Description
Trackless terrestrial vehicle
Current, since energy shock, environmental pollution, and urban traffic congestion and people recognize that more and more motion is for healthy importance.Thereby the effect of bicycle has been subjected to comprising the various countries people's of developed country generally attention again.As for resembling our such developing country, bicycle is just thought highly of by everybody especially, even we can say that it is a kind of popular Personal Transporter that people's daily life be unable to do without.
But, traditional bicycle kind very little, form is too dull, it can not satisfy mankind's's today needs far away, particularly it ride that the not every people of line mode And can both accept, the old,weak,sick and disabled, a lot of people among the women and children especially owing to worry that its stability, safety fear far away it.
In China, we often see that whose family has the sick need of people to send to hospital, and action inconvenient old man will go out, and picks child and goes to school, and buy rice or draw a neither big nor small thing, even peasants catch up with the street to sell dish, do a little transportation, all often by means of bicycle.This effect that it has been described on the one hand is not little.A lot of unsafe factors have also been brought on the other hand.(no data searching)
For the mankind that act as that further bring into play bicycle benefit, current, the trend of reform bicycle is in the ascendant.I am an amateur, and before 4 years, I just consider that rope driving device uses and has a lot of preceences on Manpower propulsion of bicycle.Because I notice that it is a kind of the simplest, the most changeable type of drive.I just take up to carry out research and inquirement from that time.Professional effort through 4 years has obtained some initial achievements.
Principle according to " wheel shaft ", shown in accompanying drawing (1), on the wheel disc of a similar pulley conical disk, fag end is fixed on the bottom portion of groove of wheel disc with a rope, then rope was coiled for two or three week along groove, like this, as long as exert oneself a tow afterbody, wheel disc just can rotate around its center shaft.
If this wheel disc and bicycle quick are connected by a free-wheel clutch, so, when pulling at the running rope rope, the wheel disc rotation just can drive bicycle quick and rotate together.An elastic force just can drive the wheel disc counter-rotation when payout, again rope is wound in the groove of wheel disc and goes.In this process of counter-rotating, because the effect of free-wheel clutch, the wheel disc relative wheel is to skid, and freely dallies.Pull out repeatedly, payout, wheel disc just can constantly back and forth rotate, and constantly rotates and drive wheel.Drive the counter-rotational elastic force of wheel disc, can realize by a volute spiral spring.Perhaps, connecting an extension spring by inverted plate in second groove on wheel disc around another root cord (fag end also is fixed on bottom land) on its tail of rope of drawing realizes.This apparatus features is that mechanical efficiency is than higher.
Shown in accompanying drawing (1), if the tail of rope of drawing in the wheel disc groove is connected on the sleeve pipe, again casing pipe sleeve on a lever that fixed rotating shaft arranged, so, when a masterpiece is used in an end of lever when reciprocating, just can the drive wheels rotation.The benefit of doing like this is, when sleeve pipe when lever slides up and down because the variation of lever resistance arm length, and can reach the purpose of speed change, and be stepless change.The advantage that this driving device is used on the Manpower propulsion of bicycle is:
1. back and forth drive and be more suitable for the human muscle and shrink, the characteristics of diastole are more suitable for the characteristics of human synovial activity.A car is loaded onto two and is overlapped independently rope driving device, two limbs alternately drive, just can accomplish continuous drive, and the circle-shaped of standard bicycle scrunches, even bipod alternately scrunches, also be difficult to accomplish continuous drive, use power-actuated stroke in order to increase, the cyclist has taked pin is tied up to way on the pedal, and this is both dangerous also inconvenient.Some domestic and international reformers think of a plan on big flywheel, connecting lever, set up some mechanisms, make the track of stretcher in the process of scrunching be become the shape of the ellipse that erects one class by circle.Its effect just increases the effective working stroke that scrunches nothing but downwards.But it makes mechanism complicated, has increased weight, and gains and losses balance each other, and ， And is undesirable.
2. the standard bicycle length that flies connecting lever greatly can not be regulated, and the long people of individual high leg, the people of individual short short legs can only scrunch with the same motion amplitude; The cyclist can only scrunch with a fixing motion amplitude in the whole process of riding.Therefore, it is very disadvantageous for giving full play to of human motion function.
And shuttle lever driving device, firmly the stroke length of work done is to change at any time in the driving process, regulate arbitrarily, thereby it can give full play to everyone motor function.And owing to two cover drivings device on the car are independently, therefore, the person's of taking advantage of two limbs are not necessarily leaveed no choice but alternately scrunch, and when being necessary, two limbs can be exerted all one's effort to rush across barrier point simultaneously.
3. simple and compact for structure, light and handy, the rope of rope driving device can change transmission direction arbitrarily by fixed pulley, also can be by movable pulley gain speed or gain power.As the wheel chain driving device, organization distribution is not inflexible for it, and the tight thereby rope driving device of matching requirements can satisfy all kinds, and the requirement of the Manpower propulsion of bicycle of all styles of creates to the needed panoramic bicycle of people.
4. rope driving device can be realized stepless change by short-cut method on a large scale.To be described in the following car example.
5. as accompanying drawing (2), with the rope of drawing in the wheel disc groove guiding by the fixed pulley that is contained in wheel and sticks, from the hollow rotating shaft of wheel fork, upwards draw, outlet is equipped with four bar shaped fixed pulleys, they divide the two-layer groined type of lining up, and each pulley can both independence and freedom rotate, therefore, the relative outlet of the dynamic ropes of drawing not recipient becomes a kind of power wheel that simply can turn to arbitrarily to restriction thereby this is taken turns.This has special meaning for the special Manpower propulsion of bicycle such as wheelchair one class.
6. the cable traction device material requested is complied with the development tendency of new material, thereby seems and have boundless prospects.Such as, parts (waiting compared with the gear sprocket wheel) such as wheel disc pulleys etc. in addition help making with plastics, and ropes etc. help making with nylon, aramid fiber and other lamination coating.Vehicle frames etc. help making with composite materials such as glass-felt plastics.Thereby, simplified process for making greatly, alleviated weight, reduced cost, along with the raising of new material technology level, the reduction of productive costs, the preceence of cord drive Manpower propulsion of bicycle will be more and more outstanding.
7. in 8 or three year fourth phase " external techwatch ", see translate selected passages from the U.S. " MaChine DeSign " nine phases of 8 or two years five or three volumes 44 pages article intermediary introduce: CreatiVe Motion industrial produces the CM-1200 type bicycle that steel cable drives.(above sketch is arranged).Through read over learn it be by a steel cable on the drive bush coiling one or two week after, an end causes on the stretcher by fixed pulley and fixes it, the other end links to each other with an extension spring, its lining is skin-deep by a free-wheel clutch and axletree.Its car profile and standard bicycle are similar.Its driving principle is as follows: the underfooting Pedalling, the pulling steel cable drives lining and rotates, and drives wheel.When not having power to scrunch on the pedal, extension spring shrinks, and oppositely spurs cable wire, makes the lining counter-rotating.(at this moment, the lining relative wheel is that skid) And pulling pedal upwards resets.It is said that its major advantage is laborsaving.Be by frictional transmission between its steel cable and the lining.Therefore, it is inevitable skidding.And for guarantee to restrict and overlap between enough friction force are arranged, cable wire must be in enough strenuouss status at any time.Therefore, the elastic force of that extension spring must be enough big.In addition, again owing to how many strokes of pedal depression, how long spring also must stretch.As seen the requirement of this spring absolute elongation aspect also is very high.In view of this this spring must be not only thick but also grow.The driving device of this car is not considered the speed change problem at all.
The rope driving device of my research, the first, the rope head is the bottom portion of groove that is fixed on wheel disc, has eliminated and has skidded.The second, inverted plate can design smallerly around the groove diameter of cord.Girth is little, and the cord that coils, pulls out is also just short.Therefore, also just low to the requirement of the absolute elongation aspect of the extension spring that links to each other with cord.The 3rd, it is little that the elastic force of coiling dynamic ropes is Yaoed Qiu And, softer because rope is all selected.Moreover, make here and step on sheet reset And and oppositely pull back by dynamic ropes, directly adorn the purpose that a torsion spring reaches answer on the pedal shaft but lean against.Or direct armrest retracts on the hand-driven car.Perhaps, on three-wheel, the stable car of taking of the such energy of four-wheeled, can on stretcher, adorn a belt sleeve, directly take back by pin.It is little that the elastic force of the extension spring that links with cord that therefore, makes wheel disc counter-rotating is Yaoed Qiu And.
Concrete utilization on various Manpower propulsion of bicycle is done some and is exemplified to cable traction device below.
First example, wheel Wheel-chair (1) is shown in accompanying drawing (3)
On the basis of present common wheelchair, each side install a cover rope driving device additional, drive two trailing wheels respectively, with the hands back and forth promote the both sides lever actuated synchronously.The damper brake handle of both sides trailing wheel is housed respectively on two push rods, and like this when wheelchair is wanted turnon left, as long as the right hand pushes hard, left hand touches, and does not push away or even pinches damper brake just.Operation during right-hand corner is then opposite.Brake, then two hands are pinched damper brake simultaneously.Want speed change as long as the sleeve pipe on the push rod is moved up and down just capable.Upwards moving is top gear, is bottom gear to moving down.
If dislike speedup not enough, can on the sleeve pipe on the push rod, adorn a pulley, shown in appropriate section in the accompanying drawing (5), allow the rope that attracts on the sheave dish again tail of rope is fixed on the vehicle body by it.Like this, the speed of a motor vehicle can double on original basis.(this pulley is equivalent to a movable pulley) otherwise, with a little office that movable pulley and rope is simultaneously stuck as long as when push rod is shifted the foremost onto in the time of slowing down significantly, can slow down half, the situation when being equivalent to not adorn movable pulley at this moment.If wish in pull bar, also to go out a masterpiece point merit, as long as between lever and fwd vehicle frame, connect a tension spring.Like this, when you pull back, will overcome the spring tension work done, and when you promoted forward, spring shrank to release energy and helps your a helping hand.Whether the use of this spring can hang up temporarily or throw off.
The comparable wheelchair that has now of wheelchair after improving like this runs a good foot, and the operation of can squaring one's shoulders with sitting straight.Therefore, comfortable nature.If wishing this wheelchair can take action in small range, spin flexibly as original wheelchair.So, you need only second rim brake on the pinching push rod, and then the wheel disc in the rope driving device just can break away from and getting in touch of taking turns, and like this, the function of this wheelchair has just been recovered the function of old wheelchair fully.At this moment, can be with the hands the directly palm annulus action on moving two trailing wheels of plate or spin.
The front both direction of this wheelchair is too little with runner diameter, and rolling efficient is low, and the requirement height of road pavement is unsuitable for the tourism long journey.
The structural principle of getting in touch between wiring wheel disc here and the wheel is shown in accompanying drawing (4), adorning a bicycle quick at the wheel shaft left end that does not rotate by ball bearing of main shaft, on the axle skin on the wheel right side, fixedly adorning a ratchet, on the right axis of wheel, adorning wheel disc by ball bearing of main shaft, the inner ring of the ball bearing of main shaft of this wheel disc can endwisely slip in the axle upper edge, but can not rotate.On wheel disc, several ratchets are housed by wheel one side (left side), compression spring of suit on the right axis of wheel disc, it presses wheel disc to such an extent that rely on wheel, becomes one so the ratchet on the wheel disc just cooperates with ratchet on the axletree skin and overlaps free-wheel clutch.Like this, wheel disc and wheel have just connected by this free-wheel clutch.(at the beginning of cooperating, between the two as long as one rotate slightly to the skid direction, just can interlock on), when breaking away from, as long as the inner ring by a thin steel rope and wheel disc ball bearing of main shaft couples together a pulling to the right, just can break away from, the distance of this left and right sides slippage need only several millimeters to 1 centimetre just capable.Therefore, thin steel rope can be directed on the rim brake with plastic casing and just can control.Certainly, get in touch also with the free-wheel clutch of other form and be fine.
Such as, adorn a planar sawtooth ratchet sheet on the above-mentioned wheel right side, like this, when wheel and dish when being close to, two ratchet sheets are interlock and having an effect mutually just.When wheel and disk detachment, wheel just can free positive and negative rotation.Perhaps on the axle skin of the above-mentioned wheel right side, adorn a finished product free-wheel clutch, when wheel disc and it near the time, just connect and have an effect, otherwise then break away from its interlock.
Second example, wheel Wheel-chair (2) is shown in accompanying drawing (5)
Universally remove two of top a kind of fronts of taking turns Wheel-chair are little, place the center, front with runner and change diameter bigger universal with runner.Install a directional control bar on this car of taking turns fork rotating shaft top by one " power-transfer clutch ".Still add partly that as for other example is described.The advantage of this kind wheelchair is: the front-wheel diameter increases, and rolling resistance is little, and current performance is good, can travel on highway, street, does not lose more expert moving the alerting ability that spins simultaneously again.As long as hold directional control bar (left hand and right hand is all right, because joystick is in the dead ahead, seat) slightly to pressing down (gravity of armrest itself just) with one, power-transfer clutch is interlock just, and the sway joystick just can be controlled travel direction.Like this, can accomplish just that on the other hand controlling party is to, a hand propelled lever actuated.And two hands can swap operation.When particularly running into the downhill path, by the joystick controlling party to the reliability that could guarantee travel direction.One decontrols hand when without joystick, and joystick just can make progress under the effect of an elastic force and lift slightly, and at this moment, throw-out-of clutch, front-wheel can be used as one again and universally freely rotate with runner.At this moment, but both hands push away the both sides lever actuated synchronously, also can allow the with the hands direct annulus on moving two trailing wheels of plate of wheel disc separating wheel, take action among a small circle in, spin.The directional control bar is the time spent not, can with its from the middle part by a hinge forward to folding weak point, it is short also can to do two intercepts as wireless telescopic antenna.Like this, it is open salubrious that this wheelchair front can keep, and allows the person of taking advantage of feel comfortable nature.
This wheelchair is can a car dual-purpose, has both played common wheelchair effect, play hand seat coach again, thereby it can satisfy invalid's action requirement all sidedly.
These wheelchair energy two hands are independent drive respectively, also can drive by both hands, direct palm wheel drive again, thereby, the person of taking advantage of is conversion campaign posture selectively, thereby can allow each part muscle of human body alternately obtain work and rest, alleviate sense of fatigue and uninteresting sense, thereby made the person's of taking advantage of motor function can fully obtain performance.
Pushrod movement need be squared one's shoulders and be raised one's arm, and it, has special exercise and use concerning the people who bends over one's desk working for a long time and learn for the people who lacks motion exercise.Therefore, this car also can be as a kind of functional training car, and the sports car uses.
Above-mentioned " power-transfer clutch " is shown in the partial enlarged drawing in the accompanying drawing (5), the rotating shaft of front-wheel (universal with runner) car fork is passed and is maintained static after the moving bearing sleeve, close fit ground installation in the top one has an end of the denture clutch of trapezoidal tooth, and its flank of tooth up.Outside the bearing sleeve, one of the suit outer tube that can freely rotate around bearing sleeve again, be respectively with the turning cylinder bearing and the guide groove of directional control bar in these outer tube two outsides, they can rotate joystick at one among a small circle up and down, can make joystick do as a wholely to rotate on horizontal surface around above-mentioned bearing sleeve with outer tube simultaneously again.The other end of denture clutch also is housed below joystick, and its flank of tooth down, and is corresponding with an end at above-mentioned wheel fork top.When joystick was depressed downwards, the tooth on two increment faces is tabling just, and like this, the wheel fork rotating shaft that is in the center just is coupled to a concentric rotor and is controlled by joystick with outer field rotating jacket pipe.When joystick popped up, two had the increment face just to separate, and at this moment, the rotating shaft of front-fork again can be freely with commentaries on classics.
Here, if after removing front-fork, handle, front-wheel with an ordinary bicycle, with an axle bearing seat behind it and the epicycle chair back is connected, just can be unified into the touristy coach of the double driving of a cover.Certainly, also available it come passenger traffic the old,weak,sick and disabled, women and children.
The 3rd example wheel Wheel-chair (3) is shown in accompanying drawing (6)
This takes turns Wheel-chair and last one example is different is: on the inner shafts skin of two rear power wheels, adorn a gear Z each close fit
3, shown in figure (6), the leg-of-mutton adapter plate (the O axle is fixed on the vehicle frame) that above this gear, has an energy to rotate around the O axle, two gear Z are installed on engagement ground on adapter plate
1, Z
2When adapter plate when O axle clockwise direction rotates an angle, Z
1Just with Z
3Engagement.When adapter plate during around angle of O axle anticlockwise motion, Z
2Just with Z
3Engagement.
Gear Z
1Interrelate by a free-wheel clutch and self rotating shaft, the wiring wheel disc is housed in this rotating shaft close fit.When hand pushed lever, rope just drives wheel disc and rotates, wheel disc driven gear Z
1Rotate.At this moment, if Z
1Directly and Z
3Engagement then will drive Z
3Rotate, wheel just rotates forward.And if Z
1Pass through Z
2Ability and Z
3Engagement, wheel just reverses so.Therefore, by the turned position of control adapter plate, just can control power operated wheel and be just changes or reverses.Can adorn a spring, draw adapter plate to such an extent that turn to Z in the direction of the clock
1, Z
3Position engaged, (promptly figure goes up drawn position) drive wheels this moment is just changeed.If draw by angle of anticlockwise motion, make Z to adapter plate with a thin steel rope
2With Z
3Engagement, then power driven wheel reversing.If steel cable only spurs the half that adapter plate turns over above-mentioned angle, during the midway location of promptly above-mentioned two extreme positions, gear Z then
3Neither with Z
1The engagement also not with Z
2Engagement and be in the neutral state.At this moment, wheel can free positive and negative rotation.Thin steel rope can be controlled by " three block locks " on the hand pushed lever.
This car can the both hands radius-rod drive advances, falls back, turning, original place are spinned.Certainly also steering on the other hand, radius-rod drive on the other hand, its purposes and last example are similar to.
The 4th routine wheelchair (4) is shown in accompanying drawing (7)
The front-wheel of this kind wheelchair be two little universal with runner, trailing wheel is to mention " universal dynamical wheel " in the 5th of two front advantage (accompanying drawing (2)).
The advantage of this wheelchair is that when two power wheels turned to the place ahead, it can be operated push rod as the wheel Wheel-chair in first example and travel.When two power wheels turned to oblique the place ahead, wheelchair can be towards tiltedly sailing unchangeably, and when the same horizontal side of two rear-axle steerings, wheelchair is skidding (towards constant, still forward) laterally.Two trailing wheels are rearwards the time, and wheelchair just falls back, if lastly just can spin on the spot backwards one day.All these action, all by radius-rod drive, turning to of two-wheeled wheels is to realize by rotating the rotating disk that two-wheeled sticks.
The diameter of power wheel unsuitable big (big the side of occupationing of land), general 30 centimetres to 40 centimetres more suitable, like this, this wheelchair can be made small and exquisite flexibly, and is convenient especially in indoor use.
The 5th motor-driven auxiliary sedan-type cycle of example such as accompanying drawing (8)
This car has four wheels, and seat is in the middle of four-wheel.Seat is low, and the person of taking advantage of sits the shape that crouches, and scrunches forward.Therefore, good stability, safe, air resistance is little, and ride comfort, type of drive meet human engineering mechanics's requirement.
Its dynamical axis (hind axle) is contained in two longeron ends by two ball bearing of main shafts.Two trailing wheels, the large fluted disc of two wiring wheel discs and motor-driven transmission (or friction wheel) all is to be installed on this dynamical axis by ball bearing of main shaft and free-wheel clutch.Changes forward when two wiring wheel discs and motor-driven transmission large fluted disc (friction wheel) like this, can both drive hind axle changes (single driving is changeed, and it is all right that still combination drives commentaries on classics) forward, and hind axle changes forward and just can drive two trailing wheels and change forward.Turn left when curved when car, the trailing wheel on the right just rotates in advance, turns right when curved, and the trailing wheel on the left side just rotates in advance.Because wheel and axle all are equipped with ball bearing of main shaft between axle and the vehicle body (longeron), therefore, have improved the sliding performance of this car.After turning round, or after unpowered the sliding, the both sides trailing wheel may produce a bit " differing ".Promptly rear flank wheel becomes power wheel with the axle interlock, and opposite side in the interlock, does not temporarily become flower wheel.But owing to flower wheel always will skid in the generation hysteresis of relative ground, and driving wheel (coaxial one) relative always ground generation is skidded in advance, thereby needs only after a period of time, and temporary transient flower wheel can be caught up with and interlock by dynamical axis again, also becomes driving wheel.Certainly, the overriding clutch on these two trailing wheels will be selected short more good more of idle running.
First kind of speed change: can on the sleeve pipe on the pedal lever, adorn a miniature cocurrent electromotor, load onto rubber friction wheel on the motor reel, make it to roll along lever, thereby driving sleeve pipe moves, in addition, also on sleeve pipe, add the drg of a midget relay control, when energising, brake action does not take place in the actuating of relay, and electrical motor rotation simultaneously drives sleeve pipe and moves.When outage, the electrical motor stall, relay is not had an effect, and drg produces braking under the elastic force effect, sleeve pipe can not at will be moved.Change direction of current and just can change the electrical motor rotation direction, thereby change the moving direction of sleeve pipe.Telegraph key can be contained on the handlebar of seat both sides, and operation easily.Make and move speedup on the sleeve pipe, be chosen in lever and return back to the position later backward and carry out, make sleeve pipe move down deceleration, be chosen in the position that lever steps on forward after surpassing vertical position and carry out (can both carry out when still being static during motion) above vertical position.
Second kind of speed change: respectively adorn a fixed pulley as accompanying drawing (9) pedal lever top that is shown in and lower end, the ratchet of the pulley of lower end and a rectangular teeth is combined, sleeve pipe on the thin chape (the same with regard to the transmission of elephant hide belt wheel) that overlaps a closure on two pulleys allows lever and chape link and are fixed in a bit, like this, when on the pulley of the lower end axle at it during positive and negative rotations, belt just drives sleeve pipe and moves up and down (will allow belt and following head sheave not skid) along lever.The fabricate block of lower end " pulley ratchet " is to be sleeved on the rolling bearing skin of lever, makes their cooperation tight, and they can not at will be relatively rotated.Like this, when lever back and forth rotated, " pulley ratchet " also and then rotated together synchronously, and they keep static relatively.If have a ratchet and this ratchet meshing, skid at lever relative ratchet of ratchet when direction is rotated so, still keep static relatively between them, and when lever rotates to another way, ratchet and ratchet are killed, stop ratchet to rotate, at this moment " ratchet pulley " rotates relative to the bearing skin of lever, so the belt drive sleeve pipe on pulley moves.Lever is crank motion constantly, and sleeve pipe is just moved a certain distance again and again.
If the direction of ratchet conversely, so when the lever crank motion, just sleeve pipe can move round about.Add shown in the accompanying drawing (9).In the side of ratchet Z, adorn an O on the longeron of car and a two-way ratchet means is installed by rotating shaft O.A, B are respectively two reverse ratchets, and this device can rotate around the O axle.A ratchet and ratchet engaged under the tension of extension spring D.When control wire C overcame spring force and draws this device to such an extent that turn to as shown in the figure the position, A, B two ratchets all broke away from ratchet, and be neutral this moment.Lever crank motion, sleeve pipe do not move, not speed change.Just can draw to such an extent that forward the position of ratchet B and ratchet engaged to when C continues this device of pulling.Like this, make two-way ratchet means place one of three retainings, treadle, just can accomplish to make on the sleeve pipe and move (speedup), move down (deceleration) or hang neutral, not speed change as long as handle cord C.Handling cord can be with the steel cable of present bicycle " three fly " change-speed box, and plastic casing and three block locks are just capable.
The third speed change.Shown in figure (10), can realize by the sleeve pipe lifting on the thin steel rope pulling pedal lever.The then speedup that makes it to rise of drawing, pine make it lever pedaled surpass the upright position after, under the effect of dynamic ropes, glide and realize slowing down.What glide, by how much deciding of the cord that loosens.The pulling cord can be realized coiling by horizontal rotating shaft under seat of hand positive and negative rotation, still discharges cord and controls.The pulling cord will or be regained in the process that pedal is regained and carry out in motionless.As for loosen steel cable then be when carry out all right.As for sleeve pipe on the rise and possible problem of sliding in the process that lever is regained, can solve by multiple way.Such as applying an elastic force downwards, or allow rope (or pulley) be positioned on a galianconism top of stretching out to oblique below on the sleeve pipe.Like this, when dynamic ropes spurs obliquely upward, just can produce big moment, the cover tubotorsion is held on the lever, increase friction force and sliding motionless.The 3rd way is: adorn a little cam on sleeve pipe, the little mechanism of eccentric shaft and so on just locks when allowing dynamic ropes upwards spur.
Turning to of this car is the two one control levers manipulation of drawing by two fronts wheel spindle, connects a transverse brace (it passes) through hinge under seat between the two bar ends, so that turning to of left and right wheels reaches needed synchronous rotation.Handlebar is in seat two downsides.Under this car seat, all very open behind the backrest, this is to packed battery, and motor or spark ignition engine etc. is all easily had a surplus.The not motility reversing of this car, people's push-and-pull reversing of getting off also will be thrown off the free-wheel clutch of two trailing wheels in advance.The stretcher of this car be stepped on it to the seat below stuck when getting off so long.The seat front is open like this, just gets on or off the bus easily.If want the extra bus cover, can be contained in its hinge after car sits, allow the car cover start backward, like this, it is easily same to get on or off the bus, and also can add a flat-top retaining day rain simply.Ben Cheruo wants power reversing, can make following change: two trailing wheels, and one is fixing extremely on dynamical axis, and one its can freely be dallied.The wheel disc of two rope driving devices is installed by the gear rotation direction reverser as in the 3rd example of front, and motor-driven transmission can be adopted the friction wheel transmission, and active friction wheel is not in that the time spent can throw off.Ben Cheruo will carry small children and can mount a single wheel (universal with runner) trailer thereafter, and this car will be a popular walking-replacing tool sutable for men, women, and children more likely in coming few decades.Along with the appearance of novel battery and electrical motor, it will have survivability more.
The 6th routine three-wheel sedan-type cycle such as accompanying drawing (11)
Two rear power wheels are contained in the two ends of a fixing axle that does not change by ball bearing of main shaft, and are the same with the dress method of power wheel in first example, second example.It also is for convenient when pushing away, forgetting about it car that the trailing wheel free-wheel clutch can be thrown off.Fixedly adorn two longerons on hind axle, the longeron front end is adorned a crossbeam, and a wheel flutter is adorned in the center before crossbeam.
Manipulation turns to by cord drive, and shown in figure (11) bottom, the steerage gear rope is formed a C/LOOP.On the crossbeam of both sides, adorn two actuating linkagies, its rotating shaft is in the middle of lever, its lower end and rope fixed connection, the upper end is a control handle, moves forward and backward as long as hold it, just can control and turn to, a hand also can be handled, and about 20 centimetres apart from ground of front-axle beams surround the empty frame of one 40 centimeter square before the seat, between two longerons, after the front cross rail, the person of taking advantage of can stride into then earlier and take a seat, and is easily generous.The seat of chaise longue formula is very comfortable, and it is reasonable to scrunch force method, and air resistance is little, is a kind of high-speed bicycle, and speed change is with reference to the 5th example.
Horizontal sporting car of the 7th routine three-wheel such as accompanying drawing (12)
Two power wheels are preposition, are contained in the two ends of V-type crossbeam respectively, adorn two longerons in V-type crossbeam bottom, and longeron is high more than 10 centimetres apart from ground, and at two longeron front ends dress pedal lever, a crossbeam and a wheel flutter are adorned in the longeron rear end.Plane among two longerons is the person's of taking advantage of part of lying on the back, and the head pillow is high, and both sides suitably are the handlebar position of control to usefulness at a distance on the shoulders.
This car structure is very simple, and the front is open, and visual field is fabulous, and it is also very convenient to get on or off the bus, and this is that general horizontal bicycle is difficult to accomplish, speed change is as the 5th example.As add a car cover and then can become a kind of sporting car of competing for speed, weak point is that control is to stable inadequately.
The 8th example is sat horizontal two-wheeled cycle such as accompanying drawing (13)
As adorning the common gear that flies for a short time, each adorns wiring wheel disc respectively by free-wheel clutch on the rear power wheel two side shaft skins.Steering front wheel is contained in the seat front lower place, handlebar directly is fixed on the front fork, handle is in the seat down either side, pedal lever is loaded on the preceding lower end of vehicle frame, its transmission system is very simple also very ingenious, two ropes of being drawn by two wheel discs cause movable pulley on the pedal lever by fixed pulley respectively, by passing again behind the movable pulley after the slip ring on the very loosening inclined tube that is enclosed within the vehicle frame front end, tail of rope is fixed near the bearing of stretcher rotating shaft the inclined tube at last, like this, when step tread forward the time, the very loosening slip ring that is enclosed within on the inclined tube just can (this slip ring be had a mind to do heavyly to lower slider under the effect of power, slick and sly) at this moment, just can reach the purpose of deceleration.This sleeve pipe slides into when the most beneath, half when actuating speed has only topmost.Otherwise, speedup, then tie down this slip ring and upwards carry with a cord, allowing this slip ring stop going up at various height then has different speed class.The thin steel rope of control slip ring lifting is the third way in the 5th example also, is discharged by the coiling of a horizontal rotating shaft under seat and controls, and the crank of hand seat downside makes the rotating shaft coiling cord sleeve pipe then speedup that rises, otherwise sleeve pipe glides and then slows down.This root rotating shaft is to limit it by a friction force, does not allow its careless rotation.Well imagine that when slip ring was subjected to the application force " excessive " of dynamic ropes, it can draw cord and earn downwards, thus overcome friction, and force the rotating shaft revolution to discharge cord.Its as a result slip ring move down and play deceleration effort, visible as long as adjust the size of friction force as required, as long as the power overrate on the stretcher, it just can automatic deceleration.
The characteristics of this car are simple and reasonable for structure, compact, ride comfort.Shortcoming is car starting inconvenience, go-cart difficulty on foot, if install additional in both sides two can folding and unfolding little auxiliary wheel, this to starting, stop, may be very helpful.
The 9th routine toy tricycle such as accompanying drawing (14)
The power wheel of more than 30 40 centimetres of two diameters is contained in rear axle two ends of not rotating as in the 6th example, wheel disc can be thrown off with wheel.Fixedly adorn a longeron at the trailing wheel middle part, its length is preferably wanted suitably to extend shortening, to adapt to the long children of different legs.Adorn the about 20 centimetres steering front wheel of a diameter at the longeron front end by wheel fork, make its wheel shaft longer, both sides are respectively stretched out more than ten centimetre, and allowing by bus, children's two sufficient stepping on control turn to.
On the tee T vehicle frame of rear axle and longeron composition, adorn an arm-chair.Adorn the bearing support of a hand pushed lever under the vehicle frame, the both sides push rod is installed.
This car can come speed change by the sleeve pipe on the hand mobile putter equally.This car car body is little, and is simple in structure, in light weight, run a good foot, and spins flexibly safety and stability.Thereby both can allow children do the usefulness of travelling, moving, also can do children's short distance walking-replacing tool.
The tenth example motor-driven auxiliary sedan-type cycle (2) accompanying drawing (15)
On the basis of the 5th routine sedan-type cycle, change body structure once get off as figure, the speed-changing mechanism of the 8th example is used up, just form another kind of motor-driven auxiliary sedan-type cycle again.
