Latest Patents
One of his latest patents is for a "Tuned damper for a torque converter clutch." This invention involves a rotary damper mounted to a clutch pressure plate within a torque converter clutch of an automatic transmission. The rotary damper is specifically tuned to minimize the magnitude of a natural frequency of rotary vibration in a driveline system, which is induced by the engine firing frequency. Another significant patent is for a "Clutch damper with friction lag." This clutch damper assembly features a friction lag device that is energized in only one direction of torque variance. During torque transients, a torque increase in the forward direction is resisted by the springs in the damper, while a torque decrease is absorbed by the friction lag device. The friction lag device consists of wedge-shaped pads that are disposed in pockets on one portion of the clutch damper, allowing for effective engagement and disengagement during operation.
