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 sheets are connected on the same circumference. When the tire is deformed by force, the anti-pinch pieces hinder each other and reduce the elasticity. Long-term use is easy to separate the empty layer at the circumference surrounded by the anti-pinch pieces, which affects the service life of the tire.
At the same time, the layout of the above-mentioned structure has high requirements for the bonding between the anti-stripping sheet and the carcass rubber. When the tire is subject to alternating stress, it is easy to fatigue and separate, which also reduces the service life of the tire.

Embodiment 1

[0026] See Figure 1-Figure 3 , an anti-puncture tire, including a carcass 1 and a tread 5 vulcanized integrally with the carcass 1. Three layers of belt layers are vulcanized in the tread 5. From the outside to the inside, the first layer is formed by winding a steel wire along the direction of rotation of the tire. The spiral belt layer 4 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 layer and the third layer are diagonal belt layers 3 that cross each other; The included 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 ); anti-trap ring 2 is vulcanized in the carcass 1, and anti-trap ring 2 is made up of several anti-trap sheets 201 stacked on different circumferences by two circles, and anti-trap sheet 201 is as Figure 4 , Figure 5 As shown, there are several lou...

Embodiment 2

[0029] See Figure 6 , the difference between this embodiment and implementation 1 is that the carcass 1 and the tread 5 adopt teeth and grooves to cooperate, and the teeth and grooves of the carcass 1 and the tread 5 cooperate to adopt two symmetrical curved annular 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, and several reinforcing ribs 502 are arranged between the two teeth. The carcass 1 is provided with the curved ring teeth 501a, 501b corresponding to the curved ring groove; such as Figure 8 As shown, curved annular teeth 101a, 101b can also be set on the carcass 1, a number of reinforcing ribs 102 are arranged between the two teeth, and curved annular grooves are correspondingly arranged on the tread 5; .

[0030] When the tire is inflated, the carcass 1 has no helical belt layer 4 and expands in the radial direction, the curved annular teeth on the tread 5 ...

Abstract

The invention discloses an anti-pricking tire, which comprises a tire body and a tire surface. The tire surface is integrally vulcanized with the tire body, or the tire surface matches with teeth or a groove of the tire body, an anti-pricking ring is disposed in the tire body and consists of a plurality of anti-pricking plates divided into two circles, and the two circles of the anti-pricking plates are stacked on different circles in a staggered manner. The tire has the advantages that an anti-pricking performance can be improved, deformation is overcome, and the service life of the anti-pricking tire is 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 ...
