Put down in writing in history 110 years Chinese
Zhang Heng, 233 years three states
Ma JunAll made vehicle pointing to the south; 477 years Liu Song's Zu Chongzhis have clever thought, and Chang Weiyi more constructs.Swallow is respectful after being separated by 550 years has done nine wheel southward pointing carts that five gears that tooth arranged consist of in 1027; Wu Deren had been retrofit into accurately luxury vehicle pointing to the south of guide in 1107.
In Chinese patent 200810181168.1 summaries: recording and narrating the people who copies vehicle pointing to the south at first literal according to " Song Shi With takes will " of China is the historian king canopy of the heavens, nineteen fifty-nine is collected in The National Museum of Chinese History by his the respectful vehicle pointing to the south of swallow of design, but, do not possess the function of locating guide.And think that always the respectful vehicle pointing to the south of swallow is identical with the Wu Deren vehicle pointing to the south, the Wu Deren vehicle pointing to the south of document record do not occur meeting.
Summary of the invention
Wu Deren waits nine puppets to cater to holy meaning with celestial being, and vehicle body " five cun of wealthy nine chis " is the meaning of " 95 most distinguished ", get " seven cun of wheel diameter five chis " four cun of one zhang one chis of wheelspan, the railway carriage both sides each remaining nine cun five minutes; The upper strata is sun, puts nine honor idols, and lower floor is cloudy, establishes nine gears.Do not manifest nowhere the speciality that this vehicle pointing to the south is the special use of emperor's flags, weapons, etc. carried by a guard of honor.Its learning value is not higher than the respectful vehicle pointing to the south of swallow, though still have the value of restoring its original appearance as a historical invention now, necessity of analyzing its research process is arranged also.Valuable point is the increasing of large flat tooth number, has improved pointing accuracy, and the clutch coupling of folded wheel etc. is the innovation that is different from the respectful clutch coupling of swallow up and down.The respectful clutch coupling of swallow is the clutch coupling of horizontal direction activity, and the Wu Deren clutch coupling is the clutch coupling of vertical direction activity, and both are veriform clutch couplinges.
The train meshing relation is analyzed: from the modulus minimum, upper folded wheel mountain type tooth, between cog removed one-inch one minute mutually, large flat wheel is star-like, between cog removes five lis of one-inch two minutes mutually, upper folded wheel moves up and down and the clutch of large flat wheel, between cog go mutually to differ from one minute five lis be that ancients' measuring method does not only have to cause thing to be as the criterion due to the concept of pitch circle; Upper folded wheel plugs together with lower folded wheel; Little flat wheel mountain type tooth, between cog go one-inch nine minutes and lower folded wheel star-like mutually, between cog go mutually two cun one minute, the engagement of two gears also is due to the non-pitch circle concept; Little flat wheel mountain type, between cog remove one-inch nine minutes and attached foot wheel mountain type mutually, between cog go mutually two cun one minute, the vertical break-in of two gears should be all mountain type tooth engagement, control breaks away from when not carrying out guide work.Suspect has the error of measurement or record error herein, should be four lis of one-inch nine minutes according to the space width of girth and the attached sufficient gear of Tooth Number Calculation, and little flat wheel space width also is four lis of one-inch nine minutes; Document record " attached foot wheel between cog go mutually two cun one minute " is wrong.Folded wheel is as the criterion more than the clutch of upper folded wheel and car pin vertical wheel, and car pin vertical wheel between cog goes brick closer to divide five lis to be because it will be fixed on the car body mutually, and what work is the inner round portion that meshes with upper folded wheel.Upper folded wheel is that an existing rotation has again the movement parts that axially moves up and down, and this is the feature of Wu Deren clutch coupling.
The vehicle pointing to the south pointing accuracy of the clutch type of Wu Deren increases, and key is that the opposite side wheel is locked when can accomplish the flat greatly wheel of a side drive.The number of teeth of each gear can be according to the document record data, and the increase of the number of teeth is conducive to the raising of precision.The number of teeth also can be changed slightly, but the reason of change must be arranged.Examination is changed as follows: attached sufficient gear 24 teeth are feasible; It is 1 to 2.0833 that the ratio of large flat wheel 100 teeth and 24 teeth causes wheel diameter and the ratio of wheelspan, and the calibration of 100 teeth difficulty is not as changing large flat the wheel into 96 teeth, and making wheel diameter and the ratio of wheelspan is 1 to 2 or 2 to 3; Little flat wheel 17 teeth deduct a tooth and can make things convenient for calibration, do not affect precision.The up and down folded wheel of 32 teeth and car pin vertical wheel are two cover clutch couplinges.The vertical gear of car pin is in fact the locking jack, and it is fixed on the car body, and it has tooth and does not rotate and do not include gear; Lower wheel 32 teeth of folding are double acting gears, the star-like tooth in outer ring and little flat wheel engagement, and inner ring and upper folded wheel slide and mesh; Upper folded gear is special " mountain " type gear 32 teeth.The end face tooth is long general, and bottom surface tooth length has three gear thickness, and the major axis that has at center can move up and down, and has three to stop height, gear end face tooth and large flat wheel engagement when the highest; Reduce by one and half gear thickness for breaking away from large flat wheel location; When minimum and the vertical gear of car pin plug together and stop vehicle wheel rotation.Little flat wheel is mountain type gear, 16 teeth, double cog, the center is fixed on the major axis that can slide up and down, above the long twice of tooth,, below flute profile normal, have two to stop height, during work little flat wheel low level respectively with attached sufficient gear, lower folded wheel engagement.Break away from attached sufficient gear when high-order, be used in not do when pointing to and use, to reduce wear.
Restore the Wu Deren vehicle pointing to the south be correctly to understand the fuzzy document of that section " in to large flat wheel.It takes turns eight cun of three chis in footpath, encloses four cun of one zhang one chis, goes out tooth 100, and between cog removes five lis of one-inch two minutes mutually, logical upper leftly falls from right to left." and " about after each steamboat one of shafts, anodontia, be bamboo { Tan } and rope on Y-axis, meet turning right makes right shafts steamboat touch right the wheel, if turn left to make left shafts steamboat touch revolver.Capable then fairchild hands over and guide." first leading portion legibility, " logical upper left fall from right to left " doubted and is " rising and falling about logical folded wheel ", be large flat wheel by about the different sense of rotation of rising and falling respectively of upper folded wheel.Second is position and the effect of saying steamboat, what thing is steamboat that " { Tan } " of bamboo { Tan } refers to actually? " meeting turns right makes right shafts steamboat touch right the wheel, if turn left to make left shafts steamboat touch revolver if with the back." inverting, this thing is bordering on seesaw.But three steady state (SS)s are arranged: left height, equal, right height.Target is that right-hand folded wheel falls during right-hand rotation, " makes right shafts (seesaw right-hand member) steamboat touch (putting) right side (the upper folded wheel) wheel that falls " exactly; The invention that mobile steamboat cooperates rope (bamboo { Tan }) can amplify corner displacement amount twice is that the respectful vehicle pointing to the south of swallow begins, and the Wu Deren vehicle pointing to the south continues to be generalized to the amplification distance of positions in the application of the amount of moving twice.Amount of movement when the design of seesaw jaw touches shaft has amplified, the steamboat at seesaw two ends further amplifies again distance twice, makes shaft touch the seesaw jaw and only needs about 2 degree corners, and seesaw just rotates about 5 degree, two ends are moved about three cun, the about six cun distances of upper folded wheel lifting.
Wu Deren vehicle pointing to the south: stir the seesaw of upwards establishing at seesaw 10 middle parts when shaft 13 turns to pincerlike mouthful 11, seesaw tilts, steamboat 14 is established at the seesaw two ends, rope 9 is fastened on the car body below the steamboat, upwards oppositely be fixed on lifting column 8 bottoms of clutch coupling through steamboat, about hold up upper folded wheel 3 liftings that slide plate is controlled respectively two vertical axial clutches; Liter person and large flat wheel 4 engagements, the person of falling engages with car pin vertical wheel 7, and wheel is locked; The equal space-time in the left and right sides revolves.
The seesaw rear view is seen slightly and is " people " font, is divided in two parts, and the rear portion is that operating part is equal with the clutch tooth wheels neat, and there is steamboat at its two ends, and the seesaw anteriomedial is upwards established the seesaw jaw, accepts the anterior control of single shafts.Therefore seesaw is overlooked and is " worker " font.
Course of work summary: shaft was turned right at car body when car was turned right, and touched seesaw when reaching certain angle pincerlike mouthful 11, and seesaw begins action, seesaw right low left high, about 5 degree of corner, folded wheel and large flat wheel engagement on the left side; Folded wheel engages with car pin vertical wheel downwards on the right side, and right side wheels locking stall namely " touches right the wheel "; Driving is turned right before the left wheel, and large flat wheel turns left, and the celestial being is guide still.In the said process, upper folded wheel meshes as long as profile of tooth is reasonable with large flat wheel, and engagement can be carried out smoothly; Folded wheel lower tooth and car pin found the probability that gear plugs together wait on the side in addition, and this moment, rope loosened, naturally action when condition to be plugged together reaches.
Performance analysis: the road surface has little rugged, and a side is jolted, and shaft does not rotate to trigger angle, so on pointing to without impact; Sensitivity can reach appropriate degree with the gap of stirring of adjusting shaft front end and seesaw jaw; A waiting status appears in clutch when operation, and the error in pointing of 360/24/4=3.75 degree appears in maximum, but about two sides can offset.In actual use, Chang Yiwu vehicle pointing to the south colleague just can guarantee the reliable of net result.
The wheelspan of Wu Deren vehicle pointing to the south is two-to-one with the ratio in wheel footpath, and above-mentioned parts seem on the low side.Therefore, designed two-layer gear, 13 gears on upper strata are: and the coaxial centre wheel of the flat greatly wheel of lower floor, mountain type 32 teeth, it respectively mesh star gear train 32 teeth (number of teeth can change) all around, each star gear train outwards meshes two mountain types again and takes turns 32 teeth, the centre wheel vertical pivot top celestial being that shows the way that stands, peripheral eight upper discrete four boys of mountain types wheel and tortoise, crane each two.
The wheel of Wu Deren vehicle pointing to the south design is positive isosceles triangle with single shafts axle and distributes, and the mode that this single shafts movable axis draws is conducive to wheel and follows and turn to.The locking of wheel make this follow more reliable, the impulsive force when also having alleviated simultaneously the locking wheel between gear.
Have query in the Wu Deren vehicle pointing to the south document: 1. add the number of teeth of greatly flat wheel gear for the pointing accuracy that improves vehicle pointing to the south and the number of teeth of attached sufficient gear is crucial, the number of teeth of clutch gear there is no need to be increased to 32 teeth.The wheel diameter of vehicle pointing to the south is relevant with the gear ratio of large flat wheel and attached sufficient gear with the ratio of wheelspan, large flat tooth number/(the attached sufficient gear number of teeth of 2*)=wheelspan/wheel footpath.Be 96/ (24*2)=2, wheelspan 11.4 chis, wheel footpath 5.7 chis, seem wide, real for Wu Deren is 95 most distinguisheds that illustrious imperial power is pursued, in order to obtain five cun of compartment nine chis, each works of revising at a distance of nine cun numbers of 95 of five minutes of wheel and both sides, compartment there is no practical value.Actual useful vehicle pointing to the south should be, attached sufficient gear is made into 32 teeth, 96/ (32*2)=1.5 then, wheelspan eight chis, wheel footpath, three cun three of 5 chi, overall ratio coordination.Need not upper strata tortoise, crane, boy and gather together enough nine numbers.On the contrary should design " eight lamps, four dividing plates " localizer of greasy weather lamplight direction, use during for greasy weather and dusk, night flight or navigation.
2. " two little flat wheels respectively have iron weight one " is interpreted as little flat wheel lifting clutch by the descendant, and the iron weight is the counterweight of being afraid of that little flat wheel deadweight adds not.Little flat take turns the below be difficult to lay the iron weight over against wheel shaft, so draw 1, Fig. 2 does not have the iron weight.The horizontal trend of the automatic recovery of seesaw is only the place that needs iron weight counterweight.At Fig. 3 of improved elevating disengaging type vehicle pointing to the south, be appreciated that the effect of iron weight among Fig. 4.The iron weight only needs one, need not being called two.
In order to restore the Wu Deren vehicle pointing to the south and to make it have guide function, even if it is perfect to increase individual iron weight such as Fig. 5 in structure shown in Figure 1.The feature of practical Wu Naruhito disengaging type vehicle pointing to the south is: attached foot wheel changes 32 teeth into, and folded wheel is integrated and changes 24 teeth into and rename as lifting wheel up and down, and this takes turns top and bottom chevron tooth, outer rim is the star tooth; Below little flat wheel changes into for chevron, above chevron add in addition a wheel face and consist of " mouse cage " type structure and the engagement of upper lower whorl, " mouse cage " highly cooperates with upper lower whorl lifting; Steamboat is taken turns erect-position with being connected of lifting column 8 because of attached foot and is changed into the leading flank that falls column 8; Attached foot wheel 1 drives little flat wheel 2, little flat wheel and lifting wheel 3-2 engagement, and lifting wheel can endwisely slip; Shaft 13 did not touch seesaw pincerlike mouthful 11 when car was kept straight on, seesaw 10 left and right sides balances, two steamboats 14 are contour, rope 9 affects left and right sides lifting column 8 contour, about upper folded wheel 15 contour, about each gear idle running, large flat wheel 4 is static; When shaft promoted the pincerlike mouth of seesaw, seesaw tilted, the side's of rising lifting wheel and large flat 4 engagements of taking turns, and center pillar 5 is followed rotation; The side's of decline lifting wheel and car pin vertical wheel 7 plug together, and the party's wheel stops; When breaking away from the pincerlike mouth of seesaw in the middle of shaft returns, seesaw left and right sides under the effect of iron weight 16 is equal.
Do not do guide when work, the support 17 of little flat wheel outwards rotates about 8 degree take the axle of lifting wheel 18 and breaks away from attached foot wheel 1 as the center of circle, simultaneously wedge shape wood 22 is inserted in the bridges and culverts of stop bridges 21 (seeing Fig. 2).
Two parts before and after seesaw 10 has are overlooked the font such as " worker ", and anterior shaft 13 is at the pincerlike mouthful 11 interior shake-up seesaws of seesaw, and seesaw two ends, rear portion respectively have steamboat 15 liftings to drive lifting column 8.
The structure of " eight lamps, four dividing plates " localizer is: under center pillar shows the way the celestial being, equidistantly establish eight lamps by the orientation, the low inclination of taking advantage of a situation in high south, north; Four dividing plates are established in the four corners of the world under the lamp, and the dividing plate top to center pillar, is crossed behind the center pillar tiltedly lower to thing south three lamps respectively by northern lamp level; During greasy weather and dusk, night flight or navigation at a distance, observer orientation of living in is different, has different light arrangement modes.It is entirely aobvious to locate southern eight lamps, and lamp between east and west is oblique line, and lower three lamps in the north lose.
