Conventionally, in a throttle valve control device for an internal combustion engine known from Japanese Patent Application Laid-Open No. 60-95144, a full-open stopper has been provided on a lever fixed to the throttle valve shaft. In the linkage consisting of three levers, no consideration was given to reliability and durability against impact when fully opened.

Regarding the impact when fully opened, the above-mentioned conventional technology has
Not much consideration was given to this, and there were problems with the durability and reliability of the throttle valve drive device. A throttle valve drive consisting of lever A fixed to the throttle valve shaft, lever B having an axis parallel to the throttle axis and rotatably attached to the throttle body and connected to the accelerator, and lever C connecting lever A and lever B. In the device, lever A was provided with a full-open stopper for controlling the full-opening angle of the throttle valve. Therefore, the force from the accelerator is transmitted to lever A via lever B, lever C, and the joint between each lever, and is throttled by the physical interference between the full-open stopper provided on lever A and other members. The valve was under control. Therefore, an excessive load is locally and momentarily applied to the smoothly rotating joint portion, posing a problem in durability.

In the linkage configured as described above, the force from the accelerator is transmitted to lever B via a cable etc.
The signal is transmitted to the joint, lever C, joint, lever A, and then to the throttle valve, and the throttle valve begins to open.
Physical interference occurs between the fully open stopper provided on lever B and the throttle body, and the throttle valve stops. In this series of operations, the pulling force of the accelerator and the stopping force of the fully open stopper are applied to one lever B, so that no excessive force is applied to the joint. This allows the joint to maintain an appropriate clearance and smooth sliding surface, greatly improving reliability and durability.

An embodiment of the present invention will be described below with reference to FIG. The intake passage 1 of an internal combustion engine is the throttle body 2
The throttle valve 3 is formed within the throttle valve shaft 4 and is fixed to the throttle valve shaft 4 . A lever A5 is fixed to the end of the throttle valve shaft, a shaft 6 is parallel to the throttle valve shaft and is fixed to the throttle body, and a lever B7 is rotatably attached to the shaft 6 and connected to the accelerator. Lever A5 and lever B7 are connected by lever C8. Spirings (not shown) are attached to the shafts 4 and 6, respectively, and provide return torque to the throttle valve. Further, the throttle valve is set to the idle opening degree by an adjuster screw 9, and an accelerator wire 11 is connected to the pin 10, and the other end of the throttle wire is interlocked with the accelerator. A full-open stopper 12 for the throttle valve 3 is provided on the lever B7. Further, the stop screw 13 allows adjustment of the fully open position of the throttle valve. Joint parts 14 and 15 having appropriate clearances and smooth sliding surfaces are interposed between the levers A, B, and C, respectively, and constitute a throttle valve driving device.

Force is transmitted to the joint part 14, lever C, joint part 15, and lever A to drive the throttle valve. Because the same lever receives the force from the accelerator and the impact force from the stopper, no undue force is applied to other parts, allowing for permanently smooth operation.

According to the present invention, the durability and reliability of the three-lever throttle valve drive device can be improved. Moreover, since it is a mechanical structure design, the cost is relatively low despite its large merits, making it suitable for mass production.
