Abstract

The utility model discloses a tyre. The utility model comprises pattern blocks on a tyre tread, and a radiating groove on a tyre shoulder. The utility model is characterized in that tyre shoulders of the two adjacent pattern blocks extend to between the end points on the tyre sides and are provided with connecting ribs, and the thickness of the connecting rib is at least 1MM. The radiating grooves are positioned on the surface where the pattern blocks are on the tyre side, and the bottom parts are opened and transited to the tyre side surface; the side surfaces of the two adjacent radiating groove and the tyre side surface are in a circular arc transition surface or in a straight line shape transition surface; main troughs which are arranged between the pattern blocks can be properly broadened or deepened. The utility model increases the strength of the tyre shoulder, effectively overcomes the defect that the tyre shoulder is easy to be damaged when a vehicle passes through obstacles, and raises the radiating performance of the tyre shoulder; meanwhile, the aesthetic feeling effect of the tyre side of the tyre is added and the utility model can be used for various vehicles.

Description

A kind of tire

Technical field

The utility model relates to a kind of tire, the improved tire of particularly a kind of colored block structure.

Background technology

Existing domestic tire tire shoulder design shape is continued to use the shape that former Soviet Union expert recommends mostly, as shown in Figure 1, tire protector is provided with colored piece, the rectangular distribution piece of blossoming, between two adjacent colored pieces 1 is groove 4, on the colored piece surface on sidewall, be provided with the radiating groove 2 of closed groove shape, the root of flower piece 1 is separated from each other, this design shape is at road running or have to travel on the road surface of mating formation and have certain advantage, but in the environment that low-speed heave-load travels, when running into obstacle, the colored piece root that is separated from each other can be subjected to the effect of very big stress, under the independent stressed situation of flower piece root, tire shoulder is very easily fractureed, or cause the shoulder sizing material crackle of tire, and finally cause tire to come to nothing or take on emptyly, make tire lose value of service.

The utility model content

The purpose of this utility model is, overcome the above-mentioned defective of prior art, thereby a kind of tire is provided, by the new design of decorative pattern in the transition of tire shoulder position, increase the intensity of flower piece root so that tire can clear the jumps by safety and steady when low-speed heave-load, can effectively improve the heat radiation of tire tire shoulder simultaneously.

To achieve these goals, the utility model is realized by the following technical solutions.

A kind of tire that the utility model provides comprises: the colored piece on the tire protector, and the radiating groove of tire shoulder bottom, and the tire shoulder of described adjacent two colored pieces extends to the company's of being provided with muscle between the end points of sidewall, and this thickness that connects muscle is at least 1mm.Do not influencing under the tire shoulder heat-dissipation situation, the stress of colored piece root is disperseed,, making tire when breaking the barriers, reduce the impaired situation of tire shoulder to improve the intensity of flower piece root effectively.

As a kind of improvement of the present utility model, described radiating groove is positioned at colored piece on the surface, sidewall, and the bottom opening carries out the transition to the sidewall face, as further improvement, is the arc transition face between described radiating groove side and the sidewall face or is the linear pattern transition face.These two kinds of improvement have solved the heat dissipation problem of tire shoulder effectively, have increased the aesthetic effect of tire sidewall simultaneously again.

As of the present utility model another improve, the tap drain that forms between the described colored piece is can be suitably wideer or deepen or widen simultaneously intensification than conventional design.Because the design that connects muscle of the present utility model has strengthened the intensity of tire shoulder greatly, therefore, can not damage under the situation of tire shoulder, can further widen and deepen tap drain with the heat dissipation problem of better solution tire shoulder portion with save rubber.

Advantage of the present utility model is,

1, increases the intensity of colored piece root effectively, reduced the damage of tire shoulder.Owing to extend at the tire shoulder of two adjacent on the tyre surface colored pieces between the end points on sidewall and be provided with company's muscle that thickness is at least 1mm, changed the situation that the colored piece root of tire of the prior art meets with stresses separately, stress is reasonably disperseed, thereby improved the intensity of colored piece root, when tire when breaking the barriers, reduce the impaired situation of tire shoulder.

2, under the situation of the intensity that has strengthened colored piece, improved the heat radiation of tire shoulder, and increased the aesthetic effect of tire sidewall; The shape of radiating groove is by the poroid groove shape that the bottom is open into the sidewall face that changes into of the prior art, and can arc transition face or linear pattern transition face will be designed between the radiating groove side, because radiating groove is opening shape, solved tire shoulder Yin Shengre effectively and caused the problem of tire infantile failure.The tire that these improvement make the utility model provide has guaranteed the heat radiation of tire shoulder, has increased the aesthetic effect of tire sidewall again.

3, reduce traffic cost.Because the unique design of tire tire shoulder of the present utility model, make to have prolonged the in-use performance that tire can more effective performance tire under the usage condition of low-speed heave-load the service life of tire, thereby reduced traffic cost.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in detail;

As shown in Figure 2, a kind of tire is provided with colored piece 1 on tire protector, and the colored piece surface on sidewall is provided with radiating groove 2, extends to companys of being provided with muscle 3 between the end points at place, sidewall at the tire shoulder of two adjacent colored pieces 1, and the thickness of company's muscle is at least 1mm; Connect muscle owing to increased, changed the situation that the colored piece root of tire of the prior art meets with stresses separately, stress is reasonably disperseed, thereby has improved the intensity of colored piece root, when tire when crossing obstacle, groove 4 was stuck on the obstacle, connect muscle owing on tire, set up, the original root by a colored piece is met with stresses separately to become by two colored pieces bear simultaneously, make stress obtain rational dispersion, therefore, reduce the impaired situation of tire shoulder.

As shown in Figure 3, be an embodiment of the present utility model, in this example, between the tire shoulder of two adjacent colored pieces 1 extends to the end points at place, sidewall, added connect muscle 3 after, to be positioned at the lip-deep radiating groove 2 of colored piece on sidewall, be open into the sidewall face by the poroid bottom that is improved to of the prior art, this improvement makes the utility model when having strengthened colored piece root intensity, does not influence the heat radiation of tire shoulder.

As shown in Figure 4, be another embodiment of the present utility model, in this example, on the basis of a last embodiment, promptly after the bottom with radiating groove 2 is open into the sidewall face, to make the arc transition face between described radiating groove 2 sides and the sidewall face or be the linear pattern transition face, this improvement makes and guarantee that the heat radiation of tire shoulder is unaffected when increasing flower piece root intensity, increased the aesthetic effect of tire sidewall simultaneously again.

Claims
