Description

Non-pneumatic tire for SUV {NON-PNEUMATIC TIRE FOR SUV}

The present invention relates to a non-pneumatic tire for SUV, and more particularly, to a non-pneumatic tire for SUV that can significantly reduce the possibility of a large accident due to puncture.

In general, tires such as various vehicles, agricultural equipment, bicycles, bogies, and wagons are classified into radial tires, bias tires, and solid tires according to the structure. Among them, most of the cars except for passenger cars and special purposes have radial tires, that is, pneumatic pressure. Tires are used. The pneumatic tires are designed to absorb the impact from the road surface while supporting the load of the vehicle using the pressure of the air filled in the tires.

When such a pneumatic tire is damaged by an external shock while driving, the air pressure suddenly decreases, so there is a problem in that the vehicle cannot be controlled and an accident occurs. In order to demonstrate the performance of the pneumatic tire, the air pressure must be checked frequently. The pneumatic tire has a complicated structure, and also has a manufacturing problem in that the number of manufacturing processes is high in multiple stages, resulting in a large amount of harmful substances.

As an alternative to solving the above-described problems of the pneumatic tire, a non-pneumatic tire has been developed that can elastically support a vehicle without using pneumatic pressure, and most of the non-pneumatic tires maintain the shape of the existing pneumatic tire. , It is an elastic support placed between the rim and the tread to support the load of the vehicle and absorb shock from the road surface. Unlike pneumatic tires, these non-pneumatic tires can significantly reduce production costs through simplification of materials and processes, as well as significantly reduce energy and harmful substances in production. Unlike pneumatic tires, they do not use compressed air at all. Therefore, it has the advantage of being free from the risk of accidents that may occur during driving due to loss or lack of air pressure.

As a prior art for such a non-pneumatic tire, in Korean Patent Registration No. 10-1450475, it is arranged in a circumference of a tire wheel and is formed in a donut shape surrounding the circumference of the tire wheel. It has a first side wall portion disposed around the circumference, a second side wall portion disposed around the second rim of the tire wheel, and a skeleton portion connecting an outer diameter portion of the first side wall portion and an outer diameter portion of the second side wall portion. Rubber body; A spoke layer having a plurality of ring-shaped spokes coupled around the skeleton portion of the rubber body; A tread cap coupled to the spoke layer and surrounding the spoke layer; And an inner diameter portion and a second side wall of the first side wall portion to press the first side wall portion toward the first rim and compress it to the first rim, and at the same time press the second side wall portion toward the second rim and compress the second side wall portion. Containing; a plurality of rim support assembly that is coupled to the inner diameter of the portion at the same time, the rim support assembly is coupled to the inner diameter portion of the first side wall portion of the first rim support contacting the first rim of the tire wheel, one end A second rim support coupled to the inner diameter of the second side wall portion and in contact with the second rim of the tire wheel, wherein the first rim support and the second rim support are pivotally coupled to their intermediate portions by pivot axes, The first rim support is elastically deformed so that the other end of the first rim support is fixed to the second rim support and at the same time the second rim support is elastically deformed so that the other end of the second rim support is fixed to the first rim support, so that the first A non-pneumatic tire has been disclosed, characterized in that one end of the first rim support is pressed toward the first rim of the tire wheel and at the same time one end of the second rim support is pressed toward the second rim of the tire wheel.

However, the prior art is composed of many components, and the overall structure is very complicated, and thus there is a problem in that production and sales costs are greatly increased.

The problems to be solved by the present invention are as follows.

First, it reduces the possibility of a major accident due to puncture while driving the vehicle.

Second, it is to reduce the amount of rubber used.

Third, it improves fuel efficiency compared to existing tires.

The problems of the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the following description.

In order to achieve the above object, a non-pneumatic tire for SUV according to an embodiment of the present invention, the cylindrical tread portion in contact with the ground; Vehicle wheels; A urethane spoke fixed to the wheel and absorbing the impact of the tread portion; And a carbon ring inserted into the tread portion to prevent distortion of the tread portion.

In addition, a non-pneumatic tire for SUV according to another embodiment of the present invention, the cylindrical tread portion in contact with the ground; Vehicle wheels; A urethane spoke fixed to the vehicle wheel and absorbing the impact of the tread portion; And a carbon ring disposed between the urethane spoke and the tread portion.

Specific details of other embodiments are included in the detailed description and drawings.

According to the present invention has the following effects.

First, it is possible to reduce the possibility of a large accident due to puncture while driving the vehicle.

Second, the amount of rubber used can be reduced.

Third, fuel efficiency can be improved compared to conventional tires.
