Abstract

The utility model provides a rim strenghthened type solid tyre, it includes the rim of inner circle and the tire of outer lane, is equipped with the annular protruding ring of a plurality of circles at the surface of rim, and both sides the protruding ring that highly is higher than the intermediate position of protruding ring highly be equipped with the hook -like protruding of a plurality of barbs form on the protruding ring, the medial surface of rim is provided with a mounting flange and two supplementary ring flanges, the tire is the composite construction who is linked together through the mode that bonds by the polyurethane layer in the vulcanie layer of inboard and the outside, and wherein the thickness on vulcanie layer is eight centimetres at least. The utility model provides a traditional solid tyre's the low easy problem of trading of decreasing of intensity, improved the life of tire for it is finer and close that tire and rim combine, and the polyurethane layer in the outside makes tire wet skid resistance improved greatly.

Description

A kind of wheel rim heavier-duty band tyre

Technical field

The utility model relates to the band tyre that a kind of engineering truck uses.

Background technology

A kind of mine polyurethane giant solid tyre announced in Chinese patent 200920032252.7, this tire is solid construction, and bonding connection has the advantage of resistance to puncture.But in the process used, we find that the tire of this kind is prepared by a kind of material due to entirety, so elasticity is not fine, and there is band tyre and wheel rim in conjunction with acarpous problem, easy separation comes off, tire be separated with wheel rim or loosen after will be formed.

Existing band tyre be generally bonding connection between wheel rim, or crimping connection, form one, As time goes on the colloid of bonding use can be, cohesive force declines, cause coming off between the two, crimping connects, and makes the band tyre in outside form the predetermincd tension of outside tensioner, inner stress is strengthened, under long-term work state, cause the lax of band tyre, band tyre also can be made to come off on wheel rim.

Utility model content

The purpose of this utility model is to provide a kind of wheel rim heavier-duty band tyre, for improving the intensity of band tyre, especially solves the not high problem of tyre and rim contact strength.

The technical scheme in the invention for solving the technical problem is: a kind of wheel rim heavier-duty band tyre, comprises the wheel rim of inner ring and the tire of outer ring, it is characterized in that:

Be provided with the raised ring of some annular arrangements at the outside face of wheel rim, and the height of the described raised ring of both sides is higher than the raised ring height of midway location, and described raised ring is provided with the hamulus of some reversed acanthoids; The medial surface of described wheel rim is provided with a mounting flange and two auxiliary flange dishes;

Described tire is the composite structure linked together by bonding mode by the hard rubber layers of inner side and the layer of polyurethane in outside, and wherein the thickness of hard rubber layers is at least eight centimetres.

Further, described hard rubber layers and layer of polyurethane contact surface are smooth surface, and use sulfuration process to carry out process to connect.

Further, in described hard rubber layers, lay the high strength steel wire ring of annular in advance.

Further, described raised ring is four.

The beneficial effects of the utility model are: the problem that the low rapid wear of intensity that the utility model solves traditional band tyre changes, by processing at tire and wheel rim faying face place, especially hamulus is added, the structure be engaged is formed with tire, improve the service life of tire, what tyre and rim was combined is finer and close, more reliably solid, and the layer of polyurethane in outside makes tire tear resistance be greatly enhanced.

The medial surface of wheel rim is provided with a mounting flange and two auxiliary flange dishes, can improve the bulk strength of tire, and reduces deadweight, has good economic value.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of wheel rim;

Fig. 3 is the one distortion of Fig. 1.

In figure: 1 wheel rim, 11 raised rings, 12 hamulus, 13 mounting flanges, 14 auxiliary flange dishes, 2 hard rubber layers, 21 high strength steel wire rings, 3 layer of polyurethane.

Detailed description of the invention

As shown in Figure 1 and Figure 2, a kind of band tyre that can be used for mine engineering vehicle, comprise the wheel rim 1 of inner ring and the tire of outer ring, tire is wherein the composite structure linked together by bonding mode by the hard rubber layers 2 of inner side and the layer of polyurethane 3 in outside, wherein the thickness of hard rubber layers is more than eight centimetres, and the intensity of the layer of polyurethane 3 in outside is comparatively large, is driving surface, no matter at resistance to abrasion, anti tear shock resistance and load capacity are all better than rubber.Hard rubber layers 2 good springiness of internal layer, can increase the elasticity of band tyre.

And be provided with some raised rings 11 at the outside face of wheel rim 1, wherein the quantity of raised ring is four, highly differs, generally, four raised rings, increase gradually to opposite side height from side, four above-mentioned raised rings 11 can form the anti-drop structure of side direction, prevent coming off of side direction, especially, when Vehicular turn, the damage that lateral slip brings to tire more can be prevented preferably, as Fig. 1.Raised ring is provided with the hamulus 12 of some reversed acanthoids, wherein, the forming process of hamulus 12 is as follows: first utilize spader to manufacture hamulus on raised ring, the height of hamulus is at 2 cm, arrange along a direction, arranging according to uniform arrangement of this hamulus the best, then using thermatron to having hamulus and raised ring position is heat-treated, improving intensity.

For adapting to the dimensional characteristic of giant tire, the medial surface of wheel rim is provided with a mounting flange 13 and two heavier-duty auxiliary flange dishes 14, and wherein auxiliary flange dish is for increasing the intensity of entirety, and mounting flange is used for and wheel shaft is fixed installation.

Then use solid rubber to form tire core at the outer surface of wheel rim, wherein the outside face of hard rubber layers 2 is smooth surface, is convenient to the laying of outside layer of polyurethane.And use sulfuration process to process, improve anchoring strength between the two.

Further, as Fig. 3, also can in hard rubber layers 2 laying high-strength degree bead coil 21 in advance, high strength steel wire ring 21 forms annular, is centered around the periphery of hard rubber layers, and forms reinforcing flexible together, improve the hoop intensity of hard rubber layers, effectively prevent cracking.

Except the technical characteristic described in specification sheets, be the known technology of those skilled in the art.
