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: A hydraulic transmission apparatus having at least one declutchable hydraulic motor having radial pistons and connected via two motor ducts, and a casing duct connected to the inside of the casing. The apparatus further has clutching means that, in order to perform the clutching of the motor, are suitable for bringing a first one of the motor ducts to a “clutching” first pressure that is higher than the pressure in the casing while also making it possible to remove fluid via the casing duct. Disposed on the casing duct, the apparatus further has means for limiting the flow of fluid in said casing duct, in a manner such as to cause the pressure inside the casing to increase during the clutching operation. This apparatus enables clutching to take place gently.

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.

摘要: The invention relates to a flow control valve adapted for use as a flow-dividing and flow-combining valve in hydraulic devices, comprising: a valve body having a first longitudinally extending bore, an outer spool slidably positioned within the bore, the outer spool having an axially extending passageway, a pair of axially extending inner spools slidably positioned within the passageway, the valve body having a first port and a pair of second ports, the outer spool having at least a first opening communicating with the first port and with the passageway, and at least two pairs of second openings therethrough. At least one second opening of each pair is of non-constant longitudinal section narrowing from the outer face of the outer spool on at least a part of the thickness of the second opening, so that a lateral side of the second opening offers an obstacle where a part of the fluid flow entering the second opening crashes before entering the inner spool.
