Abstract
A tooth for a compactor vehicle that includes a base and a cap. The base comprises a body and a retention feature. The body defines an underside, configured to engage a wheel of the compactor vehicle, and an opposing cap-facing side. The cap comprises an outer surface and a retention feature. The outer surface defines a compaction surface. The retention features of the base and cap interlock with one another to secure the cap to the base. A cavity is defined in the underside of the base.
Claims19
A tooth for a compactor vehicle, the tooth comprising a base and a cap;
- wherein the base comprises:
- a body defining an underside, configured to engage a wheel of the compactor vehicle, and an opposing cap-facing side;
- and
- a first retention feature;
- wherein the cap comprises:
- an outer surface defining a compaction surface;
- and
- a second retention feature;
- wherein the first and second retention features interlock with one another to secure the cap to the base and prevent the cap from separating from the base;
- and
- wherein a cavity is defined in the underside of the base.
A method of manufacturing a tooth for a compactor vehicle, wherein the tooth comprises a base and a cap;
- wherein the base comprises:
- a body defining an underside, configured to engage a wheel of the compactor vehicle, and an opposing cap-facing side;
- and
- a first retention feature;
- wherein the cap comprises:
- an outer surface defining a compaction surface;
- and
- a second retention feature;
- wherein a cavity is defined in the underside of the base;
- the method comprising:
- casting the base using a first molten metal material;
- casting the cap onto at least the cap-facing side of the base using a second molten metal material;
- wherein the first and second retention features interlock with one another to secure the cap to the base whilst the second molten material is at least partly molten;
- and
- wherein the second molten metal material is substantially prevented from entering the cavity.
A base for a compactor vehicle tooth, the base comprising:
- a body defining an underside, configured to engage a wheel of a compactor vehicle, and an opposing cap-facing side, the body comprising a cavity defined in the underside;
- and
- an attachment portion which projects from the cap-facing side of the base and comprises a generally arcuate aperture;
- wherein the generally arcuate aperture extends through the attachment portion and is configured to interlock with a retention feature of a cap;
- and
- wherein the body further comprises one or more recesses which extend from the cap-facing side to the cavity and generally increase in cross-sectional area from the cap-facing side towards the cavity.
