Abstract

The invention discloses an off-the-road tyre capable of improving the radiating condition in the middle of tread. The off-the-road tyre comprises a groove in the tread. The groove is a radiating groove formed in the middle of the tread. The number of the radiating groove is one, two or more. The radiating groove is a square groove. The depth of the square groove is 1/4-3/5 of the depth of a tread pattern groove. The width of the square groove is 4%-6% of the width of the tread. According to the off-the-road tyre, the radiating groove is formed in the middle of the tread, radiating performance in the region is improved, and meanwhile abrasion resistance and puncture resistance of the tread can not be lowered.

Description

Can improve the off-the-road tyre of tyre surface heat radiation condition in middle

(1) technical field:

The present invention relates to a kind of off-the-road tyre, specifically a kind of off-the-road tyre that improves the tyre surface heat radiation condition in middle.

(2) background technology:

Rim diameter is 49 " and above earthwork stone purposes off-the-road tyre; have multilayer carcass oblique configuration; this type tire in use; tyre surface central region center give birth to heat apparently higher than tire shoulder and other each section part; find through measuring, under equal conditions, the temperature at center, crown middle part reaches 100 ℃~103 ℃; the temperature at tire shoulder this moment center is no more than 100 ℃, and this phenomenon is deepening to show more obviously on decorative pattern and super deep tread patterns off-the-road tyre.

The crown middle part is constantly given birth to heat and is dispelled the heat bad, to aggravate the Tire Composites hydraulic performance decline, early stage cause thermal damage and cause tyre failure is in order to fall low-heat-generation, sometimes have to cut away whole tyre surface, such way can cause the not wear-resisting and easy stabbing bundle of off-the-road tyre.

(3) summary of the invention:

The invention provides a kind of off-the-road tyre that improves the tyre surface heat radiation condition in middle.

The technical scheme that the present invention can improve the off-the-road tyre of tyre surface heat radiation condition in middle comprises the groove that is opened on tyre surface, and difference is the radiating groove of described groove for offering on circumference in the middle part of tyre surface, and described radiating groove is one or two or more pieces.The temperature that the tire that described radiating groove can make operation produces in the tyre surface middle part was dispelled the heat but not originally only have from tyre surface from the tyre surface internal heat dissipating, had greatly improved the radiating effect at tyre surface middle part.

Described radiating groove can be set to any shape in theory, but square groove is the most practical the simplest radiating groove.

In the situation that offer a square radiating groove, for self-cleaning, load and the paracentesis resistance of taking into account off-the-road tyre and have the actv. radiating effect, the degree of depth of this radiating groove is the degree of depth of 1/4~3/5 tread contour, and the width of this radiating groove is the width of 4%~6% tyre surface.

Advantage of the present invention:

The off-the-road tyre that the present invention can improve the tyre surface heat radiation condition in middle is at the tyre surface middle part, a radiating groove to be set, increased should the zone heat dispersion, do not reduce resistance to abrasion and the anti-puncture performance of tyre surface simultaneously yet.

(4) description of drawings:

Fig. 1 is the structural representation of one embodiment of the present invention.

Figure number sign: 1, tyre surface; 2, radiating groove; 3, tread void; 4, carcass.

(5) specific embodiment:

Below in conjunction with accompanying drawing, technical scheme of the present invention is described further:

Figure 1 shows that the present invention can improve the local carcass 4 of the off-the-road tyre of tyre surface heat radiation condition in middle, the face that carcass 4 contacts with ground is tyre surface 1, the both sides, middle part of described tyre surface 1 are the tread void 3 that the position is symmetrical or misplace, and offering a square trench on the circumference at tyre surface 1 middle part, described square trench is radiating groove 2.

The width w of described radiating groove 2 is 4%~6% of tyre surface 1 width W, and the degree of depth h of described radiating groove 2 is 1/4~3/5 of tread void 3 depth H, as shown in Figure 1.

Claims (3)

1. can improve the off-the-road tyre of tyre surface heat radiation condition in middle, comprise the groove that is opened on tyre surface (1), it is characterized in that: the radiating groove (2) of described groove for offering on circumference in the middle part of tyre surface (1), described radiating groove (2) is one or two or more pieces.
2. the off-the-road tyre that improves the tyre surface heat radiation condition in middle according to claim 1, it is characterized in that: described radiating groove (2) is square groove.
3. the off-the-road tyre that improves the tyre surface heat radiation condition in middle according to claim 2, it is characterized in that: described radiating groove (2) is one, the degree of depth of this radiating groove (2) is the degree of depth of 1/4~3/5 tread void (3), and the width of this radiating groove (2) is the width of 4%~6% tyre surface (1).
