The present invention discloses a type of secure and efficient wheel assembly using fluid or solid stuffing materials so as to minimize the blowout risks, a wheel rim transmission assembly, an energy exchanging arrangement used in transporting system, and a vehicle energy storage system, as well as corresponding methods for manufacturing and preparing such assemblies and arrangements in applications.

What is claimed is: 
     
         1 . A vehicle wheel comprising:
 a steel rim defining a first concave chamber therein; and   an outer tire assembled on the steel rim, the outer tire defining a second concave chamber therein, the first concave chamber of the steel rim and the second concave chamber of the outer tire cooperatively defining an inner cavity in the vehicle wheel,   wherein the depth of the first concave chamber of the steel rim is increased to thereby cause that a volumetric space of the first concave chamber of the steel rim is larger than that of a known concave chamber of a known steel rim, and the depth of the second concave chamber of the outer tire is decreased to thereby cause that the volumetric space of the second concave chamber of the outer tire is smaller than that of the known concave chamber of the known outer tire;   wherein the volumetric space of the first concave chamber of the steel rim is at least a half of the volumetric space of the inner cavity, and the volumetric space of the second concave chamber of the outer tire is at most one third of the volumetric space of the inner cavity;   wherein the distance between the circumferential edge of the steel rim and the circumferential edge of the outer tire is within a range from 0.5 cm to 5 cm;   wherein a cross section of the second concave chamber of the outer tire is squared, or a flat underside of the outer tire is transversely flatted, or upwardly curved, under a loading pressure, the outer surface of the wheel is transversely flatted, or the outer tire is embodied as flat shape, and two sidewalls of the outer tire are eliminated;   wherein at least one inner support is disposed within the outer tire to protect the wheel from a blowout accident.   
     
     
         2 . The vehicle wheel as recited in  claim 1 , wherein the at least one inner support is made of metal, plastic, foam material, rubber, soft substance, or any compound thereof, and the volume of the at least one inner support is less than the volume of the inner cavity. 
     
     
         3 . The vehicle wheel as recited in  claim 1 , wherein a stuffing material is filled in the inner cavity, the stuffing material is capable of bearing pressure and occupying a space larger than one third of a volumetric space of the inner cavity of the vehicle wheel, and the stuffing material is selected from a group of consisting of cream material, jelly material and colloid material. 
     
     
         4 . The vehicle wheel as recited in  claim 3 , wherein the stuffing material further comprises additives, and the additives comprises leak-proof liquid and tire-repairing liquid. 
     
     
         5 . The vehicle wheel as recited in  claim 1 , wherein the inner supports are T-shaped, and each of the T-shaped inner supports comprises a vertical supporting member and a lateral reinforcing member, the vertical supporting member is clipped on the steel ring, and the lateral reinforcing member is disposed overlappedly along the inner circumferential surface of the outer tire, and an outer ring is provided for coupling two T-shaped inner supports together. 
     
     
         6 . The vehicle wheel as recited in  claim 1 , wherein a plurality of clamping boards is provided for supporting the wheel, each of the clamping boards has a height being at least half of the height of the sidewall of the outer tire, and there is a distance between the ground and the clamping board edge, ranging between 0.5 and 5 cm, so as to protect the wheel from a blowout accident. 
     
     
         7 . The vehicle wheel as recited in  claim 1 , wherein a plastic membrane or coating is respectively disposed on an inner side of the outer tire and the steel rim. 
     
     
         8 . The vehicle wheel as recited in  claim 1 , further comprising an inner tube received in the inner cavity of the vehicle wheel. 
     
     
         9 . The vehicle wheel as recited in  claim 8 , wherein the inner tube is divided into two or more parts for simplifying the assembly and maintenance, stuffing materials for filling in the inner tube are selected from cream substance, gluing substance being pre-treated. 
     
     
         10 . The vehicle wheel as recited in  claim 9 , wherein a tension band is disposed between the inner tube and the outer tire for partially or entirely bearing the tension and bearing the pressure of the stuffing materials, the tension applied to the outer tire is lessened, so that the lifespan of the outer tire is prolonged, and the tension band is made of plastic, rubber, or metal. 
     
     
         11 . The vehicle wheel as recited in  claim 8 , wherein two round shaped clamping boards are coupled together by screw-bolts means to form a main frame of the wheel adapted for replacing steel rim, the inner tube and the outer tire are received in a groove defined by the pair of clamping board, wherein the axis of the round shaped clamping board are coaxially coupled to a driving shaft, after the clamping board is fastened, the inner tube and outer tire are squeezed into the groove defined by the clamping boards so that the inner pressure of the inner tube is correspondingly increased for bearing a loading force. 
     
     
         12 . The vehicle wheel as recited in  claim 1 , wherein an interlocking structure for coupling the outer tire and steel rim is provided. 
     
     
         13 . The vehicle wheel as recited in  claim 1 , wherein the outer tire comprises a rubber surface coat, and the outer tire and the rubber surface coat is bond together or removably attached.
