Momwe Toyota Hybrid (HSD) imagwirira ntchito

Aliyense akudziwa bwino kuti Toyota HSD hybridization ali ndi mbiri kukhala msonkhano. Chipangizo cha mtundu wa Japan (mgwirizano wa Aisin) chimadziwika osati chifukwa cha luso lake, komanso chifukwa chodalirika kwambiri. Komabe, ndizovuta kumvetsetsa chifukwa cha zovuta zake komanso njira zambiri zogwirira ntchito.

Choncho, tiyesetsa kumvetsa mmene Toyota hybrid chipangizo, wotchuka seri / Parallel HSD e-CVT ntchito. Chotsatiracho chimakulolani kukwera 100% magetsi kapena kuphatikiza magetsi ndi matenthedwe. Apa ndikutenga mutu wovuta, ndipo nthawi zina ndimayenera kuufewetsa pang'ono (ngakhale izi sizimasokoneza malingaliro ndi mfundo).

Tsopano dziwani kuti ma HSD transmissions amapangidwa ndi Aisin (AWFHT15), omwe Toyota amakhala ndi 30%, ndikuti amapereka ma hybrid komanso osagwiritsa ntchito gulu la PSA zikafika ku EAT kapena e-AT8. mabokosi. (hybrid2 ndi haibridi4). Tsopano tili m'badwo wachinayi pankhani ya chitukuko chaukadaulo. Ngakhale mfundo yonse imakhalabe yofanana, kusintha kwakung'ono kumapangidwira pakati pa mapulaneti a pulaneti kapena masanjidwe kuti akwaniritse kukhazikika komanso kuchita bwino (mwachitsanzo, kutalika kwa chingwe kumachepetsa kutayika kwa magetsi).

Kufotokozera mopanga

Ngati mukufuna kuwona bwino momwe HSD imagwirira ntchito, nayi kufotokozera mwachidule. Muyenera kupita patsogolo m'nkhaniyi kuti mufufuze mozama kapena kuyesa kumvetsetsa zomwe zikukuvutani pakadali pano.

Nayi udindo wa gawo lililonse komanso mawonekedwe aukadaulo a HSD:

• ICE (Internal Combustion Engine) ndi injini yotentha: mphamvu zonse zimachokera kwa izo, choncho ndilo maziko a chirichonse. Imalumikizidwa ku MG1 kudzera pa sitima ya epicyclic.
• MG1 imagwira ntchito ngati jenereta yamagetsi (yoyendetsedwa ndi injini yotentha) komanso chosinthira cha gearbox. Imalumikiza ICE ku MG2 kudzera m'mapulaneti (mapulaneti). MG2 imalumikizidwa mwachindunji ndi mawilo, kotero ngati mawilo atembenuka, amatembenuka, ndipo ngati atembenuzanso mawilo (mwachidule, palibe kusagwirizana pakati pawo) ...
• MG2 imagwira ntchito ngati traction motor (kutalika kwa 2 km kapena 50 km pa plug-in / rechargeable) komanso ngati jenereta yamagetsi (deceleration: regeneration)
• Zida za Planetary: Zimagwirizanitsa MG1, MG2, ICE ndi mawilo pamodzi (izi sizimasokoneza zinthu zina kukhala zotetezedwa pamene zina zikuzungulira, muyenera kuphunzira ndi kumvetsa momwe zida za mapulaneti zimakhalira ndi moyo). Komanso zikomo kwa iye, timakhala ndi kusintha kosalekeza / kuchepa, choncho ndi iye amene amaimira gearbox (chiwerengero cha gear chimasintha, chomwe chimachititsa kuti chiwonongeke kapena "kubwerera": kugwirizana pakati pa ICE ndi MG1)

Kuchepetsa kumaphatikizapo kuwonjezera kapena kuchepera kwa kayendedwe ka injini yoyaka mkati (zotentha) ndi MG2 (yomwe imalumikizidwa mwamphamvu ndi mawilo, tisaiwale).

Wophunzitsa wa Hybrid Planetary Gear

Kanemayu ndiwabwino kuti mumve momwe Toyota hybridization imagwirira ntchito.

Chatsopano: Njira Yotsatizana Pamanja pa Toyota HSD Hybrid?

Akatswiriwa adatha kufanizira (pang'ono ..) malipotiwo posewera momwe MG1 ingathyolere kapena kubwerera m'mbuyo mwanjira yosapita patsogolo kuti apeze malipoti omveka bwino. Chiŵerengero cha magiya chimapangidwa ndi MG1, chomwe "chimazembera" cholimba kapena chocheperapo chimagwirizanitsa ICE ndi MG2 (MG2 = motor traction motor, komanso, koposa zonse, mawilo). Chifukwa chake, kuchepa uku kumatha kukhala kwapang'onopang'ono kapena "kugwedezeka" kutengera momwe wogawa mphamvu MG1 amawongolera.

Zindikirani, komabe, kuti kusintha kwa magiya sikumveka pakulemedwa pang'ono ... Ndipo pakulemedwa kwathunthu (kuthamanga kwakukulu) timabwereranso kumasinthasintha mosalekeza chifukwa iyi ndiyo njira yokhayo yopezera magwiridwe antchito abwino kwambiri ndi dongosololi (kompyuta chifukwa chake imakana. kusintha magiya kuti muthamangitse kwambiri).

Chifukwa chake, njirayi imagwiritsidwa ntchito kwambiri pakutsika kwa injini yotsika kuposa kuyendetsa masewera.

Izi ndi momwe zimawonekera. Tsoka ilo, pakudzaza kwathunthu, timataya mawonekedwe otsatizana ndipo sitikumvanso magiya.

Mabaibulo angapo?

Kupatula mibadwo yosiyana, dongosolo la THS / HSD / MSHS monga limagwiritsidwa ntchito ku Toyota ndi Lexus lili ndi mitundu iwiri yayikulu. Yoyamba komanso yodziwika kwambiri ndi yodutsa, yomwe lero ili mu Aisin AWFHT15 (kumayambiriro kwa zaka za m'ma 90 idatchedwa THS ya Toyota Hybrid System. Tsopano ndi HSD ya Hybrid Synergy Drive). Zimabwera m'mitundu iwiri yocheperako: Prius / NX / C-HR (yayikulu), corolla ndi Yaris (yaing'ono).

Pano pali kufalitsa kwamakono (Prius 4) HSD kuchokera kumitundu yopingasa (tsopano pali mitundu iwiri yosiyana, iyi ndi yayikulu). Ndiwophatikizika kwambiri kuposa momwe mukuwonera pansipa (osati yomwe ili pansi pautali, ngakhale pansipa...)

Bwererani ku 1:00 mphindi kuti muwone momwe AWFHT15 ingapangire malipoti. Zodabwitsa ndizakuti, "kudumpha mwachangu" kodziwika bwino sikumvekanso injini ikadzaza ... Izi ndichifukwa choti chipangizocho chimagwira bwino ntchito (chronograph) pamawonekedwe amitundu, kotero kulemedwa kwathunthu kumapangitsa kuti pakhale kusinthasintha kosalekeza.

Kodi Toyota hybrid imagwira ntchito bwanji?

Ndiye mfundo yayikulu ya chipangizo chosakanizidwa cha HSD ndi chiyani? Tikadati tifotokoze mwachidule izi, titha kunena za injini yotentha yomwe imagwira ntchito ndi ma mota / ma jenereta awiri (galimoto yamagetsi nthawi zonse imasinthidwa) komanso ma torque awo (a injini iliyonse) amawongoleredwa ndikuwongoleredwa ndi sitima yapadziko lonse lapansi, koma komanso mphamvu yamagetsi (ndi njira yamagetsi) yoyendetsedwa ndi wogawa mphamvu ("inverter" mu Chingerezi). Zida zochepetsera (CVT gearbox) zimayendetsedwa pakompyuta, zomwe zimapangitsa kuti injini ya MG1 igwire ntchito mwanjira inayake, komanso kudzera pamagetsi apakati, omwe amalola kuti mphamvu zingapo ziphatikizidwe kuti zitulutse imodzi.

Injini imatha kuchotsedwa kwathunthu kuchokera kumawilo, komanso kudzera pagalimoto yamapulaneti ...

Mwachidule, ngakhale titafuna kufewetsa, timamvetsetsa kuti sizingakhale zophweka kutengera, choncho tidzaganizira kwambiri mfundo zoyambirira. Komabe, ndakuikirani kanema mu Chingerezi wofotokozera mwatsatanetsatane, kotero ngati mukufuna kukankhira, muyenera kutero (ndi chilimbikitso ndi ma neuron athanzi, inde).

Nayi Prius 2, yomwe ndi yocheperako kuposa yomwe ndidakuwonetsani pamwambapa. Onani momwe adawunikira A / C kompresa (buluu kumanzere kwa injini). Zowonadi, mosiyana ndi makina onse "abwinobwino", amayendetsedwa ndi mota yamagetsi. Mawilowa amalumikizidwa ndi unyolo womwe ukhoza kuwoneka pagawo lapakati kumanja (pakati pomwe pamagetsi amagetsi).

chosinthira zamagetsi pafupi

M'mbiri, tikuwona imodzi mwamayimidwe a magudumu olumikizidwa ndi unyolo kudzera kusiyanitsa.

Zosiyanasiyana ntchito modes

Tiyeni tiwone mitundu yosiyanasiyana ya kachipangizo kachipangizo komanso, m'njira, chifukwa chake imatengedwa ngati serial / parallel, pomwe nthawi zambiri makina osakanizidwa amakhala amodzi kapena ena. Njira yanzeru yopangira HSD imalola onse awiri, ndipo izi zimapangitsanso kuti zikhale zovuta ...

Toyota HSD chipangizo: zambiri ndi zomangamanga

Nawa kamangidwe kachipangizo ka HSD kamitundu yambiri kuti kakuthandizeni kupanga kulumikizana pakati pazigawo.

Chithunzicho ndi chozondoka poyerekeza ndi chithunzi chapamwamba chifukwa chatengedwa kuchokera kumbali ina ... Ndinatenga chithunzi cha Prius 2 ndipo chifukwa chake pali unyolo pano, matembenuzidwe amakono alibe, koma mfundoyi sikusintha. Mulimonsemo (ngakhale unyolo, shaft kapena gear ndizofanana.

Apa pali limagwirira mwatsatanetsatane, chifukwa ziyenera kumveka kuti zowawa zimapezedwa pano chifukwa cha mphamvu yamagetsi yamagetsi pakati pa rotor ndi stator MG1.

MG1 imalumikizidwa ndi injini kudzera pa pulaneti ya giya (yobiriwira) ya pulaneti ya zida. Ndiko kuti, kutembenuza MG1 rotor (gawo lapakati), injini yotentha imadutsa mumlengalenga. Ndaunikira sitimayi ndi injini mumtundu umodzi kuti tiwone bwino kulumikizana kwawo. Kuphatikiza apo, ndipo sizinawonetsedwe pazithunzi, satellite yobiriwira ndi buluu wapakati dzuwa zida MG1 zimalumikizidwa bwino (pali kusiyana pakati pawo), monganso korona (m'mphepete mwa sitima). ndi satellite yobiriwira ya injini yotentha.

MG2 imalumikizidwa mwachindunji ndi mawilo kudzera mu unyolo, komanso imayendetsa zida zakunja zapadziko lapansi (korona ndi buluu wakuda, ndinasankha mtundu womwewo kuti utalikitse zida zapapulaneti kuti tiwone bwino kuti zikugwirizana ndi MG2. )...

Nayi bokosi la pulaneti kutsogolo, osati pazithunzi pamwambapa, titha kuwona bwino kulumikizana pakati pa magiya osiyanasiyana okhudzana ndi MG1, MG2 ndi ICE.

Chovuta chagona pakumvetsetsa mfundo ya sitima yapadziko lapansi, podziwa kuti mayendedwe amkati samagwirizana malinga ndi njira zoyendetsera, komanso kuthamanga ...

Palibe zogwirira?

Mosiyana ndi ma transmissions ena onse, HSD siyikusowa cholembera kapena chosinthira (mwachitsanzo, CVT imafunikira torque converter). Apa ndipamene mphamvu yamagetsi imamangiriza mawilo ku injini kudzera mu sitima yapadziko lapansi chifukwa cha MG1. Ndiye ndi rotor ndi stator chakumapeto (MG1) kuti ndiye kupanga zotsatira za kukangana: pamene inu atembenuza galimoto magetsi ndi dzanja, kukana kuwuka, ndipo ndi yotsirizira kuti timagwiritsa ntchito pano ngati zowalamulira.

Ndibwino kwambiri kuti, pakakangana (kusiyana kwa liwiro pakati pa stator ndi ozungulira, chifukwa chake pakati pa mota ndi mawilo), magetsi amapangidwa. Ndipo magetsi amenewo adzasungidwa mu batire!

Ichi ndichifukwa chake dongosolo la HSD limaonedwa kuti ndi lanzeru kwambiri, chifukwa limapereka mphamvu zochepa zochepetsera mphamvu pobwezeretsa mphamvu panthawi ya kukangana. Pa clutch yachikale, timataya mphamvuyi pakutentha, apa imasinthidwa kukhala magetsi, omwe timabwezeretsa mu batri.

Choncho, palibenso kuvala kwa makina, popeza palibe kukhudzana kwa thupi pakati pa rotor ndi stator.

Ikayimitsidwa, injiniyo imatha kuthamanga popanda kuyima chifukwa mawilo samatsekereza injini (zomwe zikanatheka tikadayimitsa panjira popanda kuzimitsa). Zida za dzuwa za buluu (zomwe zimatchedwanso zopanda ntchito) ndi zaulere, choncho zimalekanitsa mawilo amoto (motero magiya obiriwira a mapulaneti). Kumbali ina, ngati zida za dzuŵa ziyamba kulandira torque, zimagwirizanitsa magiya obiriwira ku korona, ndiyeno mawilo amayamba kuzungulira pang'onopang'ono (kugwedezeka kwamagetsi).

Ngati zida za dzuwa zili zaulere, mphamvu sizingapatsidwe korona.

Pamene rotor imazungulira, kukangana kumapangidwa mu stator, yomwe imayambitsa torque, ndipo torque iyi imatumizidwa ku giya la dzuwa, lomwe limatseka ndipo pamapeto pake limazungulira mbali ina. Zotsatira zake, kulumikizana kumapangidwa pakati pa shaft yamoto pakatikati ndi giya la mphete pamphepete (giya = mawilo). Dziwani kuti chipangizocho chimathandizanso kuyimitsa ndikuyamba: mukafuna kuyambitsa, ndikwanira kutsekereza zida zadzuwa mwachidule kuti injini yoyaka moto ilandire torque kuchokera ku MG2 yolumikizidwa ndi gudumu loyendetsedwa (izi zimayamba ngati choyambira. . Amachita. Zachikale).

Kotero, mwachidule:

• Ikakhala yoyima, injini imatha kuzungulira chifukwa kulumikizana pakati pa ekisi ya injini ndi giya ya mphete sikunakhazikitsidwe: zida zadzuwa ndi zaulere (ngakhale Prius imatseka nthawi zambiri ikayima kuti isunge mafuta)
• Powonjezera liwiro la injini, rotor imazungulira mwachangu kuti ipange mphamvu yamagetsi, yomwe imatumiza torque ku giya ladzuwa: kupanga kulumikizana pakati pa axis yamoto ndi giya la mphete.
• Pamene kugwirizana kupangidwa, liwiro la mota axis ndi gudumu mphete ndi ofanana
• Pamene liwiro la mawilo lifika mofulumira kuposa injini, zida za dzuwa zimayamba kuyendayenda kumbali ina kuti zisinthe chiŵerengero cha zida (zonse zitatsekedwa, zimayamba "kupukuta" kuti ziwonjezere kuthamanga kwa dongosolo). M'malo mwake, tinganene kuti, polandira torque, zida za dzuwa sizimangolumikiza ma axles agalimoto ndi gudumu loyendetsa, komanso zimawapangitsa kuti azithamanga kwambiri (osati mabuleki okha "kukana", komanso amawapangitsa kuti azizungulira. njira yotsatira)

100% magetsi mode

Apa ma ICE (thermal) ndi MG1 motors sakhala ndi gawo lapadera, ndi MG2 yomwe imazungulira mawilo chifukwa cha magetsi omwe amachokera ku batri (kotero mphamvu yochokera ku chemistry). Ndipo ngakhale MG2 itembenuza rotor ya MG1, sizimakhudza injini yotentha ya ICE, choncho palibe kukana komwe kumatidetsa nkhawa.

Njira yolipirira itayimitsidwa

Injini yotentha ikugwira ntchito pano, yomwe imazungulira MG1 kudutsa sitima yapadziko lapansi. Mwanjira iyi, magetsi amapangidwa ndikutumizidwa kwa wogawa mphamvu, omwe amatsogolera magetsi ku batri yokha.

Makina obwezeretsa mphamvu

Iyi ndi njira yodziwika bwino ya "B" (regenerative braking), yomwe imatha kuwonedwa pa mfundo ya giya (pamene mukukankhira, pali mabuleki ochulukirapo okhudzana ndi MG2 kinetic energy recuperation, kukana ndi electromagnetic). Mphamvu ya inertia / kinetic imachokera kumawilo motero imapita ku MG2 kudzera pamagiya amakina ndi unyolo. Popeza mota yamagetsi imatha kusinthidwa, ipanga magetsi: ndikatumiza madzi ku mota yamagetsi, iyatsa, ndikayatsa magetsi oyimitsa ndi dzanja, ipanga magetsi.

Mphamvu yamagetsi iyi imapezedwanso ndi wogawa kuti atumize ku batri, yomwe idzawonjezeredwa.

Injini yamagetsi ndi kutentha zimagwira ntchito limodzi

Pa liwiro lokhazikika komanso pa liwiro labwino, ndiko kuti, nthawi zambiri, mawilo adzayendetsedwa ndi mphamvu ya magetsi (MG2) ndi injini zotentha.

Injini yotentha ya ICE imayendetsa zida zapadziko lapansi, zomwe zimapanga magetsi mu MG1. Izi zidzasinthiranso mphamvu yamakina kumawilo, popeza zida zapadziko lapansi zimalumikizidwanso nawo.

Apa ndipamene zovuta zimatha kukhala zolepheretsa, chifukwa kutengera kuthamanga kwa ma giya a mapulaneti sikudzakhala kofanana (makamaka kuwongolera kwa magiya ena).

Ma gearbox amtundu wa CVT (kusintha kosalekeza komanso kopitilira muyeso ngati ma scooters) amapangidwa ndi kulumikizana kwa ma voltages pakati pa ma motors (chifukwa cha mphamvu ya maginito yomwe imayambitsidwa ndi madzi omwe amadutsa pamakoyilo: gawo lopangidwa ndi ma elekitiroma) komanso zida zapadziko lapansi. . yomwe imalandira mphamvu zamakanema angapo. Zabwino zonse kuti mupeze izi mosavuta, ngakhale kanema yemwe ndikukuyikani angakuthandizeni kutero.

Mphamvu yayikulu

Izi ndizofanana ndi ndime yapitayi, kupatula kuti pano tikutenganso mphamvu zamagetsi zomwe batri lingapereke, kotero MG2 imapindula ndi izi.

Nayi mtundu waposachedwa wa Prius 4:

Pulagi-mu / mtundu wowonjezeranso?

Chosankha chokhala ndi batire yowonjezereka, kulola 50 km pagalimoto yamagetsi yonse, chimangokhala kukhazikitsa batire yayikulu ndikuyika chipangizo chomwe chimalola kuti batire igwirizane ndi gawoli.

Muyenera kudutsa wogawira mphamvu ndi inverter poyamba kuti muyang'anire kusiyana kwa mphamvu ndi mitundu yosiyanasiyana ya madzi: AC, DC, etc.

Mtundu wa HSD 4X4?

Monga mukudziwira, mtundu wa 4X4 ulipo pa Rav4 ndi NX 300H ndipo udapangidwa kuti uwonjezedwe ku chitsulo chakumbuyo, monga PSA's E-Tense ndi HYbrid / HYbrid4. Choncho, ndi kompyuta yomwe imatsimikizira mphamvu yokhazikika ya mawilo a kutsogolo ndi kumbuyo, omwe, motero, alibe kugwirizana kwakuthupi.

Chifukwa chiyani serial / parallel?

Chipangizocho chimatchedwa serial/parallel chifukwa chimatchedwa "series" mukakhala mu 100% magetsi. Choncho, timagwira ntchito mofanana ndi BMW i3, injini yotentha ndi jenereta yamakono yomwe imadyetsa batri, yomwe imayendetsa galimotoyo. M'malo mwake, ndi njira iyi yogwiritsira ntchito, injini imachotsedwa kwathunthu ku mawilo.

Imatchedwanso parallel pamene injini imalumikizidwa ndi magudumu kudzera pa chipangizo cha mapulaneti. Ndipo izi zimatchedwa batch build (onani Zosiyanasiyana zimamanga apa).

Kodi Toyota ikuchita zochuluka kwambiri ndi makina ake?

Pamapeto pa nkhaniyi, Ndikufuna kunena pang'ono tirade. Zowonadi, Toyota imalankhula zambiri za plug-in hybrid yake, ndipo ndizomveka komanso zovomerezeka. Komabe, zikuwoneka kwa ine kuti chizindikirocho chapita kutali kwambiri m'njira ziwiri. Choyamba, kupanga luso laukadaulo, kutanthauza kuti lidzapulumutsa dziko lapansi mwanjira ina, ndikuti, kwenikweni, mtunduwo ukuyambitsa kusintha komwe kungatipulumutse tonse. Zedi, imachepetsa kugwiritsa ntchito mafuta, koma sitiyeneranso kutengeka, minivan ya dizilo yosakanizidwa imagwira ntchito mofananamo, ngati sichoncho, nthawi zina.

Chifukwa chake Toyota ikugwiritsa ntchito mwayi wotsutsana ndi dizilo kuti iwonjezere wosanjikiza womwe ndikuganiza kuti ndiwokongoletsedwa pang'ono pano pakutha, nayi imodzi:

Malonda a pa TV - Mitundu ya Hybrid - Timasankha Hybrid

Ndiye pali vuto lolumikizana. Mtundu wa ku Japan umakhala ndi mauthenga ambiri chifukwa chakuti galimotoyo sifunikira kulipira kuchokera ku mains, ngati kuti ndi mwayi waukadaulo pa mpikisano. Izi ndizosocheretsa pang'ono chifukwa ndizosautsa kuposa china chilichonse ... Magalimoto osakanizidwa omwe amatha kuyimbidwa sayenera kutero, iyi ndi njira yomwe imaperekedwa kuwonjezera kwa mwini wake! Kotero chizindikirocho chimatha kuchotsa chimodzi mwa zolakwikazo ngati mwayi, ndipo icho chikadali champhamvu, sichoncho? Chodabwitsa ndichakuti, Toyota ikugulitsa mitundu yake ya Prius, ndipo akuyenera kukhala abwinoko ... Nayi imodzi mwamalonda:

Simufunikanso kulichangitsa? M'malo mwake, ndidzati: "woonda, palibe njira yochitira ..."
