Patent ID: 7169054

Claim:
A torque fluctuation absorbing apparatus provided between a crankshaft of an engine and a driven-side input shaft, comprising: a flywheel coupled to the crankshaft; a damper assembly disposed in a torque transmission path between the flywheel and the driven-side input shaft, the damper assembly including a pair of drive plates, a driven plate and at least one spring damper; and a torque limiter disposed in a torque transmission path between the flywheel and the damper assembly, the torque limiter including 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, wherein the linings of the torque limiter are fixed to one of the drive plates, and the linings are interposed between the flywheel and a damper cover that forms a part of the torque limiter, while the flywheel includes a flywheel main body and a flywheel plate that are fastened to each other, 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 drive-side input shaft, the assembly of the flywheel main body, the damper assembly and the torque limiter is fastened by bolting to the flywheel plate that is fixed to the crankshaft.
