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...

specific Embodiment approach

[0024] DETAILED DESCRIPTION: The present invention provides an air guiding device applied to a van trailer. The van trailer 3 includes two sides, a top surface and a rear door, and is towed to work on the first car body 2. On the rear side, a tractor is formed. The air diversion device includes a tailgate diversion device 7 installed on the rear door of the van trailer 3. The tailgate diversion device 7 includes a diversion device I and a diversion device II. The upper end surface of the flow device I and the top surface of the van trailer 3 are arranged at an included angle, and the outer side surface of the flow guide II and the side surface of the van trailer 3 are arranged at an included angle.

[0025] In this embodiment, the flow guiding device I includes an upper left guiding device 72 and an upper right guiding device 74. The upper left guiding device 72 and the upper right guiding device 74 each include an upper air guiding plate 721, a fixed connecting rod III 722, The...
