     FIELD OF THE PRESENT INVENTION 
     The present invention relates to circumferential movement, especially to all circumferential movement devices utilizing force of gravity, such as transport vehicles, toy vehicles, space vehicles, blenders etc. 
     SUMMARY OF THE PRESENT INVENTION 
     The object of the present invention is to provide circumferential movement devices with new structures and new driving methods, including vehicles with new structures and corresponding driving methods, braking methods and steering methods etc. The devices can utilize force of gravity sufficiently and shall be safe, saving and high efficient. The device can be used in all circumferential movement devices such as transport vehicle, toy vehicle, space vehicle and blender and so on. 
     The disclosure of this invention is introduced as following. 
     1. Integrated vehicle. The integrated vehicle includes wheels and vehicle body. The vehicle body can be shaped as cylinder, square or polygonal canister. The vehicle body shall keep a certain distance from the road surface so as to ensure the movement of the vehicle. Wheels are installed at the middle or two ends of the vehicle body and are rotated with the vehicle body at same time in movement. 
     Such vehicle may has one wheel and installed at the middle of the surface of the vehicle body; or such vehicle has one wheel only, the width of tire reaches to ⅓ of the width of the vehicle body or above; or the tire shall include tire and part of rim. Such tire shall include all kinds of tires of related technology. 
     The tire surface shall be in sufficient width to ensure the vehicle drives on road placidly. Or the whole vehicle is just a wheel. Or several wheels can be installed on the surface of the vehicle. 
     Or, two or two group wheels are to be installed at two ends of the vehicle body. The two ends of the body shall include the surfaces of two ends and the positions near the two ends. 
     One tire can be comprehended as one group tires, i.e. one tire can be substituted by two or above tires to play the role of one tire. Tire is installed on the body and is rotated with the body as well as the cargo inside the vehicle together. 
     The width of tire can be preset according to related technology. One tire can be comprehended as one group tires, i.e. one tire can be substituted by two or above tires to play the role of one tire. Tire is installed on the body and is rotated with the body as well as the cargo inside the vehicle together. 
     The wheel includes tire and rim; here, rim includes all parts inside the tire of the wheel. But, the wheel which is installed on the integrated vehicle shall have tire only, or has tire and part of rim. The vehicle body can replace part or all rim. The wheel may include tire and part of rim. 
     No driving force is needed when the vehicle drives downgrade, only the driving force greater than zero is needed when the vehicle drives on flat ground theoretically, when upgrade, more energy can be saved than other vehicles with related structure due to it can utilize the gravity force better. Such vehicle is comparatively suitable to carry water, oil, cement, sand, slurry, coal, and ore, etc, and there are inlet and outlet of cargo. 
     A trailer rack can be installed on the integrated vehicle to be used as a trail car, the integrated vehicle is rotated relative to the trailer rack on its axis, and the trailer rack connects with the motive vehicle, the trailer rack moves on by dragging of the integrated vehicle. The integrated vehicle can be used as boxcar of a train. Several integrated vehicle with the trailer tracks can be run as a train, such train shall at least include a head and several boxcars with trailer racks and pothooks, these boxcars move and be dragged by the head. 
     The integrated vehicle may be driven by the engines and transmission device with related technology. There is a trailer rack on the vehicle body, the trailer rack shapes as a frame and carries one or more trailer wheels. The trailer wheel adopts related technology. An engine is fixed on the trailer rack and a transmission device is fixed on the vehicle body to receive the transmission force from the engine. For example, a rubber roller with related technology transmits the driving force to the integrated vehicle; an electromotor is fixed on the top of the trailer rack, a rubber roller is on the axis of the electromotor, there is a rubber loop on the vehicle body to receive the friction from the rubber roller, the rubber roller drives the rubber loop and pushes the vehicle to move together. 
     Gear wheel or gear hole driving with related technology are also be available. China Patent application number 200410030581.x&lt;A Sort of Vehicle&gt;,  FIG. 54-59  shows a kind of gear hole driving. It is also available to adopt remote control method to operate the integrated vehicle—unpiloted driving. 
     2. Swing structure vehicle. The swing structure vehicle includes a vehicle body at least one wheel, and a swing bar for connecting the vehicle body and the wheel. There is an axis on the vehicle body and an axis at the centre of a wheel, one end of the swing bar connects with the body axis, the other end of the swing bar connects with the wheel axis. The body axis can also connect with the “dolly-car” at the bottom of the wheel, dolly-car “dolly-car” is attributed to a related technology and can be found in &lt;A Sort of Vehicle&gt;, China Patent number 200410030581.x, viz. a “dolly-car” in “large wheel driving method”. The vehicle body with swing structure is capable to match up the flirt of the wheel as like as pendulum and swing. As long as the barycenter of the vehicle body is not higher than the circle centre of the wheel, the swing structure can keep the vehicle in balance and stabilization. 
     The advantage of it can move the weight of the vehicle to the frontage of the gravity surface of the wheel and produce driving force. The position of the vehicle moves ahead can reduce the pressure to the vehicle body and change the force direction, to generate the component of forces and save energy. 
     The extent of swing can be controlled to keep it fore-and-aft, or only keep it go forwards, or limit the extent when it swings fore-and-aft: preset caging position on the body, swing bar or wheel, the caging device can be a stake, step or spring and set it at the side of swing bar, swing bar will be held up at a certain angle. 
     Another swing structure is use a swing bar with a bend and concave structure as a crank shaft in an internal-combustion engine to integrate with the axles of the body, swing bar and wheel within the swing structure. The vehicle body installs inside the concave and can swing fore-and-aft, more the space of the concave, and more the swing radius of the body. The sufficient wheel diameter in such structure is necessary to ensure the swing radius. 
     A swing bar can be a shaft, or a wobble tray. The wobble tray can be shaped like a circle or semicircle, or anomalous to play a role of swing bar. A swing bar can decline the barycenter of the body and increase its stability. 
     The stress point of the force of an engine can be at the wheel fringe. “Wheel flange transmission” and “large wheel transmission” with related technology can be driven on the top of a wheel, refer to China Patent application 200410030581.x&lt;A Sort of Vehicle&gt; for details of “Wheel flange transmission” and “large wheel transmission”. The vehicle body can be dragged as like as a trailer car, the body drives the swing bar, the swing bar drives the wheel and push the vehicle moves on. 
     3. Eccentric swing structure—the diameter of the vehicle body axis is smaller than that of axis hole of the wheel at the circle centre. In other words, the diameter of the wheel axis hole at the circle centre is greater than that of the vehicle body (the vehicle body axis here can also be swing bar axis). The body axis connects with the wheel axis hole and be located at the fringe of the bottom of inner loop of the axis. The body axis can change its position in the axis hole when in movement, it can be departed from the gravity surface and swing to the direction of forward, thus, the gravity force changes to the driving force. 
     Axis hole means the hole at the inner loop of the axis. The connection method between the vehicle body axis and the axis hole can use related technologies as welding, affixing and covering. The method of covering: connect the vehicle body axis with the inner loop cover which matches up to the inner loop of the axis hole, the inner loop cover shapes like a round cake, and fix it into the inner loop. The vehicle body axis is located at the fringe of the bottom of inner loop of the axis, i.e. the bottom fringe of the inner loop. 
     Such structure is “eccentric swing”, or “eccentric axis”. Eccentric swing can be used in the connection of swing, also can be used in all circle movements except the swing connection, e.g. wheel axis, to save energy by its gravity force. 
     4. Coaxial vehicle—also can be named as “two-wheel gravitational vehicle”, “two-wheel vehicle” or “sole-wheel vehicle”. A coaxial vehicle can has two or two group coaxial wheels which are located in the two sides of the body or bottom. Wheel runs relative to the vehicle body, and engine installed on the vehicle body be regarded as the passenger seat. The wheel of coaxial vehicle in this invention contains the wheels with same axial direction. Coaxial means two or two group wheels share with same axis. Same axial direction means two or two group wheels with different axes are within the same straight line and same axial direction. Two sides as above said means the surfaces of two profiles of the body and the positions near to the two ends of the body. 
     An axis at the circle centre of the wheel connects with the vehicle body, wheel runs relative to the body, the body does not rotate. The wheel of coaxial vehicle can be larger; its diameter is similar with the height of the body. A distance of wheel radius shall keep from the ground to convenient to design sufficient space and height for the vehicle body; the vehicle body does not touch the ground when it in swing. Such vehicle may carry an anchoring plate which can be ascending and descending to act as a brake. 
     A coaxial vehicle may have only one wheel; such wheel is rather wide and is located at the bottom of the body. The vehicle body connects with the wheel axis and is located on the top of the wheel. “Large wheel transmission” can also be adopted to connect the vehicle body with a “dolly-car”. 
     A coaxial vehicle contains the wheels with the same axial direction. The wheels with the same axial direction can be in different axial positions, i.e. the wheels with the same axial direction can disposed at front and rear positions, not in a same straight line. Such structure can increase the stability of the vehicle body, but the utilization of the gravity force is not so good. 
     There are engine and transmission device on the vehicle body, the method of the impetus transmission: transmit the engine driving force to the position on the vehicle body above the wheel first, then transmit to the top fringe of the wheel and drive the wheel running. Or, transmit the strength of human to the top position of the wheel of the vehicle body first, then drive the wheel. For example, lay an electromotor on the top position of the wheel corresponding to the body, by transmission device or rubber roller, the engine drives the wheel running. Other methods also can be adopted, such as to use wheel engine to drive. 
     In the structures as described above, an electromotor can also be laid at the bottom of the vehicle body, by transmission device, to transmit the engine driving force to the wheel. It is better to dispose the human, cargo and the vehicle facilities to the bottom of the body to decline the gravity centre and ensure the stability and utilize the gravity force perfectly. 
     It is also possible to lay the barycenter of the vehicle body on the circle centre of the wheel so as convenient to use swing structure; such structure shall be equipped with a supplementary wheel. Such supplementary wheel shall be installed at the front or rear position of the vehicle body and to play a balance role and prevent the overturn of the vehicle body. Such vehicle belongs to “multi-wheel vehicle”. 
     To drive a coaxial vehicle by human power, it is only need to transmit the human power to the top of the wheel to realize “wheel flange transmission” or “large wheel transmission” by related technology. For example, by a chain and a gear of bicycle, or transmission shaft and gear, or industrial strap and strap wheel, etc, to transmit the human power to the stress point on the top of the wheel to complete the transmission by human power. The driving of engine can also adopt above structure. 
     The differences of this structure with &lt;A Sort of Balanceable Vehicle&gt; of patent No.: 200310112992.9 are the driving force and transmission method. This structure provides with a technical resolution of engine driving, transmit the driving force of the engine or human power to the top or the fringe of the wheel, sufficiently use gravity and belongs to “wheel flange transmission” or “large wheel transmission”. 
     The stress point of “two-wheel vehicle” is same as the force point of a lever and stress the strength to the top of the wheel; the position wheel touch the ground is same as the pivot of a lever, the pivot is at the ground; the weight of the body is at the circle centre or at the bottom of the wheel, is same as the stress point of a lever at the circle centre or the bottom of the wheel, such structure matches up the 3rd law of Circumferential Law, the energy and power can be saved. The weight of the body (include passenger and cargo) is disposed at the bottom of the body, by the role of swing, half and more gravity can change to driving force and therefore save power and energy. 
     The driving force of an engine stresses on the top of the wheel by the top of the vehicle body, the top of the wheel produces a counter force to the top of the vehicle body, the bottom of the vehicle body will swing by the leverage, in this way, most of the gravity of the body will transmit to the front of the gravity surface of the wheel, i.e. to the forward direction, more than half of gravity of the vehicle becomes the driving force to drive the wheel. 
     Compressed air can also be used as the driving force, there is a huff nozzle on the top of the vehicle body, the baffle plate, or lamina, or a concave around the wheel will receive the puffing air, puff the air to the top of the wheel to drive the wheel running by the counter force of puffing air. To use compressed air as the driving force can be adopted according to related technology. 
     An jet engine can also be installed on the vehicle body such as the jet aircraft and jet car, to puff the air forward the rear of the body and drive the vehicle running and as well as compressed air. 
     The compressed air tank and engine can fixed in the wheel and run together with the wheel, air switch controls the huff nozzle, huff the air backward when the wheel rotate to the peak and drive the vehicle go forward. Huff will halt when the wheel is over the peak. 
     The compressed air tank shapes like circle pipe or round cake which is suitable to the shape of tire, it shall be installed the steel rim or the position with the same axial direction outside the wheel. There are several huff nozzles with the valves around tank, the valves shall open only the wheel runs to the peak position and drive the vehicle forward. 
     The structure of huff switch: there is an elastic cover on the huff nozzle on the wheel, the cover can run around the axis, a baffle plate at the peak position of the wheel, when one huff nozzle runs to the peak position, baffle plate pull out the elastic cover and the high pressure air huff burst out to produce thrust. The elastic cover closes again when the nozzle runs over the baffle plate. Next nozzle will repeat the above movement. Baffle plate can be fixed on the wheel axis. 
     The second structure of huff switch: there is an elastic piston at the huff nozzle; the piston connects with a pull staff, the pull staff runs around the axis, and there is a baffle plate at the peak position of the wheel, when one huff nozzle runs to the peak position, baffle plate pull out the pull staff of the piston and the high pressure air huff burst out to produce thrust. The elastic cover closes again when the nozzle runs over the baffle plate. Next nozzle will repeat the above movement. Baffle plate can be fixed on the wheel axis. 
     The third structure of huff switch: there is a magnet at the position of baffle plate, when a huff nozzle runs to the peak position, the attraction of the magnet opens the elastic switch, high pressure air huff out and produce thrust, the elastic cover closes again when the nozzle runs over the baffle plate. Next nozzle will repeat the above movement. Baffle plate can be fixed on the wheel axis again. 
     The huff nozzle can be controlled by automobile and all related technology, such as gas jet control technology of internal-combustion engine, ignition technology and touching-switch technology, etc. all related technology can be adopted. 
     The intermittent blowing, or stroke blowing can also be adopted, blow the air at each interval, e.g. per second. Continuous blowing produces smaller inertial counter force, while intermittent blowing can increase counter force and enhance the effectiveness. Of cause, the air-powered engine with related technology can be adopted as the impetus for this vehicle. 
     5. Multi-wheel gravity vehicle—means the gravity vehicle with two or more wheels. There are two coaxial wheels on multi-wheel gravity vehicle, including front and rear supplementary wheel. The supplementary wheel are installed at the front and rear of the body to play the role of auxiliary movement, balance and stability, furthermore, equipped with the flex function upward and downward as well as the function of universal wheel. Automobile and train with related technology can be changed to multi-wheel gravity vehicle. Any vehicle adopts the swing connection and/or eccentric swing structure of this invention can also use “wheel flange transmission” or “large wheel transmission”, which is a kind of multi-wheel gravity vehicle. The diameter of the wheel of this kind vehicle is rather small and can be similar or same with the wheels of the vehicles with related technology. 
     For example, a car with related technology has four wheels, change wheels into swing connection, or only change the rear two wheels into swing connection, adopt “wheel flange transmission” or “large wheel transmission”, the impetus of engine stresses on the top of the wheel and the top of the wheel produce a forward counter force to the body, more than half of the body weight changes to impetus and together with the engine power to drive the vehicle. 
     For multi-wheel vehicle, each wheel can connect with the body swing, or only part of wheels connects with the body swing, e.g. only two rear coaxial wheels in a tricycle connect with the body swing, the front wheel does not. Both multi-wheel and dual wheel gravity vehicles adopt Circumferential Law to utilize gravity. 
     If adopt small wheel, the radius of the wheel is small accordingly, the vehicle body shall near to the ground and also less the swing extent of the body, this problem can be resolved by related technology “large wheel transmission”. Connect the body with the small swing in large wheel, there is a rack on the “dolly-car”, the rack can be same height with large wheel or higher. Because the “dolly-car” rack moves relative to large wheel, so the rack may higher than large wheel. Once such body connects with the dolly-car rack which height has been added, the swing extent can be greater. In this case, swing position limit is necessary to avoid the overturn of barycenter. Such structure is available to dual-wheel vehicle too. 
     “Dolly-car” can be substituted by a large bearing, that means the diameter of the bearing hole is greater than body axis, eccentric swing also adopt this kind of bearing. Bearing ball is equal to the wheel of a “dolly-car”. The body axis connects with the internal loop of the bearing as the method foresaid. Actually, such structure is a “large wheel transmission”. This invention can be adopted by a quadricycle with related technology, use swing structure and regard the front two or rear two wheels as the driving wheels and driven by the engine. Another two wheels adopt large bearing structure as above said, dragged or pushed by the driving wheels. This is also a kind of gravity and such technology can be adopted by any vehicle with related technology. 
     The technical classification of any integrated vehicle, swing structure and multi-wheel vehicle included in this invention is purposed to describe clearly and easy to comprehend, not mean that such technology should be used solely or synchronously. In practice, all technical resolutions and features in this invention can be utilized solely or synchronously and suitable to combine with related technology. 
     Any non-impetus vehicle, such as train carriage and trailer car, also can accept such eccentric axis and/or swing connection, when an external force draw the vehicle body, the body swing to the forward direction and get over the gravity surface of the wheel, such gravity changes into impetus, thus can save more energy to draw the vehicle. Eccentric axis can be used in all circumferential substance movement. Any wheel with related technology can adopt such structure. 
     6. Quadricycle—has two or two group coaxial wheels as main wheels, main wheels are located at the middle bottom of the body. A supplementary wheel is also carried. The supplementary wheel is installed at the front and/or rear part of the body. The main wheels play the roles of loading, driving, braking and turning. The coaxial wheels as foresaid include the wheels with the same axial direction. The coaxial means the same axis shared by two or two group wheels, and the same axial direction means two or two group wheels with different axes but located in the same straight line and same axial direction. 
     For example, main wheels have two coaxial wheels and located at the middle of the body, one supplementary wheel each at the front and rear part of the body, four wheels shape like diamond (rhombus). Main wheels play the roles of loading, driving, braking and turning, these functions can realized by related technology; e.g. only drive or brake one of main wheels, the vehicle can turn the direction; only brake one of main wheels in movement, the vehicle can make the round in same place and consume inertia energy to play the role of braking. Of cause, it is possible to brake the wheels at same time. Weight or the gravity of a vehicle, mainly is borne by main wheels, so as to utilize the gravity. 
     Supplementary wheel plays the role of stability and balance, avoid the body to touch the ground in movement, keep stability in braking; supplementary wheel can perform the feature of anchoring plate, to bear part of load when the front or rear part of the body receive the pressure downward, the above said roles can be played when the vehicle in movement or in braking. Supplementary wheel connects flexibly with the body and can turn in parallel follow the body turning. Supplementary wheel can adopt universal wheel structure with related technology. Supplementary wheel carries an elastic device and be equipped with elasticity except the elasticity of tire, it can flex follow the pressure. In running, main wheels touch the ground while the supplementary wheel is unnecessary to touch the ground or slightly touch, or touch the ground in discontinuity; or, only one supplementary wheel touch the ground in running, or only one supplementary wheel slightly touch the ground or touch the ground in discontinuity. Of cause, there are two supplementary wheels each to be installed at the front and rear part of the body, there are four supplementary wheels in total. In this way, there are six wheel, two main wheels and four supplementary wheels. The number of supplementary wheel can depend on situation. 
     This invention adopts the liquid wheel in the Patent application 200410030581.x&lt;A Sort of Vehicle&gt;, the smaller the touchdown radius of the liquid wheel, the less the resistance. A light jelly, cream or semiliquid, the kind such as like as “aerogel” can be filled in liquid tire. Aerogel is a kind of jelly with light quality; it can transmit pressure in tire according to Pascal&#39;s Law. 
     One of the advantages in this invention is energy saving, i.e. to sufficiently use own weight by the structures of the gravity vehicle and swing connection designed by Circumferential Law, to realize the purpose of power and energy saving. A combination of eccentric axis and swing connection can save more energy. The second advantage is the structure of all vehicles is much more simple and reasonable than described in related technology. The third advantage is there is a new structure produced by dual-wheel and multi-wheel gravity vehicles and provide with more options. The fourth advantage is the wider applicability, available to all circle movement devices, such as human powered vehicle, motor vehicle, toy vehicle and space vehicle. The fifth advantage is safer by using of new braking method and new structure, avoid overturn due to its gravity declines and enhance its security in braking. The sixth advantage is cost reducing, due to the structure is greatly simplified, the manufacturing cost reduced. Moreover, the energy can be saved greatly during movement; therefore, not only decline the operating cost, but also benefit to the protection of global resources. The advantages of this invention are also specified in the relevant contents in the whole text.

     DETAILED DESCRIPTION OF THE INVENTION 
     FIG.  1 —Circumferential substance  1  can be a ball, or a cylinder, or a wheel and located on the load surface  3 . Its weight surface  2  is located at the center of the circle. The weight surface  2  is fictitious, but the interface of the weight is in objective reality. A circumferential substance touch with the load surface can not but produces a weight interface, i.e. the weight interface. At both sides of the weight surface  2 , the weight sizes are equal, directions are contrary. Although the weight is downward, but the both sides of the weight surface of the circumferential substance will produce two equal weights, their directions are contrary. The load surface includes the ground. If a perfect point or line of the circumferential substance touch with the firm load surface, whether different in their quality, the force to overcome the static inertia is greater than zero. The movement rule will follow Circumferential Law as foresaid in this article. This point is absolutely contrary with the Newton Law, which means Newton Law is not applicable to circumferential substance movement. It will be alternatively between us! 
     FIG.  2 - 3 —Wheel  101  is circumferential substance and connects with swing bar  4  at the place of wheel axis  5 , body axis  6  is at the swing bar  4 , and it is used to connect with vehicle body. When swing bar  4  in the figure moves to the left side of the weight surface  2 , the body weight will produce the gravity to the wheel  101  lean to the left side, this gravity will become the forward impetus. The circumferential substance  101  can act as the wheel for the wheels of all vehicles including train, automobile, trail car and human powered vehicle. 
     FIG.  4 —Wheel here is omitted, there is a limit stake  8  on the body  7 , limit pole  10  on swing bar  4 , limit stake  8  and limit pole  10  can be used alternatively or synchronously. Besides, limit spring can be used also. They can play the role to limit the body swing on the wheel within a certain extent. The ratchet structure with related technology can also be available to limit the swing forward only. 
     FIG.  5 - 6 —Wobble tray  401  or  402  on the wheel  101 , there are several structures for swing bar,  401  and  402  is the swing bar with different structure and with the same function of the swing bar  4  in  FIG. 3 . Wobble tray  401  shapes like flat plate or a round flat plate, a piece was cut off on the top in the figure. The geometry shape of a swing bar can be changed except its function of swing bar. The role of a swing bar is to connect the body and wheel and swing the body relative to the wheel. A swing bar has other functions, such as to carry a limit device. Wobble tray  402  is also equipped with the function to increase the swing extent. There is body axis  601  on the wobble tray  402 ; it expresses that to move the body axis from the underside of the circle center of the wheel to the upside, even higher than the wheel. As long as the gravity of the body not exceeds the circle center of the wheel, the body can not be overturn. But in multi-wheel vehicles, the gravity of the body can exceed the circle center of the wheel due to the balance of the supplementary wheel; the vehicle body can not be overturn. 
     FIG.  7 - 9 — FIG. 8  is the inner loop cover;  FIG. 9  is a left-view diagram. There is inner loop cover  11  in inner loop  13  of the bearing  100 , cover hole  12  on the inner loop cover  11 . Inner loop cover  11  is fixed on the inner loop cover  13 . Bearing  100  is installed on the wheel; bearing ball and inner loop  13  are similar with the “dolly-car” in large wheel transmission device. The body axis is fixed in the cover hole  12 , equals to connect with inner loop cover  13 . The body axis can be fixed on the inner loop by welding, covering or affixing, the figure displays the method of covering. In movement, the body axis can pull inner loop  13  to a certain angle and keep the body axis away from the weight surface of the wheel, i.e. swing the body relative to the wheel and change the gravity to forward impetus. 
     FIG.  10 —The vehicle body  16  combines with the wheels at its two sides and becomes an integrated vehicle  18 . the body and wheels shape round, the left-view and right-view diagrams show a small round in a larger round, so the left-view and right-view diagrams was omitted. The diameter of the body is smaller than the wheel and keeps a certain distance from the ground to ensure the movement. The body runs following the wheels. The integrated vehicle can be used to carry cargo, such as coal, ore, petroleum and gluewater, etc. the integrated vehicle. There is no inlet or outlet as well as the inspection opening for cargo in the integrated vehicle, just like a tank truck. An integrated vehicle can carry roller  14 , the trailer and vehicle tracks can be installed on it to control the movement of the vehicle.
