Abstract
The invention aims at providing a fairing used for preventing air drag increase caused by an airflow on the inner diameter sides of wheel rims. The fairing is arranged in a vehicle (1); the vehicle (1) comprises wheels, shells (41) and lower arms (52), wherein each wheel is provided with a tire (T) and a rim (R), the shells (41) are provided with hub bearings rotationally supporting the wheels, and the lower arms (52) are in swing connection with the lower portion of a vehicle body and the lower portions of the shells and extends roughly in the vehicle width direction. The fairing comprises air jet units (60), and the air jet units (60) are arranged on the front sides of the wheels and used for jetting air to form an airflow (S1) in the areas of the lower arm sides of the wheels, wherein the airflow (S1) flows obliquely relative to the front-and-back direction of the vehicle in the manner that the downstream side becomes a vehicle-width-direction inner side relative to the upstream side.
Description
technical field [0001] The present invention relates to a rectifying device for rectifying the airflow around the wheel of an automobile, and more particularly to a rectifying device for preventing deterioration of air resistance caused by the airflow passing through the inner diameter side of the rim of the wheel. Background technique [0002] Automobiles such as sedans generate an airflow (so-called running wind) that flows around the vehicle body when the vehicle is running. [0003] Various rectifying devices that rectify this air flow to improve the desired performance of the vehicle have been proposed so far. [0004] As a prior art related to a rectifying device provided in a vehicle, for example, Patent Document 1 describes that in order to cool the wheel brakes, an air guide element is provided on the wheel control arm of the suspension, and the element is arranged so as to form an angle of attack with respect to the air flow. . [0005] Patent Document 2 describe...
