Abstract

The invention provides an intake manifold variable system. The intake manifold variable system comprises a plastic bearing, an integral valve plate, a metal bearing, a metal shaft sealing ring, a plastic swing arm, a vacuum actuator, and a self-tapping nail for fixing the vacuum actuator, wherein the integral valve plate comprises a metal shaft, and four valve plates formed on a metal shaft through injection molding. The intake manifold variable system can be finished only by few parts, so that a variable mechanism is simplified, and the assembly efficiency is high and the rejection rate is low after mass production; and as the variable mechanism simplifies the structure, the performances are stabilized, such problems as noise and blockage easily generated by the variable system in a variable intake manifold are solved, and the durability and the reliability of the intake manifold variable system are improved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a variable intake manifold system. Background technique [0002] The existing intake manifold valve plate variable mechanism generally drives the metal swing arm and the valve plate to move through a vacuum actuator, and prevents the swing arm from falling off through a self-locking nut. [0003] Ordinary valve-type intake manifold has a large number of variable mechanism components, especially the valve plate needs to be realized through assembly structure, with many assembly steps and many coordination relationships. Once a part is damaged, the whole will not work normally and needs to be repaired out of the box . [0004] How to improve the stability and reliability of the variable mechanism of the intake manifold is an urgent problem to be solved at present. Contents of the invention [0005] The invention proposes a variable intake manifold system, which directly drives the mov...
