Problems solved by technology

There is also a split-type automobile tire with a replaceable tread and anti-puncture, but there are still deficiencies in the actual use process. One is that the tread has poor anti-puncture ability, large deformation, and poor rigidity; the other is that the tread is combined with the carcass. The two tooth grooves are parallel. With the prolongation of use time, it is easy to produce plastic deformation. When replacing the tread, it is difficult to achieve tight meshing, and even the phenomenon that the tread cannot be assembled; the third is that the anti-pinch sheet is Flat s

Example Embodiment

[0028] Example 1

[0029] see Figure 1-Figure 3 , Anti-puncture tire, including carcass 1 and tread 5 integrated with carcass 1, vulcanized three layers of belt layers in the tread 5, from the outside to the inside, the first layer is wound with steel wire in the direction of rotation of the tire The spiral belt layer 4 is formed, the helix angle of the spiral belt layer 4 changes with the tire diameter, the diameter of the steel wire, and the size of the steel wire interval. The second and third layers are the diagonally crossing belt layers 3 that cross each other; The angle α between the steel wire 301 in the bias belt 3 and the plane M where the tire rotation direction is located is 45°~75° (see image 3 ); The carcass 1 is vulcanized with the anti-puncture ring 2, which is composed of two anti-puncture sheets 201 staggered on different circles. The anti-puncture sheet 201 is like Figure 4 , Figure 5 As shown, there are several louver holes 2011 on the top, which are made ...

Example Embodiment

[0031] Example 2

[0032] see Image 6 The difference between this embodiment and implementation 1, is that the carcass 1 and tread 5 adopt teeth and grooves, and the carcass 1 and tread 5 adopt two symmetrical curved ring teeth 501a, 501b, and grooves; Such as Figure 7 As shown, the inner surface of the tread 5 is provided with two symmetrical curved ring teeth 501a, 501b, a number of reinforcing ribs 502 are provided between the two teeth, and the carcass 1 is provided with the curved ring teeth 501a and 501a on the tread 5. Curved annular groove corresponding to 501b; Figure 8 As shown, the carcass 1 can also be provided with curved annular teeth 101a, 101b, a number of reinforcing ribs 102 are arranged between the two teeth, and curved annular grooves are correspondingly arranged on the tread 5; the carcass 1 is provided with two intersecting layers The skew belt 3 is used to replace the anti-tie ring.

[0033] When the tire is inflated, the carcass 1 does not have the spira...

Example Embodiment

[0034] Example 3

[0035] see Picture 9 The carcass 1 and tread 5 of this embodiment adopt tooth and groove cooperation, and the rest are the same as the embodiment 1.

Abstract

The invention discloses an anti-pricking tire, comprising a tire body, a tire tread integrally vulcanized with the tire body, or a tire tread matched with teeth and grooves on the tire body, wherein belted layers are arranged in the tire tread; and at least one of the belted layers is a spiral belted layer wound by steel wires along the rotary direction of the tire. According to the anti-pricking tire disclosed by the invention, the anti-pricking performance can be improved, and the service life can be prolonged.

Description

technical field [0001] The invention belongs to automobile tires, in particular to an anti-puncture tire. Background technique [0002] The bias radial tires that existing automobiles use are integral structure tires, which are not resistant to punctures and are prone to tire bursts. There is also a split-type automobile tire with a replaceable tread and anti-puncture, but there are still deficiencies in the actual use process. One is that the tread has poor anti-puncture ability, large deformation, and poor rigidity; the other is that the tread is combined with the carcass. The two tooth grooves are parallel. With the prolongation of use time, it is easy to produce plastic deformation. When replacing the tread, it is difficult to achieve tight meshing, and even the phenomenon that the tread cannot be assembled; the third is that the anti-pinch sheet is The flat sheets are connected on the same circumference. When the tire is deformed by force, the anti-pinch pieces hinder ...
