Ezimotweni eziningi ezifuywayo (kanye nasezimotweni eziningi ezenziwe kwamanye amazwe), kusetshenziswa uhlelo lwendabuko lokushayela i-speedometer kusuka ku-gearbox usebenzisa i-shaft ekhethekile eguquguqukayo.Funda mayelana nokuthi iyini i-speedometer shaft eguquguqukayo, ukuthi isebenza kanjani nokuthi isebenza kanjani kulesi sihloko.
Iyini i-flex speedometer shaft?
I-shaft eguquguqukayo ye-speedometer iyisici sokushayela kwe-speedometers yezimoto ezinomshini kanye ne-electromechanical.Umsebenzi we-shaft eguquguqukayo ukudlulisa i-torque isuka ku-shaft yesibili ye-gearbox iye kuyunithi yesivinini kanye ne-odometer ye-speedometer.Futhi, le ngxenye ixazulula izinkinga ezimbalwa zobuchwepheshe nesakhiwo, isibonelo, iqinisekisa ukusebenza okuvamile kwe-speedometer kungakhathaliseki ukuthi ikuphi isikhundla sayo esihlobene ne-gearbox, ikuvumela ukuba ulahle amagiya aqinile, njll.
Emashumini amabili eminyaka adlule, amashafu we-speedometer ashintshashintshayo alahlekelwe kakhulu indawo yezinzwa zejubane nama-speedometer kagesi, kodwa ukuhanjiswa okuguquguqukayo kusasetshenziswa kabanzi ezimotweni ezingabizi kanye nasembonini yezimoto yasekhaya.I-speedometer engumshini noma ye-electromechanical ene-flexible shaft drive iyindlela elula futhi eshibhile yokukala isivinini, ngakho-ke akunakwenzeka ukuthi ishintshwe ngokuphelele ngamadivaysi kagesi eminyakeni ezayo.
Ngabe i-shaft eguquguqukayo ye-speedometer isebenza kanjani?
I-shaft eguquguqukayo inomshini ongeyona inkimbinkimbi kakhulu.Isisekelo se-shaft yikhebula lensimbi, elisontekile kusuka ezingxenyeni ezintathu, ezine noma ezinhlanu zocingo oluyindilinga (ikhebula libuye libe nomgogodla wensimbi, lapho ucingo lulima khona).Zombili iziphetho zekhebula zine-square cross-section enohlangothi lwe-2, 2.6 noma 2.7 mm ubude obungu-20-25 mm - ngesikwele, ikhebula lixhunywe ku-drive kanye ne-speedometer.
Ikhebula libekwe endaweni yokuvikela izikhali (noma nje izikhali zempi) - ishubhu eliguquguqukayo elisontekile ngensimbi enenxeba elivunguzayo noma itheyiphu yepulasitiki.Ukuvikelwa kwezikhali kwe-2/3 yobude kugcwele amafutha ohlobo lwe-Litol - lokhu kuqinisekisa ukujikeleza kwayo okufanayo kwekhebula ngaphandle kwe-jamming, kanye nokuvikelwa kokugqwala.Isembatho zempi sona sinento evikelayo eyenziwe nge-PVC, i-polyethylene noma irabha engamelana nowoyela.Iziphethu zokuzivikela zingatholakala ku-shaft, kanye ne-rubber cuffs eyodwa noma ngaphezulu (bushings) ukuvikela emonakalweni wegobolondo le-shaft lapho udlula emigodini yezakhi zesakhiwo semoto.
Emaphethelweni okuvikela izikhali, izingono zinamathele ngokuqinile - izingxenye ze-conical lapho amantongomane enyunyana atholakala ukuze ahlanganiswe nebhokisi le-gearbox kanye ne-speedometer.Amantongomane nezingono zingenziwa ngepulasitiki noma ngensimbi.Ohlangothini luka-gearbox, inati linosayizi omkhulu.Ngakolunye uhlangothi lwekhebula kukhona iwasha yokukhiya (eyandiswayo), ehlala ehlombe ngaphakathi kwengono, futhi ivimbele ukugudluka kwekhebula ngaphakathi kwezikhali (kuyadingeka futhi ukusevisa i-shaft - ngemuva kokukhipha i-washer. , ungakhipha ikhebula bese ugcwalisa izikhali ngamafutha).
Izici nokuklama kwama-shafts aguquguqukayo akhiqizwa eRussia alawulwa yi-GOST 12391-77 ejwayelekile.Ngokuhambisana nendinganiso, izimoto nezithuthuthu zifakwe ama-shaft aguquguqukayo ama-speedometer anokujikeleza kwesokunxele kohlobo olugoqekayo (ngekhebula elikhiphekayo, njengoba kushiwo ngenhla) ngezinhlobo ezimbalwa zokuxhuma kusuka ku-gearbox kanye ne-speedometer (kanye. njengama-shafts ngokwawo, izisekelo zokuxhuma zokufakwa kwazo zilinganiselwe).Ubude be-shafts bungaba kusuka ku-530 mm kuya kumamitha amaningana, kodwa ama-shafts asetshenziswa kakhulu asuka ku-1 kuya ku-3.5 amamitha ubude.
Ngabe ishaft ye-speedometer eguquguqukayo isebenza kanjani?
I-shaft isebenza kalula.Lapho imoto ihamba, i-torque evela ku-shaft yesibili ye-gearbox idluliswa ngegiya kanye nedivayisi yokubopha iye ekupheleni kwentambo ye-shaft.Ikhebula, ngenxa yomklamo walo, linokuqina okuphezulu kwe-torsional (kodwa kuphela ngokuzungeza kwesokunxele, ngokuzungeza okuhlanekezelayo iqala ukukhululeka futhi ingabhajwa ngaphakathi kwezikhali), ngakho-ke lapho umkhawulo owodwa usontekile, uthola ukuzungezisa ubude bawo bonke.Ngaphezu kwalokho, ikhebula lijikeleza lilonke, ngakho-ke ukuguqulwa kwejubane lokujikeleza kwe-shaft yesibili ye-gearbox cishe kuthinta ngokushesha ushintsho ekujikelezeni kwe-drive yenzwa yesivinini semoto ku-speedometer.Ngakho-ke, i-torque evela egiyeni ku-gearbox ihlale idluliswa yikhebula le-shaft eguquguqukayo liye kumhlangano wesivinini se-speedometer, futhi umshayeli unamandla okulandelela isivinini semoto.
Ngokuhamba kwesikhathi, ikhebuli ilahlekelwa izici zayo zamandla, iziphetho zayo zesigaba sesikwele kanye nesokhethi iphuka (ilahlekelwa i-geometry), futhi idinga ukushintshwa.Kodwa-ke, ukushintshwa nokulungiswa akudingekile kaningi - insiza ye-shafts eguquguqukayo kuze kube ngamamitha angu-2 ubude okungenani izinkulungwane eziyi-150 km, imigodi ende - okungenani izinkulungwane ezingama-75 km.
Uma kwenzeka ukugqoka noma ukuphuka, i-shaft eguquguqukayo ye-speedometer idinga ukushintshwa, futhi lokhu kufanele kwenziwe ngokushesha ngangokunokwenzeka - ukusebenza kwemoto ene-speedometer engasebenzi akuvunyelwe yimithetho yomgwaqo (isigaba 7.4 se-" Uhlu lokungasebenzi kahle nezimo lapho ukusebenza kwemoto kuvinjelwe").Futhi nakuba, ngokomthetho, i-speedometer engalungile ayikwazi ukubangela izinhlawulo, noma kunjalo, lokhu kuphazamiseka kwenza kube nzima ukuthola ikhadi lokuxilonga, futhi kungabangela ukwephulwa komkhawulo wejubane - futhi ukwephulwa okunjalo kakade kujeziswe yizinhlawulo futhi kungaba nokunye okwengeziwe. imiphumela emibi.
