Maziko Oyambira a Makina Oyimitsa Galimoto Yopepuka kwa Oyamba
Dongosolo loyimitsa magalimoto ndi chimodzi mwa zinthu zofunika kwambiri pa magalimoto opepuka monga magalimoto onyamula anthu, mabasi ang'onoang'ono, kapena magalimoto ang'onoang'ono ogulitsa. Ngakhale kuti nthawi zambiri "siliwoneka" chifukwa cha malo ake pansi pa thupi, kuyimitsa magalimoto kumachita gawo lofunika kwambiri pakukhala bwino, kukhazikika, chitetezo, komanso moyo wa zinthu zina. Kwa oyamba kumene, kumvetsetsa mfundo zoyimitsa magalimoto kudzathandiza kuzindikira zizindikiro za kuwonongeka, kusankha kukonza koyenera, ndikumvetsetsa chifukwa chake galimoto imawoneka yofewa, yolimba, yosakhazikika, kapena yokhazikika ikayendetsa.
1. Kodi Kuyimitsidwa ndi Chiyani Ndipo N’chifukwa Chiyani Kuli Kofunika?
Mwachidule, suspension ndi njira yomwe imalumikiza mawilo ku chimango/thupi la galimoto. Mawilo akamayenda pamwamba pa ma bumps, mabowo, kapena ma speed bumps, suspension imayamwa ma shock kotero kuti satumizidwa mwachindunji ku kabati. Komabe, ntchito yake imapitirira kumasuka. Suspension imasunganso kukhudzana kwa matayala ndi msewu (kusunga msewu), kuonetsetsa kuti mabuleki ndi magwiridwe antchito abwino.
Popanda kuyimitsa bwino galimoto, galimoto imagunda mosavuta, imataya mphamvu ikamayenda, ndipo imafulumizitsa kuwonongeka kwa matayala ndi pansi pa galimoto. Chifukwa chake, kuyimitsa galimotoyo kungaganizidwe ngati kuphatikiza kwa "chotsitsa" ndi "chokhazikika" cha galimoto.
2. Ntchito Yaikulu ya Dongosolo Loyimitsa
Ntchito zazikulu za kuyimitsidwa pamagalimoto opepuka ndi izi:
1. Zimayamwa kugwedezeka ndi kugwedezeka
Mawilo akagundana ndi vuto pamsewu, kuyimitsidwako kumachepetsa mphamvu yamagetsi yomwe imalowa m'thupi.
2. Sungani matayala akuyang'anizana ndi msewu
Tayala likamayenda bwino, limakhala ndi mphamvu yokoka, kutseka bwino komanso kukhazikika bwino.
3. Thandizani katundu wa galimoto
Choyimitsacho chimathandizira kulemera kwa galimoto, okwera ndi katundu, komanso chimasunga kutalika kwa ulendo wa galimotoyo.
4. Kulamulira mayendedwe a thupi
Pa nthawi yothamanga, kutseka, ndi kupotoza, thupi limakonda kuponya, kugubuduza, kapena kuboola. Choyimitsacho chimalamulira mayendedwe awa kuti galimotoyo ikhale yokhazikika.
3. Zigawo Zazikulu Zoyimitsidwa
Kwa oyamba kumene, zida zoyimitsira zitha kugawidwa m'magulu angapo ofunikira:
a) Masika
Masipiringi amathandiza kulemera kwa galimotoyo ndipo amalola mawilo kuyenda mmwamba ndi pansi motsatira mizere ya msewu. Mitundu yodziwika bwino ya masipiringi ndi iyi:
– Kasupe wozungulira (kasupe wozungulira): Amagwiritsidwa ntchito kwambiri m'magalimoto onyamula anthu chifukwa ndi omasuka komanso oyankha.
– Masamba a masamba: Amapezeka kwambiri pamagalimoto ang'onoang'ono amalonda chifukwa ndi olimba mokwanira kupirira katundu ndipo ndi osavuta.
– Chopingasa: Ndodo yomwe imagwira ntchito popotoza kuti igwire katundu, yomwe imagwiritsidwa ntchito m'magalimoto angapo.
b) Choyamwitsa Nkhawa (Choletsa Kugwedezeka)
Ma shock absorbers sathandiza katundu wamkulu, koma amalamulira ma spring rebound. Popanda ma shock absorbers, galimotoyo imagunda mobwerezabwereza ikadutsa ma bumps. Ma shock absorbers amasintha mphamvu ya kinetic kukhala kutentha kudzera mu kuyenda kwa mafuta (kapena mafuta a gasi) mkati mwa chubu.
Mitundu ya zoziziritsa kugwedezeka:
- Mafuta a Hydraulic (mafuta)
– Gasi (mafuta a gasi): Nthawi zambiri zimakhala zokhazikika polimbana ndi zizindikiro za "kutha kwa mantha" mukamagwira ntchito yolemetsa.
c) Chokhazikitsira (Chosapindika)
Chokhazikikachi chimathandiza kuchepetsa kugwedezeka pamene chikukokedwa. Chimalumikiza suspension yakumanzere ndi yakumanja kotero kuti mbali imodzi ikakwera ndi kutsika kwambiri, mbali inayo "imailetsa", ndikusunga mulingo wa thupi.
d) Mkono Wozungulira ndi Cholumikizira (Mkono Wolamulira, Mkono Wotsamira, Cholumikizira)
Dzanja lowongolera ndi maulalo osiyanasiyana ndi maulumikizidwe amakaniki omwe amawongolera kuyenda kwa gudumu poyerekeza ndi thupi. Zigawozi zimatsimikiza mawonekedwe a gudumu ndipo zimakhudza kukhazikika.
e) Mabatani a Mpira ndi Zitsulo
- Ma board amalola kuyenda mozungulira komanso mozungulira pa ma suspension (monga mawilo akutsogolo).
– Ma bushing (labala) amachepetsa kugwedezeka ndikupereka kusinthasintha kwa malo olumikizirana. Ngati ma bushing atha, phokoso la "klunking" nthawi zambiri limamveka ndipo kugwira ntchito kumakhala komasuka.
4. Mitundu Yodziwika ya Kuyimitsidwa Kutsogolo kwa Magalimoto Opepuka
a) MacPherson Strut
Mtundu wotchuka kwambiri m'magalimoto onyamula anthu chifukwa cha kapangidwe kake kakang'ono komanso ndalama zochepa zopangira. Gawo lake lalikulu limaphatikiza choziziritsira ndi strut kukhala unit imodzi. Ngakhale kuti imasunga malo komanso yopepuka, nthawi zina imakhala yosasinthasintha poyerekeza ndi makina ambiri olumikizira kuti igwire bwino ntchito.
b) Chigoba Chaching'ono Chawiri
Imagwiritsa ntchito manja awiri (apamwamba ndi otsika) omwe amapanga mawonekedwe a A. Ubwino wake ndikuwongolera bwino mawonekedwe a mawilo pamene suspension ikugwira ntchito, zomwe zimapangitsa kuti ikhale yokhazikika ikangogundana. Komabe, ndi yovuta kwambiri ndipo imatenga malo ambiri.
5. Mitundu Yodziwika ya Kuyimitsidwa Kumbuyo
a) Torsion Beam (Yosadalira kwambiri)
Yogwiritsidwa ntchito kwambiri m'magalimoto ang'onoang'ono komanso apakatikati, kapangidwe kake ndi kosavuta komanso kosunga malo. Ngakhale kuti si yodziyimira payokha, torsion beam ndi yabwino yogwiritsidwa ntchito tsiku ndi tsiku komanso ndalama zochepa zokonzera.
b) Maulalo ambiri (Odziyimira pawokha)
Gudumu lililonse lakumbuyo limayenda palokha ndi manja angapo olumikizirana. Kuligwira ndi kumasuka nthawi zambiri kumakhala bwino, makamaka pamisewu yosalinganika komanso ikangolowa m'makona, koma kumanga kumakhala kovuta kwambiri ndipo kukonza kungakhale kokwera mtengo.
c) Masamba a Kasupe (Malonda Odziwika Kwambiri)
Ma spring a masamba ndi olimba mokwanira kuti azitha kunyamula katundu ndipo ndi olimba. Vuto lake ndilakuti kuyenda kungakhale kovuta galimoto ikatulutsidwa.
6. Mfundo Zoyambira: Kulimba kwa Masika ndi Kuchepetsa Kugwedezeka
Oyamba kumene nthawi zambiri amaganiza kuti suspension "yofewa" imangokhala ngati ma springs. Ndipotu, chomwe chimatsimikizira mtundu wa suspension ndi kuphatikiza kwa ma springs ndi ma shock absorbers.
– Masipiringi ndi ofewa kwambiri: omasuka, koma thupi limagwedezeka mosavuta likamakhota kapena kutseka.
– Masiponji olimba kwambiri: kugwiritsa ntchito kwake kumakhala kolimba, koma matumphuka amaonekera bwino ndipo kugwedezeka m'misewu yodzaza ndi matumphuka kungachepe.
Pa choyatsira mantha:
– Kuchepa kwa madzi m'galimoto ndi kofooka kwambiri: galimotoyo imagundagunda ndipo siikhazikika.
– Kunyowetsa madzi kumakhala kolimba kwambiri: kumakhala kovuta ndipo kungapangitse mawilo "kulumpha" mwachangu m'misewu yoyipa.
Cholinga chake ndi kukhala ndi mtendere wamumtima: kukhala womasuka koma wokhazikika.
7. Zizindikiro Zosavuta Kuzindikirika za Kuwonongeka kwa Kuyimitsidwa
Zizindikiro zotsatirazi nthawi zambiri zimawonekera m'magalimoto opepuka:
1. Galimoto imagunda kwambiri ikadutsa speed bump → mwina zoziziritsa kukhosi zofooka/zotulutsa madzi.
2. Phokoso la kugogoda/kugogoda pamisewu yowonongeka → matabwa osweka, cholumikizira mpira, cholumikizira chokhazikika, kapena choyimitsa kugunda.
3. Kusagwira bwino matayala → mwina kusintha mawonekedwe a mawilo, kusweka kwa ma bushings, kapena zigawo zoyimitsidwa zopindika.
4. Galimoto imakoka mbali imodzi → ikhoza kukhala chifukwa cha mawilo osakhazikika bwino, kuthamanga kwa matayala osiyanasiyana, kapena zinthu zina zoyimitsira zomwe zimakhala ndi vuto.
5. Chiwongolero chimagwedezeka pa liwiro linalake → chikhoza kukhala chogwirizana ndi kulinganiza, komanso chikhoza kuyatsidwa ndi zinthu zoyimitsidwa zotayirira.
Ngati zizindikirozi zikuwonekera, ndi bwino kuzifufuza ku workshop komwe kuli zida zowunikira ndi kuwongolera.
8. Kukonza Koyambira kwa Oyamba Kuyimitsidwa
Njira zosavuta koma zofunika zosamalira:
- Yang'anani nthawi zonse choziziritsira moto (ngati mafuta akutuluka kapena ayi).
– Sungani mphamvu ya tayala motsatira malangizo a wopanga; mphamvu yolakwika ingapangitse kuti kuyimitsidwa kugwire ntchito molakwika kuposa momwe tayala limafunira.
- Pewani kugunda mabowo mwachangu kwambiri, chifukwa izi zitha kuwononga ma rims, matayala ndi zida zoyimitsira.
- Chitani zinthu zolimbitsa mawilo nthawi zonse, makamaka mukangogunda dzenje lalikulu kapena kusintha zida zoyimitsira.
- Samalani ndi nsapato ya rabara (bushing) ndi mpira; rabara yong'ambika imathandizira kulowa kwa fumbi ndikufulumizitsa kuwonongeka.
9. Mapeto
Kumvetsetsa mfundo zoyambira za makina oimitsa magalimoto opepuka kumathandiza oyamba kumene kuwona galimoto osati ngati injini ndi thupi lokha, komanso ngati makina omwe ayenera kukhala omasuka komanso owongolera. Makina oimitsa magalimoto amagwira ntchito pogwiritsa ntchito ma spring, ma shock absorbers, ma links, ma bushings, ndi ma stabilizers kuti atsimikizire kuti mawilo akupitirirabe, kabati imakhalabe yomasuka, ndipo galimotoyo imakhala yotetezeka poyendetsa.
Mwa kumvetsetsa zigawo zazikulu, mitundu ya kuyimitsidwa, ndi zizindikiro zodziwika bwino za kuwonongeka, mutha kuchitapo kanthu mwachangu pokonza, kupewa kuwonongeka kwina, ndikusunga magwiridwe antchito abwino kwambiri agalimoto kwa nthawi yayitali. Ngati mukufuna kufufuza mozama, mutha kuyamba ndi mitu yapamwamba kwambiri monga mawonekedwe a mawilo (camber, caster, toe), zotsatira za kusintha kwa kuyimitsidwa, ndi kusiyana kwa mawonekedwe a kuyimitsidwa kuti chitonthozo chikhale chosangalatsa poyerekeza ndi magwiridwe antchito.
