This discourse select and count the layout design and the relevant parameter of the chassis`s main parts of Zhong Shun light bus , On the basic of this , we finally finish ed this layout design , select ing the form of the layout design , and then we need to ensure the number of shaft s、 the type of drive and the mounted position of engine . And then , with the ensure the form of the chassi s overall layout , take into account fort of the bus and the basic capability need of mercial vehicle , to selec t and count the parameter of the main size and the capability . With the basic select and ensure every the chassis`s parts , such as power assembly , Shock Absorber , steering and soon. At last consult the chassi s layout project of homogeneous model of the car ,to make the layout of the Zhong Shun light bus`s chassi s, and protract the chart of the chassi s overall layout . On the course of the design of the chassi s, in order to make sure fort and the safety of the automobilism , we check the interference movement to the steering system . On the course that we use the graphical method, check the different case when the steering system turn left or right .The analysis reault indicate that all the design of the steer ing systerm are matching with reason and practicableness . Key words : light bus; chassis ; layout ; check the otion 充值下载即送 CAD 图纸, QQ 363
