Abstract

The objective of the present invention is to provide tires for heavy vehicles in long-distance driving. The invention is characterized by having two decoupling grooves vertically arranged on the side of the tire shoulder, and increasing the width of decoupling grooves with a projected part formed between two decoupling grooves, so that the upper side of the tire shoulder can be prevented from being coupled with the lower side even with a heavy load to avoid the worry about the insertion of foreign bodies like stones into decoupling grooves.

Description

Tire for heavy vehicle
Technical field
The present invention relates to be used for the tire of the heavy-duty vehicle of long distance travel, the eccentric wear that particularly relates in order to suppress tire shoulder portion decreases, and is provided with the tire for heavy vehicle of decoupling groove (Decoupling Groove) in tire shoulder portion.
Background technology
Shown in Fig. 1 (A), be installed on heavyly with in the tire in the past of vehicle, by the grounding parts place in the tire shoulder portion 102 of joining with tyre surface 101 eccentric wear that decoupling groove 103 prevents tire shoulder portion 102 is set and decreases.
Yet; but there is following shortcoming in this tire; promptly through regular meeting chap in the bottom of decoupling groove 103 (Crack); when this be full of cracks extends to the edge of bracing ply and can cause the bracing ply accident, perhaps it extends to sidewall portion and causes the shortcoming that comes off as the protrusion 105 of sacrificing fin.
Therefore, shown in Fig. 1 (B), come off, a kind of tire that the height of protrusion 105 is reduced greatly is provided in order not make as the protrusion 105 of sacrificing fin.
Yet but there is following shortcoming in this tire, promptly, the area of tyre surface 101 is reduced, and its result causes the area of contact between tire and the road surface to reduce, and has dwindled the width of tyre surface, shorten wear-out life, therefore had to stand the low worries of performances such as minimizing of tyre surface traction and braking force.
In addition, in tire in the past, following a kind of like this tire was also proposed, shown in Fig. 1 (C), the sidewall of tire shoulder portion 102 is provided with decoupling groove 103, remove the worry that abrasion loss and be full of cracks are taken place by removing as the protrusion of sacrificing fin, yet, but there is following shortcoming in tire with this structure, promptly under steam tire is loaded under the situation of big load, the position up and down of the inlet portion of decoupling groove 103 contacts with each other, thereby causes decoupling groove 103 can't bring into play its function.And on the other hand, if make the inlet portion of above-mentioned decoupling groove 103 excessively open formation, then probably can occur sandwiching situation in the decoupling groove as foreign matters such as stones, therefore do not wish to enlarge the size of the inlet portion of decoupling groove 103.
Summary of the invention
Therefore, the object of the invention is to provide a kind of tire for heavy vehicle, its decoupling groove shape that will be arranged at tire shoulder portion sidewall becomes 2 up and down, by between 2 decoupling grooves, forming the width that protrusion increases the decoupling groove, even if load very big load like this, can not make the contact of position up and down of tire shoulder portion yet, simultaneously, prevent that also foreign matters such as stone from sandwiching the situation in the decoupling groove.
Description of drawings
Fig. 1 is the part sectional view of tire for heavy vehicle tire shoulder portion in the past.
Fig. 2 is the part sectional view of pith that is tire shoulder portion in the embodiments of the present invention.
Fig. 3 is the part sectional view of pith that is tire shoulder portion in the another embodiment of the invention.
The specific embodiment
Below, with the present invention will be described in conjunction with the accompanying drawings.
The present invention is a kind of tire for heavy vehicle, comprise tyre surface 1, sidewall portion (not shown) and bead part (not shown), tire shoulder portion at tyre surface 1 is formed with the decoupling groove, and be that the sidewall that this decoupling groove shape is formed in tire shoulder portion 2 is formed, it is characterized in that, above-mentioned decoupling groove is formed at the sidewall of tire shoulder portion 2 in the mode of 2 decoupling grooves 3,4 up and down, and is being formed with protrusion 5 between 2 decoupling grooves 3,4 up and down.
When the sidewall in above-mentioned tire shoulder portion forms up and down 2 decoupling grooves 3,4, the size of decoupling groove 3,4 up and down can be formed same size, also can increase the size of upside decoupling groove 3 as shown in Figure 2, dwindle the size of downside decoupling groove 4, perhaps as shown in Figure 3, dwindle upside decoupling groove 4, increase downside decoupling groove 3.
Here, preferably, form the generation that circle suppresses to chap with bottom with 2 decoupling grooves 3,4.
The present invention of Gou Chenging has following effect thus, promptly when the suffered load of such in the past tyre surface when sidewall portion one side is transmitted, make its bump disperse to be alleviated by the decoupling groove, particularly, by 2 decoupling grooves 3,4 are set, therefore even also can overcome following shortcoming being loaded with under the situation of big load, promptly join mutually between the inlet portion because of the decoupling groove, and make the decoupling groove can not bring into play the shortcoming of due effect.
