  • Electronic throttle control mechanism with reduced friction and wear
    Patent number: 6575427
    Abstract: An electronic throttle control system having a housing and cover member with a throttle valve, gear mechanism, motor, and failsafe mechanism. A spring member positioned between the housing and sector gear member which is attached to the throttle valve shaft, biases the throttle valve plate member toward the closed position. A spring-biased plunger member biases the throttle plate member from its closed position to a default or “limp-home” position. A stop shoulder on the sector gear is transverse to the longitudinal axis of the plunger mechanism midway through the default range of travel of the sector gear and plunger member. This reduces stresses on the components and minimizes friction and wear on the gear train mechanism.

  • Rotating shaft assembly
    Patent number: 6299545
    Abstract: A shaft assembly and method of manufacture are provided. A molded member is attached to the shaft. An axially extending groove is provided in the shaft, the groove having a bottom and a pair of radially projecting sides. A member is molded onto the shaft. A portion of the member flows into the groove and engages the groove sides, thereby fixing the member to the shaft.

  • Electronic throttle return mechanism with a two-spring and one lever default mechanism
    Patent number: 6286481
    Abstract: An electronic throttle control system having a housing 22 with a motor 40, throttle valve 60, gear mechanism 100, and failsafe mechanism. A main spring member 130 positioned between the housing 22 and a gear mechanism 104, which in turn is attached to the throttle valve shaft 62, biases the throttle plate 60 towards the closed position. A spring-biased default mechanism 132, 134 biases the throttle plate 60 from its closed position to a default or “limp-home” position.

  • Electronic throttle return mechanism with default and gear backlash control
    Patent number: 6267352
    Abstract: An electronic throttle control system having a housing 22 with a motor 40, throttle valve 60, gear mechanism 100, and failsafe mechanism 130. A main spring member 150 positioned between the housing 22 and a gear mechanism 104, which in turn is attached to the throttle valve shaft 62, biases the throttle plate 60 towards the closed position. A spring-biased gear backlash sector gear mechanism 130 biases the throttle plate 60 from its closed position to a default or “limp-home” position.

  • Electronic throttle return mechanism with a two-spring and two-lever default mechanism
    Patent number: 6253732
    Abstract: An electronic throttle control system having a housing 22 with a motor 40, throttle valve 60, gear mechanism 100, and failsafe mechanism. The failsafe mechanism comprises two springs 130, 150 and two levers 140, 160 which are used in combination with a gear member and an adjustable stop screw 170 on the housing.

  • Electronic throttle control with adjustable default mechanism
    Patent number: 6095488
    Abstract: An electronic throttle control system having a housing with a motor, throttle valve, gear mechanism, and fail-safe mechanism. A spring member attached to a gear member and default lever, and which is biased when the throttle valve is in its fully open and closed positions, operates to open the throttle valve in the event of an electric failure, thus allowing the vehicle to limp home. An adjustable pin member is used to adjust the position of the default lever and thus the throttle valve in a fail-safe situation.
