An air guiding device applied to a van trailer

Abstract

The invention provides an air guiding device applied to a van trailer. The air guiding device comprises a tail door guiding device installed on a rear compartment door of the van trailer. The tail door guiding device comprises a guiding device body I and a guiding device body II. An included angle is formed between the upper end face of the guiding device body I and the top face of the van trailer. An included angle is formed between the outer side face of the guiding device body II and the side face of the van trailer. The air guiding device further comprises rear lower side guiding devices,side face guiding devices and front lower portion guiding devices, all of which are installed on the lower side of a compartment of the van trailer. The rear lower side guiding devices are symmetrically arranged on the left side and the right side of the rear portion of a trailer frame of the van trailer, the side face guiding devices are symmetrically arranged on the left side and the right sideof the middle portion of the trailer frame of the van trailer, and the front lower portion guiding devices are symmetrically arranged on the left side and the right side of the front portion of the trailer frame of the van trailer. The air guiding device is reasonable in design, surrounding air flows of the van trailer can be orientated and guided in sequence, the possibility that turbulence cyclones and flow separation are generated around the van trailer through the air flows is reduced, air resistance is reduced, and the air guiding device is low in carbon, environment-friendly and worthy of popularization.

Description

Technical field [0001] The invention relates to the technical field of air drag reduction, in particular to an air guide device applied to a van trailer. Background technique [0002] When a heavy-duty traction train is running at high speed, about 25% of the wind resistance is distributed in the first car body part, and about 60% to 75% is distributed in the van trailer part. The aerodynamic wind guide simply assembled by the main tractor cannot be effective. Only by reducing the wind resistance of the traction train and reducing the wind resistance of the trailer system can the wind resistance of the traction train be more effectively reduced. Especially for the logistics transportation vehicles that have more high-speed road conditions for lightly thrown goods, their vehicle load is small, rolling resistance and acceleration resistance account for a relatively small proportion, and air resistance accounts for a relatively high proportion. At present, semi-trailer vehicles for...

AI Technical Summary

Problems solved by technology

At present, road logistics transport semi-trailers generally do not have air guide devices, tires and tool boxes are exposed to the driving airflow, and the air resistance on the rear side of the box is relatively large, resulting in high fuel consumption, and the vehicles are not environmentally friendly.
