Abstract
A compactor roller for a soil compactor comprises an oscillation mass assembly (34) including at least one oscillation shaft (36) rotatable about an oscillation-shaft axis of rotation eccentric to a compactor-roller axis of rotation, which oscillation mass assembly (34) includes at least one oscillation unbalance mass (66, 68), and a vibration mass assembly (84) including a vibration shaft (86) rotatable about a vibration shaft axis of rotation (Dv), which vibration mass assembly (84) includes at least one vibration unbalance mass (96), wherein at least one oscillation shaft (36, 38) and the vibration shaft (86) are carried in the compactor roller (10) such that they can be driven to rotate.
Claims21
A compactor roller for a soil compactor, comprising:
- an oscillation mass assembly including at least one oscillation shaft which is rotatable about an oscillation-shaft axis of rotation which is eccentric to a compactor-roller axis of rotation, and including at least one oscillation unbalance mass and a vibration mass assembly including a vibration shaft rotatable about a vibration-shaft axis of rotation, which vibration mass assembly includes at least one vibration unbalance mass
- wherein at least one oscillation shaft and the vibration shaft are carried in the compactor roller such that they can be driven to rotate, and
- wherein a shaft drive is provided for driving at least one oscillation shaft to rotate about its oscillation-shaft axis of rotation, wherein the shaft drive comprises a drive motor and a transmission drive assembly, wherein a rotational speed translation ratio of the transmission drive assembly varies depending on a rotational speed of the compactor roller about the compactor-roller axis of rotation.
