摘要： The present invention relates to a driver self-tuning method using an electro-hydraulic actuator system, the method comprising: a step in which a specific EHA system is selected by a HMI; a step of displaying a graph defining the mapping relationship of an actuator speed command with respect to a joystick command of the selected EHA system; a step in which, when a predetermined button is pressed by a user, the actuator maximum speed is tuned by multiplying the maximum speed value of the actuator of the selected EHA system, which has been pre-stored, by gain that increases or decreases in proportion to the number of times the button was pressed; and a step of storing the tuned actuator maximum speed in the upper controller of the EHA system. Equipment using the electro-hydraulic actuator system makes it possible to directly tune actuator speed characteristics that cannot be achieved with existing equipment using, by way of example, HMI display equipment and operating buttons.

摘要： Apparatuses and systems that use a variable displacement motor-pump (VDMP) to control the position and speed of a hose for an aerial refueling system are disclosed. At displacements greater than required to hold a position of the hose, the VDMP operates in a motor mode to retract the hose. For lesser displacements, the VDMP operates in a pump mode to control extension of the hose. In accordance with some embodiments, a pump-motor relief valve operates to throttle hydraulic fluid flow from the VDMP and to control mixing of hydraulic fluid flowing from the VDMP with system hydraulic fluid.

摘要： The present disclosure refers to a hydrostatic drive system for a vehicle (10), which may comprises an open circuit a closed circuit (120), and a combiner valve (118). The open circuit (100) may include a main hydraulic pump (102) configured to be driven by an internal combustion engine (12), and configured to drive at least one hydraulic consumer (34, 44, 50). The closed circuit (120) may include an auxiliary hydraulic pump (170) configured to travel the vehicle (10), and an hydraulic motor (146) connected to the auxiliary hydraulic pump (170). A pressure-relief valve (164) is sized and configured to drain the hydraulic fluid circulating within the closed circuit (120) and exceeding the maximum capacity of the auxiliary pump (170) to a reservoir (300) even if hydraulic fluid is diverted from the open circuit (100) into the closed circuit (120). The combiner valve (118) is connected to both the open circuit (100) and the closed circuit (120). The combiner valve (118) may be configured to connect the open circuit (100) to the closed hydraulic circuit (120) such that a part of the hydraulic fluid circulating in the open circuit (100) is diverted into the closed circuit (120). The present disclosure also refers to a method of operating a vehicle (10).

摘要： A hydraulic drive system for an actuator uses a pair of pressure compensated hydraulic machines to control flow to and from the drive chambers of the actuator by varying the controlled pressure of one of the machines. The machines are mechanically coupled to permit energy recovery and charge an accumulator to store supplies energy. The drive system may be combined with other services including a transmission for incorporation in a vehicle. The transmission uses a pressure compensated supply and torque control of the wheels.
