Abstract
Official abstract text for this publication.
A soil compactor, including 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, wherein, in each case, at least one electromotive drive for producing an oscillating torque is assigned to each roller segment.
First claim
Opening claim text (preview).
The invention claimed is: 1. A soil compactor, comprising at least one compactor roller rotatable about an axis of rotation of the roller and having a plurality of roller segments following one another along the direction of the axis of rotation of the roller, each roller segment having exclusively assigned therewith at least one electromotive drive for producing an oscillating torque applied to this roller segment, wherein the at least one electromotive drive is configured as an external rotor motor with a stator and a rotor, which surrounds the stator and is coupled with the assigned roller segment, for a joint rotation about the axis of rotation of the roller, wherein a roller axle, which extends along the axis of rotation of the roller, is provided at a compactor frame in such a way that the roller axle does not rotate about the axis of rotation of the roller, the roller segments being supported so that they rotate about the roller axle, and wherein the stator of each external rotor motor is carried on the roller axle. 2. The soil compactor of claim 1 , wherein there are electric supply lines and/or supply lines for a cooling medium for each stator. 3. The soil compactor of claim 1 , wherein at least one and each roller segment is rotatably carried on the roller axle by means of at least one roller bearing. 4. The soil compactor of claim 1 , wherein, for at least one roller segment of the plurality of roller segments, at least one assigned electromotive drive is disposed in an interior space of the at least one roller segment, which is enclosed in a casing of the at least one roller segment. 5. The soil compactor of claim 1 , wherein there is, for at least at one roller segment of the plurality of roller segments, at least one assigned electromotive drive for producing a propulsion drive torque.
