25

Compaction machines are used to compact land?ll sites, garbage dumps and other such locations. These machines typically include a self-propelled vehicle having four large wheels made of steel. Each wheel has a hub mounted to one

end of an axle and a rim disposed around and radially out from the hub. The rim typically includes an outer wrapper on which a plurality of cleats are usually mounted. One problem encountered by such machines is the accumulation of waste behind the compaction wheel. Waste materials such as steel

Depending on how close they are to the inner edge of the

cable, wire, rope and the like have a particularly detrimental effect. Such refuse tends to wrap around the axles of the

compaction machine and become trapped between the wheel and its axle, increasing the corresponding frictional forces therebetween. Increasing the friction between the wheel and

tem comprises a cleat-free area formed circumferentially around the rim on its face. The cleat-free area extends width wise from the inner circumferential edge of the rim and across the rim toward the outer circumferential edge of the rim at least about the width of one of the cleats. Such a cleat-free area can be obtained by removing the inner circumferential row of cleats on the compactor wheel.

By removing the inner circumferential row of cleats or moving the inner row of cleats away from the inner edge of the wheel wrapper or rim, the refuse is less likely to be directed toward the axle area and end up wrapped around the axle.

20

the hub 11. The rim 18 includes a Wrapper 19 With an outer face or surface 21 on Which a plurality of cleats 28 are

mounted, such as by Welding or any other suitable technique. The Wheel 10 also includes an axle guard system such as, for example, a circumferential barrier 16 Which extends radially

refuse toWard the Wheel’s axle 12. By removing the inner

tively be obtained by extending the inner edge 20 of the Wheel

The barrier 16 extends radially out from the rim 18 to a 30

about 1 inch to about 8 inches. For a Wheel 10 With cleats 28

each having a height of about 6 to 7 inches, satisfactory results have been obtained using a barrier 16 having a height of about

35

4 inches and a thickness of about 2 inches.

The barrier 16 shoWn in FIGS. 1 and 2 comprises a single

ring-shaped Wall 22 mounted circumferentially around the Wrapper 19 of the rim 18. It can be desirable for the ring 22 to be supported or reinforced by some kind of buttressing struc

40

ture 24 to, for example, help prevent the ring 22 from being bent or knocked off during the operation of the compaction machine 14. The need for such a buttressing structure 24

reduces, for example, as the height of the barrier 16 decreases.

45

The need for a buttress 24 also reduces, for example, as the thickness of the barrier 1 6 increases. The buttressing structure 24 can be a ?aring or broadening 23 of the thickness of the

ring 22 Where the ring 22 is mounted to the rim 18 (see FIG. 3). The buttressing structure 24 can also be structure separate

The buttressing structure 24 can also be any other continu ous structure, such as a ring-shaped plate, that provides the barrier 16 With the desired degree of support. Instead of a continuous structure, the buttress 24 can comprise a series of

machine 14. In an effort to effectively move the inner circumferential roW 36 of the cleats 28 aWay from the inner edge 20 of the Wheel Wrapper 19, it may be desirable to extend the outer edge 20 of the Wrapper 19 and shift all of the circumferential roWs of the cleats 28, including the innermost roW 36, aWay from the inner edge 20 of the Wheel Wrapper 19. It may also be desirable to extend both the inner circumferential edge 20 and the outer circumferential edge 39 of the Wheel Wrapper 19 to

distance aWay from the axle 12 (i.e., the inner edge 20 of the Wrapper 19) Without having to remove the inner roW 3 6 of the 50

cleats 28. Especially for narroWer compactor Wheels 10 (i.e., those Wheels that have a Width, from edge 20 to edge 39, of about 35 inches or smaller), it is best not to remove the inner circumferential roW 36 of the cleats 28, if possible. The nar

roWer compactor Wheels 10 typically have only three circum ferential roWs of the cleats 28. The Wider compactor Wheels 55

10 (i.e., those Wheels having an edge to edge Width of greater than about 35 inches) typically have four to ?ve circumfer

60

ential roWs of the cleats 28 and are less affected by the loss of the inner roW 36 of the cleats 28. When a ring-shaped barrier 22 is used With a Wider com pactor Wheel 10, it can be desirable to remove the inner roW of

65

Referring to FIGS. 7A-7C, the ring-shaped barrier 22 can also be a V-notched ring-shaped barrier 38, With a plurality of V- shaped notches spaced along the outer circumference of the ring 38, a rectangle-notched ring-shaped barrier 40, With a

Wrapper 19 toWard the compaction machine 14. It may also be possible to obtain the desired results by doing a combination of moving the inner circumferential roW 36 of the cleats 28 and extending the inner edge 20 of the Wheel Wrapper 19. The extent to Which the inner edge 20 of the Wheel Wrapper 19 is extended is dependant on the alloWable clearance permitted betWeen the compactor Wheel 10 and the compaction
