Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to an all-steel radial tire. Background Art

[0002] A radial tire is a pneumatic tire in which the carcass cords are arranged at an angle of 90° or close to 90° to the centerline of the crown, and the carcass is tightened by the belt layer. Radial tires are divided into full steel radial tires, semi-steel radial tires and full fiber radial tires.

[0003] According to the related prior art, the carcass of the all-steel radial tire includes a carcass steel wire layer and a wire ring. The two ends of the carcass steel wire layer form a wrapping bag, and the wire ring is arranged in the wrapping bag to improve the strength of the tire mouth.

[0004] However, when the road surface becomes more bumpy, the strength of the rim is weakened. If the vehicle continues to drive in this way, the rim will gradually crack or become hollow. Utility Model Content

[0005] Based on the above description, the utility model provides an all-steel radial tire, aiming to solve the problem that the existing all-steel radial tire has weakened strength at the tire mouth when encountering a more bumpy road surface.

[0006] The technical solution of the utility model to solve the above technical problems is as follows:

[0007] An all-steel radial tire, comprising:

[0008] Carcass;

[0009] A carcass steel wire layer is disposed in the carcass, and both ends of the carcass steel wire layer form wrapping bags;

[0010] A wire ring is arranged in the wrapping bag;

[0011] A reinforcing cloth layer, wrapped in the wrapping bag;

[0012] At least one nylon wrapping layer is wrapped around the reinforcing wrapping layer.

[0013] On the basis of the above technical solution, the present invention can also be improved as follows.

[0014] Furthermore, the reinforcing cloth layer is steel wire or iron block.

[0015] Furthermore, the carcass has a crown region, and the crown region is provided with a first belt layer, a second belt layer, a third belt layer and a fourth belt layer in sequence toward the carcass steel wire layer.

[0016] Further, the length of the second belt layer is the same as that of the first belt layer.

[0017] Further, the third belt layer is longer than the first belt layer, the second belt layer and the fourth belt layer.

[0018] Furthermore, the carcass comprises a shoulder region, and the shoulder region is provided with a first buffer layer and a reinforcement layer in sequence toward the carcass steel wire layer.

[0019] Furthermore, the first buffer layer is made of elastic metal material.

[0020] Furthermore, the reinforcement layer is made of metal.

[0021] Furthermore, a second buffer layer is provided between the carcass steel wire layer and the reinforcement layer.

[0022] Furthermore, the second buffer layer is made of rubber or plastic.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0024] (1) The present invention greatly increases the stability and strength of the tire by reinforcing the covering layer, thereby improving the quality of the tire and making the fatigue resistance better. The overall profile deformation of the tire is reduced when resisting load, thereby extending the service life of the tire.

[0025] (2) Through the cooperation of the first buffer layer and the reinforcement layer, when the shoulder area is subjected to impact force, the first buffer layer first buffers the impact force; the reinforcement layer, on the one hand, blocks the first buffer layer from further deformation, and on the other hand, strengthens the strength of the shoulder area, thereby reducing the impact of the impact force on the shoulder area.

[0026] (3) The second buffer layer of the present application isolates the carcass steel wire layer from the reinforcement layer to prevent the reinforcement layer from wearing the carcass steel wire layer when the tire shoulder area is subjected to impact force. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] It will be appreciated that spatial relationship terms such as "under," "beneath," "below," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be appreciated that, in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "above" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.
