Vibration damper i.e. dynamic vibration damper, for use in drive train of motor vehicle e.g. lorry, has flywheel rotationally connected with shaft of drive train by planetary gear that causes speed reduction between shaft and flywheel

摘要

The damper (1) has two pendulum masses (4) fastened to a flywheel (2) in such a manner that the masses are moved along predetermined movement paths relative to the flywheel. The flywheel is rotationally connected with a drive train shaft (3) i.e. crankshaft, of a drive train by a planetary gear (5) that is integrated into the flywheel. The gear causes a speed reduction between the drive train shaft and the flywheel and has an internal gear that is connected with the drive train shaft in a torque-proof manner.
