This design mainly studies about the medium vans transmission and the universal transmission between axles.It is based on universal transmission device structure and working principle, and calculates the universal shaft and the reasonable structure by finite element analysis, theoretical research , practical research, the qualitative and quantitative analysis. Use text and illustrations method combining describes the structure ,universal transmission device and selected basic dimensions. Then calculate the torque, and compare the bending stress and shear stress intensity of universal shaft and the roots of the neck. Use application of the finite element analysis method in stress analysis of intermediate shaft transmission and mapped the stress contours. The cross axis needle bearing on contact stress and needle roller can withstand the maximum load calculation for the use of spiders. Compare the cardan shaft supporting the role of the reverse force, cardan sustaining bending and torque load test, in order to achieve intensity. To ensure the service life be longer by normal use in the circumstances.</p><p>Key words: medium truck；universal driving device；cardan universal joint；slip join</p><p>目錄</p><p>緒論<span
