Abstract
In order to study the mechanism and the change law of the belt discharge torque of the friction plates under the no-load condition of the wet clutchs at high linear speed, a belt was established based on the hydrodynamics model considering the influences of the surface tension of the lubricating oil film and the oil-gas two-phase flow at high linear speed. The mathematical model of the drag torque was used to establish the volume fraction of air and oil two phases flow simulation for the oil film with an exhaust gap to analyze and verify the change of the oil film. The analysis of the model shows that the oil-gas two-phase flow of the friction plate produces part of drag torque at high linear speed, which is the main reason for the recovery of drag torque. Drag torque tests was did in highspeed belt-row test system for friction components. The influences of direction, lubricating oil temperature, flow rate, belt-row gap, and friction plate size on drag torque were analyzed.
