Abstract
In recent years, as China's rapid development of highway, the transportation of goods has increased, the superiority of van transportation in the special transport and special operations has also become increasingly obvious. The consumers have more and more known the superiority of van, and their requirement of van also increase day by day.
With the national economy continued to grow rapidly ￡?our market of van in China has entered a rapid growth stage, and in the future the demand for van will increase tremendously in china.
In this paper, in accordance with the requirement for the layout of vehicle, I first gave a general overview of the features and the development both at home and abroad of van. Then, I selected the structure of the vehicle and each assembly, and made design and calculations of the main technical characteristics of the various parameters and performance parameters, in order to let every assembly combine into a unified or integrated whole, at last the van own good technical performance.
