设计简介
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。
本文为兼容残疾轮椅中型客车车门设计，包括外摆式乘客门和旋转式车门的设计。分析了外摆式乘客门和旋转式车门的结构和工作原理，确定其各部分的尺寸及主要零部件的选型及安装。讨论了国内外汽车附件工业发展的情况比较。在本设计中应用了CAD软件制作前后乘客门。
关键词： 外摆门，旋转门，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 door of a medium-sized passenger car which permit a disable and sick wheel chair . Include the design of the outer turning service door and the the swing door. Analyzed the structure and operating principles of the outer turning service door and the swing 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 front and back passenger's door.
