Abstract
A damper assembly for cushioning the application of a torque delivery clutch in a torque converter transmission wherein the converter provides a complementary hydrokinetic torque delivery path, the damper assembly including a pair of cushioning springs acting in parallel and a third spring arranged in series relationship with respect to the paired cushioning springs, the spring rates being chosen to provide dampening forces that vary nonlinearly with the magnitude of the torque delivered through the damper.
