The present disclosure generally relates to a wheel design for pneumatic tubeless tires that convert from a standard tubeless tires mounted design to a locked outer bead wheel design.
Conventional wheels for mounting tubeless tires have a hub formed with peripheral flanges for abutting and sealing the beads on each side of the tubeless type tires. A frequent problem with these wheels is that when cornering, the centrifugal force on the tire can cause a separation of the bead from the rim, resulting in the loss of air. This deflates the tire, requiring reinflation of the tire at frequent intervals. Alternatively, some users of vehicles may prefer to change to low tire pressure when those users engage in off-road driving in order to obtain optimum traction.
For example, when driving in sandy conditions, it is generally desirable to have low pressure within the tires in order to obtain the desired traction. A traditional wheel cannot keep a tire bead firmly locked to the rim when the pressure within the tire is low. It is undesirable to have a tire which separates from the wheel.
The wheels that have been previously designed for such low pressure tires provide a means to clamp the beads of a tire. These wheels, however, provide a flange on the hub which cooperates with another member to apply axial forces on either side of the bead. However, these clamping components are generally of a planar construction and have a heavy weight. These wheels furthermore are designed for use only with low pressure tires. Furthermore, this type of design generally requires a very complicated configuration in order to hold the tire in place.
It is further undesirable to change the wheels every time the tires are changed from a higher pressure to a lower pressure. This is a time consuming, labor intensive, and expensive system to have on a vehicle which uses both higher tire pressure and lower tire pressure.
Therefore, it is an object of the present disclosure to provide a wheel design that can be used for mounting pneumatic tubeless tires that can convert from the standard tubeless tires to a wheel having a locked outer bead design such that the wheel can hold the same tire in place whether the pressure within the tire decreases or increases.
An outer bead lock wheel for use with pneumatic tubeless tires is provided according to the embodiment(s) disclosed herein. The outer bead lock wheel of the present disclosure provides for wheel and tire flexibility between off-road vehicle capability and on-road vehicle capability by securing the tire to the wheel regardless of the change in tire pressure. The outer bead lock wheel of the present disclosure includes a wheel base having a flange which is operatively configured to receive one of a decorative ring or a functional ring. The decorative ring may be mechanically affixed to the wheel base, and the functional ring may also be mechanically affixed to the wheel base.

In this embodiment, the outer bead lock wheel 10 of the present disclosure includes a wheel base 14 formed of a metal such as steel, aluminum or an alloy. As shown, the wheel base 14 and the decorative ring 12 may implement approximately twelve mechanical fasteners 16 given that the decorative ring 12 is not a load bearing ring. The mechanical fasteners 16 may fasten either the decorative ring 12 or the functional ring 30 by inserting mechanical fasteners in apertures 50. The decorative ring 12 may be formed of aluminum. However, in such an event, the wheel base 14 is also likely to be formed of aluminum as well.
The mechanical fasteners 16 may fasten either the decorative ring 12 or the functional ring 30 to the wheel base 14 by inserting mechanical fasteners 16 in apertures 50 (or bores 52) defined in the wheel base 14, the functional ring 30 and the decorative ring 12 as shown in

With reference to
The horizontal surface 32 and the vertical surface of the functional ring 30 form a recess 36 wherein the recess 36 is operatively configured to receive a lower edge 42 of a relatively lower pressure tire 26. As tire pressure is decreased, it is desirable to clamp or lock the tire 26 in position to prevent separation between the tire 26 and the wheel in an off-road driving condition.
With reference to
It is to be understood that the decorative ring 12 may be formed from a variety of materials, including but not limited to aluminum or steel. The functional ring 30 may be an anodized ring in yet another non-limiting example. Furthermore, in yet a few non-limiting examples, the fastening means 40 or the plurality of mechanical fasteners 16 may be either internal hex fasteners 24 or M10 Washer fasteners 28. However, other fastening means may be implemented which mechanically tighten either the decorative ring 12 or the functional ring 30 to the wheel base 14.
