     DETAILED DESCRIPTION OF THE INVENTION 
     With reference to the accompanying drawings, self-powered motorcycle and bicycle according to preferred embodiments of the present invention will be described in detail. 
       FIGS.  1  to  3    are side views illustrating a motorcycle, a bicycle, and a three-wheeled vehicle equipped with generators. 
     As illustrated in  FIGS.  4  and  5   , a shock absorber frame housing  101 , which is formed in a long cylindrical shape and has a hollow inside, includes a disc-shaped fixing plate  101   b  fixed on an upper end portion thereof so that the upper end portion is stopped. A lower end portion of the shock absorber frame housing  101  has a split space, and a shock absorber frame  102  is inserted into the lower end portion. 
     Rack gear moving holes  101   a  are formed in both sides of the shock absorber frame housing  101  in the longitudinal direction, and a rod which juts rack gears  102   a  attached to both sides of the shock absorber frame  102  and moves the rack gears  102   a  in the vertical direction. 
     As illustrated in  FIG.  6   , a shock absorbing spring  103  and a spring guide  104  are inserted into the cylindrical hollow inside of the shock absorber frame  102 . The shock absorber frame  102  into which the shock absorbing spring  103  and the spring guide  104  are inserted is inserted into the shock absorber frame housing  101 , and a lower end portion of the shock absorber frame  102  is fixed to an end of a wheel rotating axle. 
     A structure in which a shock absorber frame housing  101  and a shock absorber frame  102  are coupled in the same form as the above is fixed to the other end of the wheel rotating axle. That is, a pair of the structures in each of which the shock absorber frame housing  101  and the shock absorber frame  102  are coupled are fixed at both ends of the wheel rotating axle at a predetermined interval. 
     The lower end portions of the pair of the coupling structures of the shock absorber frame housing and the shock absorber frame are respectively fixed at both ends of the wheel rotating axle at the predetermined interval, and the upper end portions thereof are connected horizontally by a connection member so as not to be isolated or separated from the wheel rotating axle. 
     The upper end portions of the coupling structures in which the shock absorber frame housing and the shock absorber frame are coupled are connected horizontally by the connection member. A vertical portion is extended upwards from the central portion of the connection member connected horizontally to a steering handle in a vertically cylindrical shape so that a front wheel and the coupling structure of the shock absorber frame housing  101  and the shock absorber frame  102  can change the direction in the left and right directions. 
     The connection member which is connected horizontally and extends to the handle in the vertically cylindrical shape is called a horizontal and vertical connection member  101   c.    
     A vertically cylindrical middle portion of the horizontal and vertical connection member  101   c  is connected to a connection portion derived from a body of a motorcycle or a bicycle so as to receive fluctuation energy of a load repeating vertical generation while a motorcycle or a bicycle is driving. 
     As described above, since being connected to the body of the motorcycle or the bicycle, the connection member receives fluctuation energy of a load, including the weight of the body of the motorcycle or the bicycle and the weight of a user during driving. The received load is transmitted to the shock absorber frame housing  101 , and then, is transmitted to the shock absorber  102 . 
     As described above, the load transmitted to the shock absorber frame  102  is transmitted to the wheel axle, and then, the load transmitted to the wheel axle is transmitted to the wheel so as to be supported and moved by the wheel while landing on the ground. 
     The load generates repulsive power upwards while being supported and moved on the ground by the wheel. The repulsive power generated upwards is transmitted to the shock absorber frame  102  connected to the wheel axle. 
     As described above, the repulsive power transmitted to the shock absorber frame  102  is absorbed and resisted by the shock absorbing spring  103  and the spring guide  104  mounted inside the shock absorber frame to generate energy so that the shock absorber frame  102  is repeatedly moved in a vertical direction. The shock absorber frame  102  moving in the vertical direction repeatedly moves the rack gears  102   a,  which are fixed at both sides of the shock absorber frame, in the vertical direction. 
     The rack gears repeatedly moving in the vertical direction are connected to pinion gears, which are mounted on both sides of the outer wall of the shock absorber frame housing  101  and are connected to a power generator  100 , to rotate the pinion gear  109 , thereby rotating the power generator. 
     The shock absorber frame  102  includes a disc-shaped partition  102   c  fixed and attached in a horizontal direction to support the shock absorbing spring  103  inside the shock absorber frame, and the shock absorbing spring  103  for lessening shock is formed on the disc-shaped partition. The spring guide  104  for pressing the shock absorbing spring  103  is mounted on the shock absorbing spring  103 , thereby reducing shock generated while driving. 
     An upper end portion of the spring guide  104  is fixed on the bottom surface of the disc-shaped fixing plate  101   b,  which has the same diameter as an upper end portion of the shock absorber frame housing  101 , together with the upper end portion of the shock absorber frame housing  101 , so that the shock absorber frame  102  inserted into the shock absorber frame housing  101  can be repeatedly moved smoothly in the vertical direction without being isolated or separated. In this instance, since a lower end portion of the spring guide is pressed to get in contact with the shock absorbing spring  103  inserted into the shock absorber frame, a shield for the purpose of pressurization is needed. 
     Two anti-rotation protrusions  104   a  are formed at both sides of the spring guide  104  to a predetermined length in the longitudinal direction. The shock absorber frame  102  includes anti-rotation protrusion guide holes  102   b  formed at both sides thereof to provide a rod of a size to allow the two anti-rotation protrusions  104   a  to protrude and to be movable. 
     In this instance, the anti-rotation protrusion guide holes  102   b  have the same width as the anti-rotation protrusions to allow a vertical movement and not to allow a horizontal movement, so that the shock absorber frame  102  cannot independently change the direction to be in the horizontal direction. 
     The spring guide  104  is inserted into the shock absorber frame  102 , and then, is inserted into the shock absorber frame housing  101  together with the shock absorber frame  102 , thereby adjusting the protrusion level of the anti-rotation protrusion  104   a  not to hinder the spring guide from being inserted into the shock absorber frame housing  101 . 
     The self-powered generator  100  is formed to protrude out of the shock absorber frame housing  101 . 
     The driving force of the self-powered generator uses potential energy generated while the user&#39;s weight and the load of the body of the motorcycle or the bicycle are transmitted downwards during driving, and repulsive energy of the wheel and the wheel rotating axle receiving, supporting and transmitting the potential energy. 
     Now, a process that the user&#39;s weight and the load of the body of the motorcycle or the bicycle are transmitted downwards during driving and a process of generating repulsive energy of the wheel and the wheel rotating axle receiving and transmitting the potential energy will be described. 
     During driving, the user&#39;s weight and the load of the body of the motorcycle or the bicycle are transmitted to the shock absorber frame housing connected to the self-powered generator, and the load transmitted to the shock absorber frame housing is transmitted to the spring guide  104  fixed to the disc-shaped fixing plate formed on the upper portion of the shock absorber frame housing. The energy transmitted to the spring guide  104  is simultaneously transmitted to the shock absorbing spring  103  located beneath the spring guide. 
     The shock absorbing spring  103  has an effect by transmitting the load to the shock absorber frame  102  having the spring therein, and the load is transmitted to the wheel and the wheel rotating axle moving on the ground while supporting the user&#39;s weight and the load of the body of the motorcycle or the bicycle. 
     The load transmitted to the wheel and the wheel rotating axle generates repulsive power when there is no place to go down anymore, thereby generating contradictory energy. 
     The generated contradictory energy is transmitted to the shock absorber frame  102  connected to the wheel rotating axle. The contradictory energy transmitted to the shock absorber frame  102  is transmitted to the rack gears fixed and attached to both sides of the shock absorber frame to actuate the rack gears in the vertical direction. The rack gears rotate the pinion gears  109  connected thereto, and the pinion gears rotate a rotor of the power generator to generate power. 
       FIG.  7    is a view illustrating a state in which the shock absorber frame housing and the shock absorber frame are coupled to each other.  FIG.  8    is a view illustrating a state in which a wheel is disposed in between a pair of coupling structures in which the shock absorber frame and the shock absorber frame housing having the self-power generator are coupled with each other.  FIG.  9    is a view and  FIG.  10    is a plan view illustrating a state in which the self-power generators are mounted around the shock absorber frame housing  101 . 
     the self-power generators are mounted around the shock absorber frame housing  101 , and a pair of stator bodies  105  are fixed to face each other, thereby safely fixing and protecting a stator  106 , a rotor  107 , and various members necessary for power generation. 
     Two stators  106  are fixed inside the stator body  105 , and two rotors  107  located inside the two stators are respectively connected to rotary shafts  108 , so that the pinion gears  109  are fixed and attached around the rotary shaft. 
     The pinion gears  109  are fixed at both sides of the shock absorber frame  102 , and are engaged with the rack gears  102   a  protruding out of the rack gear moving holes  101   a  formed in both sides of the shock absorber frame housing  101 . 
     The coupled pinion gears  109  and rack gears  102   a  are different from each other in the direction of energy of each other. 
     The pinion gear  109  is embedded in the stator body together with the power generator  100  to be fixed on the outer wall of the shock absorber frame housing. Since the lower end portion of the shock absorber frame is fixed to the wheel rotating axle and the upper end portion of the shock absorber frame is not fixed, the rack gears  102   a  repeatedly move in the internal space of the shock absorber frame housing in the vertical direction, thereby generating locomotive power of the rack gears formed on the outer wall. 
     The shock absorber frame housing  101  receives the weight of the body of the motorcycle or the bicycle and the user&#39;s weight and transmits them to the shock absorber frame  102 . The shock absorber frame transmits the load to the wheel and the wheel rotating axle. The wheel generates repulsive power while supporting and moving the load energy. 
     The lower end portions of the shock absorber frames  102  are fixed and attached to both ends of the wheel rotating axle, and each of the shock absorber frames  102  has the shock absorbing spring  103  and the spring guide  104  embedded therein so as to absorb load energy acting downwards and generate repulsive energy in the opposite direction. 
     As described above, the rack gears repeatedly move in the vertical direction by the repulsive energy generated in the opposite direction, and the vertical locomotive power of the rack gears rotates the pinion gears  109  connected to the rack gears. 
     The pinion gears  109  formed in the middle of the rotary shaft  108 , and the rotors are respectively attached to both ends of the rotary shaft. 
     One-way gears  110  are mounted on both ends of the rotary shaft, which is coupled to the rotor, so as to run idle in one direction, so that the rotor in the stator rotates in one direction to generate electricity.
