Air flow assistance adjusting device

Abstract

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.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to an airflow assist regulating device. Background technique [0002] During the driving process of the car, due to the shape and structure characteristics of the car itself, the car will generate an upward lift when driving, and the adhesion between the car and the ground will decrease. When the car is running at a high speed, this phenomenon is more prominent. In order to alleviate the negative impact of lift on the driving stability of the car as much as possible, designers often start from the shape of the car and optimize the shape of the car to reduce the lift generated. In addition, on high-performance cars, sports cars or racing cars, in order to improve the adhesion of the car to the ground when cornering, a front wing or tail will be installed on the head or tail of the car. The cross-sectional shape of the wing is similar, but its installation method is just opposi...

AI Technical Summary

Problems solved by technology

[0003] In the actual driving process, especially in the case of high-speed curves, the car will have a tendency to roll to the outside of the curve due to the centrifugal effect, and the positive pressure on the tires located on the inside of the curve is reduced, while the tires on the outside of the curve The positive pressure on the tires increases, and the car has a large roll, which will easily cause the car to break through the adhesion limit of the outer wheel of the curve and slip.

However, since the front and rear wings exert the same downforce on the left and right sides of the car, it is still difficult to alleviate this situation
