Commonly, there are several drawbacks of wheels available in the market:
Poor security: the tires mounted to the wheel rim are subject to blowout accidents which cost and jeopardize human lives.
The wheel assembly is made of inferior materials, such as the air-tightness of the inner tube of the tire is not satisfied in most cases.
The structure of such wheel is not well designed, for example, the inner cavity and curvature of outer cover of the tire are not desired to prevent the
turning radius of the wheel from being varied from time to time.
And two side wall of outer cover of the tires are too high causing unnecessary
raw material wasting.
Expensive costs: the landing circumferential surface of the tire outer cover is worn off easily, while two side walls of the outer cover are still of good shape, so the disposal of such tire is not an economic way.
Inconvenience: the tire inner tube should be refilled from time to time.
According to the wheel-axis mechanism and movable
pulley mechanism, the conventional transmission designed is not appropriate.
Needless to say, the conventional method is not efficient.
What is more, other conventional wheel transmission method, such rotational fans, propellers of vessels and airplanes, and blade wheel of the fluid pump are subject to this inherent inefficiency.
However, the dynamic force is not transmitted in an accurate manner thus consuming considerable energy and causing energy waste.
In a long run, the friction between the tire and mechanical parts will reduce the
life span of vehicle, and such design is not suitable for withstanding harsh conditions, such as not suitable for being mixed with water and mud.
In addition, if the tire is less stuffed, the tire will be softened, the shortened
turning radius will cause the transmission effect deteriorated.
However, there are no such wheels applied in the motored vehicles.
For those transmission utilizing electrical means, there existed some problems to be solved, such as
high energy consumption, poor endurance.
However, conventional energy supplying system comprises a plurality of drawbacks; first of all, the recharging and the refueling process are not safe.
Third, the cruising continuality of vehicles is limited, for example, the electrical vehicle can
cruise no more than 100 miles after fully charged.
Fourth, the dynamic force is not sufficient.
After a
continuous operation, the electrical energy stored within the electrical vehicle will be weakened thus limiting the speed of such vehicle.
Fifth, the energy sources are not universally applicable in different applications.
Sixth, the conventional storage battery comprises a plurality separate battery units which are not convenient and
user friendly.
