Description of drawings:

Accompanying drawing is the wheelbarrow structural representation.

Describe the utility model in detail below in conjunction with drawings and Examples.Accompanying drawing has provided a kind of optimum structure of the utility model, it is provided with wheel 20, wheel 20 is made of wheel spoke 4 and axle housing 8 and car band, settle open-work formula gear ring 3 on the wheel 20, this gear ring is similar to big internal gear, all is open-work with the root of inner gear different is each tooth, so appellation open-work formula gear ring, can make one with wheel spoke 4 during fabrication, also can make individual components and be embedded on the spoke 4.It must be slightly less than rim, and should be the individual very circle of standard.Owing to consider when on muddy highway, travelling to reducing muddy alluvial, so it is designed to the open-work formula.It is cantilever 2 that the center of wheel 20 is provided with sprung parts, cantilever 2 upper end holes and the crank shaft 7 concentric outer ends that are movably arranged on axle housing 8, the middle part of cantilever 2 is equipped with concentric circles gear 22, projecting shaft 1 is installed in the lower end of cantilever 2, coaxial V-type vehicle frame 11 and the external fan type gear 23 of being movably installed with successively on projecting shaft 1, what this also need further specify be, cantilever 2 is except linking wheel 20 and V-type vehicle frame 11, and it another mainly acts on just and just be that the two ends by it are that cantilever lower end axle 1 separates a segment distance with crank shaft 7 and V-type vehicle frame 11.Because the total weight of V-type vehicle frame 11 comprises that also human weight all acts on the cantilever lower end axle 1 when riding, and makes cantilever 2 vertical stem ground.V-type vehicle frame 11 front end bottoms are equipped with interior wing type gear 21, handlebar is installed in preceding upper end, elevating arc 21 engagements in above-mentioned concentric circles gear 22 tops and V-type vehicle frame 11 all-in-one-pieces, bottom and oppositely bar 19 lower end all-in-one-piece external fan type gears 23 engagements, V-type vehicle frame 11 retrodeviates the upper part anti-hypsokinesis eccentric gear 17 is housed, level is to slideway is installed on V-type vehicle frame 11 backs, limit spring 13 is installed in the slideway, limit spring 13 1 ends are fixed on slideway one end, the other end is fixedly mounted on the support unit of vehicle seat in the slideway, under the effect of spring 13, can make movable vehicle seat 14 levels to moving, the rear end of slideway is equipped with clothes hanger 16 with positioning pull bar 15, and external fan type gear 23 upper ends and anti-phase bar 19 fuse, and the anti-eccentric gear 18 that leans forward is equipped with in the upper end of anti-phase bar 19, in the axle housing 8 speed-changing mechanism is installed, the controller 12 of speed-changing mechanism is placed on the handlebar, and crank shaft 7 is installed crank 6, is provided with pedal 5, mudwing 10 is provided with car ladder 24 at V-type vehicle frame 11 rear lowers.

Principle of work: when V-type vehicle frame 11 recedes, be fixed point with V-type vehicle frame axle center, the camber line that is marked for moving point with vertical anti-hypsokinesis eccentric gear 17 axle center in the zone of regulation, all can with certain some intersection of open-work formula gear ring 3.That is to say, when vertical anti-hypsokinesis eccentric gear 17 along with V-type vehicle frame 11 access areas in during the crossplot point of two camber lines, the short radius of anti-hypsokinesis eccentric gear 17 will with 3 engagements of open-work formula gear ring, limit it and cross crossplot point, make V-type vehicle frame 11 no longer continue inclination.If this moment, wheel 20 was motionless, then V-type vehicle frame 11 is limited in the angle of inclination slack.As wheel 20 rotations forward this moment, so, vertically anti-hypsokinesis eccentric gear 17 will rotate along with the rotation of open-work formula gear ring 3, the radius of vertically anti-hypsokinesis eccentric gear 17 increases gradually in rotary course, driving V-type vehicle frame 11 returns to original position, until vertical anti-hypsokinesis eccentric gear 17 Rotate 180s °, radius be increased to the longest till.At this moment, V-type vehicle frame 11 is corrected to the upright position and promptly refers to tilt preceding position by receding, and vertically anti-hypsokinesis eccentric gear 17 also breaks away from fully with open-work formula gear ring 3, has realized vertical hypsokinesis balance.When leaning forward, the vertically anti-eccentric gear 18 that leans forward is installed in the upper end of reverse bar 19, just often is positioned at behind the V-type vehicle frame below the lower position; The following stomidium of reverse bar 19 and the hole and concentric, the coaxial connection of cantilever 2 lower end axles 1 three at V-type vehicle frame 11 tips.In addition, 22 centres that are fixed on cantilever 2 of concentric circles gear, interior wing type gear 21 engagements of this gear top and V-type vehicle frame one, bottom and oppositely external fan type gear 23 engagements of bar 19 lower end one.If V-type vehicle frame 11 turns forward, with the interior wing type gear 21 of V-type vehicle frame 11 one also along with rotating forward around axle 1, and turning effort is passed to concentric circles gear 22, and then drives the external fan type gear 23 with reverse bar 19 one.By the movement sequence transmission, when arriving reverse bar 19 upper ends, formed and the opposite rotation of V-type vehicle frame 11 direction of tilt.That is to say that when V-type vehicle frame 11 turned forward, oppositely bar 19 just receded, the two angle in swing is unequal, and direction is opposite.Along with V-type vehicle frame 11 angle that turns forward increases, make the short radius of the vertically anti-eccentric gear 18 that leans forward of reverse bar 19 upper ends press to open-work formula gear ring 3 and with its engagement, equally, also be that the vertically anti-eccentric gear 18 that leans forward rotates along with the rotation forward of open-work formula gear ring 3, until Rotate 180 °, radius is increased to the longest, promotes till reverse bar 19 return-to-home positions.At this moment, V-type vehicle frame 11 is corrected by turning forward gets back to the position of upright position before promptly referring to tilt, and has realized vertically leaning forward balance.Different is, the trimming process of the balance that vertically leans forward fails to finish by eccentric gear to vertical hypsokinesis balance correction is direct like that; But by the vertical anti-eccentric gear 18 that leans forward, finish by reverse bar 19, concentric circles gear 22 and interior wing type gear 21 and external fan type gear 23 indirect transfer.Simultaneously, clothes hanger 16, positioning pull bar 15, movable vehicle seat 14 and limit spring 13 can be as the balance adjustment parts in the relative static conditions, and the relative static conditions here is reference system with the wheel.These two parts all have independence separately, mutually noninterfere in the balanced system of wheelbarrow.The latter's balance adjustment, its purpose mainly are during for load weight on clothes hanger 16, can be by being the center of gravity of center-point with the movable vehicle seat on the V-type vehicle frame 11 14, and can be adjusted in time and be provided with.Therefore, no matter be static relatively or dynamically in, as long as there is weight of object to act on the clothes hanger 16, movable vehicle seat 14 all will be adjusted at any time passively, to keep the state of equilibrium in the static state relatively.Clothes hanger 16 is not having weight of object to do the time spent, elastic force by limit spring 13 is limited in movable vehicle seat 14 on the back-end location of slideway, human body optimum balance position when this is single riding, on this position, the center of movable vehicle seat 14 is an imaginary line in the perpendicular line back of crank shaft 7, the vertical center of gravity line that this perpendicular line is decided to be the balance in pitch of wheelbarrow meets relative static balancing condition.When the object of constant weight is pressed in above the clothes hanger 16, the rear end of clothes hanger 16 will be around the dead axle of front end to lower swing, the size of pendulum angle depends on weight of object and the elasticity of limit spring 13, the length between the moving axis from clothes hanger 16 front end dead axles to connection positioning pull bar in addition on the Coat hanger 16.Certainly, appropriate selection also is very important to the elasticity of spring 13.In addition, object is heavier, and the angle of clothes hanger 16 bottoms is bigger; The distance of translation is also bigger forward along slideway for movable vehicle seat 14, under the weight of object effect, promotes vehicle seats 14 along slideway translation forward, near the vertical center of gravity line of crank shaft 7 with clothes hanger front end bonded assembly positioning pull bar 15; While compression spring 13, after the elastic force of weight of object and compressed limit spring 13 was cancelled out each other, movable vehicle seat 14 stopped to move forward, and the vehicle seat position of this moment remains the optimum balance position in riding.In this process, the translation distance of the center maximum of movable vehicle seat 14 can overlap with the vertical center of gravity line sometimes, but can not cross the vertical center of gravity line.It retrains reason, because the people is when riding, and two hand steered firmly handlebars, upper body part turns forward, and a part of weight has wherein been pressed to handlebar, and handlebar is far away from the distance of vertical center of gravity line, can not cross the vertical center of gravity line so emphasize the center of vehicle seat.When car was parked, wheelbarrow can be supported not fall by car ladder 24; When single riding, do not become as the vehicle seat position, equilibrium conditions is not damaged; Then two eccentric gears all do not contact with open-work formula gear ring.Be the perfect condition in riding at this moment.In case this perfect condition was destroyed in moment, then will be proofreaied and correct automatically separately in the balanced system.That is to say, in the process of normally riding, the front and back immediate inclination is temporary transient, and stable state of equilibrium is lasting permanent, if people are through after the wheelbarrow exercise of riding over a long time, so, will be As time goes on, keep the balance in pitch state by the balanced system that depends in the car, progressively change adaptation self into and keep state of equilibrium, and the dependence of balanced system is also just dropped to bottom line.In order to allow the bicyclist can be according to the rational own muscle power of utilization of external condition, make the brisk comfortable top gear that then adopts when on smooth road surface, accelerating to ride, against the wind and on bridge, the laborsaving and stable bottom gear that then the adopts when deceleration of going up a slope is gone slowly.
