This article is designed to design the front and rear suspension of light , it designs the scheme of whole car based on the parameters which were already been given,and selects the main parameters of the car,Including the size parameters, quality parameters and main performance on pletion of automotive Design,it analysis the structural characteristics and type of suspensions, choose the types of suspensions for front and rear chooses the McPherson independent suspension for front suspension,and the Oblique single arm for rear on the suspension of the performance parameters of selection, and plete suspension of the structural elements of the design calculation,including the coil spring, shock absorber, oriented institutions, horizontal stabilizer bar and so spring's design and calculation, including the stiffness and strength of the check, make the design of the spring biasing to meet the design requirements. For the front and rear suspension matched shock absorber, damper size calculation parameters, and test whether the shock absorber t
