摘要
乘客门是客车的重要组成部分,是乘客上下车的通道,对客车的整体造型也起着
重要的协调作用。随着我国汽车技术的发展,在长途车中我国汽车厂家已普遍采用了
优势突出的外摆式乘客门。外摆式乘客门是一种无轨道的移出车门,门扇靠回转
臂支撑,依靠转轴的转动带动门扇作近似于平行移动的运动,因而也称为平移门。
本文兼容外摆式乘客门和发动机舱门的设计。分析了外摆式乘客门和发动机舱门
的工作原理以及其各部分的尺寸和一些主要零件的选型和安装。讨论了国内外客车附
件工业的发展状况的比较。本次设计应用了 CAD 进行设计外摆式乘客门和发动机舱
门. 
关键词:外摆门,发动机舱门,CAD。

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 ponents 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
