M'magalimoto amakono, njira yothandizira imaperekedwa yomwe imapereka kuyenda momasuka panthawi yamvula - chopukuta.Dongosolo ili limayendetsedwa ndi injini yamagetsi.Werengani zonse za gawoli, mawonekedwe ake, kusankha, kukonza ndikusintha m'nkhaniyi.
Cholinga ndi ntchito za wiper gear motor
Wiper geared motor ndi mota yamagetsi yamphamvu yotsika yophatikizidwa ndi gearbox yomwe imagwira ntchito ngati ma wiper agalimoto.
Magalimoto ayenera kuyendetsedwa mu nyengo zonse, kuphatikizapo mvula yamitundu yonse - mvula ndi matalala.Komanso, ntchito ya galimoto, thirakitala, basi kapena zipangizo zina siziyenera kukhudzidwa ndi kulowetsa madzi ndi dothi pawindo lakutsogolo.Zonsezi zimaperekedwa ndi dongosolo lothandizira lomwe limayikidwa kutsogolo ndi / kapena zenera lakumbuyo - ma wipers a windshield.Kuyeretsa mwachindunji galasi kumachitidwa ndi maburashi apadera osunthika, oyendetsa omwe amaperekedwa ndi chipangizo chopangidwa ndi electromechanical unit - motor geared.
Wiper gear motor ili ndi ntchito zazikulu zitatu:
● Wiper blade drive;
● Kuonetsetsa kusuntha kobwerezabwereza kwa ma wiper blade;
● Imitsani maburashi mumodzi mwa malo ovuta kwambiri pamene chopukuta chazimitsidwa.
Mkhalidwe ndi magwiridwe antchito agalimoto yoyendetsedwa zimadalira osati pakugwira ntchito kwa wiper, komanso kulimba mtima komanso kotetezeka kwagalimoto.Chifukwa chake, gawo lolakwika liyenera kukonzedwa kapena kusinthidwa.Koma musanapite ku sitolo kwa injini yatsopano yokonzekera, muyenera kumvetsetsa mapangidwe, ntchito ndi mawonekedwe a zigawo zamagalimoto.
Kupanga, magwiridwe antchito ndi mawonekedwe a wiper geared motors
Pamagalimoto ambiri amakono, ma motors amagetsi amtundu wa nyongolotsi amagwiritsidwa ntchito.Mapangidwe a unit wotere nthawi zambiri amakhala osavuta, amakhala ndi magawo awiri:
● Moto wamagetsi otsika mphamvu;
● Bokosi la gear loikidwa m'nyumba yokhazikika pambali ya shaft yake.
Galimoto yamagetsi nthawi zambiri imakhala yozungulira, yolunjika, yopangira magetsi a 12 kapena 24 V. Kuteteza mbali zamkati za injini kuzinthu zoyipa zachilengedwe (madzi, fumbi, zonyansa zosiyanasiyana), mlandu wosindikizidwa kapena chivundikiro chowonjezera choteteza. amagwiritsidwa ntchito.Mapangidwe awa amakupatsani mwayi woyika injini ya wiper m'malo agalimoto omwe ali ndi chitetezo chochepa.
Bokosi la gear ndi lamtundu wa mphutsi, zomwe zimapereka kusintha kwa liwiro la shaft yotulutsa nthawi imodzi ndi kuzungulira kwa 90-degree kwa torque.Mwadongosolo, ma gearbox ali amitundu iwiri:
● Ndi kuyendetsa mwachindunji kwa zida zoyendetsedwa kuchokera ku nyongolotsi;
● Ndi magiya oyendetsedwa ndi magiya apakati (apakatikati) ang'onoang'ono.
Kapangidwe kake ka injini ya wiper gear
Munthawi yoyamba, bokosi la gear lili ndi magawo awiri okha: nyongolotsi yolumikizidwa ndi shaft yamagalimoto ndi zida zoyendetsedwa ndi mano opindika.Mu gawo lachiwiri, gearbox imakhala ndi magawo atatu kapena anayi: nyongolotsi yolumikizidwa ndi zida zapakatikati (kapena magiya awiri) ang'onoang'ono, ndi zida zoyendetsedwa.Mphutsi nthawi zambiri imakhala yachitsulo, yodutsa imodzi, nthawi zambiri imadulidwa mwachindunji pamtengo wamagetsi amagetsi.Mbali yakutsogolo ya nyongolotsi (kapena shaft yomwe nyongolotsi imadulidwa) ili mu manja (chitsulo, ceramic) kapena kunyamula, ndikubwezera mphamvu za axial zomwe zimachokera ku nyongolotsi, mbali yakumbuyo ya shaft ya injini imakhala. pa nsonga yopondereza yomwe ili kumapeto kwa nyumbayo.
Zida zoyendetsedwa ndi bokosi la gear zimayikidwa pamtengo wachitsulo womwe umapitilira kupitilira nyumba ya gearbox, chiboliboli chimayikidwa pagawo lake lotuluka, lomwe, lomwe limalumikizidwa ndi wiper trapezoid (kulumikiza ndodo ndi ndodo).Crank, pamodzi ndi trapezoid, imatembenuza kusuntha kwa giya kukhala njira yobwerezabwereza ya ma wiper.
Bokosi la gear limayikidwa m'nyumba yosindikizidwa yokhazikika panyumba yamoto kuchokera kumbali ya shaft yake.Nyumba ya gearbox imakhalanso ndi zinthu zowongolera wiper:
- Limit switch - zolumikizirana zozimitsa injini yolumikizidwa mu imodzi mwamalo owopsa a maburashi;
- Fuse ya Thermobimetallic yozimitsa injini ikatenthedwa ngati ikuphwanyidwa kapena kudzaza.
Kusintha kwa malire a mota yamagetsi kumatsimikizira kuti maburashi ayima pamalo amodzi kwambiri - m'munsi kapena kumtunda, kutengera mtundu wa wiper ndi mawonekedwe agalimoto yagalimoto.Kulumikizana kumeneku kumatsegulidwa ndi kamera yapadera pa gear, ndipo kutsekedwa kosalekeza kumaperekedwa ndi kasupe.Ntchito yosinthira malire ikufotokozedwa pansipa.
Fuse ya thermobimetallic imatha kugwiritsidwanso ntchito, imaphatikizidwa pakupuma mu imodzi mwa mawaya amagetsi amagetsi olumikizidwa ndi kulumikizana kwa chosinthira malire.Fuseyi imawonetsetsa kuti gawo lamagetsi lamagetsi lamagetsi limatsegulidwa ikatsekedwa kapena kulemedwa chifukwa cha kupanikizana kwa zida.
Zokwera zokwera (nthawi zambiri zidutswa zitatu) nthawi zambiri zimapangidwa panyumba ya gearbox, mothandizidwa ndi gawo lonse lomwe limayikidwa mwachindunji pagawo la thupi kapena pabulaketi yachitsulo (yomwe, nayonso, imatha kukhalanso ngati maziko oyikapo. chotsitsa cha trapezoid).Mabowo okwera amapangidwa mu bulaketi, momwe mphira kapena pulasitiki matabwa amayikidwa, kupereka kuyika kolimba kwa unit, komanso daping shocks ndi vibrations.Galimoto yowongolera ya chopukutira chakutsogolo imayikidwa pansi kapena pamwamba pa chowongolera chakutsogolo mu niches yoyenera (mwachitsanzo, mu mpweya wotenthetsera chotenthetsera), chopukutira chakumbuyo chimayikidwa pansi pa chitseko chakumbuyo kapena chakumbuyo.Kuti mulumikizane node kumagetsi amagetsi agalimoto, cholumikizira chokhazikika chimaperekedwa pazingwe zama waya kapena pathupi.

The geared motor ntchito motere.Pamene chopukutira anayatsidwa, panopa amalowa injini kudzera malire lophimba ndi fuseji bimetallic, kutsinde ake akuyamba azungulire, ndi mphutsi gearbox, pamodzi ndi crank ndi trapezoid, amapereka kubwerezabwereza maburashi.Pamene chofufutira chazimitsidwa, injini mphamvu dera si kutsegula yomweyo, koma pa nthawi yomweyo cam'onoting'ono kufika giya wa kulankhula malire lophimba - mu nkhani iyi, maburashi kusiya mu kwambiri udindo ndipo musapitirire patsogolo.Zomwezo zimachitikanso pamene chofufutiracho chimasamutsidwa ku ntchito yapakatikati, koma pakapuma pang'ono (imayikidwa ndi chowombera chowombera), magetsi amaperekedwa kwa galimoto yodutsa malire, maburashi amapanga ma oscillation angapo, ndikuyimitsa kachiwiri. malo kwambiri, ndiye kuzungulira kubwereza.
Ma motors ambiri opukutira ali ndi ma gearbox omwe ali ndi chiŵerengero cha 50: 1, chomwe chimaonetsetsa kuti masambawo akuyenda mozungulira 5-60 (kugwedezeka mbali zonse ziwiri) pamphindi m'njira zosiyanasiyana (nthawi zonse komanso mosalekeza).
Momwe mungasankhire bwino, kukonza ndikusintha makina a wiper gear
Ngati galimoto yoyendetsedwa ikulephera, ntchito ya wiper imasokonekera mpaka galasi silingathe kutsukidwa kwathunthu.Zowonongeka zimatha kuwonetseredwa ndi phokoso lamitundu yosiyanasiyana ndi ma squeaks kuchokera ku gearbox.Kuti mudziwe mtundu wa kuwonongeka, m'pofunika kuyang'ana msonkhano, ndiyeno mukonze kapena m'malo mwa msonkhano.Nthawi zambiri, mavuto amawuka mu gearbox - kuvala kwa zida kumachitika ndikuwonongeka kwa tchire / mayendedwe / mayendedwe oponderezedwa, nthawi zambiri zovuta zimawonedwa mu mota yamagetsi.Mutha kuyesa kubwezeretsa bokosi la gear, koma ndi kuvala yunifolomu ya magiya, ndikosavuta kusinthira msonkhano.
Ndi injini ya gearbox yokhayo yomwe idayikidwa pagalimoto ndi wopanga ndiyomwe iyenera kusinthidwa.Ngati izi sizingatheke pazifukwa zilizonse, ndiye kuti mukhoza kuyesa kukhazikitsa unit yamtundu wina kapena chitsanzo, koma nthawi zambiri pamakhala zovuta pakuyika (popeza mabowo okwera ndi miyeso ya ziwalozo sizikugwirizana) ndi mukusintha kotsatira.Ndikofunikira kugwira ntchito motsatira malangizo a kukonza galimotoyo.
Ndi kusankha kolondola ndikusintha kwa injini ya geared, wiper imayamba kugwira ntchito popanda kusintha kwina, kupereka kuyendetsa bwino nyengo iliyonse.
