Abstract

The utility model provides a structure improved tyre, particularly to a change for the packing structure in the tyre, which is mainly characterized in that packing with foaming ability is directly filled in the tyre, so the packing used as an inner tyre is completely sealed with the treads of the inner tyre of the tyre, and the tyre is free from air inflation. No slippage happens between the packing and the tyre, and the conditions of tyre burst caused by external force (such as sharp objects) do not happen.

Description

The tire of structural development

The utility model provides a kind of tire of structural development, particularly does one at the packing structure in the tire and changes, and tire is reached exempt from inflation, and non-slip between weighting material and tire, also can not be subjected to external force (as sharp object) and the situation that causes blowing out takes place.

The general tire that can see on the market roughly is divided into three major types such as air tyre, solid tyre and filling tire, wherein air tyre is divided into again two kinds of the inner tube of a tyre and inner tube free, there is the air tyre system of the inner tube of a tyre that gas is charged in the inner tube of a tyre, by the inner tube of a tyre cover tire is propped up, such defeated tire very easily causes blowing out of moment because of the influence that is subjected to external force (as sharp object), and then the possibility of causing danger is arranged; And tubeless air tyre is directly to use a performance tires and wheel rim fit, again gas directly is poured in the carcass inside, if such tire is when being subjected to external force (as sharp object), the slow pressure release of gas meeting in the tire, if but during loads, the air pressure in the performance tires also can quick pressure releasing cause danger; Solid tyre adopts one-body molded in processing procedure, because such tire becomes a solid therefore can not blow out, yet resistance to abrasion is low, Heavy Weight easily produces shortcomings such as distortion because of the difference of using material has.In addition, fill tire and be divided into a cover tire and a filling inner tube of a tyre, it is mainly filled in a filling inner tube of a tyre that is solid shape in one cover tire, and such tire pushes through in the journey quite difficult at plug, usually causing the cover tire plug to push through in the journey is out of shape, and this filling inner tube of a tyre is on duty mutually with the closed intensity of this cover tire, often causes this filling inner tube of a tyre and this cover tire to be the partly accepting and partly rejecting shape that contacts in the vehicle ' process, and has influence on safety in the vehicle ' process.

In sum, known its shortcoming of various tire is:

One. because the structure of known air tyre, when being subjected to external force (as sharp object), and cause blowing out of moment, and then cause danger.

Two. known solid tyre is integrated tire, because of being subject to the problem of material, will cause the insufficient strength and the friction force deficiency of tire, and can't bear to use.

Three. known filling tire pushes through in the journey quite difficult in plug, usually causing cover tire to be got in the journey at plug is out of shape, and this filling inner tube of a tyre is on duty mutually with the closed intensity of this cover tire, often cause filling the inner tube of a tyre in the vehicle ' process and be the partly accepting and partly rejecting shape that contacts, and influence the safety in the vehicle ' with this cover tire.

The utility model promptly is at doing a change on its structure of known tire, and directly the weighting material with the tool foaming effect is injected by the filling nozzle in the wheel rim, makes weighting material direct foaming in tire, and the interior tread of relief weighting material and tire fits tightly fully.

The design people examines through constantly thinking to grind especially at known shortcoming, and experience test improvement is many times finished the utility model finally.

The purpose of this utility model provides a kind of tire of structural development, particularly doing one at the packing structure in the tire changes, it mainly is that weighting material with the tool foaming property directly is fed in the tire, make the weighting material that serves as the inner tube of a tyre be able to and the complete driving fit of the tread of cover tire, tire is reached exempt from inflation, and non-slip between weighting material and tire, also can not be subjected to external force (as sharp object) and the situation that causes blowing out takes place.

Above-mentioned purpose of the present utility model realizes in the following manner: a kind of tire of structural development, comprise tire sleeve is located on the wheel rim, this wheel rim is provided with perfusion and chews, by irrigator weighting material is injected in the tire, be full of the space of tire and wheel rim after the weighting material foaming, and produce closely with the interior tread of tire and to combine.Described weighting material is optional from polyurethane (PU) or ethane-acetic acid ethyenyl based polyalcohol (EVA) or rubber, and the elasticity modulus of described weighting material is 10-30kg/mm.

The degree of depth of tread was 0.3-2mm in it was further characterized in that.

The utility model has the advantages that significantly: because the utility model system directly injects the weighting material of the tool foaming effect filling nozzle by wheel rim, make weighting material direct foaming in tire, the interior tread of this weighting material and tire will fit tightly fully at last.And tire is reached exempt from inflation, and can not skid between weighting material and tire, also can not be subjected to external force (as sharp object) and the situation that causes blowing out takes place.Therefore the utility model overcomes known shortcoming fully.

The utility model is described in further detail below with reference to drawings and Examples:

Fig. 1 is the utility model perspective exploded view.

Fig. 2 is the three-dimensional perfusion of a utility model scheme drawing.

Fig. 3 is a local structure cut-away view of the present utility model.

Consult Fig. 1, be perspective exploded view of the present utility model, as shown in the figure, a tire 1 is sheathed on the wheel rim 11, this wheel rim 11 is provided with a filling nozzle 111, takes turns frame 12 with one again and locks.

Consult Fig. 2 and Fig. 3, be three-dimensional perfusion scheme drawing of the present utility model and local structure cut-away view of the present utility model, as shown in the figure, one irrigator 2 is plugged on the filling nozzle 111 of wheel rim 11, and in the weighting material 3 injection tires 1 with a constant volume, because this weighting material 3 is a foaming substance, therefore this weighting material 3 will riddle in the space of tire 1 and wheel rim 11 after a period of time, and this weighting material 3 will produce closely with the interior tread 13 of tire 1 and combine this moment.

Wherein this weighting material 3 is a foaming substance, as polyurethane PU, ethane-acetic acid ethyenyl based polyalcohol EVA etc. or to can be as its elasticity moduluss such as rubber be the material of 10-30kg/mm.
