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.
