Problems solved by technology

At present, there is a split-type automobile tire with replaceable tread and anti-puncture, but there are still deficiencies in the actual use process. First, the tread has poor anti-puncture ability, large deformation, and poor rigidity; second, the combination of the tread and 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 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

[0029] See Figure 1-Figure 3 , processing-free anti-puncture recycling tires, 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 made of steel wire along the tire The spiral belt layer 4 is wound in the direction of rotation. 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 belts that cross each other. Belt layer 3; the angle α between the steel wire 301 in the bias belt layer 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...

Embodiment 2

[0032] See Image 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; The diagonal belt layer 3 is used to replace the anti-piercing ring.

[0033] When the tire is inflated, the carcass 1 has no helical belt layer 4 and expands...

Embodiment 3

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

Abstract

The invention discloses a machining-free puncture-resisting recycled tire, comprising a carcass and a tread integrated with the carcass in vulcanization or a tread matched with carcass teeth and grooves, wherein a belt layer is arranged in the tread. The recycled tire is characterized in that a puncture-resisting ring or a belt layer is arranged in the carcass; and at least one of the belt layers in the carcass is a spiral belt layer formed by winding steel wires around the rotation direction of the tire. According to the invention, the tire can improve the puncture-resisting performance, overcomes deformation and extend the service life.

Description

technical field [0001] The invention belongs to automobile tires, in particular to a processing-free, puncture-resistant, recyclable tire. Background technique [0002] The bias radial tires used in existing automobiles are tires with an integral structure, which are not resistant to punctures, are prone to puncture, and must be replaced as a whole after the tread is worn or the carcass is punctured, resulting in waste of resources and environmental pollution. The refurbishment method is recycled, and its recycling rate is only 7% in our country. About 15% in developed countries, and the cost of recycling is very high. At present, there is a split-type automobile tire with replaceable tread and anti-puncture, but there are still deficiencies in the actual use process. First, the tread has poor anti-puncture ability, large deformation, and poor rigidity; second, the combination of the tread and the carcass The two tooth grooves are parallel. With the prolongation of use tim...
