Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for transport devices, in particular to a wheel with steel parts inside. Background Art

[0002] Leather and eventually rubber were added to the circumference of the wheel to dampen the transfer of impact forces as the wheel traversed irregular terrain or surface debris. Heavier load bearing products (e.g., bicycles, heavy duty carts, and cars) typically have wheels that utilize pneumatic tires. Lighter load bearing products (e.g., suitcases, carts, and mobile tool boxes) typically use casters or wheels of simpler construction, such as casters or wheels formed of metal, plastic, rubber, or simple combinations thereof.

[0003] For example, the Chinese patent: application number is 2020202263835, and the patent name is a wheel, "including: a wheel core, an insert and a tire; the insert is fixed to the outer periphery of the wheel core; the tire is fixed to the outer periphery of the insert; the ratio of the thickness value of the tire to the thickness value of the insert is greater than or equal to 0.4 and less than or equal to 3; the tire is formed with a wrapping portion; the wrapping portion covers and is fixed to the side of the insert." In the above technology, the structure of the wheel is composed of a wheel core, an insert, and a tire. However, during use, the wheel will pass through different road conditions. The road will be uneven, with pits or stones, etc., and the wheel will experience long-term impact when moving. In the above technology, the connection between the wheel core and the insert has neither a special connection method nor a threaded connection. It is an interference fit or glue bonding connection in the commonly used technology. However, the disadvantages of the above two connection methods are that the wheel core and the insert are easy to fall off and separate when they are constantly experiencing impact, and when the impact force applied to the insert is too large, the insert will break.
