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.

Embodiment Construction

[0023] As shown in the figure, this non-inflatable inner tube is arranged in the electric bicycle cover tire, acts as the pneumatic inner tube; Its lining ring 1 outside is in contact with the rim of the wheel and the tread inside of the electric bicycle cover tire, and the lining ring 1 is wrapped in an oval spiral On the gap spring 2; the upper and lower parts of the lining ring 1 are all densely covered with wire rings 5, so as to offset the targeted damage of the tire by the concave gap between the round flat oval circle and the round flat oval circle.

[0024] Elliptical spiral gap spring 2 is a helical spring made of spring wire coils. There is a gap between the round and flat oval circles, and the distance between the round and flat oval circles may be equal. Then it is wound into a circle; its section 4 is round, flat and elliptical, and it is in full contact with the inside of the tread of the tire, fully fitted, and supports the load bearing of the tire tread.

Abstract

The invention provides a non-inflatable inner tube of an electric bicycle, which is arranged in an outer tube of the electric bicycle and serves as a traditional inflatable inner tube. The bearing capacity and the service life are obviously superior to those of a traditional inflatable inner tube; the properties of transmission, adhesion, shock absorption and impact force absorption of the tube are comparable to those of the inflatable inner tube. The non-inflatable inner tube of the electric bicycle is characterized in that the non-inflatable tube is arranged in an outer tube of the electricbicycle and serves as an inflatable inner tube; the outside of a lining ring is in contact with the rim of a wheel and the inside of a tread of the outer tube of the electric bicycle, and the inside of the lining ring is wrapped on an oval spiral clearance spring.

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...
