Description

Stable automobile throttle valve Technical Field The utility model relates to the technical field of automobile electric control, in particular to a stable automobile throttle valve. Background The automobile throttle valve is a key component in an automobile engine system and is positioned in an air inlet pipeline, and the main function of the automobile throttle valve is to control the air quantity entering an engine, and the proportion and quantity of the mixed gas can be accurately controlled by adjusting the opening and closing degree of the throttle valve, so that the performance indexes such as power, rotating speed and oil consumption of the engine are affected. The throttle valve is typically operated by the driver via an accelerator pedal to meet different driving demands. Meanwhile, modern automotive throttle valves are often equipped with electronic control systems to achieve more precise control. The publication number is CN206668413U discloses an electronic throttle valve of an automobile, which comprises a throttle valve body, an end cover, a direct current motor and a gear transmission mechanism, wherein the end cover is connected with the throttle valve body in a matched manner; the throttle valve body comprises a motor cavity, a gear cavity and a gas channel, wherein the direct current motor is fixed in the motor cavity of the throttle valve body through a motor pressing plate and a bolt, and the gear transmission mechanism is connected in the gear cavity of the throttle valve body in a matched mode.
