Vibration damper for crankshaft in internal combustion engine has flange component connected to crankshaft, flywheel mass rotatable in relation to flange component, and primary and secondary damping elements

摘要

The vibration damper (1) for a crankshaft (2) in an internal combustion engine has a flange component (3) connected to the crankshaft and flywheel mass (4) rotatable in relation to the flange component, at least one primary damping element (6) installed between the flange component and flywheel mass, and several secondary damping elements (7) for axial connection of the flange component to the flywheel mass, which to achieve a viscous damping between the flange component and flywheel mass are provided with intermediate chambers (12) to hold oil. An Independent claim is included for an internal combustion engine with a crankshaft incorporating the proposed vibration damper.
