摘 要
隨著國民經濟快速增長，人民物質生活水平的不斷提高，國內公路網(wǎng)絡越來越發(fā)達，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)人都住在農村，經濟發(fā)展水平很不平衡，隨著城市化進程的加快，以及我國逐步步入老齡化社會，這些事實都預示著這樣一個結果：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。為滿足國內市場的需要，適應用戶對經濟、環(huán)保客車的需求，并在對國內市場進行調研的基礎上，設計和開發(fā)出這款中型客車。
中型客車按中型中級標準設計，主要用于城鄉(xiāng)之間公路客運。設計為36+1座，最大滿足第三類車型的座椅要求，提高客車營運的經濟性。中型客車的開發(fā)思路是側重于經濟性、實用性和可靠性，利用S5B底盤進行設計，設置大容量油箱及規(guī)格行李倉（3.30立方米），車內采用軟裝飾減震消音材料，實現(xiàn)車內空間寬敞。在適應用戶需要及法規(guī)要求的前提下，合理選擇各總成配置及結構設計，盡量采用通用結構，通過降低成本和提高客車經濟性增加市場競爭力。本論文簡要地介紹了此中型客車的設計目的，主要的結構特點、參數(shù)和技術參數(shù)。
關鍵詞 長途汽車，結構參數(shù)，技術參數(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.
