Description

[0001] The present invention relates to a speed-sensitive rear spoiler apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear spoiler device, and more particularly, to a speed-responsive rear spoiler device that responds to a traveling speed of an automobile.

Generally, the vehicle generates a downward force by using the air flowing around itself when driving according to the type of vehicle, and this force pushes down the vehicle body, so that a spoiler for improving the stability of the vehicle is installed do.

In this way, the downward force acting perpendicular to the vehicle body improves the braking performance, steering performance, etc., and the magnitude of such force also helps alleviate the instability of the jerking due to the crosswind. Therefore, devices for reducing the aerodynamic drag force and increasing the downward force to improve the running performance and fuel efficiency of the vehicle have been produced and applied.

However, since the rear spoiler of the initial automobile is fixedly fixed with a fixed inclination angle of the spoiler, it generates a downward force which increases constantly according to the running speed. As a result, there has been a problem in that the stability of driving is lowered at a high speed. Generally, as the running speed of an automobile increases, the lift due to the air flow increases. As a result, the frictional force between the tire and the ground significantly decreases and the stability remarkably lowers. Therefore, the spoiler mounted on the automobile has an inclination angle There is a need to fluctuate.
