摘 要
隨著國民經(jīng)濟(jì)快速增長，人民物質(zhì)生活水平的不斷提高，國內(nèi)公路網(wǎng)絡(luò)越來越發(fā)達(dá)，人們出行對安全、舒適的高性能客車需求日益增長。但我國的大多數(shù)人都住在農(nóng)村，經(jīng)濟(jì)發(fā)展水平很不平衡，隨著城市化進(jìn)程的加快，以及我國逐步步入老齡化社會，這些事實(shí)都預(yù)示著這樣一個結(jié)果：發(fā)展中低檔城鄉(xiāng)間的中型客車在我國有很大的優(yōu)勢。為滿足國內(nèi)市場的需要，適應(yīng)用戶對經(jīng)濟(jì)、環(huán)?？蛙嚨男枨螅⒃趯鴥?nèi)市場進(jìn)行調(diào)研的基礎(chǔ)上，設(shè)計和開發(fā)出這款中型客車。
中型客車按中型中級標(biāo)準(zhǔn)設(shè)計，主要用于城鄉(xiāng)之間公路客運(yùn)。設(shè)計為36+1座，最大滿足第三類車型的座椅要求，提高客車營運(yùn)的經(jīng)濟(jì)性。中型客車的開發(fā)思路是側(cè)重于經(jīng)濟(jì)性、實(shí)用性和可靠性，利用S5B底盤進(jìn)行設(shè)計，設(shè)置大容量油箱及規(guī)格行李倉（3.30立方米），車內(nèi)采用軟裝飾減震消音材料，實(shí)現(xiàn)車內(nèi)空間寬敞。在適應(yīng)用戶需要及法規(guī)要求的前提下，合理選擇各總成配置及結(jié)構(gòu)設(shè)計，盡量采用通用結(jié)構(gòu)，通過降低成本和提高客車經(jīng)濟(jì)性增加市場競爭力。本論文簡要地介紹了此中型客車的設(shè)計目的，主要的結(jié)構(gòu)特點(diǎn)、參數(shù)和技術(shù)參數(shù)。

ABSTRACT
Nowadays our China has a very quick increasing of economy and the quality of life of we Chinese has improved rapidly, and the net of highway is forming day by day, thus the traveling people’ requirements of safe and comfortable coach is also increasing day by day. But the truth is that the majority of people live in countryside, the economic level is imbalance. For another, there is a trend of forming city in China and our society will have more and more old people. All these facts predict that semi-low coach will have a superiority in domestic market. In order to meet the demand of economic and ‘green’ coach in our market, we design EQS5B coach in terms of study domestic market.
We design EQS5Bby the standard of middle-class and aiming to travel these people from city to country. The coach has 36+1 seats and trys to satisfy the demand of class 3 style’ requirements for its seats and hit the target of ‘low price’. The principle of design this coach is to have more economic and practicality and reliable characters. Our chassis is EQS5Band we try to equip fitting gasoline tank and baggage box (nearly 3 stere). We have flexible material to decorate the inner of coach body and try to achieve an abundant space inside the coach. We make great effort to use current configuration and enhance our competitive ability by the way of decreasing price and making more economic character of the coach. This paper briefly introduces the design purposes, main structure characteristics and technical parameters about EQS5B coach.
