US 10,295,014 B2 · Robust pendulum crank bumper

Abstract

A bumper clip having rubber or elastomeric bumpers for use with a pendulum assembly for attachment to the crankshaft of an internal combustion engine is disclosed. The bumper clip is has particular application for use with pendulum carriers that are formed from stamped steel. By using the stamped steel carrier, more room is created to provide a more robust bumper. The pendulum carrier bumper clip can be either two separate, L-shaped clips or a single U-shaped clip. If the pendulum carrier bumper clip includes two separate clips, each clip includes a bumper surface to which the bumper is attached and an attachment leg for attachment of the clip to the pendulum carrier and to the crankshaft by a fastener such as a bolt. The bumper surface has a channel through which the pendulum carrier passes, thus dividing the bumper surface into two surfaces. A bumper is attached to each surface.
