Multi-cavity non-pneumatic tire based on metal spring net surface support

Abstract

The invention discloses a multi-cavity non-pneumatic tire based on metal spring mesh surface support. The multi-cavity non-pneumatic tire comprises a mesh surface formed by weaving metal spiral springs, a tire body is connected outside the mesh surface, a bead toe integrally formed with the tire body is constructed at the root of the mesh surface, a buffer cavity is formed between the bead toe and the tire body, the outer surface of the mesh surface is connected with the inner wall of the tire body, a rim is assembled on the outer surface of the bead toe, and the buffer cavity is communicated with the outside through the bead toe and the rim. The tire provided by the invention meets the driving requirements of non-paved pavements and various paved pavements, the bearing and buffering performances of the tire are not influenced after the tire body is punctured and punctured, the tire has higher safety, and meanwhile, the tire can be applied to military or police wheeled vehicles, and has the characteristics of bullet and elastic piece penetration resistance, flame retardance, explosion prevention and the like; and foreign matters are prevented from entering the tire, so that the problems of service life reduction, dead weight increase and the like are solved. The invention is applicable to the technical field of tires.

Description

technical field [0001] The invention belongs to the technical field of tires, and in particular relates to a multi-cavity non-pneumatic tire supported by a metal spring mesh surface. Background technique [0002] Because existing tires adopt a pneumatic structure, such pneumatic tires are easy to puncture and blow out, threatening the driving safety of vehicles. At present, in order to avoid the occurrence of problems such as puncture, the tire structure with metal helical springs woven into spring mesh is used to replace the tire, so that the tire does not need to be inflated and the problem of puncture is avoided. However, due to the tire structure formed by the metal spring mesh In the process of advancing, there are often branches, gravel, etc. stuck on the metal spring mesh surface, and the spring is damaged; the existing tire structure also has a track-type tire or multiple metal spring mesh The metal spring mesh surface is connected to the tire, but this kind of craw...

Problems solved by technology

At present, in order to avoid the occurrence of problems such as puncture, the tire structure with metal helical springs woven into spring mesh is used to replace the tire, so that the tire does not need to be inflated and the problem of puncture is avoided. However, due to the tire structure formed by the metal spring mesh In the process of advancing, there are often branches, gravel, etc. stuck on the metal spring mesh surface, and the spring is damaged; the existing tire structure also has a track-type tire or multiple metal spring mesh The metal spring mesh surface is connected to the tire, but this crawler structure plays the role of improving the ground adhesion, but cannot fully prevent foreign matter from entering the tire from the side of the tire formed by the metal spring mesh surface.
