Abstract:
Blade and spring damper apparatus for use with vehicle torque converters are disclosed. A disclosed vehicle torque converter includes a housing, a hub, a clutch including a piston in the housing, and a damper assembly operatively interposed between the clutch and the hub. The damper assembly includes a blade damper having a blade and a roller engaging the blade. Movement of the roller relative to the blade bends and unbends the blade. The damper assembly also includes a spring damper connected to the blade damper. The spring damper includes a first spring damper portion, a second spring damper portion, and a spring between the first and second spring damper portions. Movement of the first spring damper portion relative to the second spring damper portion compresses and decompresses the spring. The blade damper and the spring damper, together, are configured to dampen a torsional vibration received by the housing when the clutch is engaged.
