Description

Motorcycle pneumatic tire

Technical field

This utility model relates to motorcycle pneumatic tire, particularly relates to a kind of tread contour and carcass structure changes The tire entered.

Background technology

Along with the performance requirement of motorcycle is increasingly paid attention to by consumer, to the requirement of tyre performance also More and more higher, for the tire of the general streamlined decorative pattern of motorcycle and conventional carcass structure design, When tire is pierced through by foreign object, the easy flat gas of tire, it is impossible to travel to maintenace point, bring puzzlement to consumer. For improving carcass sidewall intensity, often changed carcass the design of into multilamellar carcass structure by one layer of carcass structure, To improve carcass sidewall rigidity so that when tire is pierced through by foreign object, still can support vehicle load, continue row Sail a segment distance.But being arranged such, its tyre surface rigidity is too high, when beating the most easily occurs in tire, Comfort property is the best.Therefore, it is necessary to study a traveling demand that can ensure when tire is pierced again The novel tire of tire ride comfort energy can be improved.

Utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, it is provided that one can ensure wheel Traveling demand when tire is pierced can improve again the motorcycle pneumatic tire of tire ride comfort energy.

For achieving the above object, this utility model is by the following technical solutions:

Motorcycle pneumatic tire, including tyre surface, tire shoulder, carcass, sidewall, tire lip and bead core, described Carcass is made up of one layer of belt, two-layer casing ply and one layer of internal surface layer, and it presses close to the of described belt One layer of casing ply and press close to the second layer casing ply of described internal surface layer and be wound to sidewall along bead core, described The end of one layer of casing ply is coated in the tail end of described belt, and wrapped position is arranged at tire shoulder, institute Stating and be provided with one layer of hard rubber layers between second layer casing ply and internal surface layer, described hard rubber layers is two Hold the form of thin thick middle across tyre surface and sidewall area.

Preferably, described hard rubber layers leans on the front end of tyre surface radial distance between tire diameter baseline For the 75%-85% of tire section height, it leans on the rear end on sidewall radial distance between tire diameter baseline 20%-30% for tire section height.

Preferably, the thickest region of described hard rubber layers is arranged on the intersection of tire shoulder and sidewall.

Preferably, described bead core is provided with hard triangle rubber, its away from the front end of bead core away from tire Radial distance between internal diameter baseline is the 25%-35% of tire section height.

Preferably, described tyre surface is made up of with decorative pattern counter drain group decorative pattern tap drain, described decorative pattern tap drain and decorative pattern The tail end of counter drain group is provided with bottom of trench and builds bridge.

Preferably, the 10%-20% that axial length is tread width that described bottom of trench is built bridge.

Preferably, the height that described bottom of trench is built bridge is the 50%-80% of corresponding groove depth.

After using technique scheme, this utility model, compared with background technology, has the advantage that

1, arrange bottom of trench at each groove near the position of tire shoulder to build bridge, not only increase tread contour rigidity, Improve the intensity of tire shoulder, prevent tire to be punctured the generation of rear tyre flat gas phenomenon；

2, optimizing carcass design, the hard rubber layers adding two ends thin thick middle form makes tyre surface Thickness from tyre surface center by thin gradually thicker than crossing, improve comfortableness, and its thickest region be arranged on tire shoulder and The intersection on sidewall, and on bead core, add hard triangle rubber, thus improve the intensity on sidewall, Play the effect supporting vehicle load, it is achieved explosion prevention function, travelled by the continuation after puncturing meeting tire Demand.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with attached Figure and embodiment, be further elaborated to this utility model.Should be appreciated that described herein Specific embodiment, only in order to explain this utility model, is not used to limit this utility model.

Embodiment

As it is shown in figure 1, motorcycle pneumatic tire, including tyre surface 1, carcass 2, tire shoulder 3, sidewall 4, Tire lip 5 and bead core 6.

Wherein, carcass 2 includes one layer of belt 21, two-layer casing ply 22,23 and the most successively Layer internal surface layer 24.Press close to the ground floor casing ply 22 of belt 21 and press close to the second layer curtain of internal surface layer 24 Layer of cloth 23 is wound to sidewall 4 along bead core, and the end B of ground floor casing ply 21 is coated on belt 21 Tail end in, wrapped position is arranged at tire shoulder 3.Between second layer casing ply 23 and internal surface layer 24 Being additionally provided with one layer of hard rubber layers 25, the sizing material hardness of hard rubber layers 25 is 65-75JIS-A, its In two ends, the form of thin thick middle is across tyre surface 1 and region, sidewall 4.

Definition hard rubber layers 25 is front end near one end of tyre surface 1, is rear end near the one end on sidewall 4. Its front end 75%-85% that radial distance H2 is tire section height H1 between tire diameter baseline C； Its rear end 20%-30% that radial distance H3 is tire section height H1 between tire diameter baseline C. The thickest region of hard rubber layers is arranged on the intersection of tire shoulder 3 and sidewall 4.It is arranged such, then hard The thinnest front-end and back-end of rubber layer 25 respectively close to tyre surface 1 center and the center on sidewall 4, Ensure that the thickness of tyre surface 1, by thin gradually thick change, has relaxed tyre surface rigidity so that tire is difficult to beat, Ensure that the comfortableness rided；The thickest region is arranged on tire shoulder 3 and the intersection on sidewall 4, improves Tyre surface 1 and the intensity on sidewall 4, when tire is pierced through by foreign object, remain to support vehicle load, continue row Sail a segment distance.

Being additionally provided with hard triangle rubber 7 on bead core 6, defining it away from one end of bead core 6 is front end, Its front end 25%-35% that radial distance H4 is tire section height H1 between tire diameter baseline C, Further increase the rigidity on sidewall 4, support vehicle load, improve operating range.

It addition, be also carried out optimizing design, as in figure 2 it is shown, tyre surface 1 is by spending to the pattern structure of tyre surface 1 Stricture of vagina tap drain 11 forms with decorative pattern counter drain group, and decorative pattern counter drain group includes counter drain 12 and counter drain 13.Decorative pattern tap drain It is provided with bottom of trench bridge formation 14 with the tail end of decorative pattern counter drain group.As shown in Figures 2 and 3, bottom of trench bridge formation 14 The 10%-20% that axial length L 1 is tread width L, highly H6 be corresponding groove depth H5 50%-80%.It is arranged such, it is ensured that the ability of tyre surface 1 one's water breaks film, and is effectively increased at tire shoulder 3 The rigidity of decorative pattern, improves the intensity of tire shoulder 3, it is to avoid when groove bottom is pierced through by foreign object, causes tire Flat gas.

The above, only this utility model preferably detailed description of the invention, but protection of the present utility model Scope is not limited thereto, the skill that any those familiar with the art discloses at this utility model In the range of art, the change that can readily occur in or replacement, all should contain protection domain of the present utility model it In.Therefore, protection domain of the present utility model should be as the criterion with scope of the claims.
