The body structure of the technical program (Figure 10): bicycle wheels is driving wheel, vehicle frame is a trapezoidal shape, the vehicle frame middle part is provided with two trivet muscle, the vehicle frame front end is provided with a standpipe, settling front fork in the standpipe, the structure of halter and front fork is identical with ordinary bicycle, the front fork end is connected with the driving wheel wheel hub, at the cross member of frame forebody, be provided with the bench of taking for the fore rider pedestrian, the bench back is provided with backrest, the backrest back also be provided with for after the Double armrest that the people uses of riding, at the afterbody of cross member of frame, be provided with for after the bench that the people takes of riding, the back vent below the back bench is connected with trailing wheel.
Driving wheel wheel hub transmission principle is shown in (Fig. 7):
As figure when step (1) when stepping on, fixedly big gear wheel (10) drive support gear (38) is made backward rotation.And pass through bearing pin (27) drive satellite gear (26) around fixed gear shaft (40) rotation, do the anti-phase running of high speed thereby drive solar wheeling tooth wheel seat (37).Because solar wheeling tooth wheel seat (37) counter-rotating, the click (29) on handle ratchet wheel external gear this moment (28) is inoperative.So handle ratchet wheel external gear (28) is gone up at solar wheeling tooth wheel seat (37) and is slided.Simultaneously, solar wheeling tooth wheel seat (37) drive activity dual gear seat (11) is done the forward running, under the effect of ratchet, ratchet (13), handle ratchet wheel external gear (12) and movable dual gear seat (11) run-in synchronism have just driven inner gear shaft bowl (34) and have made the forward high-speed operation.This is the fast shelves of bicycle, and this moment, the speed ratio of wheel and step was 2.5:1.
When counter the stepping on of step (1), the click (13) on the handle ratchet wheel external gear (12) is inoperative, slides so handle ratchet wheel external gear (12) is gone up at movable dual gear seat (11).On the contrary, this moment the solar wheeling tooth wheel seat (37) clockwise, handle ratchet wheel external gear (28) under the effect of click (29) with solar wheeling tooth wheel seat (37) run-in synchronism, just drive inner gear shaft bowl (34) and make the forward low-speed running.This is the slow shelves of bicycle.This moment, the speed ratio of wheel and step was 1:1.
Have only fast shelves and a slow shelves two-stage speed change in the utility model.Can do you when riding, think that number of steps of speeds has lacked a bit? in fact be not that progression is The more the better, for ordinary bicycle, the speed of a motor vehicle is not very high, in very little scope, disposes too much number of steps of speeds, differential too small or overlapping phenomenon will occur.Usual many people ride existing three speed, five fast iso-variable velocity bicycles generally all are to hang the 2:1(middling speed) speed ratio ride.Sometimes both made when stepping on the slope, also speed change seldom.Its reason is the speed change trouble, does not have certain skill level, and very difficult extension shelves.And gear shift mode of the present utility model is very simple, and it is not provided with the shift handle, need not use the hand engage a gear during speed change.In the time will riding express, step is along stepping on.And when riding resistances such as upward slope increased, only needing contrary the stepping on of step was slow shelves.Very flexible.
Need during the slow shelves of the utility model that step is contrary steps on, can be uncomfortable when stepping on and cyclist's both feet are contrary? does can influence the cyclist have an effect? not experimental results show that to influence.Because when ordinary bicycle is ridden on general highway, the time of riding fast shelves is many, and the time of riding slow shelves is few.Only when resistance due to climbing increases, just hang slow shelves, just need step against stepping on.Because riding resistance increases, step on that speed (step rotating speed) is low this moment, riding speed is slow, and requires have bigger strength to scrunch pin.And during contrary stepping on, sit limb to increase relatively, under the cooperation of both hands, can very natural weight be pressed in the step whole body, bicycle is made the grade very soon.The but contrary time of stepping on has been grown, and both hands are tired easily, but generally go up a slope the time and not very long, and it is not enough just in time to have remedied this point.
Among the figure (7), (24) and (9) be brake equipment, and the rise wheel hub of stopping of its principle of work and present general-duty is the same, rise when stopping (9) spreading when folding, and be to brake.
Among the figure (7), (23) and (8) are laborsaving ratchet, ratchet, and its function is only to allow wheel clockwise, and can not reverse.
Driving wheel wheel hub principle of work is shown in figure (8):
Accompanying drawing (8) is the buffering of the utility model driving wheel wheel hub, laborsaving principle of work and power scheme drawing.
(46) are frame-front fork (back vents) among the figure, and its skewer connects tightly with two screws (G) in the groove of folding cover (5).(36) be the wheel hub urceolus, top A hole is installed spoke and is used, and wheel hub urceolus (36) relies on end-cover axle shelves (7) to support by steel ball H, and main shaft (42) and axle shelves (6) are screwed connection.Axle shelves (6) are supporting end-cover axle shelves (7) by steel ball (a).Copper sheathing (4) is between axle shelves (6) and folding cover (5).(41) one of recoil spring steel plates are screwed on frame-front fork (back vent) (46), and the other end is pressed on the slip cap (E).Slip cap (E) and fixed gear shaft (40) are bearing fit.Locating dowel pin (F) is fixed on the end-cover axle shelves (7).Ratchet (23) is enclosed within on the fixed gear shaft (40), and ratchet shaft bowl (8) is captiveed joint by screw thread with wheel hub urceolus (36).Ratchet shaft bowl (8) and ratchet (23) are meshing mutually.
Recoil spring steel plate (41) is being oppressed fixed gear shaft (40) towards the direction shown in the arrow C, makes garden heart O
3With garden heart O
2Around garden heart O
1Do the anticlockwise direction swing.As garden heart O
2When putting the position of top dead point (B), because locating dowel pin (F) works old home heart O
2Can not up put again.When the people took bicycle, human weight was pressed to main shaft (42) towards the direction shown in the arrow P, and recoil spring steel plate this moment (41) is compressed garden heart O
2Around garden heart O
1Be flapped toward bottom dead point (B from top dead point (B) with the sun
1).Arrow D represents the direction that wheel advances.The effect of ratchet shaft bowl (8) and ratchet (23) is: only allow wheel clockwise, just only allow wheel hub urceolus (36) to rotate towards the direction shown in the arrow D.
When bicycle is not sat man-hour, because the elastic force of recoil spring steel plate (41) makes garden heart O
2In the position of top dead point (B), when the people took bicycle, recoil spring steel plate (41) was compressed, garden heart O
2From top dead point B along (
) the garden arc shifts to bottom dead point (B
1).Since the human weight difference, garden heart O
2(
) also difference to some extent of position on the arc of garden.When calculating the elastic force size of recoil spring steel plate,, and needn't consider the vehicle size of impulsive force in motion as long as can satisfy human weight.Be transformed into when promoting power that the vehicle level advances and realize cushioning because the utility model is the impulsive force when vehicle fallen.And be not to rely on the elastic force of recoil spring steel plate (41) to realize cushioning merely.So when the gravity P of human body is pressed to main shaft (42), its garden heart O
2Both made and put bottom dead point (B
1) the position, can not influence the buffering effect when riding yet.
When vehicle in motion, just wheel hub urceolus (36) is when the direction shown in the arrow D is rotated, ratchet shaft bowl (8) is gone up at ratchet (23) and is slided.When hollow occurring on the highway, because the inertia when advancing, vehicle does not also fall for the moment, and this moment, vehicle soared, and in this moment, gravity P disappears.At this moment main shaft (42) can be considered fixed in vertical direction, and under the effect of spring plate (41), fixed gear shaft (40) is around one section radian of main shaft (42) anticlockwise direction swing.The essence of This move is exactly wheel center O
1With respect to alignment of shafts O
2Vertically moved down a segment distance.It moves down the size of distance, for tire touch the hole end till, or, garden heart O
2Put till the top dead point (B).After inertia disappeared, under the effect of impulsive force, frame-front fork (back vent) (46) was pressed to main shaft (42) towards the direction shown in the arrow P, at this moment garden heart O
2To be flapped toward bottom dead point (B from top dead point (B)
1), owing to main shaft (42) links to each other with end-cover axle shelves (7), so end-cover axle shelves (7) also will rotate 150 ° towards the direction shown in the arrow D.Because ratchet (23) links to each other with end-cover axle shelves (7), therefore, ratchet (23) has just driven wheel hub urceolus (36) by ratchet shaft bowl (8) and has rotated 150 ° towards the direction shown in the arrow D.This moment the wheel segment distance that just advanced.This shows that the impulsive force when the utility model can fall bicycle is transformed into the power that promotion bicycle level is advanced, and has the labour-saving function.Meanwhile, because of the path of motion of frame-front fork (back vent) (46) vertical drop is transformed into the path of motion of tilt drop, and the resistance when falling increases, so velocity of impact vertically downward slows down greatly, reached the purpose that cushions so again.
When we ride in an automobile, so a kind of sensation is arranged all, after automobile is through sharp pounding of a hollow generation, also have aftershock for several times to occur.Both made bumper has been installed on the automobile, its buffering effect is not very good yet.If by buffering of the present utility model, labour-saving principle of work, the kinetic energy when automobile is fallen is transformed into the power that the propelling vehicle level is advanced, this not only can be fuel-efficient, and can also reach very good buffering effect.Therefore the utility model buffering, labour-saving structural principle not only are adapted to bicycle, but also all vehicles that are adapted to travel on the highway.
Follower wheel hub principle of work is as follows:
Can on end-cover axle shelves (24), rotate freely referring to figure (9) wheel hub urceolus (8), but because the effect of ratchet shaft bowl (25) ratchet (17), wheel hub urceolus (8) can only rotate towards the direction shown in the arrow D, (10) one of recoil spring steel plates are fixed on the macro-axis shelves (11) with screw (12), the other end is pressed on the anchor shaft (5) by the direction shown in the arrow C, under the effect of limiting stopper (G), garden heart O
2Can only
Swing in 150 ° the scope.The buffering of present embodiment, laborsaving principle of work is similar with figure's (8).
Details are as follows for body structure:
In existing bicycle, mostly adopt chain wheel, chain, flywheel to come transferring power.Because the volume of chain wheel, chain is big, this structure can't reduce present existing frame again.Chain wheel in addition, the sealing property of chain is low, and therefore poor lubrication has increased friction drag, has reduced service life.Vehicle body of the present utility model has overcome above-mentioned disadvantage.
With reference to accompanying drawing (10), be double chain-less bicycle body structure scheme drawing
Double chain-less bicycle front and back wheel is drive wheel, and its wheel hub has all used the driving wheel wheel hub shown in the figure (5).Vehicle frame is a trapezoidal shape.The vehicle frame middle part is provided with two trivet muscle.The vehicle frame front end is provided with a standpipe, is settling front fork in the standpipe.The structure of halter and front fork is identical with ordinary bicycle.Front fork end and driving wheel wheel hub link, and its connection mode is in shown in the figure (8).Be provided with the bench of taking for the fore rider pedestrian at the cross member of frame forebody, the bench back is provided with a backrest, the backrest back also be provided with a pair of for after the ride handrail of people's use.Back vent below the bench that the people that rides after the afterbody of cross member of frame is provided with confession takes, back bench is connected with trailing wheel, and trailing wheel has adopted the driving wheel wheel hub shown in the figure (5), and its connection mode is shown in figure (8).Preceding seat limb is 65 °, and the recoil limb is 70 °.
In existing tandem bicycle, owing to adopt chain wheel chain transferring power, and the power of front and back two people output drives a trailing wheel simultaneously, so body structure is bigger, it is longer that centre distance is taken turns in front and back two, and when turn radius was too small, it was very inconvenient to ride.
This vehicle body so bodywork length shortens greatly, only is equivalent to the bodywork length of common single bicycle at present owing to saved Transmissions such as chain wheel, chain, flywheel, and is very flexible when riding.Because front and back wheel all adopted the multi-functional driving wheel wheel hub shown in the figure (5), so have multiple functions such as buffering, laborsaving, speed change, braking, make when riding, more comfortable, brisk.Tandem bicycle scrunches pin simultaneously by two people, and propulsive effort has increased by one times, but riding resistance is not multiplied, so riding speed can improve greatly, also has the characteristics that can ride for a long time simultaneously, and is as the car of riding instead of walk at a distance, rising.Owing to the utlity model has buffering, therefore the labour-saving function is particularly suitable for riding on the relatively poor rural road of road conditions.
The weak point of this vehicle body is: when turn radius was too small, the fore rider pedestrian was inconvenient to scrunch pin, the inertia the when people that rides after main dependence the in propulsive effort source of this moment provides with vehicle '.
The utility model embodiment is as follows:
Embodiment 1:
With reference to accompanying drawing (11), present embodiment is no chain offroad racing structural representation
No chain offroad racing front-wheel is a follower, and its wheel hub has adopted the follower wheel hub shown in the figure (6).Trailing wheel is a drive wheel, has adopted the driving wheel wheel hub shown in the figure (5).The vehicle frame of no chain Mountain bike is trapezoidal.Halter and front fork are being settled in the vehicle frame front portion.Its version is similar with existing bicycle.The front fork end is connected with the follower wheel hub, and its connection mode is in shown in the figure (6), and is identical with existing ordinary bicycle.Bench is being settled at the vehicle frame rear portion, and sitting the pipe lower end is back vent, and back vent is connected with the driving wheel wheel hub of trailing wheel, and its connection mode is shown in figure (8).The seat limb of no chain offroad racing is (78 °-80 °).
Owing to saved chain wheel, chain.Bodywork length greatly reduces, and tare also alleviates greatly.The principal feature of racing car is that riding speed requires height, steps on speed accordingly and also requires height.Present embodiment has adopted bigger seat limb (78 °-80 °).To adapt to per minute is step revolution about 120 times.
From figure (11) as can be seen, bench is beyond the trailing wheel center, move after the center of gravity like this, can front-wheel lift when riding? because racing car is when riding, cyclist's upper body degree that turns forward is big, and the center of gravity of human body certainly will move forward like this, adds the deadweight of parts such as front-wheel, from total load, two-wheeled was middle before and after center of gravity dropped on.So in motion, front-wheel can up not lift.
Owing to be offroad racing, so the road conditions when travelling are bad, when riding on rugged road, vehicle can produce strong vertical tremor, and riding resistance is increased greatly.In existing offroad racing, generally all designed shock absorber, but they do not possess the labour-saving function.The present embodiment front-wheel has been installed the follower wheel hub shown in the figure (6), and trailing wheel has been installed the driving wheel wheel hub shown in the figure (5), makes no chain offroad racing not only have the function of buffering, and can also be laborsaving.We once did such experiment, ride the multi-functional chain-less bicycle of our development, both feet are not pedaled the commentaries on classics step, promptly not to bicycle input propulsive effort, and only by the weight of health, the jump up and down that on bicycle, does not stop, this moment, bicycle just can travel on the highway of level faster, even the little upward slope of some angles is arranged, also can successfully climb up.Kinetic energy when this explanation the utility model can fall vehicle fully is transformed into the power that promotion vehicle level is advanced.Racing car with this function, during contest, its effect is necessarily very good on rugged road.
Racing car needs higher speed ratio and more number of steps of speeds when riding.In order to satisfy this requirement, can change in the driving wheel wheel hub, gear-driven structure design adopts outer mode of drawing the steel wire shift, designs the multi-functional wheel hub of the multiple speed change request that satisfies racing car.
Embodiment 2:
With reference to accompanying drawing (12), present embodiment is that tiltable does not have chain three-wheel vehicle structural representation.
It is drive wheel that tiltable does not have chain three-wheel vehicle front-wheel, and its wheel hub has used the driving wheel wheel hub shown in the figure (5).Two trailing wheels are follower, have adopted the follower wheel hub shown in the figure (6), and its connection mode is directly installed on the long rear axle B.Main shaft (19) shown in promptly long rear axle B and the figure (6) is designed to a bearing.It is acute triangle that tiltable does not have chain tricycle frame, and spider is put the beams in place and is inclined tube, and underbeam is a levelling pipe.The spider front end is connected with front-wheel, and its connection mode is shown in figure (8).Front-wheel is can not turning to of fixing in vertical direction.The spider forebody is provided with standpipe C, is settling halter in the standpipe C, and halter bottom and shift fork A are for being fixedly connected.Latter half of bench, the bench back of having settled of spider is provided with a backrest.The afterbody lower end of spider is provided with a standpipe D.Being provided with a steering shaft in the standpipe D, captives joint with a transverse tube E in the steering shaft bottom.Fork F is captiveed joint with long rear axle B, and fork F is bearing fit in transverse tube E, and under the drive of shift fork A, two trailing wheels is swung, to reach the purpose of turning.
When at present people took existing ordinary bicycle, its riding posture was near erectility, so the fwd area that keeps out the wind is bigger.In order to reduce air resistance, present embodiment just changes cyclist's riding posture into horizontal type by vertical type, reduces the area that keeps out the wind with this.Its concrete grammar is: bench is moved backward, and the height of bench is also to decline.Cyclist's health is just lain backwards like this.Resemble this class and be called the bicycle of horizontal shape, external early having, and have two to take turns horizontal bicycle and the horizontal bicycle of three-wheel.But never put goods on the market in a large number, its major cause has: (1) two stability when taking turns horizontal cycling is poor, and it is bigger than common two wheel bicycle difficulty to get on or off the bus.(2) three wheel relative fixed of the horizontal bicycle of three-wheel, when turning, vehicle frame and three wheels all are subjected to bigger lateral loading, under and the situation that the speed of a motor vehicle is too high too small at turn radius, are easy to cause overturning.(3) two what take turns that horizontal bicycle and the horizontal bicycle of three-wheel all adopt is traditional chain wheel chain transmission mode, especially adopt under the posture of accumbency the cyclist, its vehicle body is longer, and the front and back wheel width between centers is big especially, should not change the too small sharp turn of radius, very inconvenient when riding.
Present embodiment has overcome above-mentioned various disadvantage, and it has saved Transmissions such as chain wheel, chain, and bodywork length is shortened greatly, and riding, it is very convenient to turn.Present embodiment is by the front-wheel direct drive, and because of front-wheel and bench relative fixed, very favourable both feet are stepped on the step in the front-wheel.Present embodiment body forward structure and cyclist can tilt together simultaneously, and the front vehicle wheel part is subjected to lateral loading hardly, and has only mono-load.Control feel is near two wheel bicycles, and the cyclist can go to turn with the wish the same with riding two wheel bicycles.Being about to center of gravity moves to the direction of turning.Like this, though the interval of present embodiment left and right sides trailing wheel much narrow than common three-wheel vehicle, but running at high speed down, also can not overturn during sharply turning.
The handling maneuver of present embodiment is by the driving lever A that links to each other with halter, stirs two trailing wheels and turns to simultaneously and realize turning that when the halter left-handed turning, under the effect of driving lever A, two trailing wheels are put simultaneously, at this moment the bicycle turnon left to the right.On the contrary, if the halter right-hand turning, two trailing wheels are put left, at this moment the bicycle right-hand corner.It is just the same that this and ordinary bicycle are handled custom, do not have unconformable sensation.Because of the present embodiment back is provided with two wheels, thereby improved load-carrying ability.
