Abstract
Based on leaf spring suspension, the arctile conduct an overall design and calculation. At first, take the structure of Gonow pickup suspension as reference, confrim the main structure of this design.Then carry on a detailed design and calculation of suspension for the elastic component and shock absorber.At the same time, analyse and calculate the whole trajectory and angle of suspension. Finally ,using CATIA software to carry though a three-dimensional modelingand on leaf spring suspension.On the other hand, leaf spring suspension have many advantages,like simple structure, low cost, reliable work and so on, it is used widely in various large and medium-sized vehicles.
