Abstract
A vehicle tire balancing material comprising beads (1) formed from a first material (1′) having a higher tribo-electric work function, the beads (1) further having a permanent coating (1″) formed from a second material having a lower tribo-electric work function.
Claims19
A vehicle tire balancing material comprising beads formed from a first material having a higher tribo-electric work function than the tire material, said beads having a permanent coating formed from a second material having a lower tribo-electric work function than said first material.
A balancing material as claimed in any of claims 1 to 9, wherein said beads are in the range between 25 to 45 thousands of an inch (0.64 to 1.15 mm) in diameter.
A method of correcting the imbalance in a wheel assembly comprising the steps:
- (a) injecting a desired amount of a vehicle tire balancing material comprising beads formed from a first material having a higher tribo-electric work function, said beads having a permanent coating formed from a second material having a lower tribo-electric work function into the hollow interior of a stationary tire mounted to a wheel rim,
- (b) pressurizing the air in the tire to a desired level,
- (c) setting in motion the tire, and
- (d) the tire balancing material migrating within the interior of the tire and coming to a stop on the lining of the tire at a position or positions so as to counterbalance the imbalance in the wheel assembly and remaining at those positions by electrostatic cling.
A method of correcting the imbalance in a wheel assembly comprising the steps:
- (a) introducing a predetermined amount of a vehicle tire balancing material comprising beads formed from a first material having a higher tribo-electric work function, said beads having a permanent coating formed from a second material having a lower tribo-electric work function into the tire well of an unmounted stationary tire,
- (b) mounting the tire,
- (c) pressurizing the air in the tire to a desired level, and
- (d) setting in motion the tire, whereby the tire balancing material migrates within the interior of the tire and comes to a stop on the lining of the tire at a position or positions so as to counterbalance the imbalance in the wheel assembly.
A method of correcting the imbalance in a wheel assembly comprising the steps:
- (a) introducing into a well of a tire prior to the tire being mounted at least one pressurized sealed package containing therein a predetermined amount of a vehicle tire balancing material comprising beads formed from a first material having a higher tribo-electric work function, said beads having a permanent coating formed from a second material having a lower tribo-electric work function,
- (b) inflating the tire to a desired pressure level and such a way so as to break open said sealed package whereby said tire balancing material is released into the tire well, and
- (c) setting in motion the tire whereby the released tire balancing material migrates within the inner periphery of the tire and comes to a stop on the lining of the tire at a position or positions so as to counterbalance the imbalance in the wheel assembly.
