Kwiimoto ezininzi zasekhaya (kunye neemoto ezininzi ezenziwe kwamanye amazwe), isikimu semveli sokuqhuba isantya kwibhokisi yegiya kusetyenziswa ishaft ekhethekileyo eguquguqukayo.Funda malunga nokuba yiyiphi i-speedometer shaft eguquguqukayo, isebenza njani kwaye isebenza njani kweli nqaku.
Yintoni ishaft ye-flex speedometer?
I-shaft eguquguqukayo ye-speedometer yinto yokuqhuba i-speedometers ye-mechanical and electromechanical automotive.Umsebenzi we-shaft eguquguqukayo kukudlulisa i-torque ukusuka kwi-shaft yesibini yebhokisi yegiya ukuya kwiyunithi yesantya kunye ne-odometer yesantya.Kwakhona, le nxalenye isombulula iingxaki ezininzi zobugcisa kunye nolwakhiwo, umzekelo, iqinisekisa ukusebenza okuqhelekileyo kwe-speedometer kungakhathaliseki ukuba injani indawo yayo kwibhokisi yegiya, ikuvumela ukuba ulahle iigiya eziqinileyo, njl.
Kule minyaka ingamashumi amabini idlulileyo, iishafti eziguquguqukayo ze-speedometer shafts ziphulukene kakhulu nomhlaba we-speed sensors kunye ne-electronic speedometers, kodwa ukuhanjiswa okuguquguqukayo kusasetyenziswa ngokubanzi kwiimoto ezingabizi kakhulu kunye neshishini lemoto yasekhaya.I-speedometer yomatshini okanye ye-electromechanical ene-flexible shaft drive yeyona ndlela ilula kwaye inexabiso eliphantsi yokulinganisa isantya, ngoko ke akunakwenzeka ukuba ithathelwe indawo ngokupheleleyo zizixhobo zombane kwiminyaka ezayo.
Ingaba ishafti eguquguqukayo yesixhobo sokulinganisa isantya sisebenza njani?
I-shaft eguquguqukayo inesixhobo esingenzima kakhulu.Isiseko se-shaft yintambo yensimbi, ephothiweyo ukusuka kumacandelo amathathu, amane okanye amahlanu ocingo olujikelezayo (ikhebula libuye libe nentsimbi yentsimbi, apho ucingo lulimala).Zombini iziphelo zekhebula zine-square cross-section kunye necala le-2, 2.6 okanye 2.7 mm ubude be-20-25 mm - ngendlela yesikwere, ikhebula lixhunyiwe kwi-drive kunye ne-speedometer.
Intambo ibekwe kwindawo yokukhusela isikrweqe (okanye isikrweqe nje) - ityhubhu eguquguqukayo ejijekileyo kwisinyithi esinenxeba elijikelezayo okanye iteyiphu yeplastiki.Ukukhuselwa kwezixhobo ze-2/3 zobude kuzaliswe ngegrisi yohlobo lweLitol - oku kuqinisekisa ukujikeleza kwayo okufanayo kwentambo ngaphandle kwe-jamming, kunye nokukhuselwa kwe-corrosion.Isikrweqe, sinokhuselo olukhuselayo olwenziwe nge-PVC, i-polyethylene okanye i-rubber engamelana neoli.Imithombo yokukhusela inokufumaneka kwi-shaft, kunye ne-rubber cuffs enye okanye ngaphezulu (i-bushings) ukukhusela umonakalo kwigobolondo le-shaft xa udlula emigodini kwizinto zesakhiwo semoto.
Ekupheleni kokhuselo lwezixhobo, iingono zincanyathiselwe ngokuqinileyo - iindawo ezinqamlezileyo apho amantongomane omanyano abekwe khona ukuze ancamathele kwibhokisi yegiya kunye nesantya.Amandongomane kunye neengono zingenziwa ngeplastiki okanye ngentsimbi.Kwicala lebhokisi yegiya, indongomane inobukhulu obukhulu.Kwelinye icala lentambo kukho ukutshixa (ukwandisa) iwasha, ehlala egxalabeni ngaphakathi kwingono, kwaye ithintela ukufuduka kwentambo ngaphakathi kwesikrweqe (kuyafuneka kwakhona kwinkonzo yeshaft - emva kokususa iwasha). , unokukhupha ikhebula kwaye ugcwalise isikrweqe ngegrisi).
Iimpawu kunye noyilo lweeshafu eziguquguqukayo ezenziwe eRashiya zilawulwa ngumgangatho weGOST 12391-77.Ngokuhambelana nomgangatho, iimoto kunye nezithuthuthu zixhotyiswe ngeeshafu eziguquguqukayo ze-speedometers kunye nokujikeleza kwesandla sasekhohlo sohlobo oluqengqelekayo (kunye nentambo esuswayo, njengoko kukhankanyiwe ngasentla) kunye neendidi ezininzi zoqhagamshelo olusuka kwibhokisi yegiya kunye nesantya (kunye. njengama-shafts ngokwawo, iziseko zokudibanisa zofakelo lwazo zisemgangathweni).Ubude bama-shafts bunokuvela kwi-530 mm ukuya kwiimitha ezininzi, kodwa i-shafts esetyenziswa ngokuqhelekileyo isuka kwi-1 ukuya kwi-3.5 yeemitha ubude.
Ingaba ishafti yesantya esiguquguqukayo isebenza njani?
I-shaft isebenza ngokulula.Xa isithuthi sihamba, i-torque esuka kwi-shaft yesibini ye-gearbox ihanjiswa nge-gear kunye nesixhobo sokuqinisa ukuya ekupheleni kwentambo ye-shaft.Intambo, ngenxa yoyilo lwayo, inokuqina okuphezulu kwe-torsional (kodwa kuphela ngokujikeleza ngasekhohlo, ngokujikeleza okubuyela umva iqala ukuphumla kwaye inokubambeka ngaphakathi kwesikrweqe), ke xa isiphelo esinye sijijekile, sijikeleza ngobude bayo bonke.Ngaphezu koko, intambo ijikeleza iyonke, ngoko ke utshintsho kwisantya sokujikeleza kwe-shaft yesibini ye-gearbox phantse ichaphazela kwangoko utshintsho ekujikelezeni kwe-speed sensor kwi-speedometer.Ke, i-torque esuka kwigiya kwibhokisi yegiya ihlala ihanjiswa ngentambo ye-shaft eguquguqukayo ukuya kwindibano yesantya sesantya, kwaye umqhubi unamandla okulandelela isantya semoto.
Ngokuhamba kwexesha, ikhebula lilahlekelwa yimpawu zamandla, iziphelo zalo zecandelo lesikwere kunye neziseko zokuphuka (ukulahlekelwa yijometri), kwaye zifuna ukutshintshwa.Nangona kunjalo, ukutshintshwa kunye nokulungiswa akufuneki rhoqo-umthombo weeshafu eziguquguqukayo ukuya kwi-2 yeemitha ubude ubuncinci be-150 yeekhilomitha eziliwaka, i-shafts emide - ubuncinane i-75 yeekhilomitha eziliwaka.
Kwimeko yokugqoka okanye ukuphuka, i-shaft eguquguqukayo ye-speedometer kufuneka itshintshwe, kwaye oku kufuneka kwenziwe ngokukhawuleza - ukusebenza kwemoto ene-speedometer engasebenziyo akuvumelekanga yimithetho yendlela (umhlathi 7.4 we " Uluhlu lokungasebenzi kakuhle kunye neemeko apho ukusebenza kwesithuthi kuthintelwe").Kwaye nangona, ngokomthetho, i-speedometer ephosakeleyo ayinakubangela izohlwayo, nangona kunjalo, oku kuphuka kwenza kube nzima ukufumana ikhadi lokuxilonga, kwaye kunokubangela ukuphulwa komda wesantya - kwaye ulwaphulo olunjalo sele luhlawuliswa ngezohlwayo kwaye lunokuba lukhulu. iziphumo ezibi.
