Abstract
The invention relates to a tire belted layer structure which comprises at least two belted layers which are overlaid together. Edges of two adjacent belted layers form a step. The tire belted layer structure is characterized in that clamped rubber blocks are arranged between two belted layers at the step. Two side faces of each clamped rubber block are respectively adhered with two opposite faces of two adjacent belted layers. Each clamped rubber block is in a wedge or triangle shape. On the premise of not changing the structure of existing production equipment, the tire belted layer structure can solve the problem of air storing, deforming and the like at the edges of the belted layers, improves tire quality and prolongs service life.
Description
Technical field
The present invention relates to a kind of tire belt structure, especially a kind of tire belt structure that adopts belt rubber laminating.
Background technology
Existing wheeled car, particularly large-scale shipping load-carrying vehicle, they run quickly on express highway, should be fast again safely but also energy-conservation, these targets are had higher requirement to the tire of load-carrying vehicle.Wherein bracing ply plays an important role as the main stressed member of tire, and particularly tire belt structure reasonable in design can make tire have good mechanical property, also can increase the service life of tire when improving the tire quality.
Bracing ply refers under the tread base of radial-ply tyre and belted bias tire, along the material layer of circumferential line circumferencial direction banding carcass.It relaxes the impact except plaing a part, and mainly plays the banding carcass; For radial-ply tyre, its still main stressed member.
At present be bonded as stacking pattern (as shown in Figure 1) between the two-layer bracing ply of tire in each tire enterprise.But there is following defective in this kind form: one, so that belt speed layer limit section forms step, this type of step easily causes the part to deposit gas to each layer belt speed layer 1a in the tire production process, has a strong impact on the tire quality in additive process; Two, each layer belt speed layer 1a limit section is without more firm fixing, become in later stage sulfuration and easily to produce in the finished tire process because the flowing so that the situations such as displacement, distortion appear in belt speed layer limit section of sizing material, and these situations will directly affect mechanical property and the service life of finished tire.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of tire belt structure is provided, under the prerequisite that does not change the existing equipment structure, solve belt speed layer limit section and deposited the phenomenons such as gas, distortion, improve tire inspection qualification rate, quality, service life.
According to technical scheme provided by the invention, described tire belt structure, comprise the two-layer at least bracing ply that is superimposed, the limit section of adjacent bracing ply forms step, it is characterized in that: between two bracing plys at described step place the doubling piece is set, two sides of this doubling piece are bonding with two relative faces of adjacent bracing ply respectively.
Described doubling piece is wedge shape or triangle.
Tire belt structure of the present invention can solve belt speed layer limit section and deposit the phenomenons such as gas, distortion under the prerequisite that does not change the existing equipment structure, improves tire quality and service life.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete accompanying drawing.
As shown in Figure 2: described tire belt structure comprises bracing ply 1, doubling piece 2 etc.
As shown in Figure 2, the present invention includes the two-layer at least bracing ply 1 that is superimposed, the limit section of adjacent bracing ply 1 forms step, between two bracing plys 1 at this step place, doubling piece 2 is set, two sides of this doubling piece 2 are bonding with two relative faces of adjacent bracing ply 1 respectively, the problem of easily depositing gas to solve adjacent bracing ply 1 limit section, simultaneously so that bracing ply 1 limit section in conjunction with firm not yielding;
As shown in Figure 2, described doubling piece 2 is wedge shape or triangle, with sealing between relative two faces of two sides of realizing doubling piece 2 and adjacent bracing ply 1, reliable connection.
Tire belt structure of the present invention has adopted doubling piece 2 between adjacent two layers bracing ply 1, facts have proved, this form not only solves bracing ply 1 limit section and easily deposits the gas problem; Simultaneously so that bracing ply limit section, has solved fixing that each layer belt speed layer limit section can't be more firm in conjunction with firm not yielding, become in the finished tire process easily because the problems such as displacement, distortion appear in the mobile generation belt speed layer 1 limit section of sizing material in the later stage sulfuration.
Claims (2)
