Ukufaka esikhundleni sokusekela kwe-strut yangaphambili ngokususa i-shock absorber nangaphandle
Okuqukethwe
Ukumiswa kohlobo lwangaphambili lweMacPherson, ngenxa yobulula bayo, ukukhiqizwa kanye nezixuku eziphansi ezingaphumi, kusheshe kuthathwe ingxenye enkulu yemakethe yezimoto kusukela engxenyeni yokugcina yekhulu lama-20. Enye yezingxenye zayo zesakhiwo, okungukuthi i-apper support bear, ibukeka njengesibonelo esihle sokuthi inzuzo ebaluleke kakhulu yohlelo, mayelana nensiza, ingashintshwa ibe yinye yezindawo zayo ezibuthakathaka.
Ngokuningiliziwe, hlobo luni lwe-node, hlobo luni lokungasebenzi kahle kwabanikazi bezimoto okufanele babhekane nakho nokuthi bangakulungisa kanjani, funda ngezansi.
Iyini i-absorber yokusekela kanye nokwesekwa kwe-strip absorber strut yangaphambili
Isisekelo sokumiswa kwekhandlela lohlobo lwe-MacPherson sihlanganisa i-shock absorber kanye nesiphethu, okungukuthi, ikhandlela elilodwa le-telescopic liyakwazi kokubili ukusebenza njengento enwebekayo futhi linciphise amandla okudlidliza komzimba okuhlobene nomgwaqo.
Ngamanye amazwi, lo mhlangano ubizwa ngokuthi "i-suspension strut" noma "i-telescopic strut".
Ukusuka ngezansi, i-rack ifakwe ngokuhlanganyela kwebhola ku-lever yokumisa, futhi ukusekelwa okuthwala kufakwe phezulu, okuvumela umzimba we-rack onesiphethu ukujikeleza mayelana ne-axis yawo ngaphansi kwethonya lenduku yokuqondisa.
Ukwesekwa okuphezulu kufaka phakathi ama-bearings aginqikayo, izindlu, izakhi zenjoloba ezimanzi kanye nezigxobo ezifakwayo.
Ngakolunye uhlangothi, umzimba uxhunywe ngokuqinile engilazini yomzimba, futhi ngakolunye uhlangothi, induku yokudonsa ukushaqeka kanye nendebe yokusekela entwasahlobo ixhunywe kuyo. Kukhona ukuzungeza phakathi kwabo.
Izinhlobo zamabhere wokusekela
I-bearing kumele yenze imisebenzi yokuxhumana ye-angular, futhi ngokunembe kakhudlwana yenza lokhu, imoto izogcina izici zayo zokuphatha isikhathi eside. Ngakho-ke, imiklamo eminingi ehlukene iye yathuthukiswa, akukho noyedwa okwamanje.
Amabhere ngokwenhlangano yawo eyakhayo angahlukaniswa abe:
- ngemvelo ye-rolling element - ibhola ne-roller;
- ama-bearings anezinhlanga ezikhishwayo zangaphandle noma zangaphakathi;
- ama-angular contact bearings ahlanganisiwe ohlobo olungahlukaniseki;
- ama-bearings angenawo amakheji, okuyikheji elinamandla elinezici ezakhelwe ngaphakathi ezigoqayo, ama-flange asekelayo asebenza njengamathrekhi.
Ngesikhathi somhlangano, ukunikezwa kwe-lubricant kufakwa ekuthwaleni, kodwa izimo zayo zokusebenza zifana nokuthi ayanele isikhathi eside.
Yini ukungasebenzi
Ngokuvamile, izimpawu zokuqala zezinkinga nge-oporniks zizoba ukumiswa kokumiswa. I-bearing eguge kakhulu futhi exegayo izoveza lo msindo kuwo wonke amaqhubu abalulekile.
Ngokuya ngomklamo, induku ye-shock absorber ingaxhunyaniswa nomjaho wangaphakathi we-bearing, noma ilungiswe nge-bushing kanye ne-raber damper emzimbeni.
Esimweni sokuqala, ukuguga okuthwalayo kuzothinta kakhulu ukulawulwa kwemoto, izilungiselelo ze-camber kanye nama-angles e-castor, ngakho-ke kungaqashelwa ngisho nangaphambi kokuba kuvele ukungqongqoza.
Njengoba sekushiwo kakade, ukubekwa uphawu komhlangano kusuka ekungcoleni komgwaqo kanye nomswakama kushiya okuningi okufanele ukwenze. Njengoba konke lokhu kunqwabelana, kugqwala kakhulu futhi kuqala ukwenza imisindo yohlobo oluhlukile, okukhumbuza ukuklabha nokuklabalasa.
Uma imininingwane enjalo idilizwa, khona-ke isithombe sizoba yisici - umgodi phakathi kweziqeshana uthathwe izingcezu ezigqwalile zamabhola angaphambili noma ama-roller.
Zenzele ngokwakho ukuxilongwa kwe-strut yangaphambili
Ukuhlola i-node esolisayo kulula kakhulu. Njengoba imoto imile, isandla esisodwa sibekwe phezu kwenduku yokudonsa ukushaqeka enentongomane ephuma enkomishini yokumiswa, kanti esinye isandla sinyakazisa umzimba. Kungcono ngisho nokwenza umsebenzi onjalo ndawonye, ngoba imizamo ibaluleke kakhulu.
Isandla esiphezu kwenkomishi yesiqu sizozwa kalula imisindo engaphandle kanye nokudlidliza, iziphi izingxenye ezisebenzisekayo okungafanele zibe nazo.
Uma umsizi ephendulela isondo lokuqondisa ukusuka kolunye uhlangothi, futhi izandla zakho, ngenkathi enkomishini yokubeka noma i-spring coil, uzizwa ungqongqoza, u-rattle (crunch), khona-ke izinto zimbi ngama-bearings.
Uma induku ye-shock absorber yemoto ethile ingaxhunywanga emncintiswaneni wangaphakathi, khona-ke kuyoba nzima ukuhlola ingxenye ngale ndlela.
Kuzodingeka ugxile kuphela emisindweni ngesikhathi sokunyakaza kanye nemiphumela yokuhlakazwa okuyingxenye kokumiswa.
Imiyalo yokushintsha i-thrust ku-VAZ imoto + ividiyo
Isibonelo, singacabangela inqubo yokukhipha nokufaka ingxenye ku-rack yemoto ye-VAZ ehamba phambili.
Ukushintshwa ngokudilizwa kwama-rack
Kulula ukusebenza ku-rack esusiwe, futhi amathuba okuba namaphutha ancishisiwe ngokufanele. Ngaphezu kwalokho, kwabaqalayo, ukubonakala kwenqubo kubaluleke kakhulu.
- Umshini uphakanyiswa ohlangothini olufunayo nge-jack futhi ubekwe endaweni ethembekile. Kuyinto engathandeki neze ukusebenza ku-jack kuphela. Isondo liyasuswa.
- Induku yokuqondisa inqanyuliwe engalweni yokugubha ye-rack, lapho i-pin nut ingaphiniwe, ivuliwe ukuphenduka okumbalwa, uxhumano lwe-conical lugxiliwe yi-mount futhi ukushaya okubukhali kusetshenziswa ngesando eceleni kwe-lug. Ukwamukela kudinga ukuqeqeshwa okuthile, kodwa ungasebenzisa njalo i-puller.
- Amabhawodi amabili aphansi we-knuckle yokuqondisa anqanyuliwe, futhi eyodwa yawo ilungisa ukusetha i-angle ye-camber, ngakho-ke lokhu kulungiswa kuzodingeka kwenziwe ekupheleni komsebenzi. Amabhawudo avame ukuba muncu, ngakho-ke into yokuthambisa engena ngaphakathi noma ngisho nethoshi ingadingeka. Bese zishintshwa zifakwe ezintsha.
- Ngokukhipha amantongomane amathathu enkomishi ngaphansi kwe-hood, ungasusa umhlangano we-rack ngaphansi kwemoto.
- Ukufaka esikhundleni sokusekela, kufanele ucindezele intwasahlobo. Izibopho ze-screw zisetshenziswa noma, enkonzweni yemoto, idivayisi ekhethekile ye-hydraulic. Ngemuva kokucindezelwa, ukusekelwa kuyakhululwa, ungakhulula i-shock absorber rod nut, ususe ukusekela futhi ubeke esikhundleni esisha, wenze yonke imisebenzi ngokuhleleka okuphambene.
Kungcono kakhulu ukusebenzisa ama-wrenches womthelela, ugesi noma i-pneumatic. Ukwenza ngokhiye abajwayelekile kungabangela ubunzima, nakuba kungenzeka.
Ukushintshwa ngaphandle kokukhipha i-rack
Uma kungekho sifiso sokwenza imisebenzi yokulungisa i-camber, futhi kukhona ukuzethemba emandleni omuntu okusebenza ngaphansi kwezimo zokufinyelela okulinganiselwe, bese ubuyisela ukusekelwa, i-rack ayikwazi ukususwa emshinini.
Kulokhu, kungcono ukukhulula i-absorber nut nut kusengaphambili, kuyilapho imoto ihamba ngamasondo futhi kukhona ukufinyelela okulula kuntongomane. Kuzoba lula kakhulu ukuyikhulula ngokuhamba kwesikhathi.
Induku yokuqondisa inqanyuliwe ngendlela efanayo, futhi ukuze ukwazi ukuhambisa i-absorber shock kuze kube phansi ngangokunokwenzeka, kuyadingeka ukukhulula ibha yokuqiniswa. Ngemva kokukhipha ukusekelwa emzimbeni, kuba nokwenzeka ukubeka ama-couplers entwasahlobo futhi wenze yonke eminye imisebenzi, njengoba kuchazwe ngenhla.
Ngesikhathi esifanayo, ama-bolts okulungisa ahlala ekhona futhi ama-angles okumiswa awashintshi.
Indlela yokuvuselela i-bearing endala nokwesekwa
Lapho kungenzeka ukusindisa inkulungwane noma ezimbili ekuthengeni izingxenye ezisele, khona-ke ubuciko bomdabu abunayo imingcele. Kudala, lokhu kwakufanele ngempela, njengoba izingxenye eziyisipele zazithuthwa ukuze zi-odwe, futhi kwakuyinde futhi ibiza.
Manje kukhona ukukhetha kukho konke ukunambitheka kanye nesabelomali, futhi izingxenye zivame ukuthengiswa ngokutholakala kwehora.
Nokho, ngezinye izikhathi ukushintshwa okukhethiwe kwezingxenye ekusekelweni kuyathetheleleka ngisho namanje. Imoto ingaba yivelakancane futhi ingavamile, futhi yonke isethi ingabiza ngokungenangqondo. Khona-ke kungenzeka ngempela ukuqaqa umhlangano wokwesekwa osusiwe, uwukhubaze ngokucophelela futhi ubuyisele izingxenye ezigugile ngempela kuphela.
Ngokuvamile kwanele ukufaka esikhundleni sokuthwala kuphela. Izinkampani eziningi zivumela lokhu, i-bearing inenombolo yayo yekhathalogi futhi ingathengwa ngokwehlukana. Noma khetha usayizi ofanele, lokhu kungenzeka futhi.
Ngenxa yalokho, ukusekelwa okubuyiselwe kuzosebenza isikhathi eside futhi akubi kakhulu kunentsha.
