A wheel (1) with an integrally formed wheel frame including a central hub (2) rotatable about a main axis, a plurality of first supports in a first plane transverse to the main axis and radially spaced from the central hub (2) to form a first discontinuous rim with a first series of rollers (4) regularly spaced around the first rim, a plurality of second supports radially spaced from the hub to form a second discontinuous rim with a second series of rollers (5) regularly spaced around the s econd rim, each rollers having a main body wherein the lateral central cross-sectional diameter is greater then the diameter of the end portions, each roller being rotatable about an axis transverse to the main axis and when viewed from a side elevation, there being substantial overlap of each of the first series of rollers (4) with each diagonally adjacent roller of the second series of rollers (5).

La présente invention concerne une roue (1) comprenant une armature de roue monobloc présentant un moyeu central (2) pouvant tourner autour d'un axe principal, une pluralité de premiers supports disposés dans un premier plan transversal à l'axe principal et espacés radialement du moyeu central (2) pour former une première jante discontinue avec une première série de rouleaux (4) disposés à intervalles réguliers autour de la première jante, une pluralité de seconds supports espacés radialement du moyeu pour former une seconde jante discontinue avec une seconde série de rouleaux (5) disposés à intervalles réguliers autour de la seconde jante. Selon l'invention, chacun des rouleaux comprend un corps principal, le diamètre central latéral de section transversale étant supérieur au diamètre des parties d'extrémité, chaque rouleau peut tourner autour d'un axe transversal à l'axe principal, et, en vue de côté, il y a une recouvrement suffisant de chacun des rouleaux (4) de la première série avec chaque rouleau diagonalement adjacent de la seconde série de rouleaux (5).
