Headlamp.
Mwenje wemota dzemotokari dzinowanzo umbwa nezvikamu zvitatu: girobhu remwenje, reflekisi uye girazi rinoenderana (astigmatism mirror).
1. girobhu
Magirobhu anoshandiswa mumagetsi emota incandescent bulbs, halogen tungsten bulbs, mwenje mutsva wekupenya kwearc uye zvichingodaro.
(1) Incandescent girobhu: filament yaro yakagadzirwa netambo yetungsten (tungsten ine nzvimbo yakakwirira yekunyungudika uye chiedza chakasimba). Munguva yekugadzira, kuitira kuti uwedzere hupenyu hwebasa rebhubhu, girobhu rinozadzwa negesi inert (nitrogen uye musanganiswa wayo wemagasi anert). Izvi zvinogona kuderedza kubuda kwetambo ye tungsten, kuwedzera tembiricha yefilament, uye kuwedzera kupenya kwakanaka. Chiedza chinobva mugirobhu reincandescent chine yellowish tinge.
(2) Tungsten halide mwenje: Tungsten halide mwenje girobhu inopinzwa muinert gasi mune imwe halide chinhu (senge iodine, chlorine, fluorine, bromine, nezvimwewo), uchishandisa musimboti we tungsten halide recycling reaction, kureva, the gaseous tungsten inoputika kubva mufilament inopindirana nehalogen kuti ibudise tungsten halide inoputika, iyo inopararira kune nzvimbo yakakwirira yekushisa pedyo nefilament, uye yakasvibiswa nekupisa, kuitira kuti tungsten idzoserwe kune filament. Iyo halogen yakaburitswa inoramba ichipararira uye kutora chikamu mune inotevera kutenderera kuita, saka kutenderera kunoenderera, nekudaro ichidzivirira kubuda kwe tungsten uye kudzima kwegirobhu. Tungsten halogen mwenje girobhu saizi idiki, girobhu regirazi rakagadzirwa negirazi requartz rine tembiricha yakakwira uye simba remuchina, pasi pesimba rimwechete, kupenya kwetungsten halogen mwenje ndeye 1.5 nguva yerambi reincandescent, uye hupenyu huri 2 kusvika 3 nguva refu.
(3) Mwenje mutsva wearc unopenya: Mwenje uyu hauna tambo yechinyakare mugirobhu. Pane kudaro, ma electrode maviri anoiswa mukati mequartz tube. Iyo chubhu inozadzwa nexenon uye trace simbi (kana simbi halides), uye kana paine yakakwana arc voltage pa electrode (5000 ~ 12000V), gasi rinotanga kuita ionize uye kuitisa magetsi. Maatomu egasi ari mukunakidzwa uye anotanga kuburitsa chiedza nekuda kwekuchinja kwesimba remaerekitironi. Mushure me 0.1s, shoma shoma ye mercury vapor inoputika pakati pe electrode, uye simba rekushandisa rinobva raendeswa kune mercury vapor arc discharge, uye rinozoendeswa kune halide arc rambi mushure mokunge tembiricha yakwira. Mushure mekunge chiedza chasvika kune yakajairika tembiricha yekushanda yegirobhu, simba rekuchengetedza arc kubuda rakaderera kwazvo (anenge 35w), saka 40% yesimba remagetsi rinogona kuponeswa.
2. reflector
Basa rereflector nderekuwedzera polymerization yechiedza chinoburitswa negirobhu kuita danda rakasimba kuti riwedzere kureba kwekuvhenekera.
Chimiro chepamusoro chegirazi iparaboloid inotenderera, inowanzo gadzirwa 0.6 ~ 0.8mm simbi yakatetepa sheet sheet stamping kana yakagadzirwa negirazi, plastiki. Mukati memukati wakaputirwa nesirivha, aluminium kana chrome uye wozokwenenzverwa; Iyo filament iri panzvimbo yepakati pegirazi, uye yakawanda yemwaranzi yaro yemwenje inoratidzwa uye inopfurwa kure kure sematanda anoenderana. Chiedza chemwenje chisina girazi chinogona kungovhenekera chinhambwe chingangoita 6m, uye danda rakafanana rinoratidzwa negirazi rinogona kuvhenekera chinhambwe chinodarika 100m. Mushure megirazi, kune chiedza chiduku chechiedza chakapararira, icho chepamusoro hachina maturo zvachose, uye chiedza chemashure uye chepasi chinobatsira kujekesa nzira yemugwagwa uye kuvhara kwe5 kusvika ku10m.
3. lenzi
Pantoscope, inozivikanwawo seastigmatic girazi, musanganiswa wemaprism akakosha nemalenzi, uye chimiro chinowanzo tenderera uye rectangular. Basa regirazi rinoenderana nderokudzosa danda rakafanana rinoratidzwa negirazi, kuitira kuti mugwagwa uri pamberi pemotokari uve nemwenje wakanaka uye wakafanana.
sort
Iyo headlamp optical system musanganiswa wegirobhu remwenje, reflector uye girazi rinoenderana. Zvinoenderana neyakasiyana dhizaini yeiyo headlamp optical system, iyo headlamp inogona kukamurwa kuita marudzi matatu: semi-yakavharwa, yakavharwa uye projective.
1. Semi-yakavharirwa headlight
Semi-yakavharwa headlamp yekuvhenekesa girazi uye girazi rinonamira pamwe chete harigone kuparadzaniswa, girobhu remwenje rinogona kutakurwa kubva kumashure kwegirazi, semi-yakavharwa headlamp mukana wekuti filament yakatsva inongoda kutsiva girobhu, iyo yakashata ndeyekusaisa chisimbiso. . Iyo yakasanganiswa mwenje wemusoro unosanganisa kumberi kutendeuka chiratidzo, kumberi kwehupamhi mwenje, yakakwira danda mwenje uye yakaderera mwenje kuita yakazara, nepo reflector uye pantoscope inogadzirwa kuita yakazara uchishandisa organic zvinhu, uye girobhu rinogona kutakurwa zviri nyore kubva shure. Nemarambi akasanganiswa, vagadziri vemotokari vanogona kugadzira chero mhando yemwenje inoenderana nelens painodiwa kuitira kuti uvandudze mota aerodynamic hunhu, hupfumi hwemafuta uye masitaera emotokari.
2. Mwenje wakavharirwa
Marambi emusoro akavharirwa akakamurwawo kuva mwenje wakavharirwa mwenje uye halogen akavharirwa mwenje.
Iyo optical system yeyakavharirwa headlamp ndeyekusanganisa uye weld iyo reflector uye inofananidzira girazi mune yakazara kuti igadzire bulb imba, uye filament inosungirirwa kune reflexer base. Iyo inoratidzira pamusoro inovhenekerwa ne vacuum, uye mwenje unozadzwa neinert gasi uye halogen. Zvakanakira chimiro ichi kuita kwakanaka kwekuisa chisimbiso, girazi harizosvibiswa nemhepo, kukwirira kwekuratidzira, uye hupenyu hurefu hwebasa. Zvisinei, mushure mokunge filament yapiswa, boka rose rekuvhenekera rinoda kuchinjwa, uye mari yacho yakakwirira.
3. Projective headlamp
Iyo optical system yeprojekiti headlamp inonyanya kuumbwa nemwenje girobhu, ratidziro, shading girazi uye convex inoenderana girazi. Shandisa girazi rakakora kwazvo risina kunyorwa convex, girazi rine oval. Saka dhayamita yaro yekunze idiki kwazvo. Projective headlights ine maviri akatarisisa, yekutanga kutarisa igirobhu uye yechipiri inotarisisa inoumbwa muchiedza. Tarisa mwenje kuburikidza negirazi reconvex worikanda kure. Chakanakira chayo ndechekuti iyo yekutarisa kuita yakanaka, uye nzira yayo yekuratidzira ray ndeye:
(1) Chiedza chinobudisirwa kuchikamu chepamusoro chegirobhu chinodarika nemuratidziri kuenda kune chechipiri chinotariswa, uye chinonangidzirwa kure kure kuburikidza negirazi rinoenderana neconvex.
(2) Panguva imwecheteyo, mwenje unobuditswa kuchikamu chepasi chegirobhu chinoratidzwa negirazi rekuvharisa, rinoratidzwa kumashure kune reflekisi uye rozokandwa kune yechipiri kutarisa, uye rinonangidzirwa kure kure kuburikidza neconvex inoenderana negirazi.
Mukushandiswa kwemotokari, zvinodikanwa zvemwenje wemberi ndezvi: zvese kuve nemwenje wakanaka, asiwo kudzivirira kupofumadza mutyairi wemota iri kuuya, saka kushandiswa kwemwenje kunofanirwa kutarisisa kune zvinotevera pfungwa:
(1) Chengetedza mwenje wepantoscope wakachena, kunyanya kana uchityaira kuchinaya uye muchando, tsvina netsvina zvinoderedza kuita kwemwenje werambi ne50%. Mamwe mamodheru akashongedzerwa nema wiper emwenje uye zvipfapfaidzo zvemvura.
(2) Apo motokari mbiri idzi dzinosangana usiku, motokari mbiri dzinofanira kudzima danda rakakwirira remwenje uye kuchinja kune chiedza chiri pedyo kuti ive nechokwadi chekuchengeteka kwekutyaira.
(3) Kuti uve nechokwadi chekushanda kwechigadziko chemwenje, bhanhire remwenje rinofanira kuongororwa uye kugadziriswa mushure mokunge mwenje unotsiviwa kana mushure mokunge motokari ichityaira 10,000 km.
(4) Gara uchitarisa girobhu remwenje uye mutsara socket uye base iron ye oxidation uye kusunungura, kuve nechokwadi kuti iyo yekubatanidza yekubatanidza kuita yakanaka uye base iron yakavimbika. Kana iyo yekusangana yakasununguka, kana iyo headlamp ikabatidzwa, inoburitsa kuvhunduka kwazvino nekuda kwekudzima kwedunhu, nekudaro kupisa filament, uye kana iyo yakabatana yakasvibiswa, inoderedza kupenya kwerambi nekuda. kusvika pakuwedzera kwekudonhedza kwehutano hwekusangana.
Kana iwe uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonere kana uchida zvigadzirwa zvakadaro.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa MG&MAUXS zvikamu zvemotokari zvinogamuchirwa kutenga.
