Abstract
A pendulum absorber fixed to the crankshaft of an engine comprises a pendulum and a pendulum carrier attached to the pendulum carrier attachment boss of the crankshaft. Each pendulum carrier has a pair of parallel ears extending therefrom. The carrier is tightly attached to the attachment boss such that the attachment boss is captured between the ears of the carrier. Attachment of the pendulum carrier to the sides of the attachment boss allows for feasibility in production, unlike known arrangements which require attachment of the pendulum carrier to the top of the crankshaft web. The fastener may be a pair of pressed-in pins, a single shrink-fit pin, shoulder bolts, Z-Form™ fastener assemblies, or rivets. Regardless of the type of fastener used, the side attachment arrangement of the disclosed inventive concept is sufficient to carry the load in sheer and prevent the pendulum assemblies from moving relative to the crankshaft.
