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.
Claims17
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 identical halves, and said rim is located within said cylindrical space;
- and
- a hub, said hub is removably connected to said rim;
- wherein said rim further comprises a ridge and a valley, and said hub further comprises a lug,
- wherein said ridge from one of the pair of identical halves is aligned with said ridge from the other of the pair of identical halves to form a cavity between said two pieces of said rim,
- wherein said lug is configured to interact with said cavity in order to limit rotation of said hub relative to said rim.
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 two identical halves, and said rim is located within said cylindrical space;
- and
- a hub, said hub is removably connected to said rim, wherein said hub is configured to transmit rotational power to said rim,
- wherein said hub is sandwiched between said two identical halves of said rim,
- wherein said rim further comprises a ridge and a valley, and said hub further comprises a lug,
- wherein said ridge from one of said two identical halves of said rim is aligned with said ridge from the other of said two identical halves of said rim to form a cavity between said two identical halves of said rim,
- wherein said lug is configured to interact with said cavity in order to limit rotation of said hub relative to said rim.
