Description

Technical Field

[0001] This utility model relates to the field of aerodynamic components for commercial vehicle bodies, and in particular to an N2 type automotive fairing that is easy and quick to install and remove. Background Technology

[0002] The fairing on the top of the cab of an N2 category truck is a key component for reducing wind resistance and improving fuel economy. Its installation efficiency directly affects the overall vehicle maintenance cost. Currently, the mainstream fairing adopts a direct bolt connection installation design on the top of the cab. Its installation point is located inside the fairing and is blocked by the cargo box or cargo box. Disassembling and installing the fairing requires first removing the cargo box or cargo box. However, removing the cargo box requires two people to work together, which is time-consuming and increases maintenance costs. The installation point is located inside the fairing, and the connection operation requires going deep into the narrow space, which is inconvenient. Utility Model Content
