Abstract
A compactor roller for a soil compactor comprises a roller shell (), rotatable about a roller axis of rotation (W) and surrounding a roller interior (), an oscillation/vibration assembly () arranged in the roller interior (), wherein the oscillation/vibration assembly () comprises a first oscillation/vibration unit () with at least one drivable first unbalanced mass (') for rotation about a first oscillation/vibration axis of rotation (D), and a second oscillation/vibration unit () with at least one drivable second unbalanced mass (′) for rotation about a second oscillation/vibration axis of rotation (D.) A center of mass of a second unbalanced mass part of the at least one first unbalanced mass (′) and/or a center of mass of a second unbalanced mass part of the at least one second unbalanced mass (′) moves, during the movement of the respective second unbalanced mass part () between two end positions about the assigned oscillation/vibration axis of rotation (D, D) in an angle of less than 180°.
