  • Throttle body shaft axial play control
    Patent number: 6244565
    Abstract: An electronic throttle control system with a housing having a motor, throttle valve and gear mechanism. The throttle valve is attached to a throttle body shaft which is mounted in bearings in the housing. An axial spring clip mechanism mounted on the throttle body shaft preloads the bearings and eliminates undesired axial and radial movement of the shaft which could adversely affect the movement of the throttle valve and the sensing of its position.

  • Electronic throttle control system with two-spring failsafe mechanism
    Patent number: 6173939
    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 spring member 150 attached between the housing 22 and a gear member 104 attached to the throttle valve shaft 62 biases the throttle plate 60 towards the closed position. A spring-biased plunger member 134 biases the throttle plate 60 from its closed position to a default or “limp-home” position.

  • Default mechanism for electronic throttle control system
    Patent number: 6155533
    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.

  • Electronic throttle control system
    Patent number: 6070852
    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. The spring member, default lever and associated gear member are interfit together as a group and inserted in the housing as a subassembly, thus improving assembly time and expense.
