Unganquma kanjani ukuthi yimaphi ama-crunches ahlangene we-CV
Okuqukethwe
Amasondo okuqondisa emoto ayinhlanganisela yamajoyinti amabili e-velocity (ama-CV joints) axhunywe umshini oneziphetho ezihlukene. Ukukhuluma ngokuqinile, umklamo ofanayo uyatholakala ku-axle yokushayela engemuva enebhokisi likagiya ku-crankcase ehlukile, kodwa ukuxilongwa kuvame ukudingeka kakhulu nge-front-wheel drive, esebenza ngaphansi kwezimo ezinzima kakhulu mayelana nama-angles okudlulisa i-torque.
Inqubo yokunquma ukuthi yimaphi amajoyinti e-CV amane asebenza lapho asegugile noma aseqalile ukuwa ivamise ukuba nzima futhi idinga ukubambelela endleleni yokusebenza enembile ukuze kugwenywe ukuchitha isikhathi nemali.
Ihlangano ye-CV yangaphandle neyangaphakathi: umehluko nezici
Ihinge yangaphandle ithathwa njengexhunywe kuhabhu lamasondo, kanti eyangaphakathi itholakala eceleni kokuphuma kwebhokisi likagiya noma i-axle reducer yokushayela.
Womabili lawa ma-node ahlukile ekwakhiweni, okuhlotshaniswa nezidingo zawo:
- ngesikhathi sokusebenza, umhlangano wedrayivu kufanele ushintshe ubude bawo ngesikhathi sokugudluzwa kokumiswa ukusuka endaweni eyodwa eyeqile ukuya kwesinye, lo msebenzi unikezwe i-hinge yangaphakathi;
- i-CV yangaphandle ehlangene ihileleke ekuqinisekiseni i-angle enkulu yokujikeleza kwesondo langaphambili, elihlinzekelwe ekwakhiweni kwalo;
- ama-splines angaphandle e-"grenade" yangaphandle aphetha ngengxenye enentambo, lapho i-nati ifakwe khona, iqinisa izinhlanga zangaphakathi zokuthwala isondo;
- isiphetho se-spline ngaphakathi kwedrayivu singase sibe ne-annular groove yendandatho yokugcina, noma sibe nokulingana okuxekethile, i-shaft ibanjwe ku-crankcase ngezinye izindlela;
- ihinge yangaphakathi, ngenxa yokuphambuka kwayo okuncane kuma-engeli, kwesinye isikhathi ayenziwa ngokohlelo lwakudala lwamabhola ayisithupha, kodwa isesimweni se-tripoid, okungukuthi, izikhonkwane ezintathu nezinenaliti ezinemijaho yangaphandle eyindilinga. iqinile, ihlala isikhathi eside, kodwa ayisebenzi kahle kuma-engeli abalulekile.
Uma kungenjalo, ama-node ayafana, womabili ahlanganisa umzimba onemifantu yamabhola noma ama-spikes, ikheji elingaphakathi, ama-splines ahlezi ku-drive shaft kanye nesihlukanisi esibeka amabhola lapho sigijima emiseleni esebenzayo.
Izimbangela nezimpawu zokuhluleka kwamalunga esivinini esingashintshi
Isizathu esiyinhloko sokuhluleka kwe-hinge ukugqokwa kwama-grooves kokubili iziqeshana, isihlukanisi namabhola. Lokhu kungenzeka ngokwemvelo, okungukuthi, phambi kokugcoba kwekhwalithi ephezulu isikhathi eside, ngaphezu kwamakhulu ezinkulungwane zamakhilomitha noma asheshisiwe.
Ukuguga okusheshayo kuqala ngokungena kwama-abrasives noma amanzi kukhava yokunwebeka eyisivikelo. Ngesengezo esinjalo ku-lubricant, umhlangano uhlala amakhilomitha ayinkulungwane noma ngaphansi. Khona-ke izimpawu zokuqala zezinkinga ziqala ukuvela.
Uma amabhola egijima, womabili amakheji asebenzisana ncamashi nezikhala ezincane. Ama-trajectories aginqikayo nashelelayo alungiswa kahle, ngokuvamile ngisho nangokukhetha okukhethiwe kwezingxenye. Ihinji enjalo isebenza buthule lapho idlulisela noma iyiphi i-torque elinganiselwe futhi kunoma iyiphi i-engeli ukusuka ebangeni elinikeziwe.
Ngokushesha lapho izikhala zanda ngenxa yokugqoka noma i-geometry ye-grooves ihlanekezelwe, ukungqongqoza kubonakala ku-hinge ngenxa yokukhethwa kwama-backlashes kanye nama-crunches ngenxa yomshado wendawo. Ukudluliswa kwe-torque kwenzeka ngama-jerks wamazinga ahlukahlukene okubonakala.
Ungahlola kanjani ukujoyina kwe-CV yangaphandle
Isimo esinzima kakhulu sengxenye yangaphandle yedrayivu kuzoba ukudlulisa i-torque enkulu nge-engeli ephezulu. Okusho ukuthi, uma i-hinge igugile, khona-ke inani eliphakeme le-backlash ne-acoustic accompaniment lifinyelelwa ngokunembile kumamodi anjalo.
Ngakho indlela yokuthola:
- lapho ushayela ngesivinini esiphansi, amasondo aphendulwa yonke indlela eya endaweni ephakeme kakhulu futhi kwenziwa ukusheshisa okubukhali, i-crunch izozwakala kusukela ekuhlanganyeleni okungalungile kwe-CV;
- ngokuphinda inqubo kuzo zombili izinkomba, iziphetho zicacisiwe, kuyilapho kuqondwa ukuthi i-engeli yokujikeleza kwesondo elingaphakathi elihlobene ne-trajectory yesondo inkulu kuneyangaphandle;
- uma kwenzeka ungabaza, imoto ilengiswe ekuphakameni, zonke lezi zenzo ziyaphindwa, futhi i-diagnostician engaphansi kwemoto ilalela ama-node athile, umthwalo odingekayo ulingiswa ngokucindezela kanyekanye i-accelerator kanye nama-brake pedals.
Ukuxilongwa kokugcina kwenziwa ngemva kokukhipha idrayivu emshinini nokunqamula amahinge kuwo. Ukuhlehla kuzobonakala ngokucacile lapho ikheji yangaphandle inyakaza ngokuhlobene nengaphakathi, ukugqokwa kwe-groove kubonakala ngemva kokuhlakazeka nokususwa kwamafutha, futhi imifantu kusihlukanisi ibonakala ngokucacile endaweni yayo eqinile.
Ihlola "ibhomu" langaphakathi
Uma uhlola ohambweni, ukuhlanganyela kwangaphakathi kufanele futhi kudalwe ngenxa yezimo ezimbi kakhulu zokusebenza, okungukuthi, ama-angles aphezulu. Akukho okuncike ekuphenduleni isondo lokuqondisa lapha, ngakho-ke uzodinga ukugoqa imoto ngangokunokwenzeka, uhamba nge-arc ngesivinini esikhulu ngaphansi kokudonsa okugcwele.
I-crunch esuka ngaphakathi emotweni ehlobene ne-trajectory izosho ukuguga endaweni engaphakathi kule drayivu ethile. Uhlangothi oluphambene, ngokuphambene nalokho, luzonciphisa i-angle yekhefu, ngakho-ke i-crunch ingavela lapho kuphela kusuka ku-node esesimweni esibucayi ngokuphelele.
Ukuhlolwa ku-lift kungakhiwa ngendlela efanayo, ukulayisha idrayivu ngamabhuleki, futhi uguqule ama-engeli okuthambekela kwezingalo ezilengayo usebenzisa ama-hydraulic props. Ngesikhathi esifanayo, kulula kakhulu ukuhlola ubukhona be-backlashes kanye nesimo sesembozo. Ama-anther adabukile isikhathi eside anokungcola nokugqwala ngaphakathi kuyosho ukuthi ihinge kufanele ishintshwe ngokusobala.
Kungani i-crunch iyingozi?
Ihinji eqinile ngeke ihlale isikhathi eside, imithwalo enjalo izoyibhubhisa ngenani elikhulayo. Insimbi iyakhathala, imbozwe inethiwekhi yama-microcracks kanye ne-pitting, okungukuthi, ukucwiliswa kwezindawo zokusebenza zamathrekhi.
Ikheji eliqinile kodwa eliqinile lizomane liqhekeke, amabhola azoziphatha ngokungahleliwe futhi i-hinge izogxuma. Idrayivu izobhujiswa futhi ukunyakaza okuqhubekayo kwemoto kuzokwenzeka kuphela elolini elidonsayo, futhi ukulahlekelwa ukudonsa ngesivinini esikhulu nakho akuphephile.
Khona manjalo kungase kube khona ukungasebenzi kahle kuka-gearbox oshaywe wu-drive shaft.
Kungenzeka yini ukulungisa i-CV ehlangene noma nje ukushintshwa
Eqinisweni, ukulungiswa kwe-CV ehlangene akunakwenzeka ngenxa yokunemba okuphezulu kokukhiqizwa kwayo, okusho ukukhethwa kwezingxenye. Ihinge eqoqwe ezingxenyeni ezihlukene izokwazi ukusebenza ngandlela thize, kodwa asikho isidingo sokukhuluma ngokungabi namsindo nokuthembeka.
Umhlangano ogugile kuzodingeka ushintshwe njengomhlangano, njengoba ama-spline ku-shaft nawo aguga, ngemva kwalokho umhlangano uzongqongqoza ngisho namahinge amasha. Kodwa kubiza kakhulu, ngakho-ke kunikezwa kuphela abakhiqizi bezingxenye ezisele zangempela.
Ama-analogue angahlinzekwa ngendlela yamakhithi asuka ngqo ejoyintini le-CV, i-anther, izinsimbi zensimbi kanye namafutha akhethekile ngenani elifanele.
