Description

  The present invention relates to a tire used for a vehicle or the like.

  Generally, a tire used for a vehicle or the like includes a resin tire main body and a tire wheel provided along the inner periphery of the tire main body. The tire wheel is provided with a rim that engages with the tire body, and an air chamber is formed between the outer peripheral surface of the rim and the inner peripheral surface of the tire body.

  Here, conventionally, the air chamber constitutes one annular space along the circumferential direction of the tire body, and a predetermined air pressure is applied to the inside thereof. For this reason, if the tire body is damaged even at one location, the internal air escapes from the location, and the predetermined air pressure initially applied over the entire tire cannot be maintained. Therefore, a vehicle or the like equipped with such a tire has a problem that it is impossible to maintain safe traveling due to damage at one place of the tire body.

  The present invention has been made in view of these points, and an object of the present invention is to provide a tire that can maintain a safe running of a vehicle or the like even if the tire body is damaged at least in one place. That is.

  The tire according to the present invention is provided so as to stand along the circumferential direction of the tire body and the tire body and from the grounding surface side of the tire body toward the rotating shaft side, and a plurality of spaces inside the tire body are formed. And at least one partition portion for dividing the air chamber.

  According to such a configuration, at least one partition portion provided so as to stand along the circumferential direction of the tire body and from the ground contact surface side of the tire body toward the rotating shaft side is a space inside the tire body. Is divided into a plurality of air chambers, for example, even if one portion of the tire body is damaged, the air pressure of only the air chamber corresponding to the damaged portion is reduced. On the other hand, since a plurality of air chambers are formed independently, even if the air pressure of some of the air chambers decreases, the remaining air chambers are not affected by this, and the predetermined air pressure that was initially applied To maintain. Therefore, even when the tire body is damaged at one place, a vehicle using such a tire can maintain a safe running due to the presence of an air chamber that maintains a predetermined air pressure.

  According to such a configuration, since the tire body and the partition are integrally formed, the strength of the partition is improved.

  ADVANTAGE OF THE INVENTION According to this invention, even if a tire main body receives damage at least one place, the tire which can maintain safe driving | running | working of a vehicle etc. can be provided.
