Embodiment 1

[0046] figure 1 It is a schematic structural diagram of a variable intake manifold system provided in Embodiment 1 of the present application.

[0047] Such as figure 1 As shown, a variable intake manifold system provided by the embodiment of the present application includes: a metal shaft 1, a plurality of valve plates 2 forming an integrated valve plate group, a plurality of split bearing seats 3, two Bearing 4, two independent bearing blocks 5 and swing arm 6. Wherein, the valve sheet 2 includes: a hard rubber substrate 21 and a soft rubber coating 22 .

[0048] Among them: a plurality of valve plates 2 form an integrated valve plate group through plastic overmolding, and the integrated valve plate group formed by multiple valve plates 2 is fixed on the metal shaft 1 through plastic overmolding, and is connected with the metal shaft. 1 becomes an integrated structure; the two-piece bearing seat 3 is arranged between the adjacent valve plates 2; the two bearings 4 are bot...

Embodiment 2

[0059] figure 2 It is a schematic diagram of the detailed structure of the split bearing seat provided in the second embodiment of the present application.

[0060] Such as figure 2 As shown, the structure of the split bearing seat includes: a first half bearing seat 31 , a second half bearing seat 32 and a square positioning structure 33 . Wherein: the first half bearing seat 31 and the second half bearing seat 32 are fixed by the square positioning structure 33 .

[0061] The part connected between the first half bearing seat 31 and the second half bearing seat 32 can be reliably fixed and plugged by the square positioning structure 33, so as to realize the stable positioning between the two half bearing seats, effectively ensuring the split type The shape and position accuracy of the bearing seat. At the same time, due to the simple structure of the split bearing seat, the difficulty in manufacturing and assembly is reduced.

Abstract

The invention provides an air intake manifold variable system, which comprises a metal shaft, an integral valve plate group, two bearings, a plurality of butt-joint bearing seats, two independent-type bearing seats and an oscillating arm, wherein the integral-type valve plate group is fixedly arranged on the metal shaft through a rubber coating injection molding way; one butt-joint bearing seat is respectively arranged between every two adjacent valve plates; the two bearings are respectively arranged on the metal shaft and contacted with two valve plates on two ends of the integral valve plate group; the two independent-type bearing seats are arranged on the metal shaft, and the two bearings are respectively arranged inside the two independent-type bearing seats; and the oscillating arm is installed on the metal shaft. Through the integral valve plate structure formed through the rubber coating injection molding way and the assembling and positioning way of all parts, the duration and the reliability of the air intake manifold variable system can be improved, and the dynamic property of an engine is also improved.

Description

technical field [0001] The present application relates to the field of engines, in particular to a variable intake manifold system and a variable intake manifold. Background technique [0002] The intake manifold is one of the core components of the automobile engine, and its core function is to provide sufficient and uniform mixture for each cylinder of the engine, so it is a key factor affecting the power of the engine. However, under different engine speeds and loads, the demand for intake air volume is different. Therefore, in order to meet the different requirements of the engine for intake air at different speeds and loads, it is generally required that the engine be equipped with a thick and short intake manifold at high speeds and large loads; intake manifold. [0003] At present, many engines are equipped with variable intake manifolds. The variable intake manifolds in the prior art mainly control the variable intake manifolds by adopting a set of intake manifold ...
