The drag torque of a wet clutch is generated by the shear resistance of the transmission fluid in the gap between clutch plates during a disengagement period, thus reducing transmission efficiency. To lessen power loss in the transmission, drag torque should be reduced in the different aspects of the design. In general, oil groove patterns of a double sided friction plate do not necessarily match the oil groove pattern phase of each side due to manufacturing difficulty and productivity. However, a double-sided clutch plate with non-phased patterns rotates with a certain gap distance from the steel plate by randomly directing the transmission fluid to the outer radius through the oil groove patterns. If the outflow is well guided through the phased groove patterns on the double-sided clutch plate, then the drag torque is lessened. In this study, the drag torque of the double-sided clutch pad is investigated with the phase aspect of the clutch pad pattern on each side of the clutch pad. Phased and non-phased, double-sided clutch pads are produced according to the drag torque measurements under various operating conditions related to flow rates, temperatures, operating speeds, and groove patterns. |
