Abstract: front page image
(EN)The invention concerns a soil compaction roller (10) and a soil compaction machine of which the roller (10) forms part. The roller (10) comprises a multi-sided, out-of-round, peripheral compacting surface (16) which can roll over a soil surface which is to be compacted. The compacting surface (16) is defined by a series of angularly spaced salient points (20) and a corresponding series of compacting faces (22). Each compacting face (22) is outwardly convex in shape and extends continuously between two adjacent salient points (20). When the roller (10) is operative with the compacting surface (16) rolling over the soil surface, the roller rises up on each salient point (20) in turn, storing potential energy, and thereafter rolls downwardly onto the succeeding compacting face (22) to transmit the stored potential energy to the soil surface to compact it. The instantaneous centre of rotation of the compacting surface (16), where it contacts the soil surface during rolling, moves continuously about substantially the full extent of the compacting surface.
(FR)L'invention concerne un rouleau (10) de compactage du sol et une machine de compactage du sol dont le rouleau fait partie. Le rouleau (10) comporte une surface (16) de compactage périphérique, polygonale et aplatie qui pouvant rouler sur la surface du sol à compacter. La surface (16) de compactage est définie par une série d'angles saillants (20) espacés et une série correspondante de faces (22) de compactage. Chaque face de (22) compactage est convexe vers l'extérieur et s'étend de façon continue entre deux angles saillants (20) adjacents. Lorsque le rouleau (10) opère de concert avec la surface (16) de compactage roulant sur la surface du sol, le rouleau s'élève successivement sur chaque angle saillant (20), stockant ainsi de l'énergie potentielle, puis roule vers le bas sur chaque face (22) de compactage successivement pour transmettre l'énergie potentielle stockée à la surface du sol et ainsi la compacter. Le centre de rotation instantané de la surface (16) de compactage, ou le point où elle entre en contact avec la surface du sol pendant la rotation, se déplace continuellement sur sensiblement toute l'étendue de la surface de compactage.
