What is car tail?

refers to a tail car automobile trunk lid, the protrusion rear end of the apparatus in the form of duck, aerodynamics part of the car belongs. The main role is to reduce lift the rear of the vehicle.

1. Introduction automobile tail noun

is an automobile car tail trunk lid, projections in the form of duck tail rear end loaded, aerodynamics part of the car belongs. The main role is to reduce lift the rear of the vehicle. Some people abroad based on its shape vividly calls it “sled board.” There are also some people call it “duck tail” or “wing”, should be more scientific name for “spoiler” “spoiler” or “spoiler.” Single and double fin generally divided two kinds of aluminum alloy and carbon fiber tail of two materials, and the sub-hydraulic automatic adjustment and manual adjustment, wherein the hydraulic multi-hydraulic automatic tuning posts, according to the vehicle speed automatically adjust the angle.

2. Automobile tail works

car at high speeds, according to the principles of aerodynamics, will encounter during driving the air resistance, the center of gravity around the car while generating longitudinal, lateral and vertical rising aerodynamic forces in three directions, wherein the longitudinal air resistance.

In order to effectively reduce and overcome the air resistance of the car at high speed, have been designed using a tail car, its role is to generate a fourth car air force, i.e., a greater on the ground adhesion, can partially offset the lift, effective control of floating cars, so that a corresponding reduction in the drag coefficient of the car can be in close contact with the road surface, thereby improving the running stability.

3 function and classification

Function automobile tail, that is, when the car at high speed, the air resistance is formed a downward pressure, as far as possible offset lift, effective control of the air flow under pressure, so that drag coefficient corresponding decrease, increase vehicle stability at high speed; tail can be reduced due to the air resistance of the car, thus the installation of a high-speed car to save fuel tailAlso has some help; but also make the car more beautiful shape, play a decorative role.

Depending on the material, a common automobile tail fin into fiberglass, aluminum fin, carbon fiber tail three.

Fiberglass tail: tail such diverse forms, there Benn shaped, airfoil-shaped, has straight plate. Pretty good shape, but glass fiber reinforced plastic material more brittle, toughness and rigidity are poor, the price is cheaper.

Aluminum fin: the tail of such diversion and thermal effect is good, and affordable, but lighter than other materials tail slightly heavier.

Carbon fiber tail: carbon fiber tail rigidity and durability are very good. Not only lightweight but also the most beautiful kind of tail. F1 racing is now widely adopted but the price is relatively expensive.
