Description

Automatic cart

The utility model relates to a kind of power car, particularly two-wheel power vehicle.

Existing two-wheel car has bicycle, motor bike etc., the former steps on the Lixing by pedaling of people and sails, and its speed is slow, wastes time and energy, the latter travels by the fuel start the engine, its cost height, complex structure, big energy-consuming, also has a kind of electric bicycle at present, as power, cost is also higher by storage battery for it, also needs often charging.

The purpose of this utility model is exactly to provide a kind of simple in structure in order to address the above problem, and cost is low, and speed is fast, the self-moving vehicle that travels by natural force.

Technical solution of the present utility model:

A kind of self-moving vehicle, it includes tap 1, front-wheel 2, trailing wheel 3 and car body 4, the wheel rim that it is characterized in that front-wheel 2 steel rings has at least a side to be provided with a circle annulus tooth 5, and the crown of annulus tooth 5 does not exceed the outer rim of front-wheel 2 steel rings, one circle groove 6 is respectively arranged at the middle part on two surfaces of steel ring of front-wheel 2, top in the grooves on two sides 6 at least respectively is provided with two antifriction-bearing boxs 7, the inner ring of each antifriction-bearing box 7 is fixed in respectively on the pivot pin of front-wheel baffle plate 8 homonymy inwall relevant positions, make the outer ring of each antifriction-bearing box 7 and ball thereof can be in grooves on two sides 6 positioning and rolling, make front-wheel 2 be eccentric wheel; At least side by side flexibly connect a bidentate wheel shaft 9 in the bottom of leading 1 straight-bar, the lower end of bidentate wheel shaft 9 is connected with the annulus tooth 5 of front-wheel 2, its upper end is connected with flywheel 11 between the front and rear wheel 2,3 by straight-bar axle 10, and the clutch transmission that flywheel 11 passes through on its center shaft is connected with trailing wheel 3.

The utility model utilizes small friction force to obtain bigger torsional forces and centnifugal force makes body movement, need not to consume any fuel or electric power, its dependable performance, easy to use, laborsaving saving time, safe and reliable, speed improves greatly than bicycle, can reach 40 kilometers/hour, can replace Bicycles and Motorcycles etc., the utility model is simple in structure, produce easily, cost reduces, and has made full use of elemental effect, the mankind progressively break away from rely on the realm of nature energy aspect stepped major step.

Further describe below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the power connection structure master of the present utility model scheme drawing of bowing.

As Fig. 1,2, be connected the bidentate wheel shaft 9 of leading 1 straight-bar bottom, its lower end installs annulus tooth 5 engagements of a straight gear 12 and front-wheel 2 steel ring outer rims one side, its upper end installs a crowngear 13, be connected to universal-joint 14 on the top of straight-bar axle 10, crowngear 13 engagements of crowngear 15 and bidentate wheel shaft 9 upper ends also are equipped with in the termination of universal-joint 14, and the lower end of straight-bar axle 10 also is equipped with crowngear 16, and it meshes with crowngear 17 on flywheel 11 center shafts one side.Clutch transmission on flywheel 11 center shafts can fixedly miniature gears 18 and the axial movable block 19 of afterbody helical teeth be formed by head, the axial movable block 19 of helical teeth rotates with flywheel 11 center shafts, and can be on flywheel 11 center shafts axial motion, it is connected with clutch handle 24 by steel wire 20, and its inner side end is against and recovers on the spring 21, and the fixedly miniature gears 18 of clutch transmission is connected with moment of torsion big gear wheel 23 on trailing wheel 3 wheel shafts by chain 22.Clutch transmission also can fixedly bevel pinion and the axial movable block 19 of afterbody helical teeth be formed by head, moment of torsion umbrella shape big gear wheel correspondingly is housed on trailing wheel 3 wheel shafts, and the straight-bar axle that has a crowngear that is meshed by two ends between the moment of torsion umbrella shape big gear wheel on the fixedly bevel pinion on flywheel 11 center shafts and trailing wheel 3 wheel shafts connects as one.Working process of the present utility model is as follows, earlier clutch clutch handle 24 with hand, by steel wire 20 with axial movable block of the afterbody helical teeth of clutch transmission 19 and fixedly miniature gears 18 disengagements of its head, recover spring 21 and be compressed this moment, like this, driving force on the front-wheel 2 is not delivered on the trailing wheel 3, and flywheel 11 is still rotatable, promote car body 4 then forward, because the tire 25 of front-wheel 2 and the effect of ground-surface little coefficient friction force, front-wheel 2 is rotated forward, then one of its steel ring wheel rim side circle annulus tooth 5 rotates the crowngear 13 of bidentate wheel shaft 9 upper ends by the straight gear 12 of bidentate wheel shaft 9 and its lower end, the crowngear 15 that its rotation is connect straight-bar axle 10 upper end universal-joints 14 rotates, universal-joint 14 is used for making straight-bar axle 10 to rotate synchronously with tap 1, and like this, the crowngear 16 of straight-bar axle 10 lower ends also rotates simultaneously, it to the crowngear 17 on flywheel 11 center shafts one side, and then rotates flywheel 11 transmission of power.Because front-wheel 2 is not established center shaft, only in the groove 6 of front-wheel 2 steel ring both side surface, respectively adorn two antifriction-bearing boxs 7, with they fulcrums as front-wheel 2, make front-wheel 2 be eccentric wheel, simultaneously the antifriction-bearing box fulcrum of these both sides is again as the lever moment of torsion fulcrum of front-wheel 2, so as long as there are some friction force on front tyre 25 bottoms and ground, just the position between two antifriction-bearing boxs 7 from the annulus tooth 5 of front-wheel 2 steel ring outer rims one circle obtains bigger torsional forces, pass to the straight gear 12 of bidentate wheel shaft 9 lower ends, bidentate wheel shaft 9 is given flywheel 11 by straight-bar axle 10 with transmission of power again, like this when front-wheel 2 rotates a circle, flywheel 11 has rotated multi-turn, can produce bigger centnifugal force again, can unclamp clutch handle 24 this moment, the axial movable block 19 of afterbody helical teeth that makes clutch transmission under the effect that recovers spring 21 with its head fixedly bevel pinion 18 connect as one, flywheel 11 just all passes to trailing wheel 3 with big torsional forces and the centnifugal force of itself that front-wheel 2 minimal friction produce by chain 22 like this, driving trailing wheel 3 rotates, the rotation of trailing wheel 3 travels forward car body 4, in the 4 proal whiles of car body, the big torsional forces that front-wheel 2 constantly will be obtained with the ground minimal friction again constantly adds to trailing wheel 3 together with the centnifugal force of flywheel 11, and the propulsive effort of trailing wheel 3 losses is less, thereby has guaranteed car body 4 fast automatic travelling.If when needing to slow down, can clutch clutch handle 24 again, the portion end to end of clutch transmission is thrown off, this moment, trailing wheel 3 just can not get torsional forces and the centnifugal force that front-wheel 2 and flywheel 11 provide, and car body 4 travels forward by the force of inertia of itself, falls speed, during if will stop, only need clutch brake crank and get final product.
