Abstract
A centrifugal pendulum absorber, including: a first pendulum mass; a second pendulum mass; a center plate axially located between the first pendulum mass and the second pendulum mass, connected to the first pendulum mass and the second pendulum mass, and arranged to receive rotational torque; a first resilient bumper axially located between the first pendulum mass and the second pendulum mass, and connected to the first pendulum mass and the second pendulum mass; and a first radial travel stop connected to the first pendulum mass or to the second pendulum mass, located radially outward of the first resilient bumper, radially aligned with at least a portion of the first resilient bumper, and free of contact with the first resilient bumper when the centrifugal pendulum absorber is at rest.
