Abstract
A dual, internal, pneumatic, boltless beadlock assembly for effectively securing a tire to a rim is disclosed. A pneumatic beadlock assembly is disposed inside a tire and mounted on a rim. A pneumatic beadlock assembly exerts a force on the two circumferential inner beads of a tire such that the tire stays in secure contact with the rim, even when the inflation pressure of the tire is not sufficient to lock the tire to the rim.
Claims20
A beadlock air channel (160) comprising:
- a. an elongated, air channel body (161) being sealed on all sides, including a sealed first end (162), except for an open second end (163) of the air channel body (161);
- b. a tire valve stem (164) disposed on the sealed first end (162) of the air channel body;
- and
- c. an air passage (165) having at least a portion thereof disposed inside the air channel body (161), wherein a first end (166) of the air passage is disposed at or adjacent to the tire valve stem (164) and a second end (167) of the air passage is disposed at, or adjacent to, or extending from the open second end (163) of the air channel body, wherein the air passage (165) comprises two parallel rows of bumps (168) having an air passage gap (169) disposed between said rows of bumps (168).

A beadlock assembly (100), housed within a tire (102) and surrounding a rim (104) upon which the tire (102) is mounted, the beadlock assembly (100) comprising:
- a. an inner tube (134), encircling the rim (104), having an inner tube valve stem (106) mounted on the rim (104);
- b. a beadlock case (108) encompassing the inner tube (134), wherein the beadlock case (108) comprises:
- i. a beadlock tread (110) disposed along an outer circumference of the beadlock case (108), wherein the beadlock tread (110) has a first outer circumferential edge (120) and a second outer circumferential edge (121);
- ii. a first beadlock sidewall (122) disposed between the first outer circumferential edge (120) of the beadlock tread (110) and the rim (104);
- iii. a second beadlock sidewall (138) disposed between the second outer circumferential edge (121) of the beadlock tread (110) and the rim (104);
- iv. a first beadlock bead (140) disposed on an inner circumferential edge (124) of the first beadlock sidewall;
- and
- v. a second beadlock bead (142) disposed on an inner circumferential edge (125) of the second beadlock sidewall;
- and
- c. a beadlock air channel (160) comprising:
- i. an elongated, air channel body (161) being sealed on all sides, including a sealed first end (162), except for an open second end (163) of the air channel body (161);
- ii. a tire valve stem (164) disposed on the sealed first end (162) of the air channel body;
- and
- iii. an air passage (165) having at least a portion thereof disposed inside the air channel body (161), wherein a first end (166) of the air passage is disposed at or adjacent to the tire valve stem (164) and a second end (167) of the air passage is disposed at, or adjacent to, or extending from the open second end (163) of the air channel body, wherein the air passage (165) comprises two parallel rows of bumps (168) having an air passage gap (169) disposed between said rows of bumps (168);
- wherein the tire valve stem (164) is mounted to the rim (104), wherein the beadlock air channel (160) joins a main air chamber (130) and the tire valve stem (164) mounted to the rim (104), wherein the main air chamber (130) is an air tight space between the tire (102), when inflated, and the rim (104), wherein the tire valve stem (164) allows air to enter and exit the main air chamber (130) through the air passage (165),
- wherein the beadlock assembly (100) is housed in the tire (102) such that the beadlock assembly (100) contacts the tire (102) at two inner circumferential tire beads (136), wherein the inner tube (134) disposed within the beadlock assembly (100) is inflated from the inner tube valve stem (106), wherein the beadlock assembly (100) exerts a force on the two inner circumferential tire beads (136) such that the tire (102) stays mounted on the rim (104) even when the inflation pressure of the tire (102) is not sufficient to lock the tire (102) to the rim (104),
- wherein the two parallel rows of bumps (168) allow for air to flow through the air passage (165) even when the tire beads (136) are pressed against the beadlock beads (140, 142), wherein the air passage gap (169) is sufficiently wide to allow air to pass through the air passage during inflation or deflation while preventing the inner tube (134) from expanding into the air passage gap (169) and stopping air flow, wherein the air channel body (161) contours to a profile of the rim when the tire (102) is mounted thereon.
