Description

A kind of buffer layer structure of motorcycle tyre

Technical field

This utility model belongs to tire art, is related to a kind of improvement of cross ply tyre cushion and in particular to one kind is rubbed The buffer layer structure of motorcycle tire.

Background technology

Tire be various vehicles or mechanically assemble ground connection roll annular elastic rubber product.It is typically mounted on In alloy rim, vehicle body can be supported, buffer foreign impacts, realize the contact with road surface and ensure the driving performance of vehicle.Tire Often use under complexity and exacting terms, it subjects various modifications, load, power and high/low temperature effect in motion, because This must have higher load-carrying properties, hauling ability, shock-absorbing capacity.Meanwhile, also require possess high-wearing feature and flexible resistance, And low rolling resistance and heat generation.

Tire is divided into cross ply tyre, radial according to structure.Meridian tire and the fundamental difference of oblique line tire It is carcass.The carcass of oblique line tire is the casing ply that oblique line intersects；And the carcass of meridian tire is polymer multi-layer intersection material Matter, its top layer is the several layers of steel band cord weaved into by steel wire, can reduce the probability that tire is punctured by foreign body.

The tire being used for motorcycle is then cross ply tyre, is directed to traditional cross ply tyre structure technology and exists Run at high speed or air pressure is not enough, under the poor situation of pavement conditions, be easily subject to extraneous strong impaction that tyre cavity breach occurs, and Not impact resistance, thus reduce the service life of tire.

Utility model content

According to above the deficiencies in the prior art, this utility model provides cross ply tyre, by traditional cross ply tyre knot Structure design is adjusted, and uses for reference radial-ply tyre designing technique, and the body cord arrangement angle of tire is adjusted, rather than general One layer of logical cross-ply or two layers of body cord, to improve motility, durability and the comfortableness of tire.

A kind of buffer layer structure of motorcycle tyre described in the utility model it is characterised in that：Wrap successively from inside to outside Include inner face glue-line, second layer cord, third layer cord and the 4th layer of cord, wherein, the cord of described second layer cord is horizontal stroke To arrangement；The crown angle of the cord of described third layer cord and the 4th layer of cord is 48～55 degree, and third layer cord and the The cord-thread direction of four layers of cord is contrary.

Wherein, preferred version is as follows：

Described inner face glue-line is the sheet rubber of 1.5 millimeters of thickness.

The crown angle of the described cord of second layer cord is 0～10 degree.

Described third layer cord 3～5mm narrow compared to second layer cord, and it is covered in whole tyre surface.

Described the 4th layer of cord 3～5mm narrow compared to second layer cord, and it is covered in whole tyre surface.

In this utility model, inner side ground floor is inner face glue-line, using a kind of high elastic rubber piece of 1.5 millimeters thick, Even if poor in road conditions, tire strengthens shockproof effect in the case of running up, and more effectively avoids the inner tube of a tyre to damage, to bicyclist Bring more comfortable stable effect.Second layer cord is lateral arrangement is in 90 degree about brain clips angles with both sides wire loop, this layer Body cord design is with tyre crown width dimensions consistent, more effectively improves carcass strength, increase tire is in high speed, load-carrying In the case of safe buffering performance, reduce carcass ply between shear stress, make tire heat lower, improve tyre last, thus More robust, next guarantees tire, and size is more stable in the design process.The design of third layer cord and the 4th layer of cord with common The design of cross ply tyre is the same, and this two-layer is mainly responsible for providing the supportive of tire, even if vehicle boarded more, relatively In the case of the goods of weight, tire still can ensure that very high stability and good steering flexibility.

This utility model is had an advantageous effect in that：Have more with respect to traditional cross ply tyre and radial Plus superior performance, by changing tire construction, not only increase in terms of the whole intensity of tire and load-carrying, simultaneously in behaviour All lifted it is often more important that allowing the safer of consumer to trust in control motility, durability and comfortableness.

Brief description

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

In figure：1st, inner face glue-line 2, second layer cord 3, third layer cord 4, the 4th layer of cord.

Specific embodiment

Below in conjunction with drawings and Examples, this utility model is described further.

Embodiment 1：

As shown in figure 1, a kind of buffer layer structure of motorcycle tyre, include inner face glue-line 1, the second layer from inside to outside successively Cord 2, third layer cord 3 and the 4th layer of cord 4, wherein, the cord of described second layer cord 2 is lateral arrangement；Described The crown angle of the cord of third layer cord 3 and the 4th layer of cord 4 is 48～55 degree, and third layer cord 3 and the 4th layer of cord 4 Cord-thread direction is contrary.

Described inner face glue-line 1 is the sheet rubber of 1.5 millimeters of thickness.

The crown angle of the described cord of second layer cord 2 is 0～10 degree.

Described third layer cord 3 3～5mm narrow compared to second layer cord 2, and it is covered in whole tyre surface.

Described the 4th layer of cord 4 3～5mm narrow compared to second layer cord 2, and it is covered in whole tyre surface.

In the present embodiment, inner side ground floor is inner face glue-line 1, using a kind of high elastic rubber piece of 1.5 millimeters thick, that is, Make poor in road conditions, tire strengthens shockproof effect in the case of running up, more effectively avoid the inner tube of a tyre to damage, carry to bicyclist Carry out more comfortable stable effect.Second layer cord 2 is lateral arrangement is in 90 degree about brain clips angles with both sides wire loop, this layer of tire The design of body cord is consistent with tyre crown width dimensions, more effectively improves carcass strength, increases the feelings in high speed, load-carrying for the tire Safe buffering performance under condition, reduces shear stress between carcass ply, makes tire heat lower, improves tyre last, thus more Durable, next guarantees tire, and size is more stable in the design process.The design of third layer cord 3 and the 4th layer of cord 4 with common The design of cross ply tyre is the same, and this two-layer is mainly responsible for providing the supportive of tire, even if vehicle boarded more, relatively In the case of the goods of weight, tire still can ensure that very high stability and good steering flexibility.
