The hydraulic machine includes a cam and a cylinder block with pistons co-operating with cam lobes, each of which has two ramps extending between top and bottom dead center arcs. The cylinders are connected in alternation to a feed and to a discharge, in sequences separated by switchover stages including an isolation stage during which they are isolated relative to the feed and discharge main ducts. The angular position of the start or of the end of at least one first isolation stage relative to the corresponding dead center arc is different from the angular position of the start or of the end of at least one second isolation stage relative to its corresponding dead center arc, both of these dead center arcs being top dead center arcs or both of them being bottom dead center arcs.

Harmonic distribution radial piston hydraulic machine

A vehicle including a driving axle (), a driven axle (), a hydraulic pump () and a hydraulic motor () providing hydraulic assistance for driving the driven axle () by lapping off torque applied to the driving axle (). The driving axle () comprising includes a differential () thus defining two output half axles on which wheels are mounted. Rotation of the box allows the output half axles to be rotationally driven at distinct speeds. The hydraulic pump () includes a rotor and a stator, the stator being mounted fixed with respect to the chassis and the rotor being connected to and rotating as one with the differential box (). The hydraulic pumps () are rotationally driven at a speed equal to the average speed of the two half axles associated with the differential () on which the pump is mounted.

A hydraulic apparatus including a machine shaft having a proximal end and a distal end, adapted to drive a cylinder block. A clutch having a clutch shaft having a proximal end and a distal end, and a plurality of friction discs linked to the distal end of the clutch shaft and a plurality of friction discs linked to the proximal end of the machine shaft for selectively engaging the clutch shaft with the machine shaft. The friction discs are disposed radially around the machine shaft. The distal end of the clutch shaft is bell-shaped so as to surround the proximal end of the machine shaft. The bell shape defines an inner space where the proximal end of the machine shaft and the friction discs linked to the clutch shaft are located.
