Description
Technical field
The utility model relates to a kind of gas handling system of engineering heavy-duty car, particularly relates to a kind of air cleaner assy.
Background technique
At present, explosive motor is the most important assembly of car load, and it provides power for car load, and its performance directly affects vehicle performance.The effect of gas handling system provides low flow resistance, clean, dry, sufficient air to motor.Air-strainer is component crucial in gas handling system, and air-strainer should be reduced to the acceptable level of motor dust concentration, removes large particle, reduces engine noise, reduces gas-flow resistance as much as possible, meet the requirement of motor.The air-strainer that matching performance is good can extend engine life, improves engine performance, reduces engine scuffing.The filtration system be equipped with can make motor longer for service time, burns more abundant.In addition, energy consumption and toxic emission can also be reduced.
Along with the development of internal-combustion engine technology, air-strainer is also constantly meeting the different requirement of internal-combustion engine.Particularly high-powered engine widely uses, the requirement of air-strainer is also being improved constantly, while requiring the air that air-strainer provides clean, dry, sufficient, also require that the volume of air-strainer reduces as much as possible, the car load assembly space that minimizing takies.
Model utility content
For the problem in background technique, the utility model proposes a kind of air cleaner assy, comprise air outlet, front cover, housing, main filter core, safety filter element, bonnet, dust discharge valve and suction port, front cover and bonnet are positioned at the two ends of housing, air outlet is by the inner space of front cover and housing, dust discharge valve is by the inner space of bonnet and housing, the inner space of suction port and housing, main filter core is placed in the inner chamber of housing, safety filter element is placed in the inner chamber of main filter core, shell inner surface and main filter core outer surface form a cavity, air outlet, housing, main filter core is identical with the shaft axis of safety filter element, its improvement is: this air cleaner assy also comprises airscoop shroud, this airscoop shroud is placed in cavity, one end of airscoop shroud is positioned at one end that housing is connected with front cover, the position of suction port and the position of airscoop shroud outer surface match.
Further, the utility model has also done following improvement: airscoop shroud comprises stack shell and base, and stack shell and base are the cylinder overall structure of concentric, stack shell and base, inner diameter identical with outer diameter; The periphery of stack shell is provided with helical duct, and the periphery of base is provided with blade; The position of suction port and the position of helical duct match.
The helical duct being arranged on stack shell and the blade structure being arranged on base outer perimeter form a spirally inlet air passage, make to form vortex gas-flow by the air flow energy of spirally inlet air passage, the dust in vortex gas-flow can gather the edge of air-flow under the influence of centrifugal force rapidly; When vortex gas-flow is by blade, eddy flow will be strengthened further, and the dust in vortex gas-flow can be rotated along the internal surface of air filter housing.
Advantageous Effects of the present utility model is: structure is simple, can make formation spirally inlet air passage, air-flow can be made to form eddy flow, the dust rapid aggregation in air-flow can be made to the edge of air-flow, dust is rotated along the internal surface of air filter housing.
