Mumotokari dzemazuva ano, hurongwa hwekubatsira hunopiwa hunopa kufamba kwakasununguka panguva yekunaya - wiper.Iyi sisitimu inofambiswa neyakagadzirirwa mota.Verenga zvese nezve iyi unit, magadzirirwo ayo, sarudzo, kugadzirisa uye kutsiva mune chinyorwa.
Chinangwa uye mabasa eiyo wiper giya mota
Wiper geared mota imotokari yemagetsi yakaderera-yakasanganiswa negiya bhokisi rinoita sedhiraivha yekupukuta mota.
Mota dzinofanirwa kushandiswa mumamiriro ekunze ese, kusanganisira panguva yekunaya kwemhando dzese - mvura nechando.Zvakare, kushanda kwemotokari, tarakita, bhazi kana chero imwe midziyo haifanirwe kukanganiswa nekupinda kwemvura uye tsvina pamhepo.Zvese izvi zvinopihwa neanobatsira sisitimu yakamisikidzwa kumberi uye / kana kumashure kwehwindo - windshield wipers.Kuchenesa zvakananga girazi kunoitwa nemabhurashi akakosha anofambiswa, dhiraivha iyo inopihwa neyakavakirwa-mukati electromechanical unit - geared motor.
Iyo wiper giya mota ine matatu makuru mabasa:
● Wiper blade drive;
● Kuve nechokwadi chekufamba kunodzokorora kwema-wiper blades;
● Misa mabhurashi mune imwe yenzvimbo dzakanyanyisa apo wiper inodzimwa.
Mamiriro uye kushanda kweiyo geared mota kunoenderana kwete chete nekushanda kweiyo wiper, asi pane ine chivimbo uye yakachengeteka kushanda kwemotokari.Nokudaro, chikwata chinokanganisa chinofanira kugadziriswa kana kuchinjwa.Asi usati waenda kuchitoro kune mota nyowani, unofanirwa kunzwisisa dhizaini, mashandisiro uye maficha eizvi zvemotokari zvikamu.
Dhizaini, mashandiro uye maficha eiyo wiper geared motors
Pamotokari zhinji dzemazuvano, honye-mhando yemagetsi geared motors anoshandiswa.Dhizaini yeyuniti yakadaro kazhinji iri nyore, ine zvikamu zviviri zvikuru:
● Low-power drive motor;
● Giya bhokisi rakaiswa mudzimba rakasungirirwa pamotokari padivi peshaft yaro.
Iyo mota yemagetsi inowanzo commutator, yakananga ikozvino, yekugovera voltage ye12 kana 24 V. Kuchengetedza zvikamu zvemukati zveinjini kubva kune zvakaipa zvinokanganisa zvakatipoteredza (mvura, guruva, zvakasvibiswa zvakasiyana), kesi yakavharwa kana chivharo chekuwedzera chekudzivirira. inoshandiswa.Iyi dhizaini inobvumidza iwe kuti uise iyo wiper giya mota munzvimbo dzemuviri wemotokari dzine dziviriro shoma.
Iyo gearbox ndeyemhando yehonye, iyo inopa shanduko mukumhanya kweiyo shaft yekubuda panguva imwe chete ne90-degree kutenderera kwekuyerera kwe torque.Zvimiro, magiya mabhokisi ndeemhando mbiri:
● Nekutyaira kwakananga kwegiya rinofambiswa kubva kune honye;
● Nekufambiswa kwegiya dhiraivha kuburikidza nepakati (yepakati) magiya ediki dhayamita.
Iyo yakajairika chimiro cheiyo wiper giya mota
Muchiitiko chekutanga, giya bhokisi rine zvikamu zviviri chete: gonye rakabatana nemota shaft uye giya rinotyairwa rine mazino econcave.Muchiitiko chechipiri, bhokisi regiya rine zvikamu zvitatu kana zvina: gonye rakabatana negiya repakati (kana maviri magiya) ediki dhayamita, uye giya rinotyairwa.Gonye rinowanzoita simbi, imwe-pass, kazhinji inochekwa yakananga pashaft yemagetsi mota.Iyo yepamberi chikamu chehonye (kana shaft yakachekwa honye) iri mune sleeve (simbi, ceramic) kana kutakura, uye kutsiva iyo axial mauto anobva muhonye, chikamu chekumashure cheinjini shaft inozorora. pa thrust bearing iri kumucheto kumashure kweimba.
Iyo inotyairwa giya regiya bhokisi rakaiswa pane simbi shaft inosvika mhiri kwegiya bhokisi redzimba, crank inoiswa pane yayo inobudikira chikamu, icho, ichowo, chakabatana kune wiper trapezoid (yekubatanidza tsvimbo rack netsvimbo).Iyo crank, pamwe chete ne trapezoid, inoshandura kutenderera kutenderera kwegiya kuita kudzoreredza mafambiro eiyo wiper blades.
Iyo gearbox inoiswa mune yakavharwa imba yakasungirirwa pane mota dzimba kubva padivi peshaft yayo.Iyo giya bhokisi dzimba zvakare inogara zvinhu zve otomatiki wiper control:
- Limit switch - mabatiro ekudzima mota yakasungirirwa mune imwe yenzvimbo dzakanyanyisa dzemabhurashi;
- Thermobimetallic fuse yekudzima injini kana ichipisa kana paine jamming kana kuwandisa.
Iyo yekumisikidza switch yemota yemagetsi inovimbisa kuti mabhurashi anomira mune imwe yenzvimbo dzakanyanyisa - muzasi kana kumusoro, zvichienderana nerudzi rwe wiper uye magadzirirwo emota cab.Aya maitirwo anovhurwa nekamera yakakosha pagiya, uye kuvhara nguva dzose kunopiwa nechitubu.Kushanda kwemuganhu wekuchinja kunotsanangurwa pasi apa.
Iyo thermobimetallic fuse inogona kushandiswa zvakare, inosanganisirwa mukuputsika mune imwe yemagetsi tambo dzemagetsi mota yakabatana nekusangana kweiyo muganhu switch.Iyo fuse inovimbisa kuti magetsi emagetsi emagetsi anovhurwa kana yakavharwa kana kuremerwa nekuda kwekujairika kwearature.
Kukwirisa racks (kazhinji zvidimbu zvitatu) zvinowanzo gadzirwa paimba yegiya bhokisi, nerubatsiro rwekuti iyo unit yese inomisikidzwa yakananga pachikamu chemuviri kana pane simbi bracket (iyo, zvakare, inogona kuita sehwaro hwekukwira. iyo wiper trapezoid).Makomba anokwirisa anogadzirwa mubhuraketi, umo mazambuko erabha kana epurasitiki akaiswa, achipa kuisirwa kwakasimba kweiyo unit, pamwe nekudzikisa kuvhunduka uye vibrations.Iyo mota yakagadziridzwa yekumberi wiper yakaiswa pasi kana pamusoro pechivharo chemhepo mune yakakodzera niches (somuenzaniso, mumhepo inotora heater), iyo yekumashure wiper inoiswa pasi peiyo trim yemusuwo wekumashure kana kumashure.Kuti ubatanidze node kune network yemagetsi yemotokari, chiyero chekubatanidza chinopiwa pane wiring harness kana pamuviri.
Windshield
wiper giya mota Shaft parutivi wiper giya mota
Iyo geared mota inoshanda seinotevera.Kana iyo wiper ikavhurwa, yazvino inopinda muinjini kuburikidza nemuganho switch uye bimetallic fuse, shaft yayo inotanga kutenderera, uye worm gearbox, pamwe chete ne crank uye trapezoid, inopa kudzokororwa kwekufamba kwemabhurashi.Kana iyo wiper yakadzimwa, injini yemagetsi dunhu haivhurike pakarepo, asi chete panguva iyo cam inosvika giya remiganho switch contacts - mune iyi kesi, mabhurashi anomira munzvimbo yakanyanyisa uye haafambi mberi.Izvi zvakafanana zvinoitika kana wiper ichiendeswa kukushanda kwepakati, asi mushure meimwe kumbomira (yakagadzikwa neiyo wiper breaker relay), iyo yazvino inopihwa kune mota ichipfuura nekuchinjisa switch, mabhurashi anoita akati wandei oscillations, omira zvakare mukati. nzvimbo yakanyanyisa, ipapo kutenderera kunodzokorora.
Mazhinji wiper geared motors ane magiya mabhokisi ane avhareji yegiya reshiyo ye50: 1, iyo inovimbisa kushanda kwemablades pa frequency ye5-60 kutenderera (kutenderera mumativi ese) paminiti munzira dzakasiyana siyana (nguva dzose uye inopindirana).
Maitiro ekusarudza zvakanaka, kugadzirisa uye kutsiva wiper giya mota
Kana iyo geared motor ikakundikana, kushanda kwewiper kunokanganiswa kusvikira girazi risingagoni kucheneswa zvachose.Kusashanda kunogona kuratidzwa neruzha rwakasiyana uye squeaks kubva mugearbox.Kuti uone rudzi rwekuputsika, zvakakosha kutarisa gungano, uye wozogadzirisa kana kuitsiva mumusangano.Kazhinji kazhinji, matambudziko anomuka mubhokisi regiya - kupfeka kwegiya kunoitika uye kukuvadzwa kwebhushi / mabhengi / kutakura mabhengi, kazhinji kusashanda kunoonekwa mumotokari yemagetsi.Iwe unogona kuedza kudzoreredza giya bhokisi, asi nekupfeka yunifomu yegiya, zviri nyore kutsiva gungano regungano.
Iyo chete gearbox mota yemhando iyo yakaiswa pamota nemugadziri ndiyo inofanirwa kutorwa kuti itsive.Kana izvi zvisingagoneki nekuda kwechikonzero chero chipi zvacho, saka unogona kuedza kuisa yuniti yerudzi rwakasiyana kana modhi, asi kazhinji mune iyi kesi pane zvinonetsa mukuisa (sezvo maburi ekukwira uye zviyero zvezvikamu hazvienderane) uye mukugadzirisa kunotevera.Izvo zvinodikanwa kuita basa zvinoenderana nemirairo yekugadziriswa kwemotokari.
Nekusarudzwa kwakaringana uye kutsiva mota yakarongedzerwa, wiper inotanga kushanda pasina mamwe magadzirirwo, ichipa yakasununguka kutyaira mune chero mamiriro ekunze.
