ABSTRACT
The design specification under the demand , from reality , full considering of the overall vehicle shape to achieve the overall chassis layout optimization. Vehicle chassis is an important part of the car, it can support and installate the engine and its components, format the overall shape of the car and accept the engine’s driving force, make the vehicle safty. The core technology of passenger. Vechicle manufucturing is chassis technology. This passage is a description of the vehicle chassis layout and the total number of bus performance parameters. Chassis layout including the engine, cluth, transmission,and so on.performance parameters including power, fuel e economy. The design of car through the choice of the form of, car main parameters selection, chassis layout mainly includes the engine, the clutch, the transmission of choice. Simultaneously the dynamic performance and fuel economy calculation, etc. Through the calculation choice to identify various parts of the model, the general arrangement of the draw.
KEYWORDS: Medium-sized truck, Chassis layout, Power performance, Fuel economy
