Abstract
    
    In today's society, the development of the automobile industry is affecting the development of the national economy, and the progress of human being can not be separated from the development of the automobile industry. In the global economic development environment, China's various industries are affected by the advanced technology of other countries at the same time, more and more foreign enterprises and brand spread to China has become a reality. Under the impetus of new market demand, it is urgent to improve and optimize the front air suspension. The production of truck air suspension of the enterprise, must give full consideration to the problems that may appear in the truck front air suspension operation, try to make the truck before the standardization of the air suspension, the higher the better, stability and strength is getting better and better, the domestic truck before R & D and manufacturing of air suspension to consistent with the call for a global firm, stable performance theme. The development of front air suspension is closely related to the progress of human society and the level of science and technology.
    The topic of this graduation design is the truck front air suspension assembly design, through the design of the truck front air suspension assembly, to understand its structure and working principle, and the optimization, makes the design of truck front air suspension assembly structure more reasonable and more secure.
