Embodiment 1
[0029] An automobile electronic throttle valve, comprising a base 1, a main air passage 4 installed on the main body of the base, and a valve 8 installed in the middle of the inner cavity of the main air passage, the valve includes a door shaft 81 and a door sheet 82, the automobile The electronic throttle is equipped with an electric control mechanism to control the opening and closing of the valve and a damping device for keeping the valve door in a horizontal state when the vehicle is in an idle state; the electric control mechanism is installed on one side of the base, including a micromotor 5 And transmission gear, described micro-motor 5 is connected with the door rotating shaft 81 transmission gear of valve 8 through transmission gear, and described micro-motor is one-way motor; Described transmission gear comprises driving wheel 6, intermediate wheel 3 and driven wheel 2, and described The driving wheel is connected with the rotating shaft of the micro-motor, the driven...
Embodiment 2
[0033] An automobile electronic throttle, its structure is basically the same as that of Embodiment 1, the difference is: the transmission gear has no intermediate wheel, and only includes a driving wheel 6 and a driven wheel 2, and the driving wheel is connected with the rotating shaft of the micro-motor, The driven wheel is connected to the door shaft of the valve, and the driven wheel 2 is meshed with the driving wheel 6. The stop device is installed on the base of the driven wheel 2 side: including ratchet 71 and ratchet shaft 72, one end of the ratchet Rotate and connect around the ratchet shaft, and the other end elastically meshes with the gear teeth on one side of the driven wheel.
[0034] Above-mentioned embodiment 1~embodiment 2 is one of preferred embodiments of the present invention, as the transformation of above-mentioned embodiment 1-embodiment 2:
[0035] The door piece of the valve can also be combined with the door shaft into a whole by riveting, welding, tw...
