Description
Technical field
The utility model is related to a kind of automobile and its dust-arrest device.
Background technology
At present, in vehicle traveling process, due to automobile own form design feature, automobile is caused to produce in motion
The adhesive force reduction on upward lift, automobile and ground, when running car speed per hour is higher, this phenomenon is then more prominent.For
Alleviate harmful effect of the lift for Riding Stability of Automobile as far as possible, designer often sets about from car shaped, right
Car shaped carries out certain optimisation, so as to reduce the lift of generation.In addition in high-performing car, sport car or racing car, in order to
To the adhesive force on ground when raising automobile is excessively curved, also front wing or empennage, front wing, empennage can be installed on the head of automobile or afterbody
Fin its cross sectional shape aircraft airfoil section shape it is similar, but its mounting means and aircraft wing contrast, air stream
During through front wing, the upper and lower surface of rear wing fin, the pressure differential on upper and lower surface will produce the pressure acted on downwards, help automobile
Head or afterbody close proximity to ground, improve adhesive ability of the vehicle to ground.But during actual travel, particularly cross at a high speed
In the case of bend, the trend that automobile can be rolled on the outside of oriented bend due to centrifugal action, positioned at the tire of curve inner side
Its normal pressure being subject to is reduced, and the normal pressure increase that the tire on the outside of bend is subject to, and automobile larger inclination occurs and is easily caused
The situation that automobile is broken through the limit of adhesion of bend outboard wheels and slid.However, because front wing, rear wing are for vehicle right and left

The base of dynamic auxiliary cylinder, aileron cylinder cylinder body is rotated with location-plate and is connected, and described fluid pressure line includes hydraulic pump, for leading to simultaneously
The aileron pipeline of disconnected two aileron cylinders and the rotation auxiliary piping that auxiliary cylinders are each rotated for independent break-make.The adjustable angle
The lower pressure and air drag of the automobile tail left and right sides can be adjusted for formula dual turbulent device, so as to improve automobile tack
, loading of tire can be reduced.
But during empennage angle adjustment, influenceed by the flow direction change of air-flow during empennage pitching, air-flow can be in tail
The rear of the wing forms turbulent flow, and the turbulent flow can roll the airborne dust below the tailstock, cause the adhesion condition of tailstock airborne dust to aggravate, seriously
When the outlet of the offgas duct of the tailstock can be caused to hinder, cause vehicle outlet not smooth, engine disorderly closedown.
The content of the invention

The top barrel of section is less than the inclination barrel on front side edge edge for rear lateral edge.
The width of each flabellum gradually increases from top to bottom.
The deck of U-shaped is fixed with the top surface of bellows, deck has two, the spaced distribution of two decks.
The technical scheme of automobile is as follows in the utility model：
Automobile, including car body, the afterbody of car body are provided with the flow spoiler positioned at top, and the afterbody of car body is provided with the bottom of positioned at
The dust-arrest device in portion, dust-arrest device includes the flabellum of the bellows and the louvered being arranged in bellows installed in tailstock bottom, wind
Case has the air inlet and the air outlet positioned at rear side positioned at front side；What each flabellum was parallel to each other is obliquely installed, the rear side of flabellum
Edge is less than front side edge edge.
Air outlet is angular cut, and the bottom sides edge of air outlet is located at the front on top sides edge.
Bellows are made up of the direct tube section being connected from front to back and oblique cylinder section, and oblique cylinder section is the U-shaped cylinder of bottom opening, oblique cylinder
