Description
Technical field:
The utility model belongs to automobile parts equipment technical field, relates more specifically to a kind of automobile windage device.
Background technique:
The major name of automobile tail fin is " automotive spoilers ", also referred to as spoiler, is belonged in automobile air power external member
A part.The main function of spoiler is the lift in order to reduce vehicle tail, if the lift of the tailstock is than the lift of headstock
Greatly, it is easy for that vehicle oversteering, the reduction of rear-wheel road holding and high stability is caused to be deteriorated.
When automobile high-speed passes through, air can pass through vehicle body outer profile, finally move obliquely.According to the forst law of motion,
Power is the reason of changing object moving state, and further according to Newton's third law, active force and reaction force etc. are big reversed, and air is certainly
One upward power of automobile so can be also given, is like in the lifting tailstock upwards.
By upward power, the adhesive force on rear-wheel will decline the tailstock.So in negotiation of bends, rear-wheel is capable of providing
Lateral force will decline, this will make vehicle be easier to break away, that is, so-called " ovdersteering ".This is for height
It is the breakneck thing of part for vehicle in speed traveling.Then, spoiler there have been.
But when the operation of car body low speed, spoiler does not have the effect for increasing adhesive force not only, and windage increases vapour
The oil consumption of vehicle.Bugatti Veyron and the empennage of Ferrari be usually received in the inside, when speed height to a certain extent when just pop-up
Come.Angle by changing empennage can effectively change lower pressure and windage.Prestige dragon is after being more than speed per hour 200KM/H, just
Empennage angle can automatically be changed, this is just as the reason wing resistance effect when aircraft landing.This " air lock " exists
Maximum can produce the deceleration of 0.6g when high speed, which activated by brake pedal.
But car body be higher than 160KM/H, light by car body itself braking be it is inadequate, braking distance is to lead to accident
The main reason for one of, car body how to guarantee when high-speed cruising car body stablize while, and can be effectively reduced braking away from
From being emphasis of the present utility model.
