Mune chero motokari yemazuva ano kune wiper, umo dhiraivha yemabhurashi inoitwa nenzira iri nyore - trapezoid.Verenga zvese nezve wiper trapezoids, marudzi avo aripo, dhizaini uye musimboti wekushanda, pamwe nesarudzo chaiyo uye kutsiva kwezvikamu izvi munyaya ino.
Chii chinonzi wiper trapezoid?
Wiper trapezoid ndeye wiper drive, sisitimu yetsvimbo uye lever inopa kudzokororwa mafambiro eiyo wiper blades pamhepo kana girazi remusuwo remota.
Pamotokari, mabhazi, matirakita uye zvimwe midziyo, pane nguva dzose wiper - yekubatsira sisitimu inochenesa windshield kubva mumvura uye tsvina.Masisitimu emazuva ano anofambiswa nemagetsi, uye kutamiswa kwesimba kubva kumagetsi emagetsi kuenda kumabhurashi kunoitwa uchishandisa hurongwa hwetsvimbo uye levers yakaiswa pasi pegirazi - wiper trapezoid.
Iyo wiper trapezoid ine akati wandei mabasa:
● Tyaira mawiper blades kubva mumotokari yemagetsi;
● Kuumbwa kwekudzoreredza kufamba kwemabhurashi (kana mabhurashi) ane amplitude inodiwa;
● Mumawiper maviri-matatu-ma-blade, inova nechokwadi chekufamba-famba kwema-blades pamwe chete kana nzira dzakasiyana-siyana dzeblade imwe neimwe.
Ndiyo wiper trapezoid iyo inovimbisa kufamba kwe "wipers" pagirazi neinodiwa amplitude (scope) uye synchrony, uye kusashanda kwechikwata ichi zvishoma kana kukanganisa zvachose kushanda kwehurongwa hwose.Nezve kuparara, trapezoid inofanira kugadziriswa kana kuchinjwa musangano, asi usati watanga kugadzirisa, unofanirwa kunzwisisa marudzi aripo ezvirongwa izvi, magadzirirwo avo uye nheyo yekushanda.
Ese mota, matirakita nemichina yakasiyana-siyana ine relay-regulators.Kusashanda kwechikwata ichi kunokanganisa kushanda kwegadziriro yose yemagetsi, pane dzimwe nguva izvi zvinogona kutungamirira kuparara kwemidziyo yemagetsi nemoto.Nokudaro, mutongi asina kunaka anofanira kuchinjwa nokukurumidza sezvinobvira, uye nokuda kwechisarudzo chakanaka chechikamu chitsva, zvakakosha kunzwisisa marudzi aripo, dhizaini uye nheyo yekushanda kwevatongi.
Mhando, dhizaini uye musimboti wekushanda kweiyo wiper trapezoid
Chekutanga pane zvese, ese trapezoid inogona kukamurwa kuva marudzi matatu zvichienderana nenhamba yemabhurashi:
● Kune bhurashi rimwe chete windshield wipers;
● Pama wipers maviri-blade;
● Zvemawipers matatu.

Panguva imwecheteyo, dhiraivha yebhurashi imwe haigone kunzi trapezoid, nekuti kazhinji inovakwa chete pane yemagetsi mota ine gearbox isina mamwe matanda kana netsvimbo imwe.Uye maviri-uye matatu-bhurashi trapezoids ane chinhu chakafanana mudziyo uye anosiyana chete munhamba yetsvimbo.
Nekudaro, maviri- uye matatu-bhurashi trapezoids inogona kukamurwa kuita mhando mbiri zvichienderana nenzvimbo iyo mota yemagetsi yakabatana:
● Symmetrical - motokari yemagetsi inowanikwa pakati pe trapezoid (pakati pemabhurashi), inochengetedza kufamba kwemakumbo maviri ebhurashi kamwechete;
● Asymmetric (asymmetrical) - motokari yemagetsi inoiswa shure kwetrapezoid, ichipa motokari yayo nekuwedzera lateral thrust.

Asymmetrical wiper trapezoid
Nhasi, asymmetric trapezoids inonyanya kuwanda, vane mudziyo wakareruka.Kazhinji, hwaro hwechigadziro hunoumbwa nematanda maviri ane hinged, mune hinge pakati pematanda uye pamagumo eimwe yadzo pane maredhi - marevhisi ehurefu hudiki, akabatana zvakasimba kune rollers yebrashi levers.Uyezve, iyo yepakati leash inogona kuiswa yakananga mukati mehinge joint yematanda maviri (munyaya iyi, tsvimbo mbiri uye tambo dzinobuda pane imwe pfungwa), kana kubatanidza matanda nemahinji maviri, uye kutakura roller pakati pechikamu.Muzviitiko zvose izvi, mashizha ari perpendicular kune tsvimbo, iyo inovimbisa kutsauka kwavo panguva yekudzoka kwekufamba kwematanda.
Iwo ma rollers anogadzirwa nenzira yemapfupi simbi simbi, pamusoro payo iyo tambo dzakachekwa kana slots inopiwa kune yakasimba kuenderana kweiyo wiper blade levers.Kazhinji, ma rollers anowanikwa mumabhengi akajeka, ayo, zvakare, anobatwa nemabheji ane maburi ezvigadziro.Iine magumo emahara ekusundirwa kwechipiri, trapezoid inosungirirwa kune giya bhokisi remagetsi emagetsi, iro rine rakareruka dhizaini - muchimiro che crank yakanangana neiyo mota shaft, kana yakaiswa pagiya rekudzikisa gonye giya. .Iyo mota yemagetsi uye giya bhokisi zvakaunganidzwa kuita imwechete unit, umo inogadziriswa switch inogonawo kuwanikwa, iyo inova nechokwadi chekuti mabhurashi anomira mune imwe nzvimbo kana wiper yakadzimwa.
Tsvimbo, leashes, rollers uye mabhuraketi emuchina anogadzirwa nekutsikirira kubva pashizha simbi kana nekukotama tubular blanks, ane yakakwirira kukotama rigidity.Hinges inogadzirwa pahwaro hwe rivets kana caps, epurasitiki bushings uye ekudzivirira caps akaiswa munzvimbo dzehinge majoini, mamwe lubrication anogona zvakare kupihwa.Makomba ehinge mumaleashes anowanzo kuve oval kuti ave nechokwadi chetrajectory inodiwa yemabhurashi.
Iyo wiper drive inoshanda sezvinotevera.Kana wiper ikabatidzwa, crank inoshandura kutenderera kwemotor shaft kuita kufambisa kunodzokerana kwetrapezoid rods, dzinobva paavhareji yadzo kuenda kurudyi nekuruboshwe, uye kuburikidza nemaleashes anomanikidza ma roller kutenderera pane imwe nzvimbo. angle - izvi zvese zvinotungamira kune hunhu kudengenyeka kweiyo levers uye mabhurashi ari paari.
Saizvozvowo, trapezoids ye-3-brush wipers yakarongedzwa, inongowedzera tsvimbo yechitatu ine leash, kushanda kwegadziriro yakadaro hakuna kusiyana neiyo ichangobva kutsanangurwa.
Symmetrical trapezoids zvakare sisitimu yetsvimbo mbiri dzakadururwa uye tambo, asi machira anowanikwa kune akatarisana migumo yetsvimbo, uye yekuwedzera leash kana lever inoiswa muhinge pakati pematanda kuti abatanidze kune giya bhokisi remagetsi mota.Kuti uwedzere kuomarara uye kurerutsa kuisirwa, bracket inogona kuiswa mune yakadaro trapezoid - pombi inobatanidza mabhurashi leashes, nechepakati chikamu panogona kuve nepuratifomu yekumisikidza mota yemagetsi ine gearbox.Sistimu yakadaro haidi kusungirirwa kwakasiyana kweashes kana rollers, izvo zvinowedzera kuve nyore uye kuvimbika kana zvichienzaniswa nemamwe marudzi e trapezoid.
Wiper trapezoids inogona kuwanikwa pasi kana pamusoro pemhepo yemhepo mune yakakosha niche (compartment) inoumbwa nenhengo dzemuviri.Mabhureki ane bhurashi lever rollers akaiswa pamuviri (flush) nenzira mbiri kana matatu screws (kana mabhaudhi), uye roller inotungamira inowanzovharwa nerubha mhete kana ekudzivirira caps / mavhavha.Iyo mota yemagetsi ine giya bhokisi inoiswa yakananga pachikamu chemuviri kana pabhuraketi rinouya ne trapezoid.Saizvozvo, single-brush windshield wipers yegirazi remusuwo akaiswa.
Nzira yekusarudza uye kutsiva wiper trapezoid
Panguva yekushanda kwewiper, zvikamu zvetrapezoid zvayo zvinopera, zvinokanganisa kana kuparara - semugumisiro, iyo yose nzira inorega kuita mabasa ayo kazhinji.Kusashanda zvakanaka kwetrapezoid kunoratidzwa nekufamba kwakaoma kwemabhurashi, nguva yavo inomira uye desynchronization yekufamba, uye izvi zvese zvinogona kuperekedzwa neruzha rwakawedzerwa.Kuti uone kusashanda, zvakakosha kutarisa trapezoid, uye kana kuparara kusingagoni kubviswa, shandura nzira.
Trapezoid matatu-blade wiper
Izvo chete trapezoid dzakagadzirirwa zvakanangana nemotokari iyi dzinofanira kutorwa kuti dzitsive - iyi ndiyo nzira chete yekuvimbisa kuti wiper inogona kuiswa zvakajairika uye ichashanda yakavimbika.Mune zvimwe zviitiko, zvinotenderwa kushandisa analogues, zvisinei, kunyange pamotokari dzemhando imwechete yemakore akasiyana ekugadzirwa, nzira dzinogona kusiyana mukutsanya uye kugadzira kwezvikamu zvega (izvo zvinosanganiswa nekuchinja kwechimiro chemuviri. girazi nzvimbo, nezvimwewo).
Kutsiviwa kwetrapezoid kunofanira kuitwa maererano nemirairo yekugadzirisa motokari.Kazhinji, kuti ubvise dhizaini yese, zvinokwana kubvisa mabhurashi, wobva wasunungura zvisungo zvemabhureki e roller kana iyo yakajairika bracket, uye bvisa iyo trapezoid musangano nemota uye gearbox.Mune dzimwe motokari, trapezoid uye motokari yemagetsi inobviswa zvakasiyana, uye kupinda kune zvigadziro zvavo kunoitwa kubva kumativi akasiyana e niche pasi pemhepo.Kuiswa kwemuchina mutsva kunoitwa munhevedzano kurongeka, uye zvingave zvakakosha kuisa mamwe mativi.Paunenge uchiita kuiswa, zvakakosha kutarisa nzvimbo yakarurama yetsvimbo, leashes uye zvimwe zvikamu zve trapezoid, kana zvisina kudaro kushanda kwemaitiro kunogona kuvhiringidzwa.Kana iyo trapezoid yakasarudzwa uye yakaiswa zvakanaka, wiper ichashanda yakavimbika, kuchengetedza utsanana uye pachena kwegirazi mumamiriro ese ezvinhu.
