With the purpose of improving the control effect of the wet clutch oiling process,on the basis of the numerical model of the clutch oiling process,an oiling model based on MATLAB/Simulink software was established for simulation analysis,and a test bed was built for verification.The relationship between the oil flow rate and the boost characteristics of the clutch was obtained.The influence of oil temperature,return spring stiffness and pre-compression as well as the friction sub gap on clutch pre-filling was further investigated.Finally,the oiling requirements and pre-filling control method for different clutch stages was gotten.It provides a theoretical basis for parameters matching and optimization of the clutch oiling process.
