A wheel assembly (200) includes a wheel (202) and a hub assembly (400). The hub assembly (400) includes a retainer housing (600), retaining member (700), biasing element (800), and restraining element (900). The retainer housing (600) includes a wheel mounting sleeve (602) and pin sleeve (604). The wheel mounting sleeve (602) includes an axle bore (606) configured to receive an axle (150) and configured to be inserted within a sleeve bore (210) of the wheel (202). The pin sleeve (604) includes a first end (607) fluidly communicating with the sleeve bore (210), a second end (608), and a conduit (610) therebetween. The retaining member (700), disposed within the conduit (610), is configured to operatively engage an axle groove (152) and includes a lip (704) wider than a first end shoulder (612) to prevent the retaining member (700) from exiting the first end (607). The biasing element (800), disposed within the conduit (610), is configured to bias the retaining member (700) towards the axle bore (606). The restraining element (900) is configured to prevent the retaining member (700) from exiting the second end (608). |
