First is to the massive electric automobile material consult, then from the electrical machinery choice, the battery choice begins, according to the topic request, carries on a series of computations finally to obtain satisfies the travel request the electrical machinery and the battery. After chooses the electrical machinery and the battery, is same with the design fuel oil automobile chassis, and simultaneously synthesizes the electric automobile the unique feature, to the automobile transmission system, the travel system, the steering system, the braking system carries on 11 analyses and the design. Designs the chassis in this for the electric automobile in the process, must pay attention to the electric automobile and the fuel oil automobile different place specially. Designs in me on this low speed tourism electric automobile, its power transmission is very simple, does not have the traditional coupling and the transmission gearbox, also does not have the rotary transmission system, is the electrical machinery direct and the main gear box with the gear meshing direct connection, like this causes the entire chassis the spatial big increase, the entire chassis arrangement also might change is more free. Finally in these foundations, the use computed information, carries on to the automobile always arranges the design. KEY WORDS: pur
