Research on Friction Disk Surface Oil Groove Configuration and Temperature Raise in Wet Friction Clutch

Friction disk temperature distribution and invalidation reasons of wet friction clutch used in duty truck were studied by contact temperature calculation model and thermal analysis theory.Simple and practical formula of friction disk surface temperature was obtained by confirmation of experiment research.Normal oil groove configurations on driven friction disk surface were introduced and effects of different oil groove configurations on transfer torque, friction disk surface temperature and drag torque were analyzed.Test results show that double arc oil groove in driven friction disk surface is optimal groove used in duty truck by experiment research because of its good synthesis characteristics,fitful friction coefficient,little influence to drag torque and it is easy to manufacture.
