Abstract

A wheel rim assembly and components, systems, and methods thereof can have a rim base with at least one slot at an outer end portion thereof, a bead seat band radially outward of the outer end portion of the rim base, and at least one lock provided in the at least one slot. The bead seat band may be in direct contact with the outer end portion of the rim base. The lock can have a first portion that is provided in the slot of the rim base and a second portion that is outside of the slot. The second portion may be adjacent to the bead seat band. The wheel rim assembly may be free of or without a lock ring at the outer end portion of the rim base.

First claim

The invention claimed is:

1. A multi-component wheel rim for a tire of a construction or manufacturing vehicle, the multi-component wheel rim comprising:
a rim base having an inner end portion, an outer end portion opposite the inner end portion, and a middle portion extending between the inner end portion and the outer end portion in a direction of a central longitudinal axis of the multi-component wheel rim, a plurality of slots extending entirely through the outer end portion of the rim base, the slots being spaced apart from each other around a circumference of the rim base;
a pair of side rings, a first side ring of the pair of side rings circumscribing the outer end portion of the rim base and a second side ring of the pair of side rings circumscribing the inner end portion of the rim base;
a bead seat band circumscribing the outer end portion of the rim base and being circumscribed by the first side ring such that a portion of the bead seat band is between and in direct contact with the first side ring and the outer end portion of the rim base; and
a plurality of locks respectively provided in the plurality of slots of the outer end portion of the rim base, each of the locks being elongate with a base and a first projection, the first projection extending from a first side of the base and into the slot of the rim base, and the base being outside of the slot of the rim base,
wherein each of the locks has a pair of opposing inward sloping sidewalls, including an inner inward sloping sidewall and an outer inward sloping sidewall, the inner inward sloping sidewall directly interfacing with the bead seat band.

2. The multi-component wheel rim according to claim 1 , wherein the plurality of locks consist of two locks, three locks, or four locks equally spaced from each other around the circumference of the rim base.

3. The multi-component wheel rim according to claim 1 , wherein each of the locks is adapted to perform as a primary function preventing movement of the rim base, the bead seat band, and the first side ring in the direction of the central longitudinal axis of the multi-component wheel rim and as a secondary function preventing rotational movement of the rim base, the bead seat band, and the first side ring relative to each other.

4. The multi-component wheel rim according to claim 1 ,
wherein each of the locks includes a second projection extending from a second side of the base opposite the first side, and
wherein the second projections extend into respective ones of a plurality of cut-outs of the bead seat band.

5. The multi-component wheel rim according to claim 1 ,
wherein the bead seat band includes a plurality of cut-outs, and
wherein portions of the locks are respectively provided in the cut-outs.

6. A method regarding a multi-component wheel rim comprising:
providing a rim base of the multi-component wheel rim, the rim base having an inner end portion, an outer end portion opposite the inner end portion, and a middle portion extending between the inner end portion and the outer end portion, a plurality of slots extending through the outer end portion of the rim base, the slots being spaced apart from each other around a circumference of the rim base;
providing a bead seat band of the multi-component wheel rim, the bead seat band being adapted to, when assembled, circumscribe the outer end portion of the rim base such that a portion of the bead seat band is in direct contact with the outer end portion of the rim base; and
providing a plurality of locks respectively provided in the plurality of slots of the outer end portion of the rim base, each of the locks having a base and a first projection, the first projection extending from a first side of the base and being adapted to extend into the slot of the rim base when assembled,
wherein the multi-component wheel rim is without a lock ring when assembled.

7. The method according to claim 6 , wherein said providing the rim base, said providing the bead seat band, and said providing the plurality of locks are performed prior to inflation of a tire assembly provided circumferentially around the multi-component wheel rim to a driving pressure.

8. The method according to claim 6 , further comprising assembling the provided rim base, the provided bead seat band, and the provided plurality of locks such that the bead seat band circumscribes the outer end portion of the rim base such that the portion of the bead seat band is in direct contact with the outer end portion of the rim base and such that the first projection of each of the plurality of locks extends into the slot of the rim base.

9. The method according to claim 6 , wherein said providing the rim base, said providing the bead seat band, and said providing the locks are performed as part of a vertical mounting process of mounting the multi-component wheel rim.

10. A wheel rim assembly comprising:
a rim base having at least one slot at an outer end portion thereof;
a bead seat band radially outward of and in direct contact with the outer end portion of the rim base; and
at least one lock respectively provided in the at least one slot,
wherein each said at least one lock has a first portion that is provided in the at least slot of the rim base and a second portion that is outside of the slot and adjacent to the bead seat band, and
wherein the wheel rim assembly is free of a lock ring at the outer end portion of the rim base between the rim base and the bead seat band.

11. The wheel rim assembly according to claim 10 ,
wherein said at least one slot includes a plurality of slots spaced apart from each other around a circumference of the rim base, and
wherein said at least one lock includes a plurality of locks in one-to-one correspondence with respective ones of the plurality of slots.

12. The wheel rim assembly according to claim 11 , wherein the bead seat band includes a plurality of cut-outs in one-to-one correspondence with respective ones of the plurality of locks.

13. The wheel rim assembly according to claim 10 , wherein each said at least one lock is adapted to perform a primary function of preventing movement of at least the rim base and the bead seat band in a direction of a central longitudinal axis of the wheel rim.

14. The wheel rim assembly according to claim 10 , wherein each said at least one lock is adapted to perform a secondary function of preventing indexing of at least the rim base and the bead seat band relative to each other.

15. The wheel rim assembly according to claim 10 , wherein each said at least one lock includes a base as said second portion and a first projection as said first portion, the first projection extending from a first side of the base and into the at least one slot of the rim base, and the base being adjacent to the bead seat band.

16. The wheel rim assembly according to claim 15 ,
wherein each said at least one lock includes a second projection extending from a second side of the base opposite the first side,
wherein the bead seat band includes at least one cut-out, and
wherein each said second projection extends into a respective one of the at least one cut-out of the bead seat band.

17. The wheel rim assembly according to claim 15 , wherein the base of each said at least one lock has a pair of opposing inward sloping sidewalls, including an inner inward sloping sidewall and an outer inward sloping sidewall, the inner inward sloping sidewall directly interfacing with the bead seat band.

18. The wheel rim assembly according to claim 10 , wherein each said at least one lock i
