Abstract
A pendulum crankshaft assembly for an internal combustion engine includes a pendulum carrier, a pendulum and rolling pins. The carrier and the pendulum have kidney-shaped rolling pin tracks. The rolling pin tracks are kidney-shaped and thus are defined by opposed curved side walls and opposed end walls. The pendulum carrier has an ear extending therefrom to which the pendulum is attached. The pendulum comprises a first half and a second half, each half being positioned on the sides of the ear. At any given time in operation, the gap between the rolling pin and the opposed walls of the rolling pin tracks is never greater than 0.5 mm. The pendulum carrier is attached to a cheek of the crankshaft by a pair of opposed fasteners.
