Abstract
A non-pneumatic tire assembly includes a non-pneumatic tire. The non-pneumatic tire includes an inner circumferential ring and an outer circumferential ring defining an annular space and a cylindrical space inside the inner circumferential ring. A plurality of partitions connect the circumferential rings within the annular space. A ground-contacting tread is located on the outer circumferential ring. A rim, including a plurality of pieces, is located within the cylindrical space. The non-pneumatic tire assembly further includes a hub that is removably connected to the rim.
Claims16
A non-pneumatic tire assembly, said non-pneumatic tire assembly comprising:
- a non-pneumatic tire, said non-pneumatic tire comprising:
- an inner circumferential ring and an outer circumferential ring defining an annular space between said circumferential rings and a cylindrical space inside said inner circumferential ring;
- a plurality of partitions within said annular space, wherein said partitions connect said circumferential rings;
- a ground-contacting tread located on said outer circumferential ring;
- a rim, said rim comprises a pair of rim halves, and said rim is located within said cylindrical space;
- and
- a hub, said hub is removably connected to said rim;
- wherein the rim halves are configured to be joined together and aligned to define a circumferential surface having a plurality of cavities about the circumferential surface;
- and
- wherein the inner circumferential ring defines a plurality of groups of axial ridges disposed about the inner circumferential ring, wherein each group of axial ridges is positioned and spaced to fit within a corresponding cavity within the circumferential surface defined by the rim halves when the rim halves are joined together.
A non-pneumatic tire, said non-pneumatic tire comprising:
- an inner circumferential ring and an outer circumferential ring defining an annular space between said circumferential rings and a cylindrical space inside said inner circumferential ring;
- a plurality of partitions within said annular space, wherein said partitions connect said circumferential rings;
- a ground-contacting tread located on said outer circumferential ring;
- a rim, said rim comprises a pair of rim halves, and said rim is located within said cylindrical space;
- and
- a hub, said hub is removably connected to said rim;
- wherein the rim halves are configured to be joined together and aligned to define a circumferential surface having a plurality of cavities about the circumferential surface;
- and
- wherein the inner circumferential ring defines a plurality of groups of axial ridges disposed about the inner circumferential ring, wherein each group of axial ridges is positioned and spaced to fit within a corresponding cavity within the circumferential surface defined by the rim halves when the rim halves are joined together.
