Abstract
A torque fluctuation absorbing apparatus includes a flywheel coupled to an engine crankshaft, a damper assembly disposed between the flywheel and the driven-side input shaft and including a pair of drive plates, a driven plate and spring dampers, and a torque limiter disposed between the flywheel and the damper assembly and including a pair of linings that are adapted to slip when receiving at least a predetermined amount of torque. The apparatus is provided with a structure for reducing misalignment of the torque limiter during assembling thereof. For example, the torque limiter further includes a lining support plate to which the linings are fixed, and the linings are interposed between the drive plates. In fabricating the apparatus, the drive plates and the linings are centered with each other and assembled into a damper-torque limiter assembly, while the lining support plate is centered with respect to the flywheel, such that the damper-torque limiter assembly is fixed at the lining support plate to the flywheel.
