Abstract

An object of the present invention is to provide a rectifying device that prevents deterioration of air resistance caused by airflow passing through the inner diameter side of a wheel rim. A rectifying device arranged in a vehicle (1), the vehicle (1) comprising: a wheel (W) having a tire (T) and a rim (R); a housing (41) provided with a rotatably supported wheel and the lower arm (52), which is respectively connected to the lower part of the vehicle body and the lower part of the shell in a swingable manner, and extends approximately along the vehicle width direction, wherein the rectification device includes an inner side deflection unit (70), which is arranged on the lower The arm deflects the airflow flowing in from the front side of the vehicle to increase the velocity component of the airflow inward in the vehicle width direction.

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 wheel rim. 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] Conventionally, various rectification devices have been proposed that rectify the air flow to improve the desired performance of the vehicle. [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 desc...
