Abstract
The invention relates to a tire crown structure, comprising a tread. The tire crown structure is characterized in that the lower side of the tread is orderly provided with a bottom rubber sheet and a cloth liner, wherein the cloth liner is a plastic spacer; the tread, the bottom rubber sheet and the cloth liner shrink towards a centre line in sequence to form gradient; and 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 tread. With the tire crown structure provided by the invention, the problem of crimping and water accumulation of the sides of the tread can be solved under the premise of keeping original structure of the existing production equipment, and the inspection qualified rate of tires can be improved.
Description
Technical field
The present invention 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 objective of the invention is to overcome the deficiency that exists in the prior art, a kind of tyre crown structure is provided, do not change under the prerequisite of existing equipment structure, solve tyre surface limit portion crimping nest water phenomenon, improve the tire inspection qualification rate.
According to technical scheme provided by the invention, 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.
Tyre crown structure of the present invention 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 a structural representation of the present invention.
The specific embodiment
Below in conjunction with concrete accompanying drawing the present invention is described further.
As shown in the figure: the tyre crown structure comprises tyre surface 1, primer sheet 2, shield 3 etc.
The present invention includes the tyre surface 1 of tyre crown, set gradually primer sheet 2 and shield 3 at the downside of tyre surface 1, 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 tyre crown of the present invention 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.Advantage of the present invention is: 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.
