摘要： A method and apparatus for dynamically leveling the attitude of a vehicle using a low power fully active suspension system. The suspension system includes a hydraulic actuator operably connected at each corner of the vehicle between sprung and unsprung portions thereof, sensors for detecting movement of the sprung and unsprung portions of the motor vehicle and for deriving a force signal for each actuator in response thereto, and a valving arrangement for causing the hydraulic actuator to generate a desired output force in response to the force signal. The valving arrangement has a first valving that is operable for generating the output force by selectively varying the damping characteristics of the hydraulic actuator when the force signal is within a predetermined range. The valving arrangement also includes second valving for selectively controlling the supply and discharge of hydraulic fluid between the hydraulic actuator and a fluid pressure source for generating the output force when the force signal is outside of the predetermined range. Thus, the lower power fully active suspension system is adapted to produce the desired output force through selective actuation of the first and second valvings for limiting the duty cycle and power requirements of the fluid pressure source.

摘要： A damping device operable to change a suspension characteristic of a vehicle in response to changes in a relative relationship between the piston and the cylinder of the damping device. The damping device comprising a pressure cylinder forming a working chamber operable to store damping fluid. A piston is disposed within the pressure cylinder defining an upper and lower portion of the working chamber. The damping device further comprises a transducer for emitting and receiving sound waves within the lower portion of the working chamber. The sound waves emitted by said transducer are reflected by the end surface of the cylinder or a base valve mounted at the end of the cylinder and are received by said transducer. A timing circuit determines the difference in time between the emitted and reflected sound waves and generates an output in response thereto. A central processor calculates the desired relative relationship, such as the relative distance between the piston and the base valve, from the output of the timing circuit.

摘要： In a remote controlled fluid piston-piston rod type damper, a ported damping piston divides a cylinder into upper and lower chambers, a "spoiler" sleeve reciprocably encircles an electrical coil, a pair of shoulders extend radially from the piston rod, and a pair of precompressed coil springs position the piston between the shoulders for reciprocable axial movement relative to the piston rod. An electrically controlled valve operates to regulate flow between the chambers in response to relative reciprocable motion between the piston rod and the piston, the electrical coil being energized by an alternating voltage input whereby to generate a magnetic field about the sleeve. Movement of the spoiler sleeve through the magnetic field changes the current in the electrical due to self-inductance, and a remote control module generates a control signal, in response to the change in coil current, to actuate the electrically controlled valve whereby to regulate flow between the chambers.

摘要： A direct acting hydraulic damper comprising an internal, non-contact sensing means for the direct measurement of relative velocity between the piston and the cylinder of the damper. The damper comprising a cylinder forming a working chamber operable to store damping fluid. A piston is disposed within the cylinder defining an upper and lower portion of the working chamber. The damper further comprises a first transducer for emitting ultrasonic waves within the lower portion of the working chamber. The ultrasonic waves emitted by said first transducer are reflected by a base valve or end surface of the cylinder facing the transducers and are received by a second transducer. A frequency detection circuit determines the difference in frequency between the emitted and reflected ultrasonic waves and generates an output in response thereto. A computer then calculates the relative velocity of the piston with respect to the base valve or end surface, based on the Doppler principle. The velocity signal is then used for automatic control of suspension parameters according to predefined algorithm.
