Kodi chosinthira torque chimagwira ntchito bwanji?

Chigawochi, chomwe chimatchedwa torque converter kapena torque converter, chimayikidwa muzotengera zodziwikiratu ngati clutch. Chifukwa chake, imayimira kugwirizana pakati pa injini ndi mawilo (kapena m'malo mwake gearbox yomwe imayikidwa pakati pawo).

Imakonzekeretsa ma transmissions odziwikiratu omwe amatha kudziwika ngati wamba (ndi magiya a mapulaneti), mosiyana ndi ma robotic (clutch imodzi kapena iwiri, yofanana ndi magiya ofanana). CVTs amagwiritsanso ntchito chosinthira, popeza galimoto iyenera kuyimitsa popanda kuyimitsa injini ndikuyimitsa.

Malo ndi mawonekedwe a zinthu zimatha kusiyana kwambiri kuchokera ku transducer imodzi kupita ku ina.

Iyi ndi gearbox ya Mercedes' 9-speed longitudinal gearbox. Chosinthira chili kumanzere kofiyira, ndi magiya ndi zomangira za gearbox kumanja.

Mfundo yayikulu

Ngati clutch wamba imakupatsani mwayi wolumikizana / kugwirizanitsa kusinthasintha kwa shaft ya injini ndi kuzungulira kwa bokosi la gear (ndipo mawilo) pogwiritsa ntchito kugunda kwa disk (clutch) motsutsana ndi flywheel, ngati torque, chosinthira chimakhala. mafuta amene adzasamalira ... Palibenso kukangana kwakuthupi pakati pa zinthu ziwiri.

Muvi wofiyira ukuwonetsa njira yomwe mafuta amayenda. Imasuntha kuchoka ku turbine kupita ku ina mozungulira motsekeka. Stator yapakati imatsimikizira magwiridwe antchito abwino kwambiri. Pampu imayendetsedwa ndi injini, ndipo turbine imayendetsedwa ndi kutuluka kwa mafuta, komwe kumayendetsedwa ndi mpope, dera limatsekedwa. Ngati titha kujambula fanizo, titha kufananiza dongosolo lomwe lili ndi mafani awiri omwe adayikidwa maso ndi maso. Pozungulira chimodzi mwa ziwirizo, mphepo yopangidwayo idzazungulira ina kumbali ina. Kusiyana kokha ndiko kuti transducer sasuntha mpweya, koma mafuta.

Kuti izi zitheke, makinawa amagwiritsa ntchito ma hydraulic current ngati kuti ndi mphepo (chifukwa cha chidwi chanu, dziwani kuti ma equation amadzimadzi ndi mpweya ndi ofanana, onse amatengera zamadzimadzi) motero amagwira ntchito pafupi kwambiri ndi fan. ... Choncho, m'malo mpweya mpweya, ife ventilate mafuta ndi kubwezeretsa mphamvu (hydrokinetic mphamvu) wa otaya kwaiye atembenuza wina "propeller". Chifukwa dongosolo lomwe likufotokozedwa apa ndi lodzaza ndi mafuta.

Nanga bwanji hydrotransformer?

Chosinthira ma hydraulic (chifukwa cha stator) chimalola kuti torque yochulukirapo ipezeke pakulowetsa ku bokosi la giya kuposa momwe injini imatulutsira.

Zowonadi, pampu yotumizira (motor) imazungulira mwachangu kuposa turbine yolandila (s) nthawi zambiri, zomwe zimapangitsa kuti turbine ipindule ndi torque yapamwamba (mphamvu yomwe liwiro lake lachepetsedwa limapereka torque yapamwamba). Ndikukupemphani kuti muwerenge nkhaniyi kuti mudziwe bwino ubale womwe ulipo pakati pa mphamvu ndi torque.

Chodabwitsa ichi ndi chofunikira kwambiri chifukwa pali kusiyana kwa liwiro lozungulira pakati pa mpope ndi turbine. Mwachitsanzo (ziwerengero zimatengedwa mwachisawawa), ngati makokedwe ndi 160 Nm pa crankshaft linanena bungwe pa 2000 rpm, pakhoza kukhala 200 Nm pa athandizira gearbox (motero dzina "makokedwe Converter"). Izi ndichifukwa cha mtundu wa kuchuluka kwa kuthamanga kwamafuta mumayendedwe osinthira (stator imayambitsa pulagi, onani kanema pansi pa tsamba). Kumbali ina, ma torque ndi (pafupifupi) ofanana pamene mpope ndi turbine zimafika pa liwiro lomwelo.

Mwachidule, zonsezi zikusonyeza kuti chosinthira makokedwe adzapereka makokedwe kwambiri kwa bokosi gearbox kuposa injini angapereke (izi ndi pamene pali delta kwambiri pakati turbine ndi kasinthasintha mpope). Galimoto yopanda kanthu imawoneka yamphamvu kwambiri pama revs otsika ikaphatikizidwa ndi BVA (chifukwa chake chifukwa cha chosinthira osati gearbox).

Pompo ndi turbine

Shaft ya injini (crankshaft) imalumikizidwa ndi cholumikizira (kudzera pa flywheel) chotchedwa mpope. Omaliza amasakaniza mafuta chifukwa cha mphamvu ya injini, chifukwa chake amatchedwa mpope (popanda mphamvu ya injini yomwe imayendetsa, imakhala turbine yosavuta ...).

Pampu iyi imapopa mafuta mbali yofanana ndi turbine ina yofanana, koma yokhala ndi masamba opindika. turbine yachiwiri iyi, yolumikizidwa ndi bokosi la giya, imayamba kuzungulira chifukwa cha mphamvu yomwe imapangidwa ndikuyenda kwamafuta: chifukwa chake, torque imafalikira pakati pa injini ndi bokosi la gear (lomwe limalumikizidwa ndi mawilo kudzera pamiyendo ya propeller) pogwiritsa ntchito mafuta okha. ! Zimagwira ntchito ngati turbine yamphepo: mphepo imayimiridwa ndi mpope (turbine yolumikizidwa ndi injini), ndipo turbine yamphepo ndiyo yolandila.

Choncho, kumverera kwa kutsetsereka pakati pa magiya (kapena pamene galimoto ikusuntha kuchoka ku mpumulo) kumagwirizana ndi kusamutsidwa kwa mphamvu kudzera mumadzimadzi. Podziwa kuti pompano imathamanga mofulumira, m'pamenenso turbine yolandira imathamanga kwambiri mpaka ifike pa liwiro lofanana ndi mpope.

Pampu imalumikizidwa ndi injini

Ndikayima, pamakhala phokoso (kusuntha kwapang'onopang'ono kokha mu Drive) chifukwa mpope ikupitirizabe (injini imathamanga) choncho imasamutsira mphamvu ku turbine yolandira. Pachifukwa chomwechi, magalimoto atsopano ali ndi batani la Hold, lomwe limakupatsani mwayi woletsa kuphulika pogwiritsa ntchito mabuleki (chilichonse chimayang'aniridwa ndi kompyuta yomwe imaphwanya magudumu. Mukaimirira, imamasula mabuleki akangolandira pempho. kuchokera pa accelerator pedal).

Komabe, kumbukirani kuti chosinthira makokedwe chimalola injini kuyimitsa popanda kuyimitsa chifukwa pampu imatha kupitilizabe ngakhale turbine yolandirayo itayimitsidwa, ndiye kuti ma hydraulic "slip" amapezeka.

The turbine yolumikizidwa ndi gearbox

Komanso dziwani kuti pampuyo imalumikizidwa ndi unyolo womwe umayendetsa mpope wamafuta otumizira, womwe umatulutsa magiya ambiri omwe amapanga.

stator

Amatchedwanso riyakitala, ndiye amene adzachita ngati chosinthira makokedwe. Popanda awiri omaliza, mpope + turbine amayenerera kokha ngati hydraulic coupling.

Ndipotu, ndi turbine yaing'ono kuposa ena awiri, omwe ali ndendende pakati pa ena awiri ... Udindo wake ndi kukonzanso kayendedwe ka mafuta kuti akwaniritse zomwe akufuna, kotero kuti dera lomwe mafuta amayendamo ndi losiyana. Zotsatira zake, torque yomwe imaperekedwa kugawo la gearbox imatha kukhala yokwera kwambiri kuposa ya injini. Zowonadi, izi zimapangitsa kuti pakhale plugging yomwe imakanikizira mafuta pagawo linalake mu unyolo, zomwe zimawonjezera mphamvu yoyenda mkati mwa chosinthira makokedwe. Koma izi zimatengera liwiro la kasinthasintha wa turbine ndi mpope.

Axle / clutch

Komabe, ngati kugwirizana kwa gearbox ndi injini kunkachitika kokha ndi mafuta, mphamvu ya chirichonse chikanakhala chochepa. Popeza pali kutaya mphamvu pakati pa ma turbines awiri chifukwa cha kutsetsereka (turbine sichimafika pa liwiro lofanana ndi mpope), zomwe zimapangitsa kuti anthu azidya kwambiri (ngati izi sizinali vuto mu 70s ku USA, chinthu chosiyana kwambiri. lero).

Pofuna kuthana ndi izi, pali clutch (yosavuta ndi yowuma, kapena yonyowa ma disks ambiri, mfundoyi ndi yofanana) yomwe imakhazikika pamene mpope imazungulira pafupifupi liwiro lofanana ndi turbine yolandira (izi zimatchedwa bypass clutch). ). Chifukwa chake, zimalola kukhazikika kotetezeka (komanso ndi kusinthasintha kochepa kuti mupewe kusweka, monga pa clutch iliyonse, chifukwa cha akasupe omwe mumatha kuwonanso pa gearbox ya 9-speed gearbox yomwe ikuwonetsedwa kumayambiriro kwa nyengo. ”Nkhani). Chifukwa cha izi, titha kupeza mabuleki amphamvu kwambiri a injini.

bypass clutch

Pano tili mu gawo la kukakamiza ma multi-disc ndi kuthamanga kwa hydraulic komwe kumakankhira ma diski kutsutsana.

Pambuyo popanga jumper, turbine ndi mpope zimakhala zofanana, ndipo kusakaniza kwa mafuta pakati pa magawo awiriwa sikudzachitikanso. Chosinthiracho chakhala chokhazikika ndipo chimachita ngati banal driveshaft ...

Kodi chosinthira ma torque chimagwira ntchito bwanji pamagetsi odziwikiratu? Galimoto Yamagetsi & Kukonza Magalimoto Ophatikizana⚡

Ubwino wake?

Chosinthira ma torque chimadziwika kuti chimatenga nthawi yayitali kuposa clutch wamba (komabe, ziwombankhanga zonyowa zamitundu yambiri zimakhala zolimba ngati zosinthira) ndikusunga makina ena onse (maketani onse).

Zowonadi, ntchito yosalala (mwa njira, yosangalatsa kwambiri) imasunga zinthu mwadzidzidzi (kaya pamlingo wa injini kapena chassis), pomwe bokosi lamanja kapena loboti limasokoneza pang'ono lonse. Pa mtunda wa makilomita oposa 100, kusiyana kumamveka kwenikweni pakulimba kwa zigawozo. Mwachidule, nthawi yabwino yogula yogwiritsidwa ntchito. Osanenapo, dongosololi limatetezedwa kwa aliyense amene sangathe kusintha magiya. Chifukwa ndi kufala pamanja, ndi zokwanira kwa mwiniwake kusintha magiya molakwika kwa makilomita oposa 000 kuvulaza zimango, zimene sitinganene kuti mtundu uwu wa hydraulic clutch (omwe salamulidwa ndi dalaivala).

Kuphatikiza apo, palibe clutch yovala (yodutsayo imakhala ndi kupsinjika pang'ono kotsetsereka ndipo pomwe ma disc ambiri samatulutsa). Izi zimaperekanso ndalama zabwino, ngakhale kuli kofunikira kuganiziranso kukhetsa chosinthira nthawi ndi nthawi (mafuta nthawi zambiri amagwiritsidwa ntchito ndi ma gearbox ena onse) (makamaka 60 aliwonse, komanso 000).

Pomaliza, kutembenuka kwa torque kulipo kumapangitsa kukhala kosavuta kuchepetsa malipoti popanda kukhudza kwambiri kuvomerezedwa. Ichi ndichifukwa chake panali ma BVA ambiri zaka zingapo zapitazo.

Zoyipa?

Chotsalira chokha, monga momwe ndikudziwira, chikugwirizana ndi zosangalatsa zoyendetsa galimoto. Pali chotchingira chochuluka kwambiri pakati pa mota ndi ma tcheni onse okokera.

Ndicho chifukwa chake ku Mercedes tinasintha mokondwera chosinthira chamitundu yambiri pa 63 AMG (onani Speedshift MCT). Zosavuta komanso zopanda kutsetsereka (ndi kutsekereza kwabwino, ndithudi, zimatengera njira zoyendetsera galimoto), zimakuthandizani kuti muchepetse inertia ya injini. Nthawi yoyankha mofulumizitsa nayonso ndiyofupika.

Titha kuwonetsanso kuti ma BVA akale pang'ono amatsika pang'ono chifukwa chakumangika kwapang'onopang'ono kwa ma multi-disc (pali gulu lapadera la ma multi-disc mu lipoti lililonse lomwe limalola kuti magiya a mapulaneti atsekedwe). Wodzigudubuza alibe kugwirizana kwenikweni ndi chosinthira makokedwe (sikuzembera mpaka nthawi yonyamuka, ndiye pafupifupi 0 mpaka 3 km / h).
