A trolley wheel assembly (210) includes a wheel portion (212) rotatably positioned around a hub portion (214) and at least one sliding member (217) positioned between the wheel portion and the hub portion. The sliding member defines a mating surface for mating with a generally correspondingly formed mating surface of the wheel portion and/or the hub portion. The mating surface of the sliding member defines a radial projection (217a) at least substantially circumferentially around the sliding member. The radial projection may slidably mate with the generally correspondingly formed mating surface of the wheel portion and/or the hub portion to facilitate rotation of the wheel portion about the hub portion. The wheel assembly may include one or more inserts (216a, 216b) that define the correspondingly formed mating surface and that are positioned between the sliding member and the wheel or hub portion to facilitate manufacturing and assembly of the wheel assembly.
Un ensemble de roue pour chariot (210) comprend une partie roue (212) disposée rotative autour d'une partie moyeu (214) et au moins un organe coulissant (217) disposé entre la partie roue et la partie moyeu. L'organe coulissant délimite une surface de contact destinée à entrer en contact avec une surface de contact de forme généralement correspondante de la partie roue et/ou de la partie moyeu. La surface de contact de l'organe coulissant définit une saillie radiale (217a) disposée de manière sensiblement circulaire autour de l'organe coulissant. La saillie radiale peut rentrer coulissante dans la surface de forme généralement correspondante de la partie roue et/ou de la partie moyeu de manière à faciliter la rotation de la partie roue autour de la partie moyeu. L'ensemble roue peut comprendre un ou plusieurs inserts (216a, 216b) qui définissent la surface correspondante, et qui sont disposés entre l'organe coulissant et la partie roue ou la partie moyeu de manière à faciliter la fabrication et l'assemblage de la roue.
