Abstract:

The mathematical models of drag torque and shift synchronization process of multi-plate wet clutch were established. Simulation was carried out in Matlab/Simulink. Simulation results were compared with experiment results. It is demonstrated that the models are correct and accurate. The influences of friction pair gap in multi-plate wet clutch, cooling oil flow rate and properties of cooling oil under different temperature etc. on the drag torque, shift synchronization time and energy were analyzed. This study may provide a reference for theoretical study and structural design of the multi-plate wet clutch, and for the transmission system matching.

Key words: vehicle engineering, multi-plate wet clutch, drag torque, synchronization shift, synchronization energy
