Abstract
The invention relates to a tire tread extrusion-molding structure applicable to mixed road conditions. The tire tread extrusion-molding structure comprises a tire tread rubber part and a tire tread base rubber part, and is characterized in that the tire tread rubber part and the tire tread base rubber part are in arch transition at a tire tread shoulder part. The tire tread extrusion-molding structure is simple and reasonable; by improvement on the distribution forms of rubber at the tire tread shoulder part, the enough thickness of pattern grooves in a tire tread is ensured, the tire tread is wear-resistant, the heat of the tire tread shoulder part is reduced, the heat radiating effect of the tire tread shoulder part is enhanced, the early damage to a tire is alleviated, the requirements on the overall performance of the tire are satisfied and the service life of the tire is prolonged greatly.
Description
Technical field
The present invention relates to the improvement of tire protector removing from mould structure, specifically a kind of tire protector removing from mould structure that is applicable to mix road conditions.
Background technology
Tire, as the load bearing component of vehicle, plays very important effect, and particularly, for card passenger car load tire, it should bear whole loads, also will ensure the personnel's of riding safety.This has just proposed extra high performance requriements to tire.In tire design, production process, especially to catch two main key points: the one, the each glue component of tire must reach designing requirement, and the 2nd, select suitable tyre framework structure and material.And in the first key point, most important in the various glue components of tire is exactly tyre surface, the removing from mould structure of tyre surface is generally main to be made up of tread-rubber part 1 and tread slab base part 2, tread-rubber part 1 has the feature of high abrasion, promotion heat, and tread slab base part 2 has low-heat-generation, not wear-resisting feature.At present, each tire enterprise mainly contains two kinds for the design of tyre surface removing from mould structure:
1, tread-rubber part 1 all contacts with tread slab base part 2, belongs to full somatotype (shown in Fig. 1, Fig. 2).
2, in contact both sides, centre does not contact tread-rubber part 1 with 2 of tread slab base parts, belongs to shoulder somatotype (shown in Fig. 3, Fig. 4).
Can find out from Fig. 1 ~ Fig. 4, the tyre surface removing from mould structure of above two kinds of forms, tread-rubber part 1 is all to take trapezoidal transition with tread slab base part 2 at tyre surface shoulder 3, its size transition is comparatively even, but the tread-rubber of tyre surface shoulder 3 is thicker, it is also larger that its tread-rubber part 1 in the process of travelling rises heat at tyre surface shoulder 3 places, cannot shed in time; And due to tire in the process of moving each position and road surface stressed be inhomogeneous, and then cause every place to rise heat also inconsistent, this will make identical material thickness, the effect of the heat producing in different positions and heat radiation is inconsistent, especially easily occur that the 3 center temperature rises of tyre surface shoulder are too high, cause the sizing material of tire protector shoulder 3 to damage under high-temperature condition, occur the early stage problems such as shoulder sky, greatly shortened Using Life of Tyre.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of tire protector removing from mould structure that is applicable to mix road conditions is provided, its structure design advantages of simple, improve by the glue distribution form to tyre surface shoulder, not only can ensure has enough thickness at the bottom of the groove on tyre surface, and make tyre surface more wear-resisting, reduce tyre surface shoulder heat-dissipating, improve tyre surface shoulder radiating effect, reduce the earlier period damage of tire, ensure the requirement of tire overall performance, greatly extended the service life of tire.
According to technical scheme provided by the invention: be applicable to mix the tire protector removing from mould structure of road conditions, comprise tread-rubber part and tread slab base part, it is characterized in that: described tread-rubber part and tread slab base part adopt arch transition at tyre surface shoulder.
As a further improvement on the present invention, the vertex of the tread slab base part of described arch intermediate location after sulfuration is higher than groove bottom.
As a further improvement on the present invention, the vertex thickness of the tread slab base part of described arch intermediate location after sulfuration is 1/2 ~ 3/4 of tyre surface shoulder gross thickness.
As a further improvement on the present invention, the vertex thickness of the tread slab base part of described arch intermediate location after sulfuration is 2/3 of tyre surface shoulder gross thickness.
the present invention compared with prior art, has the following advantages:the present invention improves by the glue distribution form to tyre surface shoulder, change tread-rubber part and tread slab base part into arch transition at tyre surface shoulder by trapezoidal transition, not only can ensure has enough thickness at the bottom of the groove on tyre surface, and make tyre surface more wear-resisting, reduce tyre surface shoulder heat-dissipating, improved tyre surface shoulder radiating effect, reduced the earlier period damage of tire, ensure the requirement of tire overall performance, greatly extended the service life of tire.Through evidence, this tyre surface removing from mould structure can improve tire Combination property more than 25%, and endurance quality improves approximately 10%, can be applicable to better mix the vehicle travelling in road conditions.

Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 5, Figure 6, the tire protector removing from mould structure that is applicable to mix road conditions of the present invention mainly comprises tread-rubber part 1 and tread slab base part 2, and described tread-rubber part 1 adopts arch transition with tread slab base part 2 at tyre surface shoulder 3.
As shown in Figure 5, Figure 6, in the embodiment of the present invention, the vertex a of the tread slab base part 2 of described arch intermediate location after sulfuration is higher than groove 4 bottom b.In general, the vertex a thickness h of the tread slab base part 2 of described arch intermediate location after sulfuration is 1/2 ~ 3/4 of tyre surface shoulder 3 gross thickness H.Preferably, the vertex a thickness h of the tread slab base part 2 of arch intermediate location after sulfuration is 2/3 of tyre surface shoulder 3 gross thickness H.
