Tricycle non-inflatable inner tube

Abstract

The invention provides a non-inflatable inner tube of a tricycle, which is arranged in an outer tube of the tricycle and serves as a traditional inflatable inner tube. The bearing capacity and the service life are obviously superior to those of the traditional inflatable inner tube; the properties of transmission, adhesion, shock absorption and impact force absorption of the non-inflatable inner tube are comparable to those of a pneumatic tire. The non-inflatable inner tube of the tricycle is characterized in that the non-inflatable inner tube of the tricycle is arranged in an outer tube of the tricycle and serves as the inflatable inner tube; the outside of a liner is in contact with a rim of a wheel and the inside of a tread of the tricycle outer tube, and the inside of the liner is wrapped on an oval spiral gapless spring; the oval spiral gapless spring is a spiral spring formed by winding a spring steel wire, no gap exists between round flat oval rings, and then the round flat ovalrings are wound into a circle. The section of the non-inflatable inner tube is in a round flat oval shape, and the non-inflatable inner tube is in fully contact with and completely attached to the interior of a tire tread to support the tire tread bearing load.

Description

technical field [0001] The invention relates to a non-inflatable inner tube. Background technique [0002] The appearance of pneumatic tires is a great progress in the history of tire development. While bringing comfort to people, because the air molecules are very small, they will run out from the gaps in the rubber molecules, so pneumatic tires often need to be filled with air. In addition, pneumatic tires are easy to be punctured by sharp objects such as nails and glass, and sometimes they will blow out, which is very troublesome to repair. If it is a light bicycle tire that is flat, it is easier to push it to repair the tire. If it is a heavy electric bicycle, motorcycle, or tricycle tire that is flat and push it to repair the tire, it will be laborious. Be exhausted. [0003] Non-pneumatic tires refer to tires that achieve shock absorption and cushioning performance without the use of air pressure, that is, tires that do not need to be inflated, and only use the mater...

AI Technical Summary

Problems solved by technology

The disadvantages are: the production process is difficult, the power consumption is high, the carcass is heavy, the cushioning performance is poor, and the cost is too high

This kind of tire is made of polyurethane material into a foam-like solid tire. The advantages are beautiful appearance and light weight. The disadvantages are easy aging, bodiless, non-wear-resistant, and high rolling resistance.
