The reference design similar models on the basis of the motor vehicles suspension and steering system design methods, Actually oriented functions, a reasonable lower manufacturing costs. First select a steering system and suspension structure, according to the 3 ton truck used in specific circumstances, with the design requirements, determining perspective shift﹑turning radius to form and the structure of devices to all parts of the structure and strength. Suspension structure﹑main parameters﹑oriented institutions﹑absorber and spring﹑horizontal stabilizer design. So that suspension and steering system meet the performance 3 ton truck. The steering system so that the suspension and re-balance between power and fuel economy on the basis of rational choice of the structure, make a reasonable size, the layout is easy to install. But can be used for other models, have a broad prospect。 KEY WORDS : steering system, suspension, recirculating ball , hydraulic 3
