However, as will be seen, in these patents, both of these wheel mounting hub assemblies are relatively complex and employ multiple pieces of the hub in order to secure the wheel on the axle
Consequently, the size of the wheels and axles is reduced and the use of these components becomes more difficult
[0013] In US5277480 and 5902018 a separate retainer arrangement is used with the bushing, but the outer end of the shaft is substantially unsupported, hubcaps must be used for safety and / or aesthetic reasons

Embodiment Construction
[0037] The wheel mounting hub and wheel set of the present invention can be used in several wheeled equipment. A typical but not limited application is, in figure 1 This structure is employed in a wheeled refuse vehicle or container of the general form shown in . Thus, the garbage truck 21 includes a pair of wheels 22 mounted on axles 23 at the lower portion of the garbage truck body 29 . Optionally a hinged cover 24 is provided, and the handle 26 can be used to tilt or tip the refuse vehicle around the wheels, so that the refuse vehicle can be pushed for conveyance, for example, between a loading position and a waste disposal site pick-up position.
[0038]The wheel 22 is secured to the shaft 23 by a wheel mounting bushing generally indicated at 27 . In the illustrated refuse vehicle, the body of the refuse vehicle includes a wheel well or recessed area 28 that receives the wheels 22, which serve to protect the wheels and in part as an aesthetic feature. However, many garb...

Abstract
A plastic wheel (122, 222) and wheel mounting sleeve (127, 227, 327, 427) used to releasably secure the wheel (122, 222) onto an axle (123, 223). The wheel mounting sleeve (127, 227, 327, 427) preferably includes a resilient, radially displaceable, axially extending, cantilevered finger (146, 246, 346, 446) which includes an axle-engaging lug (155, 255, 355, 455), while a wheel- engaging shoulderis provided on the sleeve by an annular rib (201, 301). The sleeve shoulders latch the sleeve (127, 227, 327, 427) to the axle (123, 223) and the wheel (122, 222) to the sleeve. The sleeve (127, 227,327, 427) includes an axle stabilizing recess (198, 298, 398, 498) positioned in an end wall (158, 258, 358, 458), which receives an axle stub (199, 299) that supports the axle (123, 223) against lateral loading and stabilizes it to reduce wobble, chatter and vibration.
Description
[0001] related application [0002] This is based on a continuation-in-part of co-pending patent application number 09 / 687669, filed December 12, 2000 and entitled "Plastic Wheelset and Improved Mounting Bushings Therefor," which co-pending application It is also a continuation-in-part based on application number 09 / 507595, dated February 18, 2000 and entitled "Plastic Wheel Set and Mounting Hubs Thereof". technical field [0003] The present invention relates generally to wheelsets and methods of mounting and detaching them on and off axles, and more particularly to a plastic wheelset for use on garbage trucks, wheel coolers, wagons, wheeled toys, barbecue grills, etc. type. Background technique [0004] In recent years, there has been a significant increase in the use of plastic wheels on various products. One area in which such plastic wheels have found widespread use is on the wheeled waste (or garbage) cart (or bin) types that private homeowners typically employ to di...
