    • A method and apparatus is provided for driving a throttle blade about an axis of rotation between maximum and minimum airflow positions. The throttle assembly includes a throttle body with an airflow passage. The throttle blade is mounted for rotation with respect to the body between the maximum and minimum airflow positions. The throttle blade has a central bore for receiving at least a portion of a drive mechanism. The drive mechanism includes a motor operably connected to a gear drive to move the throttle blade between the maximum and minimum airflow positions. In one example, the drive mechanism is preassembled in a tube that is inserted into the blade bore during assembly. A position sensor is also mounted within the bore to monitor the position of the blade relative to the body.
    • 提供了一种用于在最大和最小气流位置之间围绕旋转轴线驱动节流叶片的方法和装置。 节气门组件包括具有气流通道的节气门体。 安装节流叶片相对于主体在最大和最小气流位置之间旋转。 节流叶片具有用于接收驱动机构的至少一部分的中心孔。 驱动机构包括可操作地连接到齿轮传动装置的马达,以在最大和最小气流位置之间移动节流叶片。 在一个示例中,驱动机构预先组装在组装期间插入叶片孔中的管中。 位置传感器也安装在孔内以监测刀片相对于身体的位置。
