Automobile rear diffuser structure

Abstract

The invention discloses an automobile rear diffuser structure which comprises two rear wing structures, an airflow channel and a hydraulic pipeline. The empennage structures are located at the tail end of the airflow channel. Each rear wing structure comprises a main wing, an auxiliary wing and a driving mechanism, wherein the main wing is located below the auxiliary wing, the front end of the auxiliary wing is close to the tail end of the main wing, and the same side ends of the main wing and the auxiliary wing are each provided with an end plate; each main wing is fixedly connected with the corresponding end plate, and each auxiliary wing is rotationally connected with the corresponding end plate; and the middle of each main wing is provided with a rotating plate parallel to the corresponding end plate, and the other end of each rotating plate is hinged to the corresponding auxiliary wing. Each driving mechanism comprises an auxiliary wing cylinder and a base. A rotating auxiliary cylinder is arranged on each base. The hydraulic pipeline comprises a hydraulic pump, an auxiliary wing pipeline and a rotating auxiliary pipeline. A plurality of parallel strip-shaped through holes are arranged at the positions, on the front side of each end plate, of the corresponding auxiliary wing. According to the automobile rear diffuser structure, a deformation rear wing system which can adjust downward pressure and air resistance on the left and right sides of the tail of an automobile so as to improve the attachment performance of the automobile and reduce tire loads is provided.

Description

technical field [0001] The invention belongs to the field of automobiles, in particular to an automobile rear diffuser structure. 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 opposite to that...

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
