Abstract
A pendulum assembly comprises a cold forged steel pendulum or cold formed steel pendulum attached to a cold forged steel carrier or cold formed steel carrier. The carrier is attached to the crankshaft. The pendulum assembly includes a first outer steel plate, a second outer steel plate, and an intermediate steel plate. The stamped plates are formed from flat sheet steel to provide the pendulum shape and features. The outer steel plates are attached to the intermediate steel plate by any of a variety of methods. The pendulum carrier of the disclosed inventive concept is comprised of one or more steel plates that are also cold forged or cold formed from steel to provide the pendulum carrier shape and features. Alternatively, the pendulum carrier may include two cold forged or cold formed portions attached together or three cold forged or cold formed portions attached together.
