Abstract:

Multi-plate wet friction clutch is one of key components of duty truck hydrodynamic-mechanical transmission. Super-heated burn and warping deformation are main invalidation forms of wet friction clutch. It is one of effectual methods to augment friction coefficient and prolong natural life of wet friction clutch that friction disks’ surface temperature and radial temperature are reduced. Compute method of friction disk surface temperature is obtained using theory analysis and confirmed correctness using finite element analysis. It is salience character of wet friction clutch that there are some oil grooves in friction disk surface. These oil grooves can increase friction coefficient and emanate heat quantity. Confirming conformable friction disk’s surface oil groove configuration by experiment research is received. It confirmed that the appropriate surface oil groove configuration of friction disk should be double-arc groove.
