Automobile tail part double-turbulence device

Abstract

The invention discloses an automobile tail part double-turbulence device, which comprises two tail wing structures, an air flow channel and a hydraulic pipeline, wherein the tail wing structure is located at the tail end of the air flow channel and comprises a main wing, an aileron and a driving mechanism, the main wing is located below the aileron and provided with a plurality of upward extending aileron positioning plates, the upper ends of the aileron positioning plates are hinged with the tail end of the aileron, the front end of the aileron is close to the tail end of the main wing, the middle part of the main wing is provided with a rotating plate which is vertically arranged and can rotate relative to the main wing, the other end of the rotating plate is hinged with the aileron, the driving mechanism comprises an aileron cylinder and a base, the base is provided with rotating auxiliary cylinders, and the hydraulic pipeline comprises a hydraulic pump, an aileron pipeline and rotating auxiliary pipelines used for independently switching each rotating auxiliary cylinder. The invention aims to provide a device which can regulate down pressure and air resistance at the left side and the right side of an automobile tail part so as to improve the automobile adhesion performance and reduce the tire load.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to a double spoiler device at the rear of a vehicle. 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 i...

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
