The invention discloses an air flow assistance adjusting device, which comprises two empennage structures, air flow channels and a hydraulic pipeline, wherein the empennage structures are located at the tail ends of the air flow channels. Each empennage structure comprises a main wing, an aileron and a driving mechanism, wherein the main wing is located below the aileron, the front end of the aileron is close to the tail end of the main wing, the middle part of the upper board surface of the main wing is provided with a positioning plate which is fixed relative to the main wing, the upper end of the positioning plate is rotatably connected with the aileron, the driving mechanism comprises an aileron cylinder, a rotating auxiliary cylinder and a base used for positioning the rotating auxiliary cylinder, and a body of the aileron cylinder is rotatably connected with the positioning plate. The hydraulic pipeline comprises a hydraulic pump, an aileron pipeline used for switching the two aileron cylinders and a rotating auxiliary pipeline used for independently switching each rotating auxiliary cylinder. The invention aims to provide a device which can adjust a down force and air resistance at the left side and the right side of a tail part of an automobile, thereby improving the adhesion performance of the automobile, and reducing the tire load.
