Abstract
In this paper, the theory of friction coefficient and thermal loads in slip state of a new hydro-viscous clutch has been studied and the influencing factors are determined. Furthermore, the friction characteristics test is designed. The test results show the variation tendency of friction coefficient when the hydro-viscous clutch operates at the difference temperature, difference normal pressure and difference rotating speed. The formula of different rotating speed on the impact of the coefficient of friction is fitted. The thermal load theory calculation reflects the temperature rising trend under different thermal loads of hydro-viscous clutch. Comparing the theoretical calculation and experimental results and analyzing the heat dissipation way of hydro-viscous clutch, it shows that the equation to calculating the thermal load that described the frictional state of frictional disk of hydro-viscous needs to be developed.
