Abstract
The invention concerns a device for ground compacting, having at least one vibrating roller whose casing surface is composed of a plurality of segments in the peripheral direction, at least some of which have midpoints which describe an arc having a radius of curvature that deviates from the mean radius of the roller. In order to smooth the jolting movement resulting from the shape of the rollers in devices of this type, it is proposed to construct the tire casing of the roller from several sections lying adjacent to one another in the axial direction, said sections having segments abutting one another in the peripheral direction, whereby the abutting edges are displaced vis-à-vis one another in the peripheral direction.
Claims15
A ground compacting device comprising at least one vibrating roller with a central shaft axis, the at least one roller having a casing surface comprising a plurality of sections lying adjacent one another in an axial direction of the at least one roller, at least some of the sections having a plurality of segments lying end to end in a peripheral direction of the at least one roller and each segment having a dimension extending in the axial direction parallel to said shaft axis, wherein there are substantially no gaps in the axial direction between segments of adjacent sections, the segments of the at least some sections abutting each other in the peripheral direction of the at least one roller at edges which are always displaced in a peripheral direction from abutting edges of an adjacent section, each segment having a major surface and having midpoints which are disposed on a radius which is less than a mean radius of the at least one roller, such that ground compaction is effected by normal forces transmitted by the major surfaces when they contact the ground,
- wherein at least two sections of the plurality of sections each have a plate, so that the individual sections provide a peripheral continuous roller surface and the at least one roller is at least partially supported and stabilized by the plates and the sections.
