Torsion oscillation dampener for automotive crankshaft minimises the size of heat transmission paths to heat-sensitive zones

摘要

A torsion oscillation dampener has a concentric dampener on the output side which interfaces with a clutch friction plate. The dampener bears a layer of heat insulation material. The output side of the dampening element has a number of circumferential recesses (100) whose width is several times that of cross-pieces (102) in the same direction.
