    摘要: A bushing assembly (42) adapted for application in vehicle suspension systems (10) includes an outer, generally cylindrical bushing member (50), an inner generally cylindrical bushing member (52) arranged concentrically within the outer member (50). The two bushing members (50, 52) are interconnected by an elastomeric member (54) disposed there between and bonded thereto to permit limited rotational displacement between the external and internal bushing members (50, 52). An angular position sensor (62) is at least partially embedded within the elastomeric member (54) and operated to produce an output signal indicative of the relative angular position of the external and internal bushing members (50, 52). The sensor (62) includes a stator assembly (102) including a permanent magnet (106), a galvanomagnetic sensing element (108) and a flux guide (110, 112) defining at least one pole face (122, 124), and a rotor (104) including a flux guide (126, 128) defining a second pole face (130, 132). An air gap (Ra, Rb) between the two pole faces (122, 124 & 130, 132) varies dimensionally as a function of the relative angular position of the stator assembly (102) and rotor (104).

    摘要: A method and apparatus for dynamically leveling the attitude of a vehicle (102) using a low power fully active suspension system (100). The system (100) connects the front and rear suspensions (114 and 104) and body (103) of the vehicle (102) and includes a hydraulic damper (110) having a pressure cylinder (144) forming a working chamber (146) in which a piston and rod assembly (148) is movably disposed. The system (100) further comprises a flow control device (130) fluidly communicating with the working chamber (146) on one side of the piston (148) for adding and exhausting damping fluid therefrom to a central pressure source (132), and an accumulator (128) fluidly communicating with the working chamber (146) on the opposite side of the piston (148). The system (100) having flow restriction valving (156) for selectively controlling the flow of fluid with said working chamber (146). The flow restriction valving (156) located between the flow control device (130) and the accumulator (128). The lower power fully active suspension system (100) is adapted to produce a desired suspension force output through selective actuation of the flow control device (130) and the flow restriction valving (156) for limiting the duty cycle and power requirements of the central pressure source (132).

In such a configuration, the electronic controller is capable of communicating electrical control signals to the actuation system (90) to thereby adjust the fore-aft position of the pair of wheels as necessary to actively maintain the fore-aft stability of the vehicle.
