CRANKSHAFT ASSEMBLY COMPRISING A TORSIONAL VIBRATION DAMPER

WIPO Patent Application WO/2017/158131

A3

The invention relates to a crankshaft assembly (1) which is designed for a reciprocating-piston machine of an internal combustion engine, consisting of a crankshaft (2), a torsional vibration damper (3) for damping resonance torsional vibrations of the elastic torsion modes of the crankshaft, and an output (5), wherein the torsional vibration damper (3) consists of a primary mass inertia (31) and a secondary mass inertia (32), the primary mass inertia (31) being rigidly connected to a crankshaft (2) and the secondary mass inertia (32) being coupled as a seismic mass with a viscous liquid to the primary mass inertia (31). In addition to the function of reducing the resonance torsional vibrations of the crankshaft (2), the torsional vibration damper (3) is configured to also assume the function of a flywheel for reducing rotational non-uniformity, wherein the torsional vibration damper (3) is attached to an output end (5) of the crankshaft (2), and wherein the torsional vibration damper forms a centrifugal mass which is divided into a primary mass inertia and a secondary mass inertia, and wherein three functions - namely a clutch functional section, a flywheel and a torsional vibration damper - are integrated into the torsional vibration damper.
