Abstract
A load-bearing tyre with air-tight band pad and no inner tube features that an air-tight layer playing the role of inner tube is attached to the inner surface of tyre, the band pad with magnetic (or iron) powder-rubber layer is overlapped with the tyre edges with magnetic (or iron) powder-rubber layer to form a magnetic air tightness, and the air valve is arranged on said band pad.
Description
Technical field
The present invention relates to a kind of load-carrying tubeless tires, be applicable to that the radial that adopts the multi-piece type flat base rim, the load-carrying tube-tyre of two kinds of structures of oblique change tubeless tires into the close gas of rim strip.
Background technology
As everyone knows, tubeless tires has that the heat of giving birth to is slow, rapid heat dissipation, can reduce tire Yin Shengre and the damage that causes, the softer cushion characteristic that can improve tire of carcass, losing heart and slowly be difficult for blowing out in perforation back, can improve the safety of travelling, quality is less preceence such as can save material.Therefore, the motor tire of world developed country turns to developing direction with inner tube free invariably.
The principal feature of so-called tubeless tires is without the inner tube of a tyre and rim strip, has the good rubber air-retaining liner of one deck air-tightness to play inner tube of a tyre effect on the tyre cavity wall.Prior art adopts the interference fit design to make the tire bead banding guaranteeing airtight between tire and wheel rim on the wheel rim, has the deep-well rim of constant slope for the dismounting tire also must adopt bead seat easily.Therefore, existing load-carrying tube-tyre changes inner tube free into, and wheel rim will change shape, tire and also will redesign, and the specification size and the expression symbol of tire also need change, and when changing the inner tube free of same specification into as the 9.00-20 tire, claim 10-22.5.This brings many difficulties and resistance for the inner tube freeization of band tire, because China produces the bogie of use at present and with other vehicle of its chassis refit, what the overwhelming majority adopted is multi-piece type flat base rim and tube-tyre, carry out the band tire inner tube freeization with prior art, not only to eliminate large quantities of tires and wheel rim, also be associated with some techno-economic questions such as tire production equipment and car chassis.
Prior art tubeless tires and wheel rim air tight structure design, require tire bead should bear inflation pressure, lock torque, side force and centnifugal force etc. bear again airtight, so tyre bead and wheel rim driving fit difficulty, fragile gas leakage.Existing tubeless tires can not dismounting owing to the non-specialized equipment of the reason of airtight construction, and the driver is changing of tire voluntarily, can not exchange with tube-tyre that to wait its poor practicability also be the desirable not to the utmost part of prior art.Therefore, the load-carrying tube-tyre changes inner tube free into, and particularly truck bias tyre changes inner tube free into and remains important research project one.
Summary of the invention
The purpose of this invention is to provide a kind of load-carrying tubeless tires with the close gas of rim strip, make the load-carrying tube-tyre of existing radial, two kinds of structures of oblique, tire, wheel rim need not change the shape redesign can change tubeless tires into, utilize existing tire equipment, technology to produce, both overcome existing tubeless tires and wheel rim driving fit difficulty, the perishable gas leakage of tyre bead, non-specialized equipment can not dismounting etc. deficiency, the advantage that possesses tubeless tires again can also be exchanged with tube-tyre and be used.
For achieving the above object, technical scheme of the present invention is that the polymer magnetic material is applied to tire, the magnetic that promptly is used for rim strip and tire bead is tightly connected, and the air-tightness of tire is that the airtight construction of air-retaining liner on the roller tire internal chamber wall and rim strip and tyre bead obtains, thereby realizes inner tube free.
Load-carrying tubeless tires with the close gas of rim strip comprises tire, wheel rim, rim strip and tire tube valve, be applicable to the radial that adopts the multi-piece type flat base rim, the load-carrying tube-tyre of two kinds of structures of oblique changes tubeless tires into, feature of the present invention is: the tyre cavity wall is provided with the rubber air-retaining liner and replaces original squeegee, the lateral wall of the superimposed place rim strip of rim strip and tyre bead is provided with magnetic or iron powder rubber layer, the tyre bead interior side-wall surface is provided with iron powder or magnetic rubber layer, also can opposedly set up the magnetic rubber layer of the opposite sex separately, the superimposed place magnetic of described rim strip and tyre bead is tightly connected.
It is characterized in that: also be provided with air-retaining liner on the described rim strip, described tire tube valve is located on the rim strip.
It is characterized in that: described magnetic rubber layer is the composite polymer magnetic substance, and described iron powder rubber layer is a polymer matrix composite.
Beneficial effect
Owing to adopted such scheme, the present invention has following beneficial effect compared with prior art:
Because tire of the present invention, wheel rim need not change the shape redesign, therefore utilize equipment, the technology of existing tire to produce, do not relate to car chassis yet.
Because the present invention adopts rim strip and the design of the superimposed magnetic bonded assembly of tyre bead airtight construction, therefore be applicable to that the load-carrying tube-tyre of radial, two kinds of structures of oblique changes tubeless tires into, and prior art tire and wheel rim driving fit difficulty have been overcome, the fragile gas leakage of tyre bead, non-specialized equipment can not dismounting etc. deficiency.
Because thereby the present invention uses the airtight construction that improves band tire to realize inner tube free, therefore both kept the advantage of tube-tyre, possessed the advantage of tubeless tires again, can also exchange use by two kinds of tires.
Accompanying drawing is a section structure scheme drawing of the present invention:
Among the figure: 1, tire, 2, air-retaining liner, 3, tyre bead, 4, rim strip, 5, air-retaining liner, 6, tire tube valve, 7, wheel rim, 8, wheel rim, 9, ring washer, 10, magnetic or iron powder rubber layer, 11, iron powder or magnetic rubber layer.
Embodiment
With reference to accompanying drawing, the internal chamber wall of tire 1 body is provided with the good rubber air-retaining liner of air-tightness 2 and replaces original squeegee and play inner tube of a tyre effect, on the lateral wall of rim strip 4 and the rim strip at the superimposed place of tyre bead 3, be provided with magnetic or iron powder rubber layer 11, the madial wall of tyre bead 3 is provided with iron powder or magnetic rubber layer 10, the magnetic rubber layer 10 that also can opposedly set up the opposite sex separately, 11, airtight and the repeated disassembled and assembled of this of assurance but the superimposed place magnetic of rim strip 4 and tyre bead 3 is tightly connected, also be provided with air-retaining liner 5 on rim strip 4 bodies, tire tube valve 6 is located at can be directly to the tire interacvity air-filling on the rim strip 4, wheel rim 7 is by detachable wheel rim 8, breakaway-element back-up ring 9 is formed, and the multi-piece type flat base rim comprises two-piece type.Behind tire 1 fit on rim strip 4 and the wheel rim 7, rim strip 4 and tyre bead 3 leak-tight joint under the effect of magnetic function, can not only guarantee airtight when tire 1 inflation is initial, charge into airtight when rim strip 4 is fitted in more closely and guarantees on tyre bead 3 and the wheel rim 7 that tire 1 dynamically under the effect of air pressure along with compressed-air actuated.
