Abstract
A tilger for a rotating body includes an annular body movably coupled to a rotatable portion of the rotating body. The tilger includes a spring interposed between the first annular body and the rotatable portion. Rotation of the rotatable portion relative to the annular body is to compress and decompress the spring. The tilger includes a ring positioned on an outer surface of the annular body and configured to expand as a rotational speed of the ring increases to decrease a total inertia of the annular body and the ring applied to the spring.
Claims22
A tilger for a rotating body, comprising:
- an annular body movably coupled to a rotatable portion of the rotating body;
- a spring interposed between the first annular body and the rotatable portion, rotation of the rotatable portion relative to the annular body to compress and decompress the spring;
- and
- a ring positioned on an outer surface of the annular body and configured to expand as a rotational speed of the ring increases to decrease a total inertia of the annular body and the ring applied to the spring.

(canceled)
A vehicle torque converter, comprising:
- a cover to receive an engine torque;
- an output portion to receive the engine torque from the cover and provide the engine torque to a vehicle transmission system;
- and
- a damper system operatively interposed between the cover and the output portion to dampen relative rotational movement between the cover and the output portion when a clutch of the vehicle torque converter is in an engaged state, the damper system including a rotatable portion and one or more rings supported by the rotatable portion that at least partially define a natural frequency of the damper system, each of the one or more rings configured to change between contracted and expanded states in response to rotation of the rotatable portion to change the natural frequency.
