Abstract
The utility model provides a kind of novel tire support rubber die, including the support glue on the inside of carcass, the upper extreme point of the support glue is placed in the range of (0.72 0.86) * W1B, wherein W1B is the width of lower floor's belt half, the lower extreme point of the support glue and the distance of rim of the mouth shield glue lowermost end are 15 25mm, and the width L and the high SH of tire section of the support glue have the relation of 0.83≤L/SH≤0.91.The position of endpoint, makes its width be conducive to cover the larger region of stress above and below the utility model design support glue.
Description
Technical field
It the utility model is related to tyre technology, and in particular to a kind of novel tire supports rubber die.
Background technology
Run-flat tire is because it will not cause running out the way to cause security incident because of tire instantaneous loss of pressure at present；Tire is
Make in zero air pressure, the tire store that vehicle can still reach nearby changes tire.
Vehicle is due to that need not use spare tyre, the space bigger of boot.With good security, convenience, save sky
Intersexuality, run-flat tire has the good market space and development prospect, but due to the deficiency of support glue design, lacks at present
Gas guarantees tire under zero air pressure, and 60min can only be exercised with 80km/h.
Utility model content
The utility model provides a kind of novel tire support rubber die, can improve the mileage at the form of zero air pressure.
In order to solve the above technical problems, the utility model adopts the following technical solution：
A kind of novel tire supports rubber die, including the support glue on the inside of carcass, and the upper extreme point of the support glue is put
In the range of (0.72-0.86) * W1B, wherein W1B is the width of lower floor's belt half, the lower extreme point and son of the support glue
Mouthful shield glue lowermost end distance be 15-25mm, it is described support glue width L and the high SH of tire section with 0.83≤L/SH≤
0.91 relation.
2. novel tire according to claim 1 supports rubber die, it is characterised in that will be supported according to Temperature Distribution
The width of glue is divided into L from medium position to both sides1、L2、L3And L4, and L1：L2：L3：L4=1:0.64:0.53:0.53, it is described
The interior thickness for supporting glue is H1, L1And L2Point of intersection thickness be H2, L2And L3Point of intersection thickness be H3, L3And L4Intersection point
Place's thickness is H4, and H1：H2：H3：H4=1:0.91:0.7:0.42.
From above technical scheme, the utility model design supports the position of endpoint above and below glue, is conducive to its width
The larger region of stress is covered, while according to Tire support glue thickness and the linear relationship of temperature so that Tire support glue stress
Equilibrium, is conducive to be lifted endurance quality during zero air pressure of tire, can travel 100min with 80km/h, it is ensured that run-flat tire
Security performance.
Brief description of the drawings
Fig. 1 is the support rubber die figure of the utility model；
Fig. 2 is the layout drawing that the utility model supports glue.
Embodiment
A kind of preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.
The utility model run-flat tire is first bonded liner layer in shaping, fitting support glue after base drum opens, then
1P, 2P cord are bonded, detains wire loop, anti-package cord, is finally bonded sidewall.
In zero air pressure when driving, support glue temperature is very high for tire, shows tire sidewall position, and support glue stress is very big, this
Utility model is based on temperature field analysis, designs a kind of support rubber die, is conducive to be lifted zero air pressure endurance quality of tire.
As shown in Figure 1, in terms of tire running FEA analysis charts, whole 10 region of sidewall is stress large area, supports glue
20 are placed on the inside of sidewall, and support glue upper extreme point A is arranged in the range of (0.72-0.86) * W1B, and wherein W1B is lower floor's belt one
Half width, may be such that support glue upper extreme point covering stress large area.
The lower extreme point B of the support glue 20 and the distance of rim of the mouth shield glue lowermost end C are 15-25mm, be may be such that under support glue
Endpoint covers stress large area.The width L and the high SH of tire section of the support glue have the pass of 0.83≤L/SH≤0.91
System, SH is high for tire section, SH=tyre section width * Aspect Ratios.
As shown in Fig. 2, according to the Temperature Distribution of support glue, the width for supporting glue is divided into from medium position to both sides
L1、L2、L3And L4, and L1：L2：L3：L4=1:0.64:0.53:0.53, the interior thickness of the support glue is H1, L1And L2Friendship
Thickness is H at point2, L2And L3Point of intersection thickness be H3, L3And L4Point of intersection thickness be H4, and H1：H2：H3：H4=1:0.91:
0.7:0.42.It may be such that Tire support glue thickness and temperature line relationship so that Tire support glue stress equalization.
Embodiment described above is only that the preferred embodiment of the utility model is described, not to this practicality
New scope is defined, and on the premise of the spirit of the design of the utility model is not departed from, those of ordinary skill in the art are to this
The various modifications and improvement that the technical solution of utility model is made, should all fall into the guarantor that claims of the utility model determine
In the range of shield.
