Chogwirira cha thunthu la galimoto: Udindo wofunikira pakuteteza thunthu la galimoto
Pakati pa zigawo zambiri za galimoto, hinge ya trunk ingawoneke ngati yosafunika kwenikweni, koma imagwira ntchito yofunika kwambiri poonetsetsa kuti trunk itseguka bwino komanso kuti zinthu zomwe zili mkati mwake zikhale zotetezeka. Ili ngati "cholumikizira" cha trunk ya galimoto, chomwe chimathandizira mwakachetechete kutsegula ndi kutseka kulikonse panthawi yogwiritsidwa ntchito tsiku ndi tsiku ndipo ndi gawo lofunika kwambiri pa kapangidwe ka thupi la galimotoyo.
Ntchito yaikulu ya hinge ya thunthu la galimoto
Chogwirira cha thunthu la galimoto ndi chipangizo chofunikira kwambiri chomwe chimalumikiza chivundikiro cha thunthu ndi thupi la galimoto. Ntchito yake imakhudza mbali zonse za kagwiritsidwe ntchito ka thunthu, makamaka mbali zotsatirazi:
Kuzindikira ntchito yotsegulira ndi kutseka, kuonetsetsa kuti ntchitoyo ikugwiritsidwa ntchito mosavuta
Ntchito yofunikira kwambiri ya hinge ya trunk ndikulola chivundikiro cha trunk kutseguka mosavuta komanso pafupi ndi thupi la galimoto. Kaya ndi posungira katundu paulendo watsiku ndi tsiku kapena kutenga zida panthawi yokonza galimoto, ntchito yosalala ya hinge imadalira. Mitundu yosiyanasiyana ya trunk ili ndi mapangidwe osiyanasiyana a hinge, monga ma hinge a single-point ndi ma hinge a link-type. Hinge ya single-point ili ndi kapangidwe kosavuta komanso mtengo wotsika, yokhala ndi malo ozungulira okhazikika, omwe angakwaniritse zofunikira zoyambira zotsegulira ndi kutseka; hinge ya link-type ili ndi malo ozungulira osunthika, omwe amapereka ufulu waukulu wa mawonekedwe a kutsogolo ndi kumbuyo kwa chivundikiro cha trunk, komanso kuonetsetsa kuti ngodya yayikulu yotsegulira, zomwe zimapangitsa kuti ogwiritsa ntchito azitha kutenga ndikuyika zinthu mosavuta, monga ngodya yotsegulira chivundikiro cha trunk ya Audi 100 imatha kufika 87°.
Pa mitundu ya sedan, hinge yokhala ndi torsion bar nthawi zambiri imagwiritsidwa ntchito. Trunk lock ikatsegulidwa, trunk cover imatseguka yokha mpaka pamalo okhazikika pansi pa ntchito ya torsion bar, zomwe zimapangitsa kuti pasakhale kufunikira kokweza ndi manja; pomwe pa mitundu ya hatchback, chifukwa cha kuchuluka ndi kulemera kwa trunk cover, kasupe wa mpweya nthawi zambiri amaphatikizidwa ngati chothandizira chothandizira kuti chikhale chofanana ndi trunk cover, zomwe zimapangitsa kuti kutsegula ndi kutseka kukhale kosavuta.
Kupereka chithandizo chokhazikika, kuonetsetsa kuti zinthuzo ndi zotetezeka
Chogwirira cha thunthu chiyenera kunyamula kulemera kwa chivundikiro cha thunthu, kuonetsetsa kuti chili chokhazikika potsegula ndi kutseka, komanso kupewa kugwedezeka mwangozi. Chogwirira cha thunthu chikatsegulidwa, chogwiriracho chiyenera kukhala chokhoza kuthandizira bwino chivundikiro cha thunthu, kupewa kugwa mwadzidzidzi chifukwa cha kulemera kwake kapena mphamvu zake zakunja, zomwe zimayambitsa kuvulala kapena kuwonongeka kwa zinthu. Chogwirira chapamwamba chimapangidwa ndi zipangizo zolimba kwambiri ndipo chili ndi mphamvu yabwino yonyamula katundu komanso kulimba, zomwe zimapangitsa kuti chigwire ntchito bwino ngakhale chitakhala chogwiritsidwa ntchito kwa nthawi yayitali kapena kunyamula zinthu zolemera.
Kuphatikiza apo, chivundikiro cha thunthu chikatsekedwa, hinge imatha kuonetsetsa kuti chikugwirizana bwino ndi thupi la galimoto, kukulitsa kutseka kwa thunthu, kuchepetsa phokoso la mphepo ndi zoopsa za mvula, komanso kuteteza bwino zinthu zomwe zili mkati ku zinthu zakunja zachilengedwe.
Kusintha malinga ndi chitukuko cha magetsi, kukulitsa luso lanzeru
Ndi chitukuko cha ukadaulo wamagetsi wamagalimoto, mitundu yambiri ili ndi ma trunk amagetsi. Mosiyana ndi ma hinge achikhalidwe ogwiritsidwa ntchito pamanja, hinge yamagetsi yamagetsi iyenera kusinthidwa kuti igwirizane ndi makina oyendetsa magetsi, kugwiritsa ntchito mphamvu kuchokera kumapeto othandizira kuti ayendetse trunk kuti itsegule ndi kutseka yonse. Pakupanga magetsi, ma hinge anayi a dongosolo la trunk ayenera kukonzedwa bwino, kuwonjezera kutalika kwa mkono wamagetsi, kuchepetsa mphamvu yofunikira pa kuyendetsa magetsi, kuti zitsimikizire kuti kutsegula ndi kutseka kwamagetsi kukuyenda bwino komanso kudalirika. Kudzera munjira zaukadaulo monga kuyerekezera kwamphamvu, ndizotheka kupeza molondola momwe makinawo amayendera komanso momwe makinawo amagwirira ntchito pamalo aliwonse, kupereka chithandizo cha data cha kapangidwe kabwino ka hinge.
Zolakwika ndi mayankho wamba a ma hinge a trunk ya galimoto
Ngakhale kuti hinge ya thunthu la chinthucho yapangidwa kuti ikhale yolimba komanso yolimba, ikagwiritsidwa ntchito kwa nthawi yayitali, ikakhudzidwa ndi zinthu zachilengedwe komanso ntchito, zolakwika zosiyanasiyana zimatha kuchitika, zomwe zimakhudza kugwiritsa ntchito bwino kwa thunthu. Zolakwika ndi mayankho wamba ndi awa:
Kumasula hinge
Kutsegula ndi kutseka chivundikiro cha trunk kwa nthawi yayitali, kuyendetsa galimoto m'misewu yodzaza ndi mikwingwirima, ndi zina zotero, kungayambitse kuti mabotolo olumikizira a hinge asuzuke, zomwe zimapangitsa kuti chivundikiro cha trunk chigwedezeke komanso kuti kutsegula ndi kutseka kusagwire bwino ntchito. Yankho lake ndikugwiritsa ntchito wrench ya torque kuti mugwiritse ntchito torque yokhazikika (15 - 20N·m) kuti mulimbikitse mabotolo, ndikutsimikizira kulumikizana kotetezeka pakati pa hinge ndi thupi la galimoto ndi chivundikiro cha trunk.
Dzimbiri ndi dzimbiri la hinge Galimoto imakhala panja kwa nthawi yayitali, ikukumana ndi mphepo ndi mvula. Ma hinge amakhala ndi dzimbiri komanso dzimbiri, zomwe zimapangitsa kuti kutseguka ndi kutseka kukhale kovuta komanso kutsekeka. Pa dzimbiri laling'ono, chochotsera dzimbiri cha phosphoric acid chingagwiritsidwe ntchito pochiza. Mukachotsa dzimbiri, ikani mafuta kapena mafuta odzola kuti mubwezeretse kusalala kwa ma hinge. Ngati dzimbirilo ndi lalikulu ndipo limakhudza ntchito yachizolowezi ya ma hinge, ndikofunikira kuganizira zosintha ma hinge atsopano.
Kuwonongeka kwa bere
Ma bearing omwe ali mkati mwa ma hinges akhoza kuwonongeka chifukwa cha kuwonongeka ndi mafuta ochepa panthawi yogwiritsidwa ntchito kwa nthawi yayitali, zomwe zimayambitsa phokoso losazolowereka komanso kutsekeka kwa chivindikiro cha katundu chikatsegulidwa ndi kutsekedwa, komanso zimapangitsa kuti zikhale zosatheka kutsegula kapena kutseka bwino. Pankhaniyi, tikukulimbikitsani kusintha ma hinge onse a fakitale yoyambirira. Mukayika, samalani ndi kusunga ngodya yopingasa kuti muwonetsetse kuti ma hinge atsopano akugwira ntchito bwino komanso nthawi yayitali.
Kuletsa kuyenda mopitirira muyeso
Mu mapangidwe ena ovuta a hinge mechanism, kutsekereza kwambiri kungachitike, zomwe zingakhudze kuyenda kwabwinobwino kwa hinges. Mwachitsanzo, mu mitundu ina ya multi-link hinges, ma rotational joints ambiri angayambitse kusokonekera kwa dongosolo, zomwe zimapangitsa kuti pakhale kutsekereza kwambiri. Yankho la kutsekereza kwambiri ndikusinthira ma rotational joints ena ndi ma point-line joints, ndikutulutsa ma point-line degrees of freedom, kuti ma hinges athe kuyenda bwino.
Kusamalira ndi kusamalira ma hinges a zipinda zonyamula katundu zamagalimoto
Kuti muwonjezere nthawi yogwira ntchito ya ma hinge a chipinda chonyamulira katundu ndikuchepetsa kusokonekera kwa zinthu, kukonza ndi kusamalira tsiku ndi tsiku ndikofunikira kwambiri. Choyamba, yang'anani nthawi zonse ngati mabatani olumikizira ma hinge ali omasuka. Ngati ndi choncho, amangeni nthawi yake. Kachiwiri, sungani ma hinge oyera kuti dothi, mchenga, ndi fumbi zisalowe m'ma hinge ndikusokoneza magwiridwe antchito awo. Kachitatu, ikani mafuta odzola nthawi zonse kuti muchepetse kuwonongeka kwa ma hinge ndikuwongolera kusalala kwawo. Mukamagwiritsa ntchito chipinda chonyamulira katundu, pewani kutsegula ndi kutseka mwamphamvu, ndipo yesani kutsegula ndi kutseka pang'onopang'ono kuti muchepetse kuwonongeka ndi kuwonongeka kwa ma hinge.
Pomaliza, ngakhale kuti ma hinge a chipinda chonyamulira katundu ndi ang'onoang'ono, amachita gawo lofunika kwambiri pakugwiritsa ntchito galimoto. Kumvetsetsa ntchito zawo, zolakwika zomwe zimachitika kawirikawiri, ndi mayankho ake, komanso kukonza ndi kusamalira tsiku ndi tsiku kungatsimikizire kuti ma hinge a chipinda chonyamulira katundu amakhalabe bwino nthawi zonse, zomwe zimapangitsa kuti maulendo athu akhale osavuta komanso otetezeka.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
