Abstract: A pendulum absorber system attenuates torsional vibrations within a drive train of a vehicle. The system can be incorporated between an engine and an automatic transmission, for example, within a flex plate assembly attached to an engine's crankshaft, within a pump housing cover of a torque converter, or as a stand-alone unit between a flex plate assembly and a torque converter. The system includes at least one pendulum weight that dynamically moves along a predetermined path in response to variations in rotational velocities of a housing of the system and that is tuned to attenuate excitation of torsional vibrations within the drive train. A limiter assembly, which can include multiple limiters, is provided within the system for stopping movement of the weight when it reaches endpoints of the predetermined path, by mechanically impeding further movement at both of a first and second end of the weight.
