Abstract

The invention relates to the technical field of automobile energy saving and emission reduction, and specifically discloses a bionic heavy truck pneumatic damping device. The pneumatic damping deviceis installed between a tractor and a trailer. The pneumatic damping device includes a connecting surface, a rectifying surface and two side faces, the connecting surface is fixed on the side, near thetractor, of the trailer, the rectifying surface includes an outward convex surface, an inward concave surface and a tail extension surface, the outward convex surface is located above the inward concave surface, and the outward convex surface is tangent to the top surface of the trailer. By means of the pneumatic damping device, flow separation of air flow on the top of a container of the traileris weakened, the separating area is reduced, the drag reduction efficiency of the entire vehicle is as high as 15%, and an effective rectifying effect is achieved.

Description

technical field [0001] The invention relates to the technical field of energy saving and emission reduction of automobiles, in particular to a bionic aerodynamic drag reduction device for heavy trucks. Background technique [0002] When a heavy-duty truck is running at high speed (speed greater than 80km / h), due to its large size and large windward area, the aerodynamic resistance of the whole vehicle is relatively large when driving at high speed. The aerodynamic resistance accounts for more than half of the total driving resistance, and the driving stability is relatively high Therefore, it is particularly important to design an effective aerodynamic drag reduction device. At present, countries such as Europe and the United States generally adopt fairing technology to improve the aerodynamic characteristics of heavy-duty trucks and reduce air resistance, thereby achieving the purpose of reducing fuel consumption and emissions during vehicle operation and improving driving ...
