Description
Summary:A Finite Element Analysis technique was used to predict the clutch lining load distribution in automatic transmissions. This technique is explained and demonstrated on several clutch designs. The analysis shows the importance of rigid backing plates and optimum piston apply points. The benefit of tapered apply plates is also discussed. The importance of having a uniform clutch lining load distribution is described as it relates to clutch torque and energy capacity.
