Abstract
A crankshaft assembly for an internal combustion engine can include a crankshaft having a lobe with a pendulum absorber coupled thereto. The pendulum absorber can include a carrier, a pendulum, a pin and a centrifugal switch assembly. The carrier can be coupled to a body of the lobe and can have an opening therein. The pendulum can have an opening therein and the pin can extend through the pendulum opening and the carrier opening to pivotably couple the pendulum to the carrier. The switch assembly can be slidably positioned in a bore of the body and can have a lock member configured to selectively engage the pendulum based on a centrifugal force being below a predetermined threshold to lock movement of the pendulum relative to the carrier.
