This paper deals with the design of clutch and universal joint shaft. The clutch is assembled in which the power train directly connecting with engine. Its primary functions are: switch off and transfer power for train in order to guarantee to connect smoothly engine to power train when automobile is starting. Then automobile may start smoothly; make engine away from power train and reduce the impact among the gears when the transmission shift; restrict the maximal torque that power train can endure when it come in for larger dynamic load; reduce effectively vibration and roar of the power. Universal joint shaft is used to two shaft configuration difference in every minute. It can transfer torque from transmission to Trans axle, and turning movement; It also can match the two shaft have the same movement. Because of the card a joint angle which produce additional load, chatter phenomena and voice should limit and it can’t produce resonance in general movement. With people expect better clutch and universal joint shaft base an the design spirit of keeping improving. Through contrast of various precepts choice and majority of the parameter, finally I adopt the pushing diaphragm spring disc spring clutch, the hydrostatic controls and universal joint shaft, In order to scheme out better clutch and shaft which is congress step with trend of automobile development. I will try my best to create new structure in some components. KEY WORDS: Diesel SUV，new automobile， start smoothly， maximal to torque，diaphragm spring disc，universal joint shaft IV
