Bead protection mechanism of vacuum rubber tire and installation method thereof

Abstract

The invention discloses a bead protection mechanism of a vacuum rubber tire, which comprises a bead, a fastening wire, a reinforcing rib and an extrusion cavity. , the surface of the airtight layer is fixedly connected with the sidewall, and the upper part of the airtight layer is fixedly connected with the carcass, the upper part of the sidewall is fixedly connected with the tread, the carcass and the tread are fixedly connected with the belt layer, the bead Fastening steel wires are interspersed in the inner part of the vacuum rubber tire, and the invention also discloses an installation method of the bead protection mechanism of the vacuum rubber tire, which includes the following steps: installation of the push plate, installation of the reinforcing ribs, installation of the extrusion structure, and forming of the vacuum tire; The bead protection mechanism proposed by the invention uses the limiting clip to limit the position of the steel wire, and cooperates with the push plate and the elastic rod body to squeeze it, so as to prevent it from sliding freely inside the bead.

Description

technical field [0001] The invention relates to the technical field of vacuum tires, in particular to a bead protection mechanism of a vacuum rubber tire and an installation method thereof. Background technique [0002] Vacuum tires are tubeless pneumatic tires, also known as "low pressure tires" and "pneumatic tires". Vacuum tires have high elasticity and wear resistance, as well as good adhesion and heat dissipation, especially all-steel radial vacuum tires. Economical and durable, the bead refers to the part of the tire installed on the rim. It can withstand the tensile force generated by the internal pressure, and at the same time, it can overcome the lateral force of the tire during cornering, so that the outer tire does not come off the rim. This results in the following disadvantages in the actual use of the bead: [0003] 1. The tire bead tightens the rim of the car through the inner steel wire, so that the vacuum tire is fixed on the wheel hub. After long-term use,...

AI Technical Summary

Problems solved by technology

[0003] 1. The bead tightens the rim of the car through the internal steel wire, so that the vacuum tire is fixed on the wheel hub. After long-term use, the steel wire causes wear to the inside of the bead, which increases the movable space of the steel wire and causes the steel wire to be in the bead. Shaking in the middle affects its holding effect on the rim;

[0004] 2. After the steel wire inside the bead holds the rim for a long time, there will be strangle marks on the inner extrusion of the bead, resulting in a reduction in the thickness of the bead. ;

[0005] 3. After the internal steel wire of the traditional bead is slightly loose, the bite force on the rim is reduced, which causes the micro-movement of the entire vacuum tire, which poses a safety hazard
