Description

Electricity-saving electric friction tire

Technical Field

The utility model relates to an electricity rubs tire technical field, especially relates to an electricity of power saving rubs tire.

Background

At present, when a common electric motorcycle tire is used on a long riding way, the endurance mileage is poor, the market has more overload current situations, and when the common electric motorcycle tire is used on a riding way, the common electric motorcycle tire is large in contact area with the ground, large in heat productivity, large in running resistance, short in endurance, and brings great trouble to riders.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a power-saving electric motorcycle tire.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a power saving electric friction tire, includes tread layer, inner surface layer, child limit, steel wire winding and casing ply, inner surface layer, steel wire winding encircle in proper order and form a week, the casing ply turns back to the child limit along the steel wire winding and encircles and form a week.

Preferably, the material of the cord fabric layer is nylon cross-ply cord yarn.

Preferably, the cord fabric layer is folded back along the steel wire ring until the tire bead surrounds to form a circle, and the winding height of the cord fabric layer is respectively increased by 5 mm.

Preferably, the tread center pattern is designed with a wide smooth pattern.

Preferably, the tread rubber used at the tread layer has a hardness of 58SA-65 SA.

The utility model has the advantages that:

1. the tread rubber is combined with the buffer layer in a matched mode by adopting a high-hardness formula, the puncture-proof and load-bearing capacity of the tire is greatly improved, the traveling is effectively ensured, and the trouble of ordinary charging is reduced.

2. The tread is combined with the unique bead design, so that the rolling resistance of the tire during riding can be greatly reduced, the purpose of saving electricity is achieved, and the endurance is improved.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a power-saving electric friction tire comprises a tread layer 1, an inner surface layer 3, a bead 4, a bead ring 5 and a cord fabric layer 2, wherein the inner surface layer 1 and the bead ring 5 are sequentially encircled to form a circle, and the cord fabric layer 2 is turned back along the bead ring 5 to the bead 4 to encircle to form a circle.

The cord fabric layer 2 is made of nylon cross ply cord yarns, the cord fabric layer 2 is formed by two layers of crossed and overlapped layers, the high-temperature resistance and the stability are good, and the cord fabric layer mainly bears the pressure and the impact of filling air, and the filling air can bear the load.

The cord fabric layer 2 is turned back along the bead ring 5 to the bead to form a circle in a surrounding way, the winding height of the cord fabric is respectively increased by 5mm (1P/2P:30mm/20mm) which is different from that of a common electric friction tire with the same specification, the rigidity of the tire side is improved, and the deformation of the bead is reduced during loading, so that the rolling resistance in riding is reduced.

The tread center pattern adopts a wide smooth pattern design, the tread strength is increased, the pattern groove deformation is reduced in the driving process, the ground contact surface is reduced, and the resistance is effectively reduced.

The hardness of the tread rubber used at the tread layer 1 is 58SA-65SA, so that the wear resistance and the heat resistance are better, and the rolling resistance performance is greatly improved.

The unique bead bump design is different from the common electric friction tire bead, the longitudinal rigidity of the bead is enhanced, the deformation of the bead is less than that of the common electric friction tire bead during riding, and the wind resistance during riding is reduced.

Therefore, the tread rubber adopts a high-hardness formula and is matched and combined with the buffer layer, the puncture-proof and load-bearing capacity of the tire is greatly improved, the traveling is effectively ensured, and the trouble of ordinary charging is reduced; the tread is combined with the unique bead design, so that the rolling resistance of the tire during riding can be greatly reduced, the purpose of saving electricity is achieved, and the endurance is improved.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
