摘要： A hydraulic actuator comprises piston that divides the interior into a piston chamber and a rod chamber and a valve disc assembly to regulate flow of hydraulic fluid between the piston chamber and the rod chamber through a passage in the piston. The disc valve assembly includes a washer, a valve pack that includes at least one flexible disc valve, and a spacer arrangement spacing the valve pack apart from the washer. During operation, the valve pack flexes to open and close the passage. The spacer arrangement includes a first support point supporting the valve pack relative to the washer and at least one second support point spaced apart from the flexible portion of the disc valve pack. In the open position, the valve pack engages the second support point to reduce stress build-up at the first support point, thereby reducing work fatigue of the valve disc and extending the useful life of the hydraulic actuator.

摘要： A vehicle has a real time suspension control which requires, as inputs, a set of absolute body modal velocity signals. Accurate estimates of these signals are derived from relative position sensors at the body suspension points by converting the relative vertical position signals from these sensors to relative body modal (e.g. heave, pitch and roll) velocity signals and passing each of these signals through a second order low pass filter including an additional phase inversion for compensation of the 180 degree filter phase lag. Thus, the necessity of absolute body accelerometers is eliminated, for a significant cost reduction. In a vehicle having significant front to rear flexing or flexing within the front or rear suspension that can affect the accuracy of the estimated absolute body roll velocity, the normal roll velocity transformation equation is modified to include only the front or the rear pair of relative velocity signals.

摘要： A suspension for a motor vehicle comprises a control arm connected to each of a pair of wheels, a torsion bar, and a height actuator. The torsion bar is connected to each control arm, and is rotatable in first and second directions. The height actuator is connected between the torsion bars, and is operable to lower a sprung mass of the vehicle by rotating the torsion bars in the first directions, and to raise the sprung mass by rotating the torsion bars in the second directions. A roll actuator is also connected between the height actuator and the sprung mass.

摘要： A hydraulic system for use in a motorized vehicle including a pressure source, a valve fluidly coupled to the pressure source, and an actuator fluidly coupled to the valve. The actuator includes an outer casing and a piston slidably received in the outer casing such that the piston defines a piston chamber and a rod chamber in the outer casing. The actuator includes a rod coupled to the piston on a side of the piston facing the rod chamber. The valve is configured such that when the valve is in an open position the valve provides fluid communication to the rod chamber and provides fluid communication to the piston chamber. Fluid flowing through the valve to the rod chamber passes through a restricted orifice having cross sectional area that is smaller than the cross sectional area of any orifice that would be passed through by fluid flowing through the valve to the piston chamber.
