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 cage construction and the material selection of tire.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 wants 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.
Tire protector and the bonding of bracing ply generally are divided into Types Below in each tire enterprise at present: (1) tyre surface bottom is applying primer sheet all; (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 section be prone to curling nest water phenomenon, in the later stage use procedure, easily cause finished product tire shoulder section 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 deficiencies in the prior art, a kind of tire crown structure is provided, do not change under the prerequisite of existing equipment structure, solve tyre surface limit section crimping nest water phenomenon, improve the tire inspection qualification rate.
According to technical scheme provided by the invention, described tire crown structure comprises tyre surface, and feature is: the downside at described tyre surface sets gradually primer sheet and shield.
Described shield is the plastics shield.
Described tyre surface, primer sheet, shield shrink to centerline direction successively and form gradient.
The width of described shield is less than the width of primer sheet, and the width of described primer sheet is less than the width of tyre surface.
Tire crown structure of the present invention can solve tyre surface limit section 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 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 the figure: tire 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, described shield 3 is the plastics shield;
Described tyre surface 1, primer sheet 2, shield 3 shrink to centerline direction successively and form gradient, with the staged setting; The width of described shield 3 is less than the width of primer sheet 2, and the width of described 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, so that 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 section 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 on the one hand tyre surface limit section and be prone to nest water phenomenon, improved the tyre surface quality, improve the qualification rate of tire, not only do not change existing technological process or Fabricating machinery by improving on the other hand, also reduced the consumption of bottom sizing and tyre surface shield.
Claims (2)
