Abstract

The utility model relates to a tire crown structure which comprises a tire tread. The tire crown structure is characterized in that the lower side of the tire tread is sequentially provided with a bottom rubber sheet and a cloth liner, wherein the cloth liner is a plastic gasket; the tire tread, the bottom rubber sheet and the cloth liner sequentially contract towards the direction of a centre line so as to form gradient; the width of the cloth liner is less than that of the bottom rubber sheet; and the width of the bottom rubber sheet is less than that of the tire tread. On the premise of not changing the structure of the existing production equipment, the tire crown structure solves the problems of curling and water accumulation of the edge of the tire tread, thus improving the pass rate of check of a tire.

Description

The tyre crown structure
Technical field
The utility model relates to a kind of structure of tyre crown, especially a kind of crown structure that adopts shrinkage type primer sheet.
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.The key point of tire mainly contains two parts: at first being the crown of tire, secondly is that the cage construction and the material of tire selected for use.Crown particularly, crown reasonable in design can make the adhesion value of tire protector improve, and play the high efficiency hauling operation that Duola hurries up.Vehicle is wanted to adapt to the hauling operation on the express highway, tire protector is had higher requirement, so it should have suitable friction force that suitable friction drag is arranged again.
At present tire protector and bracing ply bonding generally is divided into following type in each tire enterprise: the whole applying primer sheets in (1) tyre surface bottom; (2) the tyre surface bottom primer sheet of not fitting adopts additive method to guarantee the tyre surface bottom adhesive, for example adopts the form of spraying rubber cement.But there is defective in above form: one, all fit the primer sheet in use tyre surface limit portion be prone to the nest water phenomenon of curling, in the later stage use, be prone to cause finished product tire shoulder portion to go wrong; Two, the form of spraying rubber cement to environmental requirement, later stage deposit, operating needs is higher.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art, and a kind of tyre crown structure is provided, and does not change under the prerequisite of existing equipment structure, solves tyre surface limit portion crimping nest water phenomenon, improves the tire inspection qualification rate.
According to the technical scheme that the utility model provides, said tyre crown structure comprises tyre surface, and characteristic is: the downside at said tyre surface sets gradually primer sheet and shield.
Said shield is the plastics shield.
Said tyre surface, primer sheet, shield shrink to centerline direction successively and form gradient.
The width of said shield is less than the width of primer sheet, and the width of said primer sheet is less than the width of tyre surface.
The described tyre crown structure of the utility model can solve tyre surface limit portion crimping nest water phenomenon under the prerequisite that does not change the existing equipment structure, improve the tire inspection qualification rate.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with concrete accompanying drawing the utility model is described further.
As shown in the figure: the tyre crown structure comprises tyre surface 1, primer sheet 2, shield 3 etc.
The utility model comprises the tyre surface 1 of tyre crown, sets gradually primer sheet 2 and shield 3 at the downside of tyre surface 1, and said shield 3 is the plastics shield;
Said tyre surface 1, primer sheet 2, shield 3 shrink to centerline direction successively and form gradient, with the staged setting; The width of said shield 3 is less than the width of primer sheet 2, and the width of said primer sheet 2 is less than the width of tyre surface 1.
The tyre surface of the described tyre crown of the utility model adopts shrink form; Make tyre surface overall with, primer sheet, plastics shield form stepped gradient; Facts have proved that this form not only solves the use amount that existing tyre surface limit portion nest water problems improves crown quality, tire quality reduction sizing material, plastics shield simultaneously.The utility model has the advantages that: adopt shrinkage type tyre surface primer to solve tyre surface limit portion on the one hand and be prone to nest water phenomenon; Improved the tyre surface quality; Improve the qualification rate of tire; Not only do not change existing processes flow process or Fabricating machinery through improving on the other hand, also reduced the consumption of bottom sizing and tyre surface shield.
