Abstract
The invention relates to an engineering machinery tire and an agricultural machine tire, and more specifically relates to a water-filling tire, which belongs to the rubber processing technical field. The water-filling tire is characterized in that a calcium chloride-containing solution is filled in the tire for replacing inflation, 0.6kg of calcium chloride is added in every liter for mixing to obtain a solution, the calcium chloride density is 1.37Kg/dm<3>. The volume of the calcium chloride solution filled in the water-filling tire is no more than the total volume of the tire by 90%; and the volume of the calcium chloride solution filled in the tubeless tire is no less than total volume of the tire by 75%. The calcium chloride solution is filled in the tire for replacing the inflation, the ballast efficiency of the tire is increased, so that the traction performance of the tire can be enhanced, and the tire has antifreeze function in winter. When the water-filling amount of the tire accounts for 10% of the weight of the vehicle, the tractive force can be increased by about 10%; the machinery counter weight is increased, the center of gravity of the machine is reduced, and the mechanical stability and driving smooothness can be increased.
Description
Technical field
The present invention relates to a kind of off-the-road tyre and farm machine tire, be specifically related to a kind of water-ballasted tire, belong to the rubber processing technical field.
Background technology
One of principal character of off-the-road tyre and farm machine tire is exactly to transmit larger tractive force, the formula of tractive effort T=A*C+W*tg φ that is transmitted by tire
T-tractive force; A-ground contact area; C-soil coefficient of cohesion; W-tyre load: φ-soil coefficient of friction.
The weight (W) that tire-contact area (A) and tire act on soil has a significant impact the tractive property that tire obtains.Be filled with a certain amount of water in tire, can make tire increase ground contact area and increase the gross pressure that lands, thereby improve the tractive property of tire.Simultaneously, water-filling in tire replaces inflation, has been equivalent to increase mechanical counterweight, and the center of gravity of machinery is reduced, and can increase the stability of machinery and the stationarity that runs.
Summary of the invention
The objective of the invention is in order to strengthen the tractive property of tire, a kind of water-ballasted tire is provided, be filled with certain density calcium chloride solution and replace inflation in tire, this is because the relative density of calcium chloride is large, can improve the ballast efficient of tire, thereby improve the tractive property of tire, simultaneously in the winter time can also be antifreeze.The concentration of calcium chloride solution and relative density have a significant impact the height of its chill point.Solution concentration is higher, and relative density is larger, and its chill point is lower.Add the calcium chloride of 0.6kg that water can not frozen more than-45 ℃ (53 ℉) in every premium on currency, corresponding calcium chloride density is 1.37Kg/dm3.By evidence, when the tire filled water amount accounts for complete vehicle weight 10%, can improve tractive force 10% left and right; Can increase the counterweight of machinery, the center of gravity of machinery is reduced, can increase the stability of machinery and the stationarity that runs.
The present invention realizes with following technical scheme: a kind of water-ballasted tire, it is characterized in that: this water-ballasted tire is to be filled with the solution that contains calcium chloride to replace inflation in tire, add the calcium chloride of 0.6kg to make it be mixed into solution in every premium on currency, calcium chloride density is 1.37Kg/dm3.
The volume that is filled with calcium chloride solution in described water-ballasted tire is no more than 90% of tire total volume; The volume that tubeless tires is filled with calcium chloride solution is no less than 75% of tire total volume.
Advantage of the present invention is: replaces inflation by be filled with calcium chloride solution in tire, can improve the ballast efficient of tire, thereby improve the tractive property of tire, and simultaneously in the winter time can also be antifreeze.When the tire filled water amount accounts for complete vehicle weight 10%, can improve tractive force 10% left and right; Can increase the counterweight of machinery, the center of gravity of machinery is reduced, can increase the stability of machinery and the stationarity that runs.
The specific embodiment
Embodiment,
Be filled with the solution that contains calcium chloride and replace inflation in tire, add the calcium chloride of 0.6kg to make it be mixed into solution in every premium on currency, calcium chloride density is 1.37Kg/dm3.
The volume that is filled with calcium chloride solution in described water-ballasted tire is no more than 90% of tire total volume; The volume that tubeless tires is filled with calcium chloride solution is no less than 75% of tire total volume.
Water-filling (calcium chloride solution) Noticed Problems:
1, the water-filling vehicle muddy terrain competence exertion effect that is applied to sandy soil and hard soil and hardcore is arranged.
2, the external diameter of water-filling rear tyre is slightly smaller than full air-inflation tyre, and section width is a bit larger tham full air-inflation tyre.
3, inner tube of a tyre rubber cushion, the inner tube of a tyre chew son to use meet GB CJ08(Z1-07-1), CJ09(Z1-07-2) or the gas-liquid inner tube valve of American Standard TR218A, TR220A standard, in case by the solution corrosion that is filled.
Claims (2)
1. water-ballasted tire is characterized in that: this water-ballasted tire is to be filled with the solution that contains calcium chloride to replace inflation in tire, adds the calcium chloride of 0.6kg to make it be mixed into solution in every premium on currency, and calcium chloride density is 1.37Kg/dm3.
2. water-ballasted tire according to claim 1, it is characterized in that: the volume that is filled with calcium chloride solution in described water-ballasted tire is no more than 90% of tire total volume; The volume that tubeless tires is filled with calcium chloride solution is no less than 75% of tire total volume.
