The invention relates to a drive assembly (100) with a drive shaft (10). A predetermined number of masses (30) is arranged along the drive shaft (10) and is movable radially in relation thereto, means (14) being provided which move the masses (30) in such a manner that they are radially spaced from the drive shaft (10) in a predetermined angle segment of the rotation of the drive shaft (10) in such a manner that they exert a torque on the drive shaft (10) as a result of gravity.
