M'galimoto iliyonse yamakono pali chopukuta, momwe kuyendetsa kwa maburashi kumayendetsedwa ndi njira yosavuta - trapezoid.Werengani zonse za wiper trapezoids, mitundu yawo yomwe ilipo, mapangidwe ndi mfundo zogwirira ntchito, komanso kusankha kolondola ndikusintha zigawozi m'nkhaniyi.
Kodi wiper trapezoid ndi chiyani?
Wiper trapezoid ndi wiper drive, dongosolo la ndodo ndi levers zomwe zimapereka mayendedwe obwerezabwereza a wiper blades pa windshield kapena galasi lakumbuyo la magalimoto.
Pa magalimoto, mabasi, mathirakitala ndi zipangizo zina, nthawi zonse pamakhala chopukutira - njira yothandizira yomwe imatsuka galasi lamoto kumadzi ndi dothi.Machitidwe amakono amayendetsedwa ndi magetsi, ndipo kusamutsidwa kwa mphamvu kuchokera ku galimoto yamagetsi kupita ku maburashi kumachitika pogwiritsa ntchito ndondomeko ya ndodo ndi zitsulo zomwe zimayikidwa pansi pa galasi - wiper trapezoid.
Wiper trapezoid ili ndi ntchito zingapo:
● Yendetsani ma wiper blade kuchokera pa mota yamagetsi;
● Kupanga maburashi obwerezabwereza (kapena maburashi) ndi matalikidwe ofunikira;
● Mu ma wipers a masamba awiri ndi atatu, amaonetsetsa kuti masambawo aziyenda motsatira njira zomwezo kapena zosiyana pa tsamba lililonse.
Ndi wiper trapezoid yomwe imatsimikizira kusuntha kwa "wipers" pagalasi ndi matalikidwe ofunikira (kukula) ndi synchrony, ndipo kuwonongeka kwa gawoli pang'onopang'ono kapena kumasokoneza ntchito ya dongosolo lonse.Pazowonongeka, trapezoid iyenera kukonzedwa kapena kusinthidwa pamsonkhano, koma musanayambe kukonza, muyenera kumvetsetsa mitundu yomwe ilipo ya njirazi, mapangidwe awo ndi mfundo zogwirira ntchito.
Magalimoto onse, mathirakitala ndi makina osiyanasiyana ali ndi zowongolera zowongolera.Kuwonongeka kwa chipangizochi kumasokoneza kayendetsedwe ka magetsi onse, nthawi zina izi zingayambitse kuwonongeka kwa zipangizo zamagetsi ndi moto.Choncho, wolamulira wolakwika ayenera kusinthidwa mwamsanga, ndipo kuti asankhe bwino gawo latsopano, m'pofunika kumvetsetsa mitundu yomwe ilipo, mapangidwe ndi mfundo zoyendetsera olamulira.
Mitundu, kapangidwe ndi mfundo yogwiritsira ntchito wiper trapezoid
Choyamba, trapezoids onse akhoza kugawidwa mu mitundu itatu malinga ndi chiwerengero cha maburashi:
● Kwa ma wipers a windshield a bulashi imodzi;
● Zopukuta zamitundu iwiri;
● Zopukuta zamitundu itatu.
Chithunzi cha chofufutira cha burashi imodzi
Chithunzi cha chofufutira chamitundu iwiri
Panthawi imodzimodziyo, kuyendetsa kwa burashi imodzi sikungatchedwe kuti trapezoid, chifukwa nthawi zambiri imamangidwa pa galimoto yamagetsi yokhala ndi gearbox popanda ndodo zowonjezera kapena ndodo imodzi.Ndipo ma trapezoid awiri ndi atatu ali ndi chipangizo chofanana ndipo amasiyana kokha ndi ndodo.
Komanso, trapezoids awiri ndi atatu burashi akhoza kugawidwa mu mitundu iwiri malinga ndi malo kumene galimoto magetsi chilumikizidwe:
● Symmetrical - galimoto yamagetsi imakhala pakatikati pa trapezoid (pakati pa maburashi), kuonetsetsa kuyenda kwa ndodo zonse ziwiri nthawi imodzi;
● Asymmetric (asymmetrical) - galimoto yamagetsi imayikidwa kumbuyo kwa trapezoid, yomwe imayendetsa galimoto yake ndi zina zowonjezera.
Symmetrical wiper trapezoid
Asymmetrical wiper trapezoid
Masiku ano, ma trapezoid asymmetric ndiofala kwambiri, ali ndi chipangizo chosavuta.Kawirikawiri, maziko a mapangidwewo amapangidwa ndi ndodo ziwiri zokhotakhota, mu hinge pakati pa ndodo ndipo kumapeto kwa imodzi mwa izo pali leashes - zitsulo zazitali zazing'ono, zogwirizana kwambiri ndi odzigudubuza a levers.Komanso, chingwe chapakati chikhoza kukhazikitsidwa mwachindunji mu hinge cholumikizira cha ndodo ziwiri (panthawiyi, ndodo ziwiri ndi leash zimatuluka pamalo amodzi), kapena kulumikiza ndodozo ndi mahinji awiri, ndikunyamula chogudubuza pakati.Pazochitika zonsezi, ma leashes ndi perpendicular kwa ndodo, zomwe zimatsimikizira kupotoza kwawo panthawi yobwereza kayendedwe ka ndodo.
Odzigudubuza amapangidwa ngati ndodo zazifupi zachitsulo, pamwamba pake zomwe ulusi umadulidwa kapena mipata imaperekedwa kuti ikhale yolimba yazitsulo za wiper blade.Nthawi zambiri, odzigudubuza amakhala mu mayendedwe omveka, omwe, nawonso, amagwiridwa ndi mabatani okhala ndi mabowo a fasteners.Ndi mapeto aulere a kukakamiza kwachiwiri, trapezoid imamangiriridwa ku gearbox ya galimoto yamagetsi, yomwe ili ndi mapangidwe ophweka - mu mawonekedwe a crank yomwe ili pamtunda wa motor shaft, kapena wokwera pa gear yochepetsera nyongolotsi. .Galimoto yamagetsi ndi bokosi la gear zimasonkhanitsidwa kukhala gawo limodzi, momwe chosinthira malire chimathanso kupezeka, chomwe chimatsimikizira kuti maburashi ayima pamalo ena pomwe chofufutira chazimitsidwa.
Ndodo, ma leashes, odzigudubuza ndi mabatani a makinawo amapangidwa ndi kupondaponda kuchokera kuchitsulo chachitsulo kapena kupindika zokhala ndi tubular, zomwe zimakhala zolimba kwambiri.Hinges amapangidwa pamaziko a rivets kapena zisoti, matabwa apulasitiki ndi zipewa zoteteza zimayikidwa m'malo olumikizirana ma hinge, mafuta owonjezera angaperekedwenso.Mabowo a hinge mu leashes nthawi zambiri amakhala ozungulira kuti awonetsetse njira yofunikira ya maburashi.
Wiper drive imagwira ntchito motere.Chopukutacho chikayatsidwa, crankyo imatembenuza kusuntha kwa shaft ya motor kuti ikhale yobwerezabwereza ya ndodo za trapezoid, zimachoka pamalo awo apakati kupita kumanja ndi kumanzere, ndipo kudzera m'mitsempha amakakamiza odzigudubuza kuti azungulire panjira inayake. ngodya - zonsezi zimabweretsa kugwedezeka kwa ma levers ndi maburashi omwe ali pamenepo.
Momwemonso, ma trapezoid a ma wipers atatu-burashi amakonzedwa, amangowonjezera ndodo yachitatu ndi leash, kugwira ntchito kwa dongosolo loterolo sikusiyana ndi zomwe zangofotokozedwa kumene.
Symmetrical trapezoids ndi dongosolo la ndodo ziwiri ndi leashes, koma ma leashes ali pa malekezero osiyana a ndodo, ndi zina leash kapena lever anaika mu hinge pakati ndodo kulumikiza ku gearbox ya galimoto yamagetsi.Kuti muwonjezere kukhazikika komanso kuti muchepetse kuyika, bulaketi imatha kuyikidwa mu trapezoid - chitoliro cholumikizira ma leashes a burashi, pakatikati pomwe pangakhale nsanja yoyikamo injini yamagetsi ndi gearbox.Dongosolo loterolo silifuna kukhazikika kosiyana kwa ma leashes kapena odzigudubuza, zomwe zimawonjezera kusavuta komanso kudalirika kwake poyerekeza ndi mitundu ina ya trapezoid.
Wiper trapezoids akhoza kukhala pansi kapena pamwamba pa windshield mu kagawo kakang'ono (chipinda) chopangidwa ndi ziwalo za thupi.Maburaketi okhala ndi ma lever a maburashi amayikidwa pathupi (flush) pogwiritsa ntchito zomangira ziwiri kapena zitatu (kapena mabawuti), ndipo zowongolera zodzigudubuza nthawi zambiri zimasindikizidwa ndi mphete za mphira kapena zipewa zoteteza / zophimba.Galimoto yamagetsi yokhala ndi gearbox imayikidwa mwachindunji pagawo la thupi kapena pabulaketi yomwe imabwera ndi trapezoid.Momwemonso, ma wipers a windshield a single-brush a galasi lakumbuyo amayikidwa.
Momwe mungasankhire ndikusintha wiper trapezoid
Pa ntchito yopukuta, mbali za trapezoid zake zimatha, zimapunduka kapena kugwa - chifukwa chake, makina onse amasiya kugwira ntchito zake moyenera.Kusokonekera kwa trapezoid kumawonetsedwa ndi kusuntha kovuta kwa maburashi, kuyimitsa kwawo nthawi ndi nthawi komanso kusayenda bwino, ndipo zonsezi zitha kutsagana ndi phokoso lochulukirapo.Kuti muzindikire vutolo, ndikofunikira kuyang'ana trapezoid, ndipo ngati kuwonongeka sikungathetsedwe, m'malo mwa makinawo.
Trapezoid atatu-tsamba chopukuta
Ma trapezoid okhawo omwe amapangidwira mwachindunji galimotoyi ayenera kutengedwa kuti alowe m'malo - iyi ndiyo njira yokhayo yowonetsetsa kuti wiper ikhoza kukhazikitsidwa bwino ndipo idzagwira ntchito modalirika.Nthawi zina, amaloledwa kugwiritsa ntchito analogues, komabe, ngakhale pa magalimoto a chitsanzo chomwecho zaka zosiyanasiyana kupanga, njira zikhoza kusiyana mu kusalaza ndi kamangidwe ka ziwalo payekha (omwe amagwirizana ndi kusintha kwa thupi, galasi malo, etc.).
Kusintha kwa trapezoid kuyenera kuchitidwa motsatira malangizo a kukonza galimoto.Nthawi zambiri, kuti muthane ndi makina onse, ndikwanira kuchotsa zotchingira maburashi, kenako kumasula zomangira za mabatani odzigudubuza kapena mabakiti wamba, ndikuchotsa msonkhano wa trapezoid ndi mota ndi gearbox.M'magalimoto ena, trapezoid ndi injini yamagetsi zimachotsedwa padera, ndipo kupeza zomangira zawo kumachitika kuchokera kumbali zosiyanasiyana za niche pansi pa windshield.Kuyika kwa makina atsopano kumachitika motsatira dongosolo, ndipo pangafunike kudzoza mbali zina.Popanga kukhazikitsa, ndikofunikira kuyang'anira malo olondola a ndodo, leashes ndi mbali zina za trapezoid, apo ayi ntchito ya makinawo ikhoza kusokonezedwa.Ngati trapezoid yasankhidwa ndikuyikidwa bwino, chopukuta chidzagwira ntchito modalirika, kusunga ukhondo ndi kuwonekera kwa galasi muzochitika zonse.
