Embodiment Construction

[0023] As shown in the figure, the non-inflatable inner tube of the tricycle is arranged in the outer tire of the tricycle, and serves as an air-filled inner tube; the outside of its lining ring 1 is in contact with the rim of the wheel and the tread inside of the outer tire of the tricycle, and the inside of the lining ring 1 is wrapped in an oval spiral without gaps. On the spring 2; a gap is set on the section 3 of the lining ring 1, which is convenient for setting the elliptical spiral gap spring 2.

[0024] Elliptical spiral gapless spring 2 is a helical spring made of spring wire coils, there is no gap between the round and flat oval circles, and then it is wound into a circle; its cross section 4 is round and flat Oval shape, it is in full contact with the inside of the tire tread and fits completely, supporting the load bearing of the tire tread;

[0025] Steel wire rings 5 ​​are densely covered in the upper and lower parts of the lining ring 1 to offset the targeted d...

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...
