       BRIEF SUMMARY OF THE INVENTION  
       [0002] The present invention is a frame structure constructed of any one of a number of materials used separately to build a 4×-suspension system frame. The most favorable material due to it&#39;s ductile strength and light weight to be used, is aluminum 5052, 094 thick. The second best material is carbon fiber, third is plastic, fourth is steel, and fifth is mild steel. The sixth is titanium that is the best material to use for the frame due to its superior strength and light weight. The most unfavorable quality of titanium would be its high price, compared to the other mentioned materials.  
       [0003] Methods of construction would vary according to material used for the frame. In the case of an aluminum frame set the parts would be punched out of a sheet of aluminum by a C.N.C. punch press, then necessary bends would be made to the parts by a break press. Frame construction would be completed by a minimal amount of gas tungsten arc welding to connect certain parts of frame structure such as upright motor mounts. Carbon fiber frame sets would be cut out of a sheet of carbon fiber, and screwed together with screws, nuts, lock washers and washers. Plastic frames could be produced by use of injection molds with an upright motor mount and main frame in one piece. Stainless steel, mild steel and titanium frame sets would be constructed virtually the same as the aluminum process.  
       [0004] This frame structure is designed to mount 4 motors in an upright standing position, in what would be the passenger compartment of an automotive vehicle. Each one of these motors is equipped with a vertically mounted pinion screw. These are attached to the shaft of the motors and held secure by a horizontal allen screw through the head of the pinion screw. The pinion arm nut connector extension travels vertically up and down pinion screw. When electrical input is applied in forward or reverse mode by momentary toggle switches connected to each motor by way of a battery powered switch box that can be directly wired to vehicle or remotely controlled. Pinion extensions are mounted at front end to contact plate&#39;s front and rear. These extensions are held in place in close proximity near each one of four road wheels by ⅛ of an inch cable ties.  
       [0005] Contact plates have slotted holes in them to accommodate main frame vertical guides. These guides keep contact plates centered, and allow for vertical travel of contact plates up or down in small increments, or the total length of pinion screw.  
       BRIEF SUMMARY OF THE INVENTION  
       [0006] The front contact plate is also used to mount the steering servo too. This enables vehicle to perform right and left turns. The servo is mounted at the front wheels by small diameter rods that mount to the front wheel swivels. The servo is operated by battery power and may be directly wired to switch box or wireless remotely operated. A motor is mounted to the rear contact plate to propel the vehicle either in forward or reverse by a pinion on the shaft of the motor, that engages with a gear mounted to one rear wheel also battery operated wired or wireless remotely controlled.

     DETAILED DESCRIPTION  
     [0012]FIG. 1 is a top view looking down on the invention of frame set  1 . Also shown are top views of the four suspension system magnetic motors  5  attached to the main frame  1  upright motor mounts  4 . Also shown in this view is the pinion extensions  10  extending from the upright motors  5  to their mounted positions on the front  2  and rear  3  contact plates&#39;. Front contact plate  2  also displays servo  7  mounted on front contact plate  2  with rods  11  from servo  7  extending outward to swivel mounts  12  that enable steering of front wheel  19  assembly axle studs  18  and road wheels  19 . Also shown on contact plates&#39; front  2  and rear  3  are slots for main frame  1  vertical guides. Also shown on rear contact plate  3  is drive train motor  6  pinion  14  motor and drive axle mount  13 , the drive gear  15  that connects to right rear wheel  19  and makes contact with motor shaft pinion  14  which transfers energy from motor  6  to wheel  19  gear  15  to produce forward or reverse motion. This action creates momentum that propels frame structure. Servo  7  and drive train motor  6  are battery powered by wire or wireless remote control.  
     [0013]FIG. 2 is a side view of frame set structure. This view displays the relationship of frame parts and components from a side view front to rear. Shown here is a side view of the upright motors  5  as they are attached to the upright motor mounts  4 . Also shown is a clear view of the pinion screws  9  and pinion nut connector extension  16  back down onto threads of pinion screw  9  once it reaches the top of pinion screw  9 . Also there is a area at the bottom of the pinion screw  9  that has no threads on it to prevent tightening of pinion nut connector extension  16  against main frame  1 , also once pinion nut connector extension  16  travels to its lowest point of pinion screw  9  the weight of the main frame  1  upright motor mounts  4  and magnetic motors  5  assist in reengagement of pinion nut connector extension  16  and the threads on pinion screw  9 . Also shown in this view is the pinion extensions  10 , cable tie  17  that secure pinion extension  10  to front contact plate  2  and rear contact plate  3 , shown extending vertically from main frame  1  are front and rear contact plate guides, these allow vertical travel of the contact plates and keeps contact plates centered with main frame  1  these are bent upward by the use of a break press. Also in the case of a completely flat main frame  1  screws can be used as contact plate guides. This view also shows the side of the servo  7  and steering linkage rod  11 . The rear contact plate  3  shows the rear of the forward and reverse drive motor  6  and contact plate  3  and main frame  1  vertical guides.  
     [0014]FIG. 3 shows the front end of the frame set looking at it directly in front. In this view you see across the front the distance between the upright motors  5 , it shows the servo  7  in the center of the front contact plate  2 , and approximately how the main frame  1  vertical guides pass through the contact plate  2  also the coil springs  8  pinion screws  9  front wheel swivels  12  are shown in relationship to the front wheels  19  assembly. It also shows the front of the upright motor mounts  4 . View also shows the front of pinion nut connector extensions  16 .  
     [0015]FIG. 4 is a view of the rear of the frame set structure and it&#39;s components. It shows upright motor mounts  4 , upright electric magnetic motors  5 , rear contact plate  3  with drive train motor  6  mounted to it by axle and drive motor mount plate  13 . Pinion  14  engages with gear  15  to propel vehicle forward or in reverse. When motor is energized through wire or wireless battery powered remote control, mainframe  1  is shown from the rear with rear contact plate  3 , vertical main frame  1  guides also shown are pinion screws  9 , coil springs  8 , axles studs  18  and wheel  19  assembly.  
     [0016]FIG. 5 shows the pinion torque screw assembly. The pinion screw  9  is hollow in the pinion and has a threaded hole through one side so that when the pinion is slid onto the motor shaft it can be secured in place by use of a allen screw through the hole located in the side of the pinion screw  9 . The pinion nut connector extension  16  has a threaded hole through the center of it which facilitates vertical travel of the pinion nut connector extension  16  up or down the pinion screw  9 . When up right electric magnetic motor  5  is energized in a forward or reverse circular rotation, pinion extension  10  extends outward from the pinion nut connector extension  16 , and is mounted to the contact plates  2  and  3 , use of a cable tie  17 . This is the point at which energy from the motor results in the vertical raising or lowering of the main frame  1  structure.
