Description
Technical field
The utility model relates to a kind of pneumatic tire structure, refers to especially a kind of oblique pneumatic tyre body structure.
Background technology
In diagonal heavy truck tire carcass, can be provided with the cushion layer that strengthens tyre surface rigidity, the layer buffer design of existing diagonal tyre is and covers whole tyre surface, and its Main Function has the impact that relaxes road surface, strengthens tyre surface rigidity, strengthens the tear-resistant and thorn resistance energy of bottom of trench.If carcass cushion layer width exceedes whole tread width; can protect whole tire shoulder position; so; cushion layer can hold onto the radially growth of carcass, and tyre surface entirety radian is relatively large, if tire outline itself is too square; easily make tyre surface radian excessive; tyre surface to pass through performance influenced, whole tyre surface indent even, causes tire to occur early stage inordinate wear.
In addition; tire design first designs outline often; sometimes can find that tire makes its tyre surface radian inapplicable after finished product; if now remove cushion layer; the radially growth of tire becomes large, and the radian of tyre surface can diminish, but the protection of tire shoulder position reduces; tire shoulder position rigidity declines, and then affects the durability at tire shoulder position.
Utility model content
The purpose of this utility model is to provide a kind of oblique pneumatic tyre body structure, and it can solve the excessive problem that causes shoulder eccentric wear of tyre surface radian, can also strengthen the intensity of upper tyre bead, protection carcass.
For achieving the above object, solution of the present utility model is:
A kind of oblique pneumatic tyre body structure, this carcass comprises inner face glue, carcass layer and cushion layer, at carcass yarn inside, cushion layer covers on carcass layer inner face glue laminating; Carcass outside face forms tyre surface and tire shoulder; Wherein: cushion layer is to be symmetrical arranged as left and right separates taking tire section normal direction line of centers.
Described cushion layer is single or multiple lift setting.
Described adjacent buffer layer end points should stagger distance for more than 5mm.
Described cushion layer initial point to the angle that line and the tire section normal direction line of centers of tire section center-point form is arranged within the scope of 10 ° ~ 30 °.
The angle that the tire shoulder point of transition forming between described tyre surface and tire shoulder forms to the straight line of tire section center-point and the straight line of cushion layer initial point and tire section center-point is 8 ° ~ 28 °.
The angle that described cushion layer terminal forms to line and the tire section normal direction line of centers of tire section center-point is greater than the angle sum that angle that tire shoulder point of transition forms to the straight line of tire section center-point and the straight line of cushion layer initial point and tire section center-point and cushion layer initial point form to line and the tire section normal direction line of centers of tire section center-point.
Described cushion layer terminal to the angle that line and the tire section normal direction line of centers of tire section center-point form is set to 45 ° ~ 85 °.
The angle that the tire shoulder point of transition forming between described tyre surface and tire shoulder forms to the straight line of tire section center-point and the straight line of cushion layer terminal and tire section center-point is set to 15 ° ~ 50 °.
Adopt after such scheme, the tire shoulder portion of the utility model Pneumatic tire carcass is cushioned layer constraint, after tyre inflating, its tyre surface radius of the radian can effectively diminish, and the rigidity of tire shoulder portion and binding force can not reduce, can suppress the eccentric wear of tire shoulder, and upper tyre bead obtains reinforcement, strengthen the belt cutting-resisting property of carcass.
Brief description of the drawings
Fig. 1 is the utility model tire carcass schematic cross-section;
Fig. 2 is the partial enlarged drawing of Fig. 1.
Detailed description of the invention
Explain embodiment of the present utility model below in conjunction with accompanying drawing:
As shown in Figure 1, 2, the utility model has disclosed a kind of oblique pneumatic tyre body structure, and this carcass comprises inner face glue 1, carcass layer 2 and cushion layer 3.Inner face glue 1 is fitted in carcass layer 2 inside, and cushion layer 3 covers on carcass layer 2; Carcass outside face forms tyre surface and tire shoulder; Key of the present utility model is: cushion layer 3 is to separate and be symmetrical arranged taking tire section normal direction line of centers 8 as left and right, and cushion layer 3 can be single or multiple lift setting.
Coordinate shown in Fig. 2, while setting with multilayer, adjacent buffer layer 3,3 ' end points are the setting of staggering, and the distance A that staggers, B are more than 5mm.End points staggers apart from too little, easily causes in end point set, causes stress to be concentrated, easily separated.
Described cushion layer 3 initial point 31(with near tyre surface center for initial point definition) the angle θ that formed to line 6 and the tire section normal direction line of centers 8 of tire section center-point 4 is arranged within the scope of 10 ° ~ 30 °, can ensure the rigidity of tire shoulder portion, when if its angle θ is less than 10 ° cushion layer 3 from tyre surface center excessively close to, can not play the effect that reduces tyre surface radius of the radian, be difficult to suppress eccentric wear; If when angle θ is greater than 30 °, cushion layer 3 from tire shoulder close to, the initial point easy stressed generation in 31 places separates, thereby causes bulge.Coordinate shown in Fig. 1, the tire shoulder point of transition 51 forming between tyre surface and tire shoulder is 8 ° ~ 28 ° with cushion layer 3 initial points 31 with the angle beta that the straight line 6 of tire section center-point 4 forms to the straight line 5 of tire section center-point 4, under the angle limits of θ and β, make the distributing position of cushion layer initial point 31 more reasonable, thereby when making tire be difficult for producing bulge, suppress the eccentric wear of tire shoulder.
Described cushion layer terminal 32 to the line 7 of tire section center-point 4 is greater than above-mentioned angle beta and angle θ sum with the angle [alpha] that tire section normal direction line of centers 8 forms, and angle [alpha] is set to 45 ° ~ 85 °, above-mentioned angle [alpha] is less than 45 °, cushion layer 3 from tire shoulder close to, the terminal easy stressed generation in 32 places separates, thereby causes bulge; If be greater than 85 °, cushion layer terminal 32 is near the maximum disconnected wide place of tyre bead, and in traveling process, tyre bead distortion easily causes cushion layer terminal 32 to separate.Tire shoulder point of transition 51 is set to 15 ° ~ 50 ° with cushion layer terminal 32 with the angle γ that the straight line 7 of tire section center-point 4 forms to the straight line 5 of tire section center-point 4; be conducive to strengthen better the belt cutting-resisting property of upper tyre bead 9, thereby reach the effect of protection carcass.
To sum up, after tyre inflating of the present utility model, its tyre surface radius of the radian can effectively diminish, and the rigidity of tire shoulder portion and binding force can not reduce, and can suppress the eccentric wear of tire shoulder, and upper tyre bead 9 obtains reinforcement, the cutting property of enhancing carcass.
