摘要： A single motor for servicing both an auxiliary circuit and a boost circuit of a regenerative hydraulic system. The hydraulic system includes at least one hydraulic pump that collectively or singly supplies hydraulic fluid to one or more hydraulic motors for an auxiliary function and to a fluid communication line selectively in fluid communication with a port of a hydraulic pump for boost, and a single auxiliary electric motor for driving the at least one hydraulic pump. By driving the two circuits independently using the single electric motor, overall cost of the hydraulic system is reduced and additional components such as another electric motor and inverter are eliminated.

摘要： A hydraulic system includes one or more hydraulic subsystems that have a source of additional flow for supplying an auxiliary system. The hydraulic system may include one or more actuator systems, a boost system, and a further hydraulic system, such as a steering system. The source of additional flow for supplying the auxiliary system may include: sizing the boost system for providing both full boost function and auxiliary function, sizing the steering system for providing both full steering function and auxiliary function, utilizing available flow from an unused actuator function, and/or utilizing a selector manifold for actively selecting the source of auxiliary flow based on the flow and pressure demands of the respective hydraulic systems. Such a hydraulic system enables flow to be available to an auxiliary function regardless of the flow requirements for the actuator functions and/or other vehicle functions, while also minimizing interactions and flow disruptions to the various hydraulic subsystems.

摘要： An electro-hydraulic actuation system includes a regeneration valve in fluid communication with a first fluid chamber and a second fluid chamber of a hydraulic actuator, and a dump valve is in fluid communication with the second fluid chamber and a fluid reservoir. A pump provides a flow of fluid to the first and second fluid chambers, a displacement of the pump controlling a velocity of the actuator during motion in the retraction and extension directions. An electric motor drives the pump, and a controller controls a state of the regeneration valve and the dump valve. At least one feedback device senses a system condition and provides a respective feedback signal indicative of the sensed system condition to the controller, the controller responsive to the feedback signal to determine an occurrence of an over-center load condition and control a state of the regeneration valve and the dump valve in response to the occurrence to maintain the velocity of the actuator.

摘要： Presented is a system and method to control hydraulic fluid flow, more specifically throttle hydraulic fluid flow, to achieve actuator deceleration rates greater than the maximum deceleration rate of an electrically driven pump. Electric machines and electric machine inverters generally have a maximum torque and current limit beyond which they cannot be operated at. To decelerate a large inertia load for example, high electric machine torque and inverter current are required to provide the braking torque, opposing the fluid flow and pressure generated by the load and hydraulic system.

摘要： An electro-hydraulic actuation system (901) includes an unbalanced hydraulic actuator (902) capable of motion in retraction and extension directions during movement of a load (904). A pump (204) provides a flow of fluid to the actuator. A displacement of the pump controls a velocity of the actuator during motion in the retraction and extension directions. An electric motor (202) drives the pump. Speed and direction of the electric motor affects the displacement of the pump. A controller (802) controls the speed and direction of the electric motor. A feedback device (228,248) is operable for sensing a system condition and for providing a feedback signal indicative of the sensed system condition to the controller. The controller is responsive to the feedback signal for determining an occurrence of an over- center load condition and for modifying the speed of the electric motor in response to the occurrence in an attempt to maintain the velocity of the actuator.
