The present invention is relates to a 2 or more piece polymer material but not limited to any polymers only, bead lock safety device suitable for vehicle wheels fitted with tube type/tubeless type of Tyres, and is appropriately suitable for 3 piece flat base wheel rims with lock ring type of arrangement. The lock ring types of Wheel rims are more susceptible to disassembly under lower/reduced air pressures or under influence of side impacts unless the tyre beads are restrained in position. A tyre may lose pressure/voluntarily air pressure is reduced to increase the foot print of tyres under such circumstances the tyres traverse freely or uncontrollably becoming twisted and unstable that can cause vehicle to roll over at normal speeds. Single piece bead locks rings made from soft materials like rubber are widely in use and more suitable for bolt on wheel types
The present invention is improvement over existing rubber ring bead lock technology, not only it is stiffer at lower thickness that indirectly reduces the overall weight of bead lock system, but also because of 2 piece configuration easy to assembly inside the tyre, because of the tyre of locking arrangement the whole will function as a single unified ring, that is recyclable, cost effective, stronger in function and easy to assembly by normal tyre technician
A beadlock or bead lock is a mechanical device that secures the bead of a tyre to the wheel Rim. Tyres and wheels are designed so that, when the tyre is inflated, the tyre pressure pushes the bead of the tyre against the inside of the wheel rim so that the tyre stays on the wheel and the two rotate together. In situations where tyre pressure is insufficient to hold the bead of the tyre in place, a bead lock is needed.
There are several styles of bead locks. For 4-wheel drive vehicles, a ring with a number of bolts around the circumference is used to clamp the tyre to the wheel, a different style of bead lock can be used that is similar to an inner tube which is inflated to press the tyre against the wheel and a round circular rubber ring is also used as bead locks.
Bead locking devices were developed to ensure that, when a tyre is run at a low air pressure or zero pressure, the tyre will not run off of the wheel or spin freely on the wheel, rendering the vehicle immobile. Both external and internal bead locking devices are currently used for this purpose. An external bead lock consists of a ring mounted outside of the tyre and rim flange, which is attached to the rim flange with hardware. {See, e.g.,
The disclosure of WO/2012/006069 to HUTCHINSON S. A is a improved bead locking apparatus and system is based on the provision of an expandable single and/or dual bead lock device with a bead compression ring that thrusts against the bead(s) of the tyre from the inside and is braced against and via the drop center of the wheel rim and/or an opposing bead compression ring. The ring or rings are caused to press against the tyre bead(s) via mechanical means actuated by a screw driver or similar implement. In single bead lock designs, the said implement can be inserted between the bead and rim on the side of the wheel opposite from that where the compression ring is located.
The following description is of the best presently for the purpose of illustrating the general principles of invention and not to be taken in a limited sense
It is an aspect of the present invention to provide a more efficient and Easy to fit, two piece mechanical Bead lock system, suitable for 3 piece flat profile wheel rims with lock ring type locking as defined in one or more of the appended claims and as such, having the capability of accomplishing one or more of the following subsidiary objects that can also takes side on impacts without lock ring imparting the wheel integrity.
An aspect of the present invention is easy to assemble and disassemble when compared to prior technologies.
Another aspect of the present invention is that bead lock position locking helps to maintain wheel balancing intact combined with position locking mechanism
Yet another aspect of the present invention is that the new invented bead locks ends are Rubber capped the current invention has dual advantage of hard structure and soft end that provides required rigidity but also to prevents so called tyre damage.
Yet another aspect of the present invention is light in weight.
Yet another aspect of the present invention is recyclability
Yet another aspect of the present invention is applicable for Tubeless tyres with multi piece wheel rims with lock rings, Split ring wheel rims, Bolt on type wheel rims and Disc Centre type wheel rims.
The current invention is also related to a two or more piece easy to fit safety device called bead lock when used in combination with tube, tubeless, custom design wheel rim and Tube type or tubeless type tyre, radial or bias provides increased traction and braking when operating under low tyre pressure conditions required for greater traction on rocks, sand, mud snow, loose dirt, or any off-road surface, it improved steering control and minimize the chances of rollover caused by the unseating of the tyre bead in 3 piece lock ring type flat wheel rims and other multi piece tube type and tubeless versions of tyres.
The present invention relates to a Easy to fit, two or more piece mechanical Beadlock system, suitable for 3 piece flat wheel rims with lock ring type locking, that requires robust mechanism that can withstand side impacts effectively without crimping inside that may cause the Lock ring to become loose or detached from the wheel rim, exposes the vehicles to safety scare during reduced or low pressure movement required for moving in a particular terrain that requires higher foot print. The ends of such polymer Bead lock are capped with Rubber, Silicone or softer materials that are compatible with soft components of tyres
As the current two or more piece bead lock system also has a position locking system incorporated that prevents rotation of the bead lock that prevents wheel balancing issues.
The current system is more relevant to 3 piece flat wheel rims with Lock ring type where positive locking is lacking, but equally applicable to bolt on split wheel rims and tube type wheel assemblies requiring lateral rigidity
The invention will now be described with reference to the accompanying drawings.
