Automobile downward pressure adjusting device

Abstract

The invention discloses an automobile downward pressure adjusting device which comprises two tail wing devices, an airflow channel and a hydraulic pipeline. The tail wing devices are located at the tail end of the airflow channel. Each tail wing device comprises a main wing, an auxiliary wing and a driving mechanism, wherein the main wing is located below the auxiliary wing, a plurality of upward-extending auxiliary wing positioning plates are arranged in the middle of the main wing, the upper ends of the auxiliary wing positioning plates are hinged to the tail end of the auxiliary wing, and the front end of the auxiliary wing is close to the tail end of the main wing; and a vertically-arranged rotating plate capable of rotating relative to each main wing is arranged in the middle of each main wing, and the other end of each rotating plate is hinged to the middle of the corresponding auxiliary wing. The driving mechanism comprises a main wing cylinder, an auxiliary wing cylinder, a rotating auxiliary cylinder and a base. The hydraulic pipeline comprises a hydraulic pump, a main wing pipeline, an auxiliary wing pipeline and a rotating auxiliary pipeline. According to the automobile downward pressure adjusting device, air resistance and downward pressure on the left and right sides of the tail of an automobile can be adjusted, so that the adhesion property of the automobile is improved, and tire loads are lowered.

Description

technical field [0001] The invention belongs to the field of automobiles, in particular to an automobile downforce 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 opposite to ...

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
