Patent ID: 6976920

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 generate 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 of the damper assembly, and the torque limiter includes a pair of damper covers between which the linings are interposed via a coned disc spring, and the drive plates and damper covers are centered with respect to each other, whereby the damper assembly and the torque limiter are assembled to a damper-torque limiter assembly, and the damper-torque limiter assembly is fixed to the flywheel via the damper covers, further comprising a bush that is disposed in a radial clearance between one of the drive plates and a damper cover of the pair of damper covers that forms a part of the torque limiter, so as to support the drive plate and the damper cover.
