Description
Technical field
The present invention relates to a kind of double-deck spoilers.
Background technique
Because car body is usually an irregular fairing, vehicle separates air, and air is flowed through from vehicle's surroundings, and is worked as
After flowing through roof, this partial air can start to flow downward, and the flowing velocity of air-flow can be determined according to the shape of the tailstock here,
For example the tailstock is in order to more beautiful, thus many tailstock moulding all steepers, so air velocity also can be faster, it also will shape
Upward lift is obtained at the effect as wing, and the effect of rear spoiler is exactly under the premise of not increasing car body weight
Reduce climbing power suffered in vehicle driving.Concrete reason is because are as follows: automobile side view is similar to wing, its side is cut
Figure is asymmetric up and down, is that bottom is relatively flat, top curved.So it in high-speed motion, the front of vehicle also can be air-flow point
It separates and, a part flows through above car body, and another part flows through from below, so that it is in the feelings as wing in this way
In shape, cause the air velocity of car body upper and lower surfaces different, i.e., top flow velocity be greater than lower section flow velocity, so as to cause to
On pressure be greater than downward pressure.The pressure difference of the two also will form a lift, make automobile stress feelings in high-speed motion
Condition is as a wing, and by a upward lift, and can obtain speed more lift according to bernoulli equation also can be bigger,
The road holding (i.e. pressure of the automobile to ground) of automobile can thus be reduced.In extreme circumstances, as in the great situation of speed
It is entirely possible to make lift to be greater than car body gravity, it is liftoff that just will appear car body, the case where causing the race of engine, waste combustion
Oil even will appear danger sometimes, especially in corner.If this occurs, it just will appear automobile and do centrifugal movement
Situation, cause the accident of vehicle rollover.In order to avoid the appearance of such case, it is thought why not can be one
" anti-wing " is mounted on automobile, to form a lower pressure F opposite with airfoil lift.What so-called anti-wing here referred to
That an inverted wing is filled on automobile, it is characterized in that top is relatively flat, and bottom bend, make it in the air-flow of high speed on
The air velocity of side is less than the air velocity of lower section, and then the air pressure of top is made to be greater than the air pressure of lower section, formed one it is downward
Pressure moves generated lift so as to offset car body itself, and here it is the aerodynamic principles of empennage (spoiler).
On the one hand, it makes car shape add innervation to spoiler；On the other hand, its prior effect is effectively to subtract
Lack the air drag that vehicle is generated when running at high speed, both saved fuel, while also improving the stability of vehicle driving.
The right two kinds of moulding of conventional blow deflector at present: one is only deflectors and the homochromy spraying of vehicle body, without any decoration
Property part.Another kind is that deflector fills down one piece high brilliant black decorative panel again after the homochromy spraying of vehicle body.
