Embodiment Construction

[0028] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Please refer to Figure 1-4 figure 1 It is a schematic diagram of the tread pattern of a pneumatic tire for automobiles provided by the embodiment of the present invention; figure 2 yes figure 1 Partial schematic diagram in ; image 3 yes figure 2 Middle Y-X section view; Figure 4 yes figure 2 Middle A-A sectional view.

[0030] Embodiments of the present invention provide a pneumatic tire for automobiles, such as figure 1 As shown, the tire includes a first main groove 1 and a second main groove 2 arranged along the circumferential direction of the tire, wherein the first main groove 1 is located on the outer side of the second main groove 2 (the side facing outwards in the tire use state) , the tire f...

Abstract

The invention relates to a pneumatic tire used for automobile. The pneumatic tire comprises a first main groove and a second main groove, a first row shoulder pattern is formed outside a first circumferential groove, and the first row shoulder pattern comprises a first shoulder transverse groove and three first fine grooves; the first shoulder transverse comprises a horizontal groove segment 1, ahorizontal groove segment 2, and a horizontal groove segment 3, wherein an included angle between the horizontal groove segment 1 and the horizontal groove segment 2 is 55-85 DEG, the included angle between the horizontal groove segment 2 and the first main grove is 5-45 DEG, the included angle between the horizontal groove segment 3 and the first main groove is 30-80 DEG, two first fine grooves are intersect with the first shoulder transverse groove, the first fine groove is parallel with the first shoulder transverse groove, so that the first row shoulder pattern can be separated several pattern blocks with circumferential staggered arrangement along a tire. The pneumatic tire can increase the shoulder intensity and bears instant impact force, abnormal abrasion appearance due to crimpinggenerated at groove edges can be avoided. and the noise generated at the tire surface during an automobile driving process can be reduced.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a pneumatic tire for automobiles. Background technique [0002] Nowadays, with the popularization of road improvement, the speed of cars changes more and more frequently, and when the car speeds up, brakes and turns in an instant, the speed changes greatly, which is reflected on the tires, and the instantaneous impact on the tread is large. Especially, the edge of the shoulder transverse groove is subjected to more significant impact force, which easily causes the edge of the shoulder transverse groove to be curled. [0003] Furthermore, reducing the noise generated by tires has always been the direction of efforts of various tire manufacturers when designing tires. [0004] Therefore, how to provide a pneumatic tire for automobiles, which can improve the strength of the tire shoulder, withstand the instantaneous impact force, avoid the appearance of abnormal wear caused by the cu...
