ABSTRACT:
A torque fluctuation absorbing apparatus provided between a crankshaft of an engine and a driven-side input shaft includes a flywheel coupled to the crankshaft and a damper assembly disposed in a torque transmission path between the flywheel and the driven-side input shaft. The damper assembly includes a pair of drive plates, a driven plate and a spring damper. A torque limiter is disposed in a torque transmission path between the flywheel and the damper assembly. The torque limiter includes a pair of linings which generates relative rotational slip between the flywheel and the damper assembly when a torque larger than a predetermined amount is transmitted and are adapted to slip when receiving at least a predetermined amount of torque. The linings of the torque limiter are fixed to one of the drive plates and are interposed between a flywheel main body and a damper cover that forms a part of the torque limiter. The drive plates, the linings and the damper cover are centered with respect to the flywheel main body, and are assembled together to provide an assembly of the flywheel main body, the damper assembly and the torque limiter. After the engine is assembled with the driven-side input shaft, the assembly of the flywheel main body, the damper assembly and the torque limiter is fastened to the flywheel plate that is fixed to the crankshaft.
