Description

A kind of novel tire

Technical field

The utility model relates to tyre technology, especially a kind of novel tire.

Background technology

The freight house vehicle using in factory, the bearing truck that hand barrow etc. travel is at a slow speed because of its work under bad environment, therefore its tire generally uses foaming wheel or tubeless tires, existing foaming wheel because of be by tire injection foaming be formed on wheel rim, be combined with wheel rim firm not, in use be prone to separation, the problem such as come off is accidents caused, the wheel rim that existing tubeless tires uses is all (as shown in Figure 1) of umbilicate type, tire is connected in the depressed area of wheel rim, the problem so existing is that the loading strength of wheel rim is less, so in order to guarantee the loading strength of tire entirety and the size of tire entirety, need rim size less, tire size is larger, tire part consumptive material leak tightness and resistance to deformation large and to tire are had relatively high expectations.

Utility model content

The utility model is intended to address the above problem, a kind of novel tire is provided, its tire is combined the problem such as be not firmly in use prone to separation, come off with wheel rim, use safety, can stream time long, bearing capacity is large, long service life, can save easily-consumed products tire with material, cost-saving, obtained certain beneficial effect, its technical scheme adopting is as follows:

A kind of novel tire, comprise: tire, wheel rim, spoke and wheel shaft, described wheel rim and spoke are one-body molded, described spoke connects wheel rim and wheel shaft, described wheel rim is made up of revolver rim and right wheel rim, described revolver rim is identical with right wheel rim shape and be symmetrical set, the left and right sides outwardly convex of described wheel rim forms annular stopper section, the circumferential edge of described revolver rim forms left half Access Division towards the direction protuberance of axle axis dorsad, the circumferential edge of described right wheel rim forms right half Access Division towards the direction protuberance of axle axis dorsad, the right hand edge of described left half Access Division forms Access Division together with being welded in the left hand edge of right half Access Division jointly, the left surface of left stopper section is greater than the width of Access Division to the distance of the right flank of right stopper section, described tire sleeve is connected on Access Division.

On technique scheme basis, described wheel shaft is fabricated from iron.

On technique scheme basis, in the centre hole of described wheel shaft, be coated with bearing, described bearing and centre hole are interference fit.

On technique scheme basis, described tire material adopts polyurethane.

On technique scheme basis, the arcwall face that the lateral surface of described spoke is outwardly convex.

On technique scheme basis, described bearing is radial bearing.

On technique scheme basis, the tire toe bottom of described tire is butted on stopper section.

The utlity model has following advantage: the material of using that can save tire approximately 20%, save replacement cost, the foaming tire long service life that the bearing truck travelling at a slow speed compared with freight house vehicle, hand barrow etc. uses at present, tyre and rim is easily separated coming off not, use safety, large 2 to 3 times than the loading strength of common foaming tire of loading strengths, can stream time length grow 3 to 4 times than common foaming tire, more laborsaving while promoting bearing truck.

Nomenclature:

1. tire, 2. wheel rim, 3. spoke, 4. wheel shaft, 5. Access Division, 6. stopper section, 7. bearing, 20. revolver rims, 21. right wheel rims, 22. left half Access Divisions, 23. right half Access Divisions.

The specific embodiment

Below in conjunction with accompanying drawing and example, the utility model is described in further detail:

As shown in Figures 2 to 5, a kind of novel tire, comprise: tire 1, wheel rim 2, spoke 3 and wheel shaft 4, described wheel rim 2 and spoke 3 are one-body molded, described spoke 3 connects wheel rim 2 and wheel shaft 4, described wheel rim 2 is made up of revolver rim 20 and right wheel rim 21, described revolver rim 20 is identical with right wheel rim 21 shapes and be symmetrical set, the left and right sides outwardly convex of described wheel rim 2 forms annular stopper section 6, the circumferential edge of described revolver rim 20 forms left half Access Division 22 towards the direction protuberance of wheel shaft 3 axis dorsad, the circumferential edge of described right wheel rim 21 forms right half Access Division 23 towards the direction protuberance of wheel shaft 3 axis dorsad, the right hand edge of described left half Access Division 22 forms Access Division 5 together with being welded in the left hand edge of right half Access Division 23 jointly, the left surface of left stopper section is greater than the width of Access Division 5 to the distance of the right flank of right stopper section, described tire 1 is socketed on Access Division 5, Access Division 5 both can make tire 1 firm with wheel rim 2 combinations, can improve again the loading strength of wheel rim 2, that so the size of wheel rim 2 can be done is larger, it is less that tire 1 portion size does, can save the material of tire 1, because tire 1 belongs to easily-consumed products, wheel rim 2 is conventionally not fragile, therefore this kind of structure of wheel rim 2 can be saved the cost of changing of tire 1, this kind of structural bearing intensity of wheel rim 2 is large, can stream time long, more laborsaving while promoting bearing truck.

Preferably, described wheel shaft 3 is fabricated from iron, and the tire that existing bearing truck uses adopts plastics wheel shaft easy to wear substantially.

Preferably, be coated with bearing 7 in the centre hole of described wheel shaft 3, described bearing 7 is interference fit with centre hole.

Preferably, described tire 1 material adopts polyurethane.

Preferably, the arcwall face that the lateral surface of described spoke 3 is outwardly convex, can increase loading strength.

Further, described bearing 7 is radial bearing, because this tire is mainly used on bearing truck, therefore select the radial bearing such as carbon bearing as dark in anti-package cheaply.

Further again, the tire toe bottom of described tire 1 is butted on stopper section 6.

With way of example, the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
