摘要
乘客門是客車的重要組成部分，是乘客上下車的通道，對(duì)客車的整體造型也起著重要的協(xié)調(diào)作用。隨著我國汽車技術(shù)的發(fā)展，在長途車中我國汽車廠家已普遍采用了優(yōu)勢突出的外擺式乘客門。外擺式乘客門是一種無軌道的移出車門，門扇靠回轉(zhuǎn)臂支撐，依靠轉(zhuǎn)軸的轉(zhuǎn)動(dòng)帶動(dòng)門扇作近似于平行移動(dòng)的運(yùn)動(dòng)，因而也稱為平移門。
本文兼容外擺式乘客門和發(fā)動(dòng)機(jī)艙門的設(shè)計(jì)。分析了外擺式乘客門和發(fā)動(dòng)機(jī)艙門的工作原理以及其各部分的尺寸和一些主要零件的選型和安裝。討論了國內(nèi)外客車附件工業(yè)的發(fā)展?fàn)顩r的比較。本次設(shè)計(jì)應(yīng)用了CAD進(jìn)行設(shè)計(jì)外擺式乘客門和發(fā)動(dòng)機(jī)艙門.
關(guān)鍵詞：外擺門，發(fā)動(dòng)機(jī)艙門，CAD。
Abstract
Passenger door is the important department of the coach, is the route way for the passengers. And assort with the whole coach sculpt. With the development of our vehicle technology, the domestic vehicle factory has already adopted the outer turning service door. It has much more predominance. The outer turning service door is the door which has no tram road and parallel move out of the coach, the door was supported by the circumrotate arm. By the rotation of the circumrotate axes, the door is moving close to the parallel move. Thus this door is called translation door.
This paper introduces the design of the outer turning service door and the Engine cabin door. Analyzed the structure and operating principles of the outer turning service door and the Engine cabin door, determined the size of its parts and major components of the models and installation. Discussed the development of the vehicle annex industry. Application in this design the CAD software create in the outer turning service door and the Engine cabin door.
Key word: the outer turning service door, the Engine cabin door,CAD
