For the bearing wheel with the braking function, the friction plate clearance of the brake does not need to be adjusted again.

2. The support sleeve and the wheel hub are preferably connected through bolts, and are convenient to assemble and disassemble, so that the tire can be quickly replaced.

3. The outer tire body is directly injection-molded outside the support sleeve, so that the assembly steps of the outer tire body and the support sleeve can be omitted, and the outer tire body and the support sleeve are connected more firmly.

4. The outer side surface of the supporting sleeve is coated with glue and/or is provided with anti-skidding lines, so that the connection strength of the outer tire body and the supporting sleeve can be further improved, and the outer tire body and the supporting sleeve are not easy to skid under stress.

The present invention will be described in further detail with reference to the accompanying drawings and examples; however, the present invention is not limited to the embodiment.
