Linkage type multi-cylinder electronic throttle valve assembly

Abstract

The invention discloses a linkage type multi-cylinder electronic throttle valve assembly. The linkage type multi-cylinder electronic throttle valve assembly comprises a throttle valve housing, whereinthe throttle valve housing is provided with 2N throat openings which penetrate in the same direction; valve plates are arranged in the throat openings; N rotating shafts are arranged on the throttlevalve housing; each rotating shaft is connected with two corresponding valve plates, and can synchronously rotate under the driving of the same rotating shaft driving mechanism; the rotating shaft driving mechanism comprises a motor, a middle gear set and rotating shaft driving gears which are fixedly arranged at the same ends of the rotating shafts in a sleeving mode; the adjacent rotating shaftdriving gears are meshed with each other; and the motor can drive one of the rotating shaft driving gears through the middle gear set. By adopting the technical scheme, the shaft distance between therotating shafts is greatly reduced, meanwhile, the overall size of the throttle valve is reduced, the occupation of the installation space is reduced, the assembly can be suitable for more applicationscenes, moreover, the structure is more simplified, the cost is reduced, and the assembly efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of throttle valves, in particular to a linked multi-cylinder electronic throttle assembly. Background technique [0002] The throttle is a controllable valve that controls the air entering the engine. After the gas enters the intake pipe, it will be mixed with gasoline to become a combustible mixture, which is burned to form work. It is connected with the air filter on the top and the engine block on the bottom, which is called the throat of the automobile engine. Compared with a purely mechanical throttle valve, the electronic throttle valve can control the throttle opening more accurately, achieve a more reasonable air-fuel ratio, make the mixed gas burn more fully, reduce emissions, and improve the power, economy and comfort of the engine Sex. [0003] Existing multi-cylinder electronic throttles (such as four-cylinder electronic throttles) usually use a motor to drive each shaft to rotate synchronously. The m...

Problems solved by technology

[0003] Existing multi-cylinder electronic throttle valves (such as four-cylinder electronic throttle valves) usually use a motor to drive each rotating shaft to rotate synchronously. The gears rotate synchronously, resulting in a large wheelbase between the rotating shafts, which makes the overall size of the throttle valve large, not only takes up a lot of installation space, it is difficult to meet some special needs, but also the structure is relatively complicated and the cost is high
