Characterization of Wet Clutch Hydraulic System for High Power Tractors
The wet clutch of high-power tractor is characterized by complexity,high order and strong nonlinearity,which is the key component to complete the shift action of power shift transmission(PST).Firstly,the composition and working principle of the wet clutch hydraulic system of high-power power shift tractor were analyzed.Then,a wet clutch hydraulic system test bench based on dSPCE system was built.The wet clutch hydraulic system characteristic test was carried out,and the steady-state and dynamic characteristics of the proportional pressure reducing valve and wet clutch were analyzed.Finally,the piston displacement stroke and basic motion characteristics of the wet clutch were obtained by modifying the clutch test bench and collecting the piston displacement and oil pressure of the clutch.The research results can provide a modeling basis for clutch pressure control and shift quality control research.
