Description

Technical Field

[0001] The utility model relates to the technical field of automotive engine electronic throttle, and particularly relates to a novel electronic throttle valve body. Background Art

[0002] An electronic throttle (Electrical Throttle valve Control) is an electric continuously position-adjustable and controllable valve assembly used to control the entry of fresh air into the engine. According to the requirements of the control unit, the electronic throttle drives a motor to precisely control the opening of the valve plate, thereby controlling the air flow into the engine, improving fuel economy, and reducing emission pollution.

[0003] When rapid deceleration is required, such as when the driver suddenly releases the accelerator pedal, the polarity of the driving motor will be reversed and it will rotate quickly to fully close the throttle valve. During the rapid closing process, the seating rate is high and the seating impact is large, which easily causes situations such as the plastic gear being broken, the rotation stroke being too large, and the valve plate getting stuck, resulting in faults such as jamming and lack of acceleration power.
