Description

Technical Field

[0001] The utility model relates to the technical field of foam wheels, in particular to a PU foam wheel. Background Art

[0002] Tires are generally divided into non-solid pneumatic tires and solid tires. Solid tires are mostly used on various equipment that can move short distances, and are generally made of PU foam. The full name of PU is polyurethane, which is a polymer compound. Compared with ordinary PVC, it has better stability, chemical resistance, resilience and mechanical properties, so it is more suitable for use as a tire manufacturing material.

[0003] The existing foam wheel cannot be disassembled and replaced at will. In addition, when the road conditions are bad or the tire assembly error is large, the wheel center and the wheel frame are not integrated, which may cause relative displacement of the wheel center and the wheel frame, causing danger. In addition, because the wheel center is composed of multiple sections, the stress conditions are changed, and the load-bearing force is concentrated at the joints of the sections, which may easily cause deformation and cause danger.

The two groups of connecting rings are respectively fixedly connected to the inside of the two groups of spokes, and the two groups of connecting rings are connected by a number of connecting columns.
