Tyre with heat radiation slot formed on the tyre shoulder for automobile

Abstract

The invention aims to provide a tyre, particularly a tyre for vehicles for preventing abnormal wear of tyre tread by advancing the heat emission unit at the tyre shoulder of the tyre tread. In the previous tyre in driving, to emit heat of the edge, heat dissipation holes are formed on the tyre shoulder, or a unit such as a decoupling groove is formed, but the heat dissipation effect is not enough; in addition, the tyre has no function of preventing abnormal wear caused by interlocking of the tyre surface and tyre side. Therefore, in the invention, at the tyre shoulder departing from the edge,a groove is formed along the circumferencial direction, and the heat dissipation holes are installed inside the groove; heat dissipation grooves are respectively formed between the adjacent heat dissipation holes at the upper part of the tyre shoulder and the lower part of the groove, thereby being capable of enhancing the heat dissipation effect and preventing normal wear of tyre surface by separating the interlocking of tyre surface and tyre side.

Description

technical field [0001] The present invention relates to a tire, in particular to an automobile tire capable of reducing abnormal wear of the tread by improving the formation of a heat dissipation unit at the shoulder connected to the tread. Background technique [0002] The tread of a tire for automobiles is provided with a multi-layer belt, for example, as observed image 3 In the conventional tire shown, the plurality of belt layers (104) provided at the inner bottom of the tread (101) disperse the shear stress by varying the positions of the ends. Among them, the second belt (104a) And the end of the third belt (104b) extends to the vicinity of the shoulder (109) side, and the end of the belt (104) moves actively during tire running, and generates a lot of heat in particular. [0003] That is, since the thickness of the shoulder (109) connecting the tread (101) and the sidewall (102) is thick, the tire produced by the second belt (104a) and the third belt (104b) is quickl...

[0003] That is, since the thickness of the shoulder (109) connecting the tread (101) and the sidewall (102) is thick, the tire produced by the second belt (104a) and the third belt (104b) is quickly released to the outside. The heat of the tread (101) is limited, and the above-mentioned tread (101) will increase the probability of abnormal wear due to the movement of the couple (Couple) that changes in conjunction with the sidewall (102).

[0004] On the other hand, conventionally, in order to dissipate the heat generated from the above-mentioned shoulder (109), a method such as Figure 4 In the shown tire, heat dissipation holes (110) are formed on the shoulders (109) connecting the tread (101) and the sidewall (102), or decoupling grooves (Decoupling Groove) are formed, so that the The heat transmitted from the end of the tire radiates to the outside through the shoulder (109). However, in such a heat dissipation structure, the heat dissipation effect of the shoulder is not sufficient. In addition, the tread (101) and the sidewall (102) cannot be effectively separated. ), thus lacking the function of preventing the above-mentioned abnormal wear of the tread (101)
