Abstract
The utility model relates to a radial tire which comprises a tread portion, a cap ply, tire shoulder portions, tire side-wall portions, a tire body portion, a tire rim, an inside liner portion and a bead ring. The tread portion is tightly connected with tire body portion through the cap ply, the tire shoulder portions are connected with end portions of the tread portion and the upper ends of the side-wall portions; and nylon reinforcement layers made of nylon cord fabric are paved on the lower portions of the tire shoulder portions. By means of the adoption of the radial tire, the tire is not easy to blast when a large loader and a large mining truck are in the process of goods transportation, and the service life of the tire is prolonged.
Description
Technical field:
The utility model relates to the tire field, particularly a kind of radial-ply tyre that can improve the uprising ability of tire shoulder.
Background technology:
Radial-ply tyre has very strong advantage than diagonal construction tire, and most large-duty loaders and large-scale mine transport trolley adopt radial-ply tyre.See also Fig. 1; Radial-ply tyre 10 of the prior art comprises: fetus face 11, sidewall portion 12, bracing ply 13, carcass portion 14, bead part 15, inside liner portion 16, tire shoulder portion 17, bead coil 18, though existing radial-ply tyre has at a high speed, comfortable, durable, safety, energy-saving advantages, the large-duty loader and the large-scale mine transport trolley that adopt radial-ply tyre are in transportation; The load capacity of radial-ply tyre is big; Rolling resistance is big, and turning is many, and the ordinary instant impact that receives; Break easily between fetus face and the sidewall portion, cause the phenomenon of blowing out.
Summary of the invention:
In view of this, be necessary to provide a kind of radial-ply tyre that can improve the uprising ability of tire shoulder.
One meridian line tyre comprises fetus face, bracing ply, tire shoulder portion, sidewall portion, carcass portion, bead part, inside liner portion, bead coil, and fetus face is through bracing ply and carcass portion leak-tight joint, and tire shoulder portion is connected with the end of fetus face, the upper end of sidewall portion; Tire shoulder subordinate side is equipped with the nylon strengthening course of processing with the nylon cord.
Preferably, the nylon strengthening course is laid between the carcass portion and inside liner portion of tire shoulder subordinate side.
Preferably, the nylon strengthening course comprises the first nylon carcass plies and the second nylon carcass plies, and the first nylon carcass plies and the second nylon carcass plies are laid between carcass portion and the inside liner portion in the same way.
Preferably, an end of nylon strengthening course extends to sidewall portion, and the other end of nylon strengthening course extends to fetus face.
Preferably, the width of nylon strengthening course is 280mm to 360mm, and the cord of nylon strengthening course and carcass portion angulation value range are that 50 degree are to 75 degree.
Large-duty loader and large-scale mine transport trolley owing to carry lot cargo, cause the load-bearing burden of tire when shipping goods; Especially under the bad situation of road conditions, when receiving instant impact, easily split easily by the junction of sidewall portion and fetus face for tire; Cause tire generation explosion, adopt the utility model, tire is when receiving bigger pressure and instant impact; The nylon strengthening course at tire shoulder portion place has stoped the distortion of tire, so, adopts the utility model; Large-duty loader and large-scale mine transport trolley tire when shipping goods is not easy explosion, has prolonged the service life of tire.
Description of drawings:
Fig. 1 is existing radial-ply tyre schematic cross-section.
Fig. 2 is the radial-ply tyre schematic cross-section of a preferred embodiments.
Among the figure: radial-ply tyre 10, fetus face 11, sidewall portion 12, bracing ply 13, carcass portion 14, bead part 15, inside liner portion 16, tire shoulder portion 17, bead coil 18, radial-ply tyre 20, fetus face 21, bracing ply 22, tire shoulder portion 23, sidewall portion 24, nylon strengthening course 25, carcass portion 26, bead part 27, inside liner portion 28, bead coil 29
The specific embodiment:
See also Fig. 2, the radial-ply tyre 20 that the utility model provides comprises fetus face 21, bracing ply 22, tire shoulder portion 23, sidewall portion 24, carcass portion 26, bead part 27, inside liner portion 28, bead coil 29.
The rubber layer that fetus face 21 finger wheel tires contact with the road surface; Fetus face 21 is through bracing ply 22 and carcass portion 26 leak-tight joints; The rubber layer that sidewall portion 24 refers between tire shoulder portion 23 lower ends and the bead part 27; Carcass portion 26 refers to that the single or multiple lift that constitutes tyre framework covers glue cord part, is provided with bead coil 29 in the bead part 27, and tire shoulder portion 23 is connected the end of fetus face 21 with the upper end of sidewall portion 24; Tire shoulder portion 23 belows are equipped with nylon strengthening course 25, and nylon strengthening course 25 is processed by the nylon cord.
In this embodiment, nylon strengthening course 25 is laid between the carcass portion 26 and inside liner portion 28 below the tire shoulder portion 23.Nylon strengthening course 25 comprises the first nylon carcass plies and the second nylon carcass plies, and the first nylon carcass plies and the second nylon carcass plies are laid between carcass portion 26 and the inside liner portion 28 in the same way.One end of nylon strengthening course 25 extends to sidewall portion 24, and the other end of nylon strengthening course 25 extends to fetus face 21.The width of nylon strengthening course 25 is 280mm to 360mm, and the cord of nylon strengthening course 25 and carcass portion 26 angulation value ranges are that 50 degree are to 75 degree.
Large-duty loader and large-scale mine transport trolley owing to carry lot cargo, cause the load-bearing burden of tire when shipping goods; Especially under the bad situation of road conditions, when receiving instant impact, with the junction of fetus face 21 easily split easily by sidewall portion 24 for tire; Cause tire generation explosion, adopt the utility model, tire is when receiving bigger pressure and instant impact; The nylon strengthening course 25 at tire shoulder portion 23 places has stoped the distortion of tire, so, adopts the utility model; Large-duty loader and large-scale mine transport trolley tire when shipping goods is not easy explosion, has prolonged the service life of tire.
