Abstract
A wheel of the roller type, i.e., whose general shape is constituted by two sides the contours of which are circles with respective centers. O,O′, the flanks being substantially parallel with respect to one another, substantially perpendicular to an axis OO′ and connected to one another by a substantially toric surface portion having an axis of rotation OO′. The wheel is particularly intended as a wheel for a roller skate. The wheel includes a generally annular tread with an axis of rotation OO′, one outer surface of which is adapted to come in contact with the ground, the tread being made of at least one first material; a generally annular hub having an axis of rotation OO′ including an interface zone ensuring the cohesion of the hub and of the tread, a substantially cylindrical central surface adapted to cooperate with means fixing the wheel on a rotational shaft having an axis of rotation OO′, and a hub body connecting the central surface to the interface zone, the hub being made of at least one second material, which material is different from the first; and an annular groove having an axis OO′ provided on each of the sides of the wheel…
