Vehicle tail aerodynamics assistance device

Abstract

The invention discloses a vehicle tail aerodynamics assistance device which comprises two tail wing structures and a driving mechanism, wherein the two tail wing structures are symmetrically arranged on the left and right sides of the vehicle tail; the tail wing structures comprise upper wing pieces, lower wing pieces, bottom plates and end plates; the front ends of the lower wing pieces and the rear ends of the upper wing pieces are respectively rotationally connected with the end plates; two ends of the bottom plates are respectively fixedly connected with the end plates; the driving mechanism comprises first hydraulic cylinders, second hydraulic cylinders and third hydraulic cylinders; the first hydraulic cylinders are used for pushing the tail wing structures to lift up and down; the second hydraulic cylinders are used for pushing the tail wing structures to rotate back and forth; the third hydraulic cylinders are used for adjusting the relative opening / closing angles between the upper wing pieces and the lower wing pieces; and the device also comprises a hydraulic pump, a first pipeline acting on the two first hydraulic cylinders, a second pipeline acting on the two second hydraulic cylinders, and a third pipeline acting on the two third hydraulic cylinders. The invention aims at providing a vehicle tail aerodynamics assistance device. According to the device, the lower pressure and air resistance on the left and right sides of the automobile tail can be adjusted, so that the automotive adhesion performance is improved, and the tire load is reduced.

Description

technical field [0001] The invention belongs to the field of automobiles, in particular to an auxiliary steering aerodynamic kit for automobiles. 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. Similar, but its installation method is just opposite to that of an airplane wing. Wh...

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, this is still difficult to mitigate as the rear wing exerts the same amount of downforce on the left and right sides of the car
