface between the first assembly and the second assembly is provided with a sealing element positioned in a housing connected to the internal volume via a first duct, and to the surrounding environment via a second duct. The first duct is provided with a sealing element adapted to isolate the housing from the internal volume, where a secondary cavity is formed in the first assembly or in the second assembly. The secondary cavity is connected to the housing and isolated from the internal volume.

Lubrication for hydraulic machine seal

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 present invention relates to a hydraulic device () with radial pistons, comprising:
