Abstract
By analysing and calculating the failure mode on heavy vehicle clutch,The paper has concludes that the main reason of failure mode on heavy vehicle clutch is the small slip work per auto friction area.We can adopt a series of measures to make slip work per auto friction area bigger than allowed value when vehicle strats,and then radically solve the problem of clutch burning,it contain consulting some datas konwn,choosing chutch's improving plan by compare,optimizing the parameters of cluth disc,accretion of the friction area of clutch.In order to simply manufacture,the driving means of platen using passing force slice.At the same time, the platen springs adopt diaphragm spring, so vehicles start more steadily ,the load of powe train decreases,all of these make for extending the useful life of vehicle and engine.
