Abstract
A soil compactor includes at least one compactor roller, which is free to rotate about an axis of rotation of the roller, with a plurality of roller segments, which follow one another along the direction of the axis of rotation of the roller. In each case, at least one electromotive drive for producing an oscillating torque is assigned to each roller segment.
Claims9
A soil compactor comprising at least one compactor roller rotatable about an axis of rotation of the roller and a plurality of roller segments following one another along the direction of the axis of rotation of the roller,
- each roller segment having a casing surrounding an interior space of the respective roller segment,
- each roller segment having exclusively assigned therewith an electromotive drive arranged in the interior space surrounded by the casing of the respective roller segment for producing a propulsion drive torque, each electromotive drive for producing a propulsion drive torque being arranged for additionally producing an oscillating torque applied to the roller segment associated therewith,
- a roller axle extending along the axis of rotation of the roller being fixed at both axial ends thereof at a compactor frame such that the roller axle does not rotate about the axis of rotation of the roller, each roller segment being rotatably carried on the roller axle by at least one roller bearing so as to rotate about the roller axle,
- the interior space of each roller segment being closed off or limited in the axial direction by at least one side support, the at least one side support being rotatably carried by at least one roller bearing of the at least one roller bearing on the roller axle.
