Motor vehicle drive strand device, has balance mass for stimulating compensation vibration opposing vibration of drive shaft, and damping device with transmission unit, whose transmission ratio defines order of compensation vibration

摘要

The device has a vibration damping device (12a) for damping vibration of a drive shaft (11a). The damping device exhibits a balance mass (13a) that is arranged rotatable to the shaft. The mass stimulates compensation vibration that opposes the vibration of the shaft. The damping device exhibits a transmission unit (15a), whose transmission ratio defines an order of the compensation vibration. The transmission unit is designed as a planetary gear transmission (16a) with a planetary gear (17a). A coupling unit (14a) is arranged for eccentrically coupling the mass and the gear.
