A plastic wheel assembly (122, 222) and wheel mounting sleeve (127, 227) used to releasably secure the wheel (122, 222) onto an axle (123, 223). The wheel mounting sleeve (127, 227) includes an axle stabilizing opening (100, 200) positioned in an end wall (158, 258) of the sleeve which receives an axle outer end or axle stub (199, 299) that supports the axle (123, 223) against lateral loading and stabilizes it to reduce wobble, chatter and vibration. The opening (100, 200) permits visual confirmation of proper section of the axle outer end (199, 299) in the opening (100, 200). A universal axle (223, 223a) is also provided which can be used to couple wheels (122, 222) having shaped axle bores (139, 239) to the axle using wheel mounting sleeves (127, 227), as well as being used to couple wheels (420), having straight or substantially cylindrical bores (439), to the axle using conventional fasteners (450, 461, 470).

Ensemble de roue en plastique (122, 222) et gaine de montage de roue (127, 227) utilisés pour fixer de façon amovible la roue (122, 222) à un essieu (123, 223). La gaine de montage de roue (127, 227) comporte une ouverture de stabilisation d'essieu (100, 200) positionnée dans une paroi d'extrémité (158, 258) de la gaine qui reçoit une extrémité externe d'essieu ou un embout d'essieu (199, 299) qui soutient l'essieu (123, 223) contre les charges latérales et le stabilise pour réduire le battement, le broutage et les vibrations. L'ouverture (100, 200) permet une confirmation visuelle d'une section correcte de l'extrémité externe de l'essieu (199, 299) dans l'ouverture (100, 200). Un essieu universel (223, 223a) est également prévu pour accoupler des roues (122, 222) possédant des alésages d'essieu profilés (139, 239) à l'essieu au moyen des gaines de montage de roue (127, 227), de même que pour accoupler des roues (420) ayant des alésages droits ou essentiellement cylindriques (439) à l'essieu au moyen d'attaches conventionnelles (450, 461, 470).
