Abstract
The utility model relates to the technical field of an engine, in particular to a valve plate type changeable air inlet channel system for an intake manifold. The valve plate type changeable air inlet channel system consists of a plurality of intake manifold valve plate units, wherein each intake manifold valve plate unit comprises an intake manifold valve plate and a valve plate support shaft, each intake manifold valve plate is mounted on the corresponding valve plate support shaft through a bearing, and a shaft bushing and an O-ring are arranged between each valve plate support shaft and the corresponding bearing. An axial gap is arranged in each shaft bushing. The end parts of the valve plate support shafts of two adjacent intake manifold valve plate units are butted. According to the valve plate type changeable air inlet channel system, one shaft bushing and one O-ring are additionally arranged between each valve plate support shaft and the corresponding bearing, the eccentricity of valve plates, caused by manufacturing and assembly deviation of parts, can be absorbed, and the production control is facilitated; the increased gap between each valve plate support shaft and the corresponding bearing, due to abrasion of parts, can be absorbed; the intake manifold valve plate units are connected in series into a whole, so as to reduce the vibration of the intake manifold valve plates and the abrasion of key parts of the system due to vibration.
Description
Technical field
The utility model relates to technical field of engines, is specifically related to a kind of variable air inlet road system.
Background technique
Variable air inlet road system is according to the motor different rotating speeds, uses the intake manifold of different length and volume to inflate in cylinder, in order to can form inertia inflation effect and resonant pulses wave effect, thereby improves charging efficiency and engine power performance.Specifically, low speed torque and idling that thin and long intake duct is conducive to motor are stable, short and thick intake duct is conducive to the engine power lifting when the high rotating speed of large load (the intake manifold air flue is longer, the vibration frequency of air in intake manifold is just lower, otherwise the intake manifold air flue is shorter, and the vibration frequency of air is higher).Be provided with the intake manifold valve block for conversion air flue length in intake manifold, use the progress air flue when engine idle or the slow-speed of revolution, converting to during high rotating speed loses heart reduces intake resistance raising intake efficiency.
Existing variable air inlet road system comprises several intake manifold valve blocks unit, and described each intake manifold valve block unit is an absolute construction, comprises intake manifold valve block and valve block back shaft, and described intake manifold valve block is arranged on the valve block back shaft by bearing.The shortcoming that has is: 1. the manufacturing of system parts and assembling deviation can cause the bias between the intake manifold valve block; 2. in working procedure, due to the parts wear that is difficult to avoid, can cause the increase of valve block back shaft and bearing gap; 3, the vibration frequency of single intake manifold valve block is large, easily causes the wearing and tearing of system core component.
The model utility content
The purpose of this utility model is, a kind of valve plate-type variable air inlet road system for intake manifold is provided, and solves above technical problem.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of valve plate-type variable air inlet road system for intake manifold, formed by several intake manifold valve blocks unit, described intake manifold valve block unit comprises intake manifold valve block and valve block back shaft, described intake manifold valve block is arranged on the valve block back shaft by bearing, it is characterized in that: be provided with axle bush and O type circle between described valve block back shaft and bearing, described muff is connected on the valve block back shaft, and described O type snare is connected on axle bush.
Described axle bush is provided with an axial breach.
The end of the valve block back shaft of described adjacent two intake manifold valve block unit is docking together.
In the end of described two valve block back shafts that connect, the end of one of them valve block back shaft is provided with draw-in groove, and the end of another valve block back shaft is provided with the projection corresponding with draw-in groove, and described draw-in groove is installed on projection.
Beneficial effect: owing to adopting technique scheme, the utlity model has following advantage: increased axle bush and O type circle between valve block back shaft and bearing, the flexibility of O type circle can absorb the bias between the manufacturing of component and valve block that assembling deviation causes, is convenient to manufacture control; If the comprehensive function of axle bush jaggy and O type circle can absorb the valve block back shaft that causes because of parts wear and the increase of bearing gap; By the docking of valve block back shaft, be connected into and be structure as a whole between each intake manifold valve block unit, can reduce the vibration of intake manifold valve block and the wearing and tearing of the system core component that caused by vibration.In a word, compared with prior art, the robustness of variable air inlet described in the utility model road system is stronger.
Description of drawings
Fig. 1 is the structural representation of valve plate-type variable air inlet described in the utility model road system;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is the structural representation of axle bush described in the utility model and O type circle.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with the further elaboration the utility model of concrete diagram.
With reference to Fig. 1-Fig. 3, valve plate-type variable air inlet road system for intake manifold described in the utility model, formed by several intake manifold valve blocks unit, described intake manifold valve block unit comprises intake manifold valve block 1 and valve block back shaft 2, and described intake manifold valve block 1 is arranged on valve block back shaft 2 by bearing 3.Be provided with axle bush 4 and O type circle 5 between described valve block back shaft 2 and bearing 3, O type circle can adopt whippy rubber material to make.Described axle bush 4 is socketed on valve block back shaft 2, and described O type circle 5 is socketed on axle bush 4.But the bias between the flexibility absorption system component manufacturing of O type circle 5 and the intake manifold valve block valve block that assembling deviation causes.
Described axle bush 4 is provided with an axial breach 41, can by the elastic force of O type circle 5, adjust the gap between valve block back shaft 2 and axle bush 4.
The end of the valve block back shaft of described adjacent two intake manifold valve block unit is docking together, specifically, in the end of described two valve block back shafts that connect, the end of one of them valve block back shaft is provided with draw-in groove 21, the end of another valve block back shaft is provided with the projection corresponding with draw-in groove 22, and described draw-in groove 21 is installed on projection 22.By the docking of valve block back shaft, be connected into and be structure as a whole between each intake manifold valve block unit, can reduce the vibration of intake manifold valve block and the wearing and tearing of the system core component that caused by vibration.
