Pre-tightening type bending plate tire and manufacturing method thereof

Abstract

The invention discloses a pre-tightening type bending plate tire. The pre-tightening type bending plate tire comprises a rim, a wheel disc set arranged on the outer surface of the rim, a girdle and tread rubber, wherein the girdle and the tread rubber are sequentially arranged on the periphery of the wheel piece set. Three or more mounting grooves are formed in the outer ring surface of the rim inthe axial direction, and multiple radial through holes are formed in the outer ring surface of the rim in the radial direction. The wheel piece set is composed of multiple S-shaped wheel pieces, eachwheel piece comprises a mounting section, a neck bend, a straight section, a shoulder bend and a working section, mounting holes and tensioning holes are formed in the mounting sections, fixing holesand hollowed-out holes are formed in the working sections, an outer ring body is enveloped by all the wheel pieces in the wheel piece set along the outer surface of the rim, in an inner cavity of theouter ring body, the mounting section of each wheel piece is in lap joint to the mounting section of the adjacent wheel piece, and the tensioning hole of each wheel piece, the mounting hole of the adjacent wheel piece and the radial through holes are fixed together through fasteners. The tire has reliable safety and durability and good control and road holding performance.

Description

technical field [0001] The invention relates to the technical field of non-pneumatic tire manufacturing, in particular to a pre-tightened bent-plate tire and a manufacturing method thereof. Background technique [0002] Pneumatic tires commonly used at present, after more than a hundred years of development, the technology has been quite mature, the structure is relatively simple, and the elasticity from the whole to the part is very good, but its manufacturing process is complicated, especially when it is developed to the radial tubeless tire. After that, in terms of meeting the increasingly stringent requirements of vehicles on tires such as high speed, heavy load, durability, comfort and safety, the corresponding technical improvement of pneumatic tires has been stagnant for a long time, especially the chronic problems of inflation leakage and tire blowout , has always made users feel deeply inconvenient, but also bears the worry of driving accidents. Therefore, many peo...

Problems solved by technology

The practicability of the above-mentioned tires is not ideal, and there is a serious defect, that is, the elastic load-bearing parts used are all built up in the form of building blocks along the circumferential surface of the rim or hub, and are not fully preloaded. Heavy load or high-speed bumpy impact, and the elastic load-bearing parts have to be designed to be large in size or in large numbers. These structural disadvantages make it difficult for the tire to dissipate heat or drain water during operation. Once foreign matter such as sand enters the carcass, it will Will affect the normal performance of the tire function
