Abstract
To enhance assembling property of a throttle valve control device comprising a mechanical drive means and an electric drive means, and to enhance maintenance property at the time of checking and exchange operations of an accelerator wire, the electric drive means and the mechanical drive means are provided at an one side wall 1a of a throttle body 1 toward the one side wall 1a side from the one side direction A, the electric drive means comprises throttle valve lever 5 including a throttle valve lever open spring 8, a motor gear 9, and a drive gear 6 including an intermediate gear 10, and the mechanical drive means comprises a limb opening control lever 15, and an accelerator drum 14 including a drum close spring 16.
Claims4
A throttle valve control device comprising:
- a throttle valve shaft crossing an intake passage, being rotatably supported by a throttle body, and being mounted with a throttle valve for opening/closing the intake passage;
- a throttle valve lever being fixedly provided at the throttle valve shaft, being rotated synchronously with the throttle valve shaft, and being energized in the opening direction of the throttle valve by a throttle valve lever open spring;
- an accelerator drum being provided at an one end of a drum shaft, being mechanically rotated and operated in the opening/closing directions of the throttle valve by an accelerator wire, and being energized in the closing direction of the throttle valve by a drum close spring;
- a limb opening control lever being provided at an another end of the drum shaft, facing the throttle valve lever, and being for controlling to make an opening position of the throttle valve lever by the throttle valve lever open spring to a limb opening position of the throttle valve, in a full closing operation position of the accelerator drum;
- and
- a drive gear being rotated and controlled by a motor gear rotated synchronously with a motor, being rotatably supported by the throttle valve shaft, being for controlling a throttle valve open directional position of the throttle valve lever and a throttle valve close directional position of the throttle valve lever, and being for controlling opening/closing of the throttle valve corresponding to rotation of the motor, in which the drive gear is driven and controlled through the motor so as to make the opening position of the throttle valve correspond to the opening position of the accelerator drum;
- wherein the throttle valve lever including the throttle valve lever open spring, the drive gear including the motor gear, and the accelerator drum including the limb opening control lever and the drum close spring are provided at a one side wall of the throttle body.
