The Design of Bus DoorAbstract In people's daily life,bus has become an increasingly important part.Itcan be said that the bus has become a necessary means of transportation for thedaily travel of modern young people.Especially for young people in big cities,theyhave a certain sense of environmental protection.When their own funds areinsufficient to support the purchase of cars,buses become the best choice for them totravel because of their convenience,environmental protection and cheapness.In thispaper,after consulting a large number of references,through the analysis andresearch of the structure of each component of the double inner swing door of the bus,as well as the power and driving system of the inner swing door,the structure of theseal and the door pump is finally designed.In addition,some important accessories inthe inner pendulum besides the main components are selected,screened and set up.At the same time,the falling off of the door axle is designed and improved.Afterinvestigating and researching the design of internal swing door,we summarize andcompare the design of relevant buses at home and abroad,in order to find theshortcomings in this area in our country,and improve it,which is also the designsignificance of this bus door.The knowledge involved in bus door design is not onlyrelated to ergonomics,mechanical structure engineering and fluid mechanics,butalso involves the research of mechanical engineering among these prerequisiteknowledge.The whole design will include the overall economy and technology.Keywords:inner swinging door;transmission mechanism;driving system
