If transversal leaf spring loaded design and calculation, horizontal designed to guide agencies conducted smoothly and analytical, Wang squatting length calculation and shock absorber design. The kei is belong to passenger car, but people regard its suspension as carriage suspension because of the kei widely applying to business mute and urban logistics, etc .Training is a perfect car for the car more difficult to achieve fuel, because it is necessary to meet the suspension of vehicle fort, but also meet the requirements of the stability of its manipulation, and these two aspects are mutually antagonistic. For example, in order to achieve good sexual fort, require a significant buffer car shock, which is designed springloaded soft farther, but the springloaded soft but easy to vehicle braking occurred nod and accelerate the rise and so serious adverse trends, to the detriment of the vehicle to easily lead to vehicle instability manipulation. How to handle the relationship between these areas before our designers have to face the problem .So if these meet the mission to design a harmonious suspension of a growing number of vehicles involved will bring great benefits. They will understand their outstanding suspension to the fort of a good, and safe smoothly. I hope the design can satisfy all requirements. It is creativity of the design that it uses transversal leaf spring instead the coil spring at the Macpherson type of independent, to solve the problem of kei that lateral rigidity. The design drawings pleted mainly by puter mapping, puter archiving, typesetting, printing out maps and papers. Also pleted a number of English translation work.
