ABSTRACT:
A wheel assembly especially suitable for use on large heavy refuse carts. The wheel assembly includes an axis which has been heat treated and plated to provide a central core, an outer skin on the central core of substantially increased strength and hardness, and a chromium plating on the outer skin, and the associated hub of the wheel has been heat treated to provide an annular interior skin in journalling association with the axle having an increased hardness and strength as compared to the main body of the hub. The chrome plating on the axle has a hardness in excess of the hardness of the interior hardened skin of the wheel hub. The wheel assembly is mounted between spaced parallel mounting plates on the associated refuse cart with the ends of the axle passing through apertures in the lower ends of the mounting plates and with the assembly held in place between the mounting plates by a bolt carrying a washer and threadably engaging a blind bore in one end of the axle so as to position an end plate on the other end of the axle against the outboard face of the outboard mounting plate. A pair of seals are provided at each end of the hub of the wheel and an annular grease groove is provided in the hub inboard of each pair of seals.
