摘要： 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.

摘要： A braking device may include a brake casing rotatably assembled with respect to a shaft along an axis of rotation, first braking elements and second braking elements, forming a stack, an elastic return element configured to exert an application force on the first and second braking elements, and a brake release actuator, adapted to bias the elastic return element along a direction opposing the application direction. The braking device a may include a diffusion wedge and a pressure wedge positioned respectively to bear against the stack and against the elastic return element. The diffusion wedge and the pressure wedge may have contact surfaces defining an annular linear contact about the axis of rotation.

摘要： An emergency braking device including an actuator (2), a pressurizing circuit (3) supplying the actuator (2) via a control pressure and a discharge circuit (4). The discharge circuit (4) includes restrictors (13, 14) for controlling the pressure and/or flow rate of the supply fluid of the actuator (2) during a discharge of the actuator. The restrictors (13, 14) are configured to define an intermediate pressure between a low pressure level and the control pressure of the actuator (2).

摘要： The invention relates to a pressure-limiting device designed to be installed in a system comprising a first line (11) and a second line (12) that can comprise pressurised oil, as well as comprising a discharge and/or booster line (10). The device also comprises a pressure selector (130, 150) in the form of a cage defining two seats (132, 134) and two pressure relief valves (160, 180). The limiting device is characterised in that it further comprises at least one means (170, 172; 190, 192) for regulating a pressure relief valve, disposed on the outside of an axial end of the pressure selector (150), in the form of a cage that allows the loading of the associated pressure relief valve to be regulated.

摘要： A vehicle including a driving axle (10), a driven axle (20), a hydraulic pump (14) and a hydraulic motor (24) providing hydraulic assistance for driving the driven axle (20) by lapping off torque applied to the driving axle (10). The driving axle (10) comprising includes a differential (11) 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 (14) 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 (11). The hydraulic pumps (14) are rotationally driven at a speed equal to the average speed of the two half axles associated with the differential (11) on which the pump is mounted.
