Description

Oblique Pneumatic tire carcass structure

Technical field

The utility model is related to pneumatic tire technical field, particularly relates to a kind of oblique Pneumatic tire carcass structure.

Background technology

In order to relax the impact on road surface, strengthen rigid, enhancing bottom of trench the tear-resistant and thorn resistance energy of tyre surface, oblique wheel Cushion can be set in tire carcass, as shown in figure 1, the cushion 2 ' of existing cross-ply carcass structure may be contained within carcass Between curtain yarn 3 ' and tread rubber 1 ', i.e., curtain yarn 3 ' is first pasted when green tire is molded, then paste cushion 2 ', finally paste tread rubber 1 '.So The carcass structure of design, the end points of cushion 2 ' is directly contacted with tread rubber 1 ', so that cross-ply is in load-carrying, low wind Under pressure, the use condition of high speed, the tread rubber 1 ' at tire shoulder can be deformed in flexion repeatedly with cushion 2 ', because of the deformation of cushion 2 ' Degree produces tread rubber 1 ' at the two-end-point for the cushion 2 ' being easily caused at tire shoulder not as good as the sizing material deformation extent of tread rubber 1 ' Sizing material separated with carcass, or be produce tire shoulder bulge phenomenon, cause the early damage of tire, there is potential safety hazard.

Utility model content

The purpose of this utility model is to provide a kind of oblique Pneumatic tire carcass structure, and it can not increase cost, work The problem of tread rubber is separated with cushion is solved while the performance for ensureing tire on the premise of sequence, the use of tire is improved Life-span.

Based on this, the utility model mainly uses following technical proposal, to realize above-mentioned purpose.

A kind of oblique Pneumatic tire carcass structure, including：Tread rubber, the cushion below the tread rubber, curtain yarn Layer, steel wire, are provided with least one layer of curtain yarn layer between the tread rubber and the cushion, the curtain yarn layer coats the buffering Layer simultaneously rolls up setting on steel wire.

The cushion is more than one layer.

Further, it is arranged at intervals between each cushion by least one layer of curtain yarn layer.

Further, the radial distance that the joint between each cushion staggers is 5mm ~ 10mm.

After adopting the above technical scheme, the utility model is arranged at tread rubber and cushion by least one layer of curtain yarn layer Between, cushion is coated on the carcass Optimal Structure Designing of internal layer by curtain yarn layer, isolation cushion and tread rubber it is direct Contact, so that avoid the end points of cushion and tread rubber from subduing generation stress concentration repeatedly, and the curtain yarn layer is rolled up on steel wire Set, ensure on the premise of further avoiding the segregation phenomenon of cushion, realization not to increase cost, process under the constraint of steel wire The problem of tread rubber is separated with cushion is solved while the performance of tire, the purpose of the service life of tire is improved.

Embodiment

Embodiment of the present utility model is explained below in conjunction with accompanying drawing：

In order to preferably describe the utility model, make defined below first：Vertical direction is tire radial direction, and horizontal direction is Tire axial.

As shown in Fig. 2 the utility model discloses a kind of oblique Pneumatic tire carcass structure, including tread rubber 1, curtain yarn layer 3rd, cushion 2, steel wire 4, at least one layer of curtain yarn layer 3 are arranged between tread rubber 1 and cushion 2, and curtain yarn layer 3 is by cushion 2 Internal layer is coated on, isolation cushion 2 is directly contacted with tread rubber 1, so as to avoid the end points and tread rubber 1 of cushion 2 repeatedly Flexion produces stress concentration, and curtain yarn layer 3 rolls up setting on steel wire 4, and cushion 2 is further avoided under the constraint of steel wire 4 Segregation phenomenon.

Furthermore, the number of plies of cushion 2 can be one layer（As shown in Figure 2）Or multilayer.

For example, cushion 2 is 2 layers, respectively first buffer layer 21, second buffer layer 22, as shown in figure 3, this reality With new disclosed oblique Pneumatic tire carcass structure, tread rubber 1, the first curtain yarn layer 31, first buffering are followed successively by from top to bottom Layer 21, second buffer layer 22, the second curtain yarn layer 32, steel wire 4, wherein first buffer layer 21, second buffer layer 22 are adjacent, and at least one The curtain yarn layer 3 of layer is arranged between tread rubber 1 and first buffer layer 21, and the cushion 2 of multilayer can strengthen carcass intensity, Simultaneous buffering performance is more preferably, it is noted that, the joint of first buffer layer 21 and second buffer layer 22 staggers, the footpath preferably staggered To being 5 ~ 10mm apart from L1, so as to avoid the stress concentration of joint, and curtain yarn layer 3 rolls up setting on steel wire 4, in steel wire 4 Cushion is further avoided to separate and cause the destruction of tire under constraint.

In addition, it can be adjacent bed that the cushion 2 of multilayer, which is set,（As shown in Figure 3）, can also be spaced and be coated on curtain yarn layer 3 It is interior.

For example, cushion 2 is 2 layers, respectively first buffer layer 21, second buffer layer 22, as shown in figure 4, this reality With new disclosed oblique Pneumatic tire carcass structure, tread rubber 1, the first curtain yarn layer 31, first buffering are followed successively by from top to bottom The 21, second curtain yarn layer 32 of layer, second buffer layer 22, steel wire 4, first buffer layer 21 are spaced at least one layer of curtain yarn with tread rubber 1 Layer 31 is set, and first buffer layer 21 is spaced at least one layer of curtain yarn layer 32 with second buffer layer 22 and sets, first buffer layer 21 and The joint of second buffer layer 22 staggers, and the radial distance L2 preferably staggered is 5 ~ 10mm, so that the stress concentration of joint is avoided, and And first curtain yarn layer 31, the second curtain yarn layer 32 roll up setting on steel wire 4, cushion is avoided to separate and lead under the constraint of steel wire 4 Cause the destruction of tire.

In summary, the utility model is arranged between tread rubber 1 and cushion 2 by least one layer of curtain yarn layer 3, curtain Cushion 2 is coated on internal layer by yarn layer 3, and the curtain yarn layer 3 rolls up the carcass Optimal Structure Designing of setting, institute on steel wire 4 The number of plies for stating cushion 2 can be 1 layer or multilayer, and cushion 2 can be adjacent bed, can also be spaced and be coated on curtain yarn The internal layer of layer 3, isolation cushion 2 is directly contacted with tread rubber 1, so as to avoid the end points of cushion 2 and tread rubber 1 from bending repeatedly Generation stress concentration is scratched, the segregation phenomenon of cushion 2 is further avoided under the constraint of steel wire 4.

The utility model is in molding procedure except cushion 2 and curtain yarn layer 3 stick the order and prior art of preparative layer cylinder There is remaining unusual process consistent with prior art, so that on the premise of cost and process is not increased, it is ensured that the usability of tire The problem of tread rubber is separated with cushion is solved while energy, the service life of tire, simple to operate, high efficiency is improved.

It is described above, only it is preferred embodiment of the present utility model, not technical scope of the present utility model is made Any limitation, therefore the change or modification done in every case according to claim of the present utility model and specification, should all belong to this practicality Within the scope of new patent is covered.
