Abstract
The utility model relates to a high-load giant filling tire which comprises an outer tube, a filler and a rim, wherein the tread b of the outer tube adopts back arc design, and the sinking degree is 6-8mm; the height-to-width ratio H/B of the tire height H of a tire body to the section width B is 0.5-0.6; the filler is arranged between the inner part of the outer tube and the rim. With the adoption of the back arc design of the first tire, the tread of the tire is sunken by 6-8mm; after the tire is pressurized, the tread b becomes a flat arc, and the tire travels sunder a load; the tread b is in complete and uniform contact with the ground; the stress is uniform, and the stress area is large; the ground pressure is low, and the tire is high in bearing load; the single-tire load can be up to 35 tonnages. The second tire adopts flat design, and the section B of the tire adopts the flat design; the height-to-width ratio H/B of the tire is reduced to 0.51-0.6; the tire is a flat wide base tire; the outer diameter D of the tire is small, the section is wide, the tread is wide, and the diameter d of the rim is large; therefore, the high-load giant filling tire completely meets a requirement for adapting to high-load vehicles in a mine lot.
Description
One, technical field
The utility model relates to the huge filling tire of a kind of high load capacity, is the filling tire that a kind of tyre structure design exceeds conventional design.It is adapted at using on high load capacity large engineering vehicle.
Two, background technology
Along with the develop rapidly of domestic national economy, the economy on the ground such as colliery, metallurgical ore deposit, harbour also develops very fast.Engineering truck in enormous quantities is poured into China.And vehicle functions, tonnage improve constantly.The tire supporting with it is also in continuous update.Introduce advanced engineering truck since domestic colliery in 1996 and start, filling tire enters China with it, domesticly starts to research and develop various filling tires.The structure design of tire develops into gradually wide base by conventional design and designs.The operating needs of small dimension filling engineering tire during this design can meet.But the large-scale bracket carrier to current introduction, shovel board car, transport trolley are waited for bus, the filling tire using can not adapt to.Existing Design of Tire Structure over the ground specific pressure is large, and tire force is inhomogeneous, is difficult to bear more large-tonnage vehicle operating needs.Therefore on this vehicle, use temporarily solid tyre.Though solid tyre has the advantages such as bearing load is large, tire hardness is high, and cushion characteristic is poor, large to accessory damage capacitys such as vehicle main frames.So exploitation high load capacity filling tire is that large engineering vehicle is supporting imperative.
General Design of Tire Structure, enforcement face adopts positive arc R design.Radian height, generally at 8-14mm, adopts single arc R or two arc R design.This design is adapted at using on the engineering truck of low tonnage or medium-sized tonnage.This tire is in pressurising situation, and tread surface b outwards heaves, and wheel crown part is stressed large, and tread b ground pressure is inhomogeneous, and ground contact area is little, and specific pressure is large over the ground.Need tire overall diameter D little at current engineering truck, bear in the situation that load is large, this tire is difficult to adapt to.
Three, utility model content
The purpose of this utility model is to provide the huge filling tire of a kind of high load capacity.It is a kind of high load capacity filling tire using on large-scale bracket carrier, shovel car, transport plane, loader.It has solved the external import large-scale engineering machinery changing of tire matter of great urgency.Also for domestic-developed large engineering vehicle is paved the way.
The purpose of this utility model is achieved like this: the huge filling tire of a kind of high load capacity, it comprises: cover tire, charges, wheel rim, the tread b of cover tire takes anti-arc design, concavity h is 6-8mm, the height to width ratio H/B of the high H of tire, the wide B of section of tire carcass is 0.5-0.6, and charges are filled in cover tire and between wheel rim.
Feature of the present utility model:
First adopts anti-arc design, the recessed 6-8mm of tread surface, and after tire pressurising, tread b becomes flat arc, under tyre load, travel, the comprehensively even ground connection of tread b.Stressed evenly area of thrust surface are large, and specific pressure is little over the ground, and it is large that tire bears load, and single tire load can reach 35 tons.
The second tire is taked flat design, and tire section B takes flat design, the high H of tire, the wide B of section, and height to width ratio H/B is reduced to 0.51-0.6 by the 0.8-0.84 of wide base engineering tyre.Tire becomes flat wide base tire.D is little for tire overall diameter, and section is wide, the face width of travelling, and rim diameter d is large, is the use that needs in order to adapt to mining area high load capacity vehicle completely.Colliery is used height of car restricted, and vehicle body can not be high, and therefore tire overall diameter D can not be large.And the large large required rim diameter d of vehicle axle diameter of load is large.The high H of tire section reduces like this, and Design of Tire Structure must be taked flattening design.Flat tire has the face width of travelling, and ground contact area is large, and resistance to abrasion is good, and holding power is large over the ground, and grade climbing performance is good.Novel tire is better than the same specification radial-ply tyre of conventional design in hill climbing test.
Four, brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
Description of reference numerals is as follows: cover tire 1, charges 2, wheel rim 3, tread b, the high H of tire, the wide B of section, concavity h.
Five, detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
The huge filling tire of a kind of high load capacity of the utility model, it comprises: cover tire 1, charges 2, wheel rim 3, take anti-arc design according to tread surface b, concavity h is 6-8mm, carcass is taked flattening design, the height to width ratio H/B of the high H of tire, the wide B of section of tire carcass is 0.5-0.6, then cover tire 1 is arranged on wheel rim 3, is filled with charges 2 solidifies and form novel filling tire by certain pressure.
