A solid tire dismounting and anti-tire structure

Abstract

The invention discloses a solid tire demounting and tire-dropping preventing structure which comprises a solid tire and a rim, wherein the solid tire is installed on the rim; the rim comprises a bead seat, wheel flanges are arranged on the two sides of the bead seat, and at least one wheel flange is detachably connected with the bead seat; the wheel flange detachably connected with the bead seat is connected with a wheel flange extending ring, the wheel flange extending ring is connected with an extending ring flange, the bead seat is connected with a bead seat flange, and the extending ring flange is connected with the bead seat flange through a bolt; or the wheel flange detachably connected with the bead seat is connected with the wheel flange extending ring, the bead seat is connected with a bead seat extending ring, and the wheel flange extending ring is connected with the bead seat extending ring through a bolt; a chock block is arranged on the bead seat, and a slot matched with the chock block is formed in the solid tire; and / or a stop bulge is arranged on each wheel flange, and a groove matched with the stop bulge is formed in the solid tire. The solid tire demounting and tire-dropping preventing structure can effectively solve the demounting and tire-dropping preventing problems of the solid tire.

Description

technical field [0001] The invention relates to a structure which facilitates disassembly and assembly of solid tires and can effectively prevent the solid tires from coming off, and belongs to the field of vehicle tires. Background technique [0002] Solid tires have excellent properties such as puncture resistance, high temperature resistance, wear resistance and no tire blowout. Even in harsh environments and heavy loads, they still maintain good performance, thus ensuring transportation safety. Although the price of solid tires is two to three times more expensive than pneumatic tires, its service life can reach four to six times that of pneumatic tires, and it avoids the trouble of repairing tires. Calculate the long-term use cost, solid tires can be doubled than pneumatic tires. [0003] Solid tires are technically mature and have the above-mentioned advantages, but the installation of solid tires is relatively difficult, and the performance of solid tires will inevita...

AI Technical Summary

Problems solved by technology

Solid tires are generally molded by casting the load-bearing frame and the tire material together. When installing the tire, it is necessary to use tools to pull the diameter of the solid tire larger than the rim to install the rim, so it is easy to cause damage to the load-bearing frame and / or tire material, such as solid tire hoops The steel wire is easily broken during installation due to its lack of elasticity

Once the load-bearing frame and / or tire material is damaged, the entire tire has to be replaced, resulting in waste of material

[0004] In addition, existing solid tires all have the problem of bodiless, the main reasons are: 1 when the temperature of the solid tire material changes, the material will soften and cause bodiless

2. When the solid tire is impacted by external forces such as braking and load, it will cause the tire to fall out

3. Solid tires are only equipped with steel wires for positioning, and there is no clamping device, which cannot achieve the clamping effect between the tire and the hub.

4. When the solid tire is stretched by tools during installation, the internal structure is deformed, resulting in bodiless
