Abstract
The invention discloses an all-steel light-weight load radial tire. The all-steel light-weight load radial tire comprises a tread part, tire sidewalls, a tire bead part, a cord fabric layer and a belted layer, and is characterized in that the belted layer comprises a belted layer No.1, a belted layer No.2, a belted layer No.3 and a belted layer No.4, the belted layer is designed in a variable-angle manner, the width of the belted layer No.4 is narrow, and one belted layer is matched with one layer of viscosifying and reinforcing film. The rigidness of a crown part of the tire is increased, when the tire is in running, the circumferential deformation is reduced, the tire is stable to run, and the rolling resistance is effectively reduced; the puncture resistance in a harsh multi-rock environment is greatly improved, and when the tire is punctured in a rainy season, a tire body can be effectively prevented from being rusted by the rainy water by virtue of the viscosifying and reinforcing film with a waterproof function, the service life can be prolonged by 1 to 3 times, the rolling resistance of the tire can be reduced by 28 percent, oil can be saved by 6 to 6.5 percent since the tire is environment-friendly, and not only can environmental protection and energy conservation be achieved, but also the running cost can be reduced.
Description
Technical field
The present invention relates to a kind of tire, relate to a kind of all-steel light radial truck tire specifically.
Background technology
The all-steel light radial truck tire that current domestic many tire enterprise extensively adopt, as shown in Figure 1, comprise fetus face 1, sidewall 2, bead part, carcass plies 3, bracing ply 4, bracing ply 4 is made up of 3 layers of bracing ply, i.e. 1# bracing ply, 2# bracing ply, 3# bracing ply.All-steel light radial truck tire field of application is more and more wider, tire rolling resistance in operational process is large, automobile fuel consumption is high, and energy-saving effect is poor, simultaneously under the usage condition that stone pit etc. is severe during operation, wheel crown part is very easily wounded by stabbing, serious is even quick-fried by thorn, and a lot of tire enterprise, by deepening decorative pattern, changing pattern pitch, is improved the methods such as tread glue formula and reduced tire drag, improve the anti-puncture performance of tire, have certain effect.But tire drag is still comparatively large, and during raining working, tire is wounded by stabbing, and carcass is subject to rainwater corrosion, and as repaired not in time, tire will be scrapped or blow out.
Summary of the invention
Problem to be solved by this invention is the deficiency overcoming above-mentioned technology, provides one to have low-rolling-resistance, waterproof, anti-puncture belt structure all-steel light radial truck tire.
Technical scheme of the present invention is:
A kind of all-steel light radial truck tire, comprise fetus face, sidewall, bead part, carcass plies, bracing ply, it is characterized in that: described bracing ply comprises 1# bracing ply, 2# bracing ply, 3# bracing ply, 4# bracing ply, described bracing ply adopts varied angle design, is provided with the thickening of water-proof function, strengthens film between described 3# bracing ply and 2# bracing ply.
Between described 1# bracing ply, 2# bracing ply, 3# bracing ply, 4# bracing ply each layer bracing ply, cord is crossed as netted mutually, and the angle of described belt cord and crown line of centers is less than 90 °.
The cord of described 1# bracing ply and the angle of crown face line of centers are 22 °, the cord of 2# bracing ply and the angle of crown face line of centers are 27 °, the cord of 3# bracing ply and the angle of crown face line of centers are 20 °, and the cord of 4# bracing ply and the angle of crown face line of centers are 16 °.
Described thickening, strengthen width 4mm ~ 16mm that the width of film is greater than 2# bracing ply, thickening, the thickness that strengthens film is 2mm-4mm.
Described 4# belt width is less than the 4mm ~ 12mm of 3# belt width.
The cord of described 1# bracing ply, 2# bracing ply, 3# bracing ply is high tenacity steel cord, and 4# belt cord is high drawing steel cord.
The invention has the beneficial effects as follows:
The present invention adopts varied angle design due to bracing ply, and 4# belt width is narrow, uses one deck bracing ply and one deck thickening, strengthens film, and the bizet rigidity of tire increases, and in motion, circumferential modification reduces tire, and smooth ride, rolling resistance effectively reduce; Significantly improve in the anti-puncture performance of many rock environment of harshness; when operation in rainy season; tire is wounded by stabbing; there is the thickening of water-proof function, strengthen film meeting actv. protection carcass from rainwater corrosion; extend 1 ~ 3 times service life; tire drag reduces 28%(green tire), fuel-economizing 6%-6.5%, both environmental protection and energy saving again reduced operating cost.
