Deformable tailfin system

Abstract

The invention discloses a deformable tailfin system which comprises two tailfin structures, airflow channels and hydraulic pipelines. The tailfin structures are arranged at the tail ends of the airflow channels, and each tailfin structure comprises a main fin, an auxiliary fin and a drive mechanism, wherein the main fin is located below the main fin, the front end of the auxiliary fin is close to the tail end of the main fin, the ends of the same sides of the main fin and the auxiliary fin are both provided with an end plate, the main fin is fixedly connected with the corresponding end plate, and the auxiliary fin is rotatably connected with the corresponding end plate. Each drive mechanism comprises an auxiliary fin cylinder and a base, wherein a rotation auxiliary cylinder is arranged on the base. Each hydraulic pipeline comprises a hydraulic pump, an auxiliary fin pipeline and a rotation auxiliary pipeline, wherein the auxiliary fin pipeline is used for connecting or disconnecting the two auxiliary fin cylinders at the same time, and the rotation auxiliary pipeline is used for switching on or switching off each rotation auxiliary cylinder independently. Multiple parallel strip-shaped through holes are formed in the front side of each end plate and located above the corresponding auxiliary fin. The deformable tailfin system can adjust the down force and air pressure on the left side and the right side of the tail portion of an automobile, so that the adhesion property of the automobile is improved, and the tire load is lowered.

Description

technical field [0001] The invention belongs to the field of automobiles, in particular to a deformable tail system. 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 of the aircr...

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
