This technology generally relates to tire beadlock systems and, more particularly, to wheel-internal double beadlock systems and methods thereof
All vehicle wheels use some version of a “beadlock” system. Tires and wheels are designed so that when the tire is inflated, the tire pressure pushes the bead of the tire against the inside of the wheel rim so that the tire stays on the wheel and the two rotate together. The beadlock system is designed to keep the tire in place on the wheel in situations when air pressure is intentionally or unintentionally insufficient, i.e. low or no air pressure, to hold the bead of the tire in place. For example, in certain driving situations, such as certain types of off-roading, drivers may want extremely low tire pressure for traction or other reasons.
As such, there are numbers of prior designs of beadlock systems. The most common is a “bump” B1 and B2 adjacent each side on the wheel rim TR1, that requires high air pressure to overcome, and “pop” the tire over as shown in traditional beadlock system illustrated in
Another common prior design of a beadlock system is to have an external ring ER bolted with an internal ring IR inside the tire, so the tire wall is captured on the tire rim TR2 as shown in the outside beadlock system illustrated in
An internal double beadlock system includes a centralized inner ring and one or more tire positioners. The one or more tire positioners are coupled to extend out from each side of the centralized inner ring. Each of the tire positioners has a length to detachably engage with a portion of an inner tire wall on each side of a tire positioned on a tire rim while being shorter than a width of the tire rim.
A method for making an internal double beadlock system includes providing a centralized inner ring and coupling one or more tire positioners to extend out from each side of the centralized inner ring. Each of the tire positioners has a length to detachably engage with a portion of an inner tire wall on each side of a tire positioned on a tire rim while being shorter than a width of the tire rim.
A method for installing a tire on a rim includes coupling a centralized ring of an internal double beadlock system to a central portion of a tire rim. One or more tire positioners extend out from each side of the centralized inner ring. Each of the tire positioners has a length to detachably engage with a portion of an inner tire wall on each side of a tire positioned on a tire rim while being shorter than a width of the tire rim. The end portion of the tire wall on each side of the tire is positioned in a space between each end of the tire positioners and outer edges of the tire rim to form a detachable engagement and then at least partially inflating the tire.
Examples of this technology provide a number of advantages including providing a secure, lightweight, and effective wheel-internal double beadlock system suitable for all types of driving applications. With examples of this technology, the wheel-internal double beadlock system is advantageously designed to keep both sides of the tire in place (inside and outside sides) at any tire pressure. As a result, both walls of the tire are supported internally and will not come off their position. Additionally, with examples of the technology the wheel-internal double beadlock system has less weight and overall cost than the outside beadlock systems. Further, with examples of this technology, high air pressure is not required to seat the tire “over” the bumps, as is required for the traditional beadlock system (which can be difficult and dangerous).
An example of a wheel-internal double beadlock system 100 is illustrated in
Referring more specifically to
This example of the wheel-internal double beadlock system 100 has four tire positioners, two of the tire positioners 104(1)-104(2) are visible in
In this example, the structure and operation of the four tire positioners is the same, so for ease of discussion the following exemplary description references tire positioners 104(1)-104(2) and that description is applicable to the other tire positioners not visible in these figures. Each of the tire positioners 104(1)-104(2) are coupled to extend out perpendicularly from each side of the centralized inner ring 102, although the tire positioners 104(1)-104(2) could be coupled to extend out in other orientations. Each of the tire positioners 104(1)-104(2) also has a length shorter than a width of the tire rim 200, but long enough to detachably engage with a portion of an inner tire wall on each side of a tire (not shown). An outer wall of on each side of the tire (not shown) engages with tire rim edges 204(1) and 204(2) of tire rim 200 to provide the double beadlock on both sides of the tire. Further, each portion of the tire positioners 104(1)-104(2) extending out from the centralized inner ring 102 is spaced from the surface of the tire rim 200 and comprises on each side an elongated arm 106(1) and 106(2) with an end engagement section 108(1) and 108(2) that each extend in a different direction from the elongated arm 106(1) and 106(2) and the surface 202 of the tire rim 200 to be positioned to face a portion of an inner tire wall on each side of the tire (not shown) and provide a matching surface size, in this example, to engage and retain the tire. In this example, the elongated arms 106(1) and 106(2) and end engagement section 108(1) and 108(2) comprise one piece, although in other could be separate elements which are coupled together. Each of the tire positioners 104(1)-104(2) is also sized and shaped to provide a level of spring tension on an inner wall of each side of a tire (not shown) that in conjunction with the engagement of the tire rim edges 204(1) and 204(2) of tire rim 200 with an outer wall of each side of the tire (not shown) retains the tire on the rim under any tire pressure including for example no pressure. By way of example, the shape and/or size of the elongated arms 106(1) and 106(2) could be customized to provide different levels of spring tension. With these elongated arms 106(1) and 106(2) with a customized level of spring tension, one or more of the tire positioners could be replaced to customize a level of spring tension for particular applications and conditions.
