Uyini ubakaki ofakwa ngaphambili
Ubakaki ofakwe ngaphambili ngokuvamile ubhekisela kubakaki abafakwe ngaphambi kwemoto, ikakhulukazi abasetshenziselwa ukusekela nokulungisa izingxenye zangaphambili zemoto, njengobhampa, ugongolo oluvimbela ukushayisana, njll., ukuze kuqinisekiswe ukuthi lezi zingxenye zingaxhunywa ngokuqinile emzimbeni wemoto, ngaleyo ndlela kuthuthukiswe ukuphepha nokuzinza kwemoto.
Isakhiwo nomsebenzi
Ubakaki ofakwe ngaphambili ngokuvamile wenziwa ngezinto zensimbi ezinamandla amakhulu nokumelana nokugqwala. Idizayini yabo ngokuvamile ihlanganisa izindawo eziningi zokuxhuma ukuze kuqinisekiswe ukusatshalaliswa okuphumelelayo kwamandla omthelela uma kwenzeka kushayisana, ukuvikela ukuphepha kwemoto nabagibeli. Ngaphezu kwalokho, laba bakakaki baphinde babambe iqhaza ekuhlobiseni ukubukeka kwemoto, okwenza imoto ibukeke icocekile futhi ihambisana kangcono.
Indlela yokufaka
Ukufaka ibha yangaphambili Ukufaka usekelo kudinga ulwazi oluthile lochwepheshe namakhono. Ngokuvamile kuyadingeka ukususa izingxenye zangaphambili zemoto, njengebhampa, bese ufaka ubakaki endaweni ecacisiwe. Inqubo yokufaka idinga ukusetshenziswa kwamathuluzi afanelekile nezixhumi ukuze kuqinisekiswe ukuzinza nokuphepha kukabakaki. Ngemuva kokuthi ukufakwa sekuqediwe, kuyadingeka futhi ukwenza izinguquko ezidingekayo kanye nokuhlolwa ukuze kuqinisekiswe ukuthi ukusekela kusebenza kahle.
Iqhaza labakaki abafakwa ngaphambili emotweni ikakhulukazi lihlanganisa izici ezilandelayo :
ukulungisa nokuthambisa : Abakaki abafaka ibha yangaphambili (njengabakaki be-torque kanye neglue onyaweni lwenjini) basebenza njengokulungisa nokuthambisa ngokuxhuma umzimba enjinini. I-adhesive esekela i-torque inganciphisa ukudlidliza nomsindo okhiqizwa ngesikhathi sokusebenza kwenjini, ithuthukise ukunethezeka kwemoto, futhi idlale indima yokuqinisa phakathi kwenjini nezingxenye ezixhumayo zomzimba, inwebe impilo yesevisi yezingxenye.
Amandla okudlulisa : Ubakaki ofakwe ngaphambili nawo unesibopho sokudlulisa amandla enjini. Ngemuva kokuthi amandla enjini ecutshungulwe yi-clutch kanye no-gearbox, idluliselwa esondo lokugcina eliphumayo nge-axle yangaphambili, ukuze imoto ikwazi ukugijima ngendlela evamile.
isisindo esithwalayo : ubakaki ofaka ibha yangaphambili ixhunywe ne-axle yangaphambili ngomshini wokuxhuma ukuze ithwale isisindo somzimba futhi iqinisekise ukuhamba kahle kwemoto.
thuthukisa ukusebenza kwe-NVH : Umhlangano wabakaki osuselwe kubakaki bokumiswa kwe-axle yangaphambili unomsindo omuhle kakhulu nokusebenza kokunciphisa ukushaqeka, okungathuthukisa izici ze-NVH zemoto, kugweme ukuguquguquka kwezinhlangothi zombili ze-U-frame ngaphansi kwamandla angaphandle, futhi kuqinisekiswe ukusebenza okuzinzile nokushayela ngokunethezeka kwemoto.
Amahhanisi nezixhumanisi ezivikelayo : Ezinye izisekelo zokukhweza ngaphambili (njengamahhanisi okulungisa izintambo osilingi wezimoto) zinesakhiwo esilula futhi zihlanganisiwe, ezidlala indima enhle ekuvikeleni nasekulungiseni amahhanisi nezixhumi zezintambo. Qinisekisa ukuthi ukuqina kokufakwa kwamahhanisi ezintambo kuhle futhi akulula ukukhiqiza umsindo ongajwayelekile .
Ukwehluleka kukabakaki okufakwayo ngaphambili ngokuvamile kubhekisela ezinkingeni ezenzeka phakathi nokufakwa okungabangela ukuba ubakaki ungasebenzi kahle noma uphazamise ukusebenza kwawo. Izimbangela eziqondile nezisombululo zimi kanje:
amandla angalingani kumabhawodi : Uma amabhawodi asetshenziswa ukulungisa uhlaka lwenjini kulula ukuphuka, ngokuvamile kusho ukuthi amandla kumabhawodi awalingani. Lokhu kungase kube ngenxa yokuguquguquka endaweni ehlobene phakathi kwenjini nomzimba, ngokuvamile ngenxa yokonakala kwentambo yangaphambili okubangelwe ingozi engakalungiswa ngokugcwele.
ukutheleleka kwendawo : Ngemva kokuhlinzwa kwe-stent yegatsha eliwela ngaphambili, uma unganaki inhlanzeko yendawo, kulula ukubangela ukutheleleka kwendawo.
ukopha emathunjini : ukusetshenziswa kwezidakamizwa zokuhlanganisa amaplatelet ngemva kokuhlinzwa kungase kuholele ekwehleni kokusebenza kwe-coagulation kanye nokulimala kwe-mucosa yesisu, okuholela ekuphumeni kwegazi emathunjini.
i-thrombosis : imicu ye-collagen engaphansi ingase yonakaliswe ngesikhathi sokuhlinzwa, okuholela ekuhlanganisweni kweplatelet nokunamathela endaweni yangakini, kwakheke i-thrombus.
I-myocardial ischemia : uma indlela yokuphila engeyinhle ingathuthukisiwe ngemva kokuhlinzwa, umfutho wegazi, i-lipid noshukela wegazi kungalawuleki, kungase kubangele i-stent thrombosis, ngisho ne-myocardial ischemia ezimweni ezimbi kakhulu.
Iziphakamiso zokuvimbela nokugcinwa kwamaphutha
ukugcinwa njalo : ukugcinwa njalo kosekelo, kuqinisa umsebenzi wokuphatha wansuku zonke, ukugwema ukwenzeka kokwehluleka.
gcina inhlanzeko : qaphela inhlanzeko yendawo ngemva kokuhlinzwa ukuze ugweme ukutheleleka kwendawo.
thuthukisa indlela yokuphila : gcina isimo sengqondo esihle nemikhuba yokuphila, ubhekane nesimo ngentshiseko, ulawule umfutho wegazi, i-lipid noshukela egazini.
Izinhlelo eziphuthumayo : Yenza izinhlelo eziphuthumayo ukuze uqinisekise ukusabela okusheshayo kanye nokwelashwa uma kwenzeka ukwehluleka okukhulu.
