A kind of advantageous effect of above-mentioned vehicle using gravity drive is：

The first, the car wheel structure for the vehicle being nested by using scroll wheel 1, support wheel 2 and carrying roller 3, can make vehicle Load all be controllably converted into vehicle traveling power；The second, by reducing the deformation of scroll wheel 1, contribute to energy saving；The Three, by changing the type of drive of wheel, the driving effect of wheel can be improved；4th, by using scroll wheel 1 and carrying roller 3 are nested so that the dynamic equilibrium problems of vehicle can be resolved；5th, pass through the first lever assembly 43 of forward drive device 4 Or the second lever assembly 53 of reverse-drive device 5, using lever principle passing power, finally by power transmission to forward gear 44 or reverse-gear 54 on, gear 45 is altered course by advance or reversing changed course increment continues to transmit, so that foreign steamer 11 rolls It is dynamic；The curved rod of the curved rod of first lever assembly 43 or the second lever assembly 53 is arranged in the downside of 31 end of lubrication groove Wheel 31 rolls reverse position so that foreign steamer 11 is easier to roll；The structure design of the present invention is simple, can realize and be turned using gravity The power of wheel rolling is turned to drive vehicle, and then is realized energy saving.

It is described as follows by the advantageous effect of foregoing description：

The first, the car wheel structure for the vehicle being nested by using scroll wheel 1, support wheel 2 and carrying roller 3, can make vehicle Load all be controllably converted into vehicle traveling power, while by reduce scroll wheel 1 deformation, contribute to energy saving.

The moiety by weight that carrying roller 3 is shared can be oppressed all in the first curved rod or the second curved rod and support wheel 2, be led to It crosses under advance pedal 41 or reversing pedal 51 and steps on degree, distribution of the weight in the first curved rod and support wheel 2 is shared in regulation and control Ratio or the allocation proportion in the second curved rod and support wheel 2 realize forward drive device 4 or 5 counterweight of reverse-drive device Power is converted into the adjusting of the power of vehicle traveling.Risen by controlling the first lever assembly 43 or the second lever assembly 53, at this time Start to oppress the first curved rod or the second curved rod positioned at the lubrication groove 31 of middle wheel 21, the size of oppressive force here is equal to carrying roller The size of 3 gravity jacked up, therefore under the action of lever principle, realization transfers force to forward gear 44 or reverse-gear On 54, gear 45 is altered course by advance or reversing changed course gear 55 continues to transmit, and then realizes the rolling of foreign steamer 11, realizes vehicle Load be controllably converted into vehicle traveling power.

The second, by reducing the deformation of scroll wheel 1, contribute to energy saving.

According to the origin cause of formation of force of rolling friction, force of rolling friction is mainly derived from the power overcome when rolling needed for deformation, certainly Also other atomic small power are opposite to inflate for wheel such as the molecule suction between contactant, if foreign steamer 11 uses change The minimum steel wheel of shape can reduce it and be in contact between ground along the length of rotating direction, when so as to shorten wheel rolling Fulcrum and wheel center of gravity spacing, accordingly reduce the arm of force of required torque when wheel rolling, it is identical in load-carrying, So that the torque needed for wheel rolling is reduced, and then reduce the power needed for vehicle advance, plays energy-conserving action.

As shown in fig. 6, to allow loading is the larger pneumatic tire uniform roll of M deformation, required torque is M × AB, and Loading is allowed to be the steel wheel uniform roll of the micro- deformation of M, required torque is M × CD, then F₁× OA=M × AB, F₂× OC=M × CD estimates so that wheel footpath is 60 centimetres of car wheel as an example, is substantially the inflation of most cars to the result that car observes and measures Wheel AB is about 10 centimetres, and OA is about 29 centimetres, and steel wheel hardly deforms, but here the OC of steel wheel in terms of 29.5 centimetres, CD In terms of 2 centimetres, then F can be found out₂For 19.66% F₁, the distance that one week exercises that turns a wheel is the same for S, and two power Work done very different, respectively F₁× S and F₂× S then illustrates one week required energy of vehicle wheel rotation also very different, steel Wheel only needs the energy of inflation wheel 19.66%, shows to realize significantly energy saving, section as the wheel that vehicle travels using steel wheel It can reach 80.34%.Certainly this energy saving be built upon puts aside steel wheel too and can increase firmly that wheel jolts the premise of energy consumption Under, but it is this significantly energy saving much larger than energy consumption of jolting.

Third, the type of drive by changing wheel, can improve the driving effect of wheel.

Wheel is changed into core wheel driving in the driving of the lateral margin of wheel advance side position, to increase driving force relative to vehicle Wheel rolling fulcrum presses the arm of force, to save power energetically, reaches energy saving purpose；Become the rolling of wheel to press, both into one The frictional force that step reduces wheel plays energy-conserving action, and can reduce floaing for vehicle in 11 advanced side of foreign steamer, one lower pressure of generation It is floating, also wheel is made not depend on frictional force and roll play the role of it is anti-skidding.

4th, it is nested by using scroll wheel 1 and carrying roller 3 so that the dynamic equilibrium problems of vehicle can be resolved.

When driving is set to the lateral margin driving of the advance side position of wheel, the normal rolling balance of wheel can be by broken It is bad, so as to cause the bounce or shake of vehicle, rolled, simultaneously when taking to add a wheel and be sleeved in power-actuated scroll wheel 1 When the chassis 8 of vehicle is erected on the wheel added, the weight of vehicle is also undertaken by the wheel added, the wheel added just at For carrying roller 3, and the circumference stress of carrying roller 3 mutually balances, then carrying roller 3 tends to put down along the interior side roll of scroll wheel 1 Surely, to make the traveling of vehicle reach plateau.

Further, further include brake 6 in a kind of above-mentioned vehicle using gravity drive, the brake 6 includes disc brake 61 and gravity brake 62；The disc brake 61 includes brake disc 611 and braking clamp 612, and the brake disc 611 is arranged in foreign steamer 11 On end face, the braking clamp 612 is arranged on the chassis 8；The gravity brake 62 includes brake lever 621, brake pedal 622, horizontally disposed compression bar 623, elliptic wheel 624 and reversing bar 625, the brake lever 621 are arranged under brake pedal 622 Side, one end of the compression bar 623 and brake lever 621 connect, and the other end is pressed against on elliptic wheel 624, a left side for the elliptic wheel 624 End face with it is described reversing bar 625 right side connect, it is described reversing bar 625 be arranged reversing pedal 51 lower section and with move backward pedal 51 connections.

Seen from the above description, when brake 6, brake pedal 622 is stepped on, 61 line of disc brake is tightened up, and braking clamp 612 clamps brake Hull 611 rolls to prevent foreign steamer 11, allows vehicle deceleration or parking.Brake 62 by the way that gravity is arranged, under touch on the brake pedal 622 so that the compression bar 623 for being connected to 622 lower section of brake pedal also declines therewith, since compression bar 623 is pressed against on elliptic wheel 624, Compression bar 623, which pushes, drives elliptic wheel 624 to decline, and then the reversing bar 625 being arranged below elliptic wheel 624 is driven to decline so that The reversing pedal 51 of reverse-drive device 5 is in down the state of stepping on, when compression bar 623 slips over the long axis end of elliptic wheel 624, compression bar 623 then no longer drive elliptic wheel 624 to decline, and reverse-drive device 5 resets and is no longer participate in brake 6, and then realize of short duration fall Vehicle effect auxiliary brake 6.
