Abstract

The invention discloses a drag reduction device for vans. The device comprises a closed bionic flow guide cover arranged between the cab of the van and the cargo compartment, a drag reduction device arranged at the rear of the van, and a bionic non-smooth surface structure arranged on the two side surfaces of the van body. By the method, the wind resistance of the van can be reduced, the vehicle speed can be increased, the vehicle stability can be increased, and the fuel consumption can be reduced during the running of the van.

Description

technical field [0001] The invention relates to the technical field of van trucks, in particular to a drag reducing device for van trucks. Background technique [0002] Judging from the shape of the existing van, the van is higher than the cab of the tractor and has a large windward area, resulting in poor aerodynamic characteristics of the vehicle, large aerodynamic resistance, poor economic performance, and poor driving stability. Difference. With the rapid increase of the speed of the van, the above-mentioned shortcomings of the van are becoming more and more prominent. The higher the speed of the van, the proportion of the aerodynamic resistance proportional to the square of the speed in the total resistance of the van The larger the ratio, the greater the fuel consumption. Contents of the invention [0003] In view of this, the object of the present invention is to propose a drag reducing device for a van, which can reduce wind resistance, increase vehicle speed, ...
