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： An operator interface assembly for a machine includes a base, an operator input device, a first biasing member, and a second biasing member. The operator input device is operable to move in a direction in relation to the base. The first biasing member is operable to contact the operator input device at a first position and resist movement of the operator input device in the direction. The second biasing member is operable to contact the operator input device at a second position and resist movement of the operator input device in the direction.

摘要： A hydraulic system includes a fluid source, a metering valve, an actuator, and a power reclamation assembly. The metering valve includes a standby position, and an actuation position different than the standby position. The metering valve fluidly connects the actuator to the fluid source when in the actuation position. The metering valve fluidly connects the power reclamation assembly to the fluid source when the metering valve is in the standby position.
