摘  要
　　　近年來，隨著我國的高速公路的迅速發(fā)展，貨物的廂式運輸不斷增加，廂式汽車在專門運輸和專項作業(yè)中的優(yōu)越性也越來越明顯，用戶對廂式汽車優(yōu)越性的認識逐漸加深，對其需求也日益增加。隨著國民經(jīng)濟的持續(xù)快速增長，我國廂式汽車市場進入了快速成長期，今后我國廂式運輸車的需求量將更迅猛地增加。
　　　本文首先根據(jù)汽車總布置的要求，對廂式貨車的特點以及國內(nèi)外發(fā)展狀況都做了相關(guān)的概述。然后選擇整車和各總成的結(jié)構(gòu)型式，對各個主要技術(shù)特性參數(shù)和性能參數(shù)進行相關(guān)的設(shè)計和計算，使各總成有機地組合在一起，形成一個完整的整車概念，并保證所設(shè)計的汽車具有良好的技術(shù)性能。

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.
