Description

[Technical field]

[0001] The invention relates to the technical field of throttle valves, in particular to the technical field of a dual-flow channel throttle valve assembly. [Background technology]

[0002] The throttle is an important component in the electronic fuel injection system of the engine. It is connected to the air filter at the top and the engine block at the bottom. It is called the throat of the automobile engine. The throttle generally includes a housing, an air flow channel located in the housing, a throttle shaft that rotates and is fixed in the air flow channel, a throttle plate installed on the throttle shaft, and a driving device that drives the throttle shaft to rotate. The throttle drives the throttle plate to rotate through the driving device, closing or opening the air flow channel, thereby controlling various working conditions of the engine by controlling the air flow rate sucked into the engine.

[0003] At present, the connection method between the throttle plate and the throttle shaft is generally to first set a mounting groove on the throttle shaft, then pass the throttle plate through the mounting groove, and use a number of bolts set on the throttle shaft to lock and fix the throttle shaft and the throttle plate. However, the size of the mounting groove on the throttle shaft is difficult to fully adapt to the throttle plate, and there is a small gap, which makes it difficult for the throttle plate to completely close the air flow channel, causing air leakage. In addition, the existing throttle valve usually has only one air flow channel. When the car enters a place with thin air such as a high altitude or the air inlet of the throttle valve is blocked, the throttle valve intake is low, and the car is prone to insufficient power.
