    摘要: The present disclosure provides a hitch suspension system that reduces a transfer of energy (e.g., provides a smoother ride) between two bodies hitched together, such as between a towing vehicle and a towed vehicle/trailer. In an embodiment, the suspension system includes a hydraulic cylinder with an extendable rod in fluid communication with a fluid pump. A control valve is fluidly coupled between the hydraulic cylinder and the fluid pump and is configured to adjust an extension length of the rod. Additionally, a variable orifice that adjusts resistance to extension and retraction of the rod is fluidly coupled between the hydraulic cylinder and the control valve. A first fixed restrictive element is fluidly coupled in series with the variable orifice to dissipate energy ad the rod extends and a second fixed restrictive element is fluidly coupled in series with the variable orifice to dissipate energy as the rod retracts.

    摘要: A hydraulic circuit is disclosed. The hydraulic circuit may have a variable displacement pump. The variable displacement pump may have a fluidic displacement control configured to vary a flow of pressurized fluid based on a fluid signal and an electronic displacement control configured to vary the flow of pressurized fluid based on an electronic signal. The flow of pressurized fluid may be controlled by the one of the fluidic and electronic displacement controls that requests the smallest flow of pressurized fluid. The hydraulic circuit may also have a control valve connected between the pump and the fluidic displacement control, and the control valve may be configured to transmit the fluid signal to the fluidic displacement control. The hydraulic circuit may further have a controller configured to transmit a fluid signal to cause the fluidic control to request a maximum flow of pressurized fluid, and transmit an electronic signal requesting a flow smaller than the maximum flow, which causes the electronic displacement control to vary the flow of pressurized fluid.

The hydraulic system may also have a second actuator connected to the first pump in parallel with the first actuator via the first circuit, and a second switching valve disposed between the second actuator and the first pump. The second switching valve may be configured to control a fluid flow direction through the second actuator. The hydraulic system may further have a modulation valve associated with the first circuit and configured to selectively modulate a pressure of the first circuit during actuation of the first or second switching valves.
