Device for adjusting down force of automobile

Abstract

The invention discloses a device for adjusting the down force of an automobile. The device comprises two spoiler structures, a lifting channel and a hydraulic pipeline. Each spoiler structure is located in the lifting channel and comprises a main wing, an auxiliary wing and a driving mechanism capable of driving the main wing to rise and fall and driving the auxiliary wing to rotate, 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, end plates are arranged at the ends, on the same side, of the main wing and the auxiliary wing, the main wing is fixedly connected with the corresponding end plate, and the auxiliary wing is connected with the corresponding end plate in a rotary mode; the driving mechanism comprises a main wing cylinder, an auxiliary wing cylinder and a base, and a rotation assisting cylinder used for driving the main wing and the auxiliary wing to rotate relative to the base at the same time is arranged on the base. The hydraulic pipeline comprises a hydraulic pump, a main wing pipeline, an auxiliary wing pipeline and a rotation assisting pipeline. By the adoption of the device, the down force and air resistance on the left side and right side of the tail of the automobile can be adjusted so as to improve the adhesion property of the automobile and reduce tire loads.

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
