Isebenza kanjani kahle i-Dsg 7

I-DSG (kusuka ku-direct shift gearbox - “direct gearbox”) iyi-robotic gearbox enama-clutch ama-2 futhi ilawulwa iyunithi kagesi (mechatronics). Izinzuzo zalokhu kushintshwa kwamagiya asheshayo ngenxa yokumataniswa kwama-clutch, amandla okulawula ngesandla nokonga uphethiloli, kanti ububi buwukuphila kwesevisi emfushane, izindleko zokulungisa, ukushisa ngokweqile ngaphansi komthwalo kanye nokungcoliswa kwezinzwa.

Ukusebenza kahle kwebhokisi le-7-speed DSG kukuvumela ukuthi unwebe impilo ka-gearbox futhi unciphise ingozi yokuphuka ngenxa yokuguga kwama-bearings, ama-bushings nezinye izingxenye zokungqubuzana.

Imithetho yokushayela i-DSG-7

Ama-clutch ebhokisi le-robotic awaningi kakhulu. I-1st inesibopho sokufakwa kwamagiya angabhanqiwe, kanye ne-2 - ebhanqiwe. Izindlela zivula kanyekanye, kodwa thintana nediski eyinhloko kuphela lapho imodi ehambisanayo ivuliwe. Isethi yesi-2 yenza ukushintsha ngokushesha.

Ama-clutch e-DSG-7 angaba "omile" futhi "amanzi". Umsebenzi wokuqala wokungqubuzana ngaphandle kokupholisa uwoyela. Lokhu kunciphisa ukusetshenziswa kukawoyela izikhathi ezingu-4,5-5, kodwa kunciphisa isivinini esiphezulu senjini futhi kwandisa ingozi yokulimala kwebhokisi lika-gearbox ngenxa yokugqoka.

Ama-DSG "Dry" afakwe ezimotweni ezincane ezinenjini enamandla aphansi. Nakuba zenzelwe ukushayela edolobheni, ezinye izimo zokushayela (isiminyaminya sezimoto, izinguquko zemodi, ukudonsa) zingagcwala ukushisa ngokweqile.

I-DSG-7 "emanzi" ingamelana nemithwalo esindayo: i-torque ene-transmission enjalo ingaba ngu-350-600 Nm, kanti "eyomile" ingaba ngaphezu kuka-250 Nm. Ngenxa yokupholisa uwoyela we-hydraulic, ungasetshenziswa ngemodi enzima kakhulu.

Ukuhamba kahle esiminyaminyeni sezimoto edolobheni

Ngesikhathi ushayela, i-DSG iyazishintsha iye egiyeni eliphezulu. Lapho ushayela, lokhu kunganciphisa kakhulu ukusetshenziswa kukaphethiloli, kodwa ngokuma njalo esiminyaminyeni sethrafikhi, kugugisa ukudluliselwa.

Ngenxa yemvelo ka-gearbox, le shift ibamba womabili ama-clutch. Uma umshayeli engasheshisi ngesivinini esifunayo noma ecindezela ibhuleki ngenkathi ehamba esiminyaminyeni sezimoto, khona-ke ngemuva koshintsho lokuqala kukhona ukubuyela egiyeni eliphansi, lokuqala.

Ukushayela nge-Jerky kuphoqa amasistimu e-clutch ukuthi asebenze njalo, okuholela ekugugeni ngokushesha kwezakhi zokungqubuzana.

Lapho ushayela esiminyaminyeni sezimoto edolobheni, udinga ukulandela imithetho embalwa:

• ungacindezeli igesi kanye nama-brake pedals ngenkathi ushayela u-0,5-1 m, kodwa vumela imoto engaphambili ihambe 5-6 m futhi ilandele ngesivinini esiphansi;
• shintshela kumodi ye-semi-automatic (manual) bese uhamba ngegiya lokuqala, ungavumeli okuzenzakalelayo ukuthi sebenze ngesimiso somnotho;
• ungafaki i-lever yokukhetha kumodi engathathi hlangothi, ngoba lapho i-pedal ye-brake icindezelekile, i-clutch ivuleka ngokuzenzakalelayo.

Sehlisa ijubane ngendlela efanele

Lapho usondela erobhothini noma ezimpambanweni zomgwaqo, abashayeli abaningi bakhetha ugu, okungukuthi, ukuvala igiya, ukushintshela kumodi engathathi hlangothi futhi baqhubeke nokuhamba ngenxa ye-inertia ezuziwe.

Ngokungafani namabhuleki enjini abushelelezi, ukuhamba ogwini akunciphisi nje kuphela ukusetshenziswa kukaphethiloli kuye ku-zero, kodwa futhi kwandisa ingozi yokuguga kokudlulisela. Uma ucindezela kakhulu i-pedal ye-brake endaweni yesikhethi N, khona-ke i-clutch ngeke ibe nesikhathi sokuvula nge-flywheel ngaphandle kokulimaza okokugcina.

Umthwalo omkhulu ku-gearbox uholela ekwakhekeni kwamaphuzu endaweni yokuxhumana ye-flywheel. Ngokuhamba kwesikhathi, ibhokisi liqala ukunyakaza lapho lishintsha isivinini, lidlidliza futhi lenza imisindo yokugaya.

I-pedal ye-brake kumele icindezeleke kahle, ivumele i-clutch ukuthi ivuleke ngokugcwele. Ukuma kungazelelwe kuvunyelwe kuphela ezimeni eziphuthumayo.

Ungaqala kanjani

Abashayeli abajwayele ukusheshisa ngokushesha bavame ukuphendukela ekucindezeleni kanyekanye igesi namabhuleki ama-pedal. I-automation ye "robot" isabela kulokhu ngokwandisa isivinini, ngakho-ke uma ususa unyawo lwakho ku-pedal ye-brake, isivinini sikhuphuka kakhulu.

Ama-jerk anjalo anciphisa kakhulu impilo ka-gearbox. Ukucindezela i-accelerator pedal kuvala ama-friction discs, kodwa ibhuleki elisetshenzisiwe livimbela imoto ukuthi inganyakazi. Ngenxa yalokho, i-slip yangaphakathi iyenzeka, okuholela ekugqokeni kwama-discs nokushisa ngokweqile kokudluliselwa.

Abanye abakhiqizi bahlomisa amabhokisi erobhothi ngokuvikela ngogesi. Uma ucindezela amaphedali angu-2, isistimu isabela ngokuyinhloko ebhulekini, ivule i-clutch ne-flywheel. Ijubane lenjini alinyuki, ngakho-ke ukusebenza kanyekanye kwebhuleki ne-accelerator akusho lutho.

Uma udinga ukuthatha ngokushesha isivinini ekuqaleni, vele ucindezele i-pedal yegesi. "Irobhothi" livumela izimo eziningi eziphuthumayo, ezihlanganisa ukuqala kungazelelwe. Isabelo sabo akufanele seqe ama-25% engqikithi.

Uma uqala ukukhuphuka, udinga ukusebenzisa ibhuleki lesandla. I-gas pedal icindezelwa kanyekanye nokususwa kwemoto kwi-handbrake ye-1-1,5 s. Ngaphandle kokuzinza kwesimo, umshini uzohlehla futhi ushelele.

Ukushintsha okungazelelwe kwejubane

Isitayela sokushayela esibikezelwayo nesicophelelayo sinweba impilo yebhokisi le-DSG. Ngokunyuka kwejubane okushelelayo, iyunithi yokudlulisela nge-elekthronikhi iyakwazi ukuhlanganisa igiya elifunekayo, ngokushintshana ibambe i-clutch yoku-1 neyesi-2.

Ukuqala okubukhali kanye nokubhuleka ngokushesha ngemva kokusheshisa kwenza i-mechatronics isebenze kumodi ephuthumayo. Ukushintsha ngokushesha kanye nokungqubuzana kubangela ukuqhuma kanye nokulimala kwediski. Ukudluliselwa okomile kuleli phuzu nakho kuhlushwa ukushisa ngokweqile.

Ukuze ungacasuli ukusebenza kwe-elekthronikhi okunezinxushunxushu, lapho ushayela ngesitayela esinolaka, kufanelekile ukuvula imodi yezandla. Ukusheshisa okusheshayo ngokushintsha okubukhali kwejubane akufanele kuthathe isikhathi esingaphezu kuka-20-25% wesikhathi sokushayela. Isibonelo, ngemuva kokusheshisa kwemizuzu emi-5, kufanele uvumele i-gearbox iphumule kwimodi ekhululekile imizuzu engu-15-20.

Emishinini enesisindo esincane nosayizi wenjini, efakwe amabhokisi "omile", kufanele ushiye ngokuphelele ukushayela ngokushintsha okubukhali kwejubane. Lezi zimoto zihlanganisa:

1. IVolkswagen Jetta, iGalofu 6 no-7, iPassat, iTouran, iScirocco.
2. I-Audi A1, A3, TT.
3. Seat Toledo, Altea, Leon.
4. Skoda Octavia, Superb, Fabia, Rapid, SE, Roomster, Yeti.

Ukudonsa nokushelela

Amarobhothi aphakeme kunama-othomathikhi ngokuya ngokuzwela kokushelela. Ayigcini ngokusheshisa ukuguga kwengxenye yemishini yokudlulisela, kodwa futhi iphazamisa iyunithi ye-elekthronikhi.

Ukuze ugweme ukushelela, izincomo ezilandelayo kufanele zibhekwe:

• faka amathayi amahle afakwe ebusika;
• uma kunezimvula njalo nangenkathi ebandayo, hlola izindawo zokuphuma egcekeni kusengaphambili ukuze zijule ngokungcola noma izindawo ezinkulu zeqhwa;
• phusha izimoto ezibhajwe ngesandla kuphela, ngaphandle kokucindezela i-gas pedal (imodi engu-N);
• ezindaweni ezinzima zomgwaqo, qala ukuhamba ngemodi yezandla ngegiya lesi-2, ugweme ukuqala okungazelelwe nge-accelerator pedal.

Uma ugibela endaweni eshelelayo, udinga ukuvula imodi ye-M1 bese ucindezela i-pedal yegesi kancane ukuze uvimbele ukushelela.

Ukudonsa enye imoto noma i-trailer esindayo kudala umthwalo omkhulu ku-gearbox, ngakho-ke kuhle ukuwenqaba ngohlobo olomile lokudlulisela.

Uma imoto ene-DSG-7 ayikwazi ukuhamba yodwa, khona-ke umshayeli kufanele abize iloli lokudonsa. Ezimeni lapho ukudonsa kungenakugwenywa, kufanele kwenziwe ngenjini egijima futhi idluliselwe ngokungathathi hlangothi. Ibanga elihanjwa yimoto akumele lidlule ku-50 km, futhi ijubane akufanele lidlule ku-40-50 km/h. Imininingwane eqondile yemodeli ngayinye ikhonjisiwe encwadini yeziqondiso.

Ukushintsha amamodi

I-mechatronic ayikubekezeleli ukungenelela okuvamile emsebenzini wayo, ngakho-ke imodi yezandla (M) kufanele isetshenziswe kuphela ezimweni ezingavamile kuma-electronics. Lokhu kuhlanganisa ukuqala emgwaqeni onzima, ukushayela esiminyaminyeni sezimoto, ukushintsha isivinini ngokushesha, nokushayela ngamandla ngokusheshisa nokuhlehla njalo.

Uma usebenzisa imodi yezandla, unganciphisi isivinini ngaphambi kokuyehlisa, futhi usinyuse uma sikhuphuka. Udinga ukushintsha phakathi kwamamodi ngokushelela, ngokulibaziseka kwemizuzwana engu-1-2.

Sipaka

Imodi yokupaka (P) ingenziwa isebenze kuphela ngemva kokuma. Ngaphandle kokukhulula i-pedal ye-brake, kuyadingeka ukusebenzisa i-handbrake: lokhu kuzovimbela ukulimala kumkhawulo lapho uhlehla.

Isisindo semoto kanye ne-DSG

Impilo ye-DSG-7, ikakhulukazi uhlobo olomile, ihlotshaniswa ngokuphambene nesisindo semoto. Uma isisindo semoto esinabagibeli sisondela kumathani ama-2, khona-ke ukuwohloka kwenzeka kaningi ekudlulisweni okuzwela ukugcwala ngokweqile.

Ngomthamo wenjini ongaphezu kwamalitha angu-1,8 nesisindo semoto esingamathani angu-2, abakhiqizi bakhetha uhlobo lwe-clutch "elimanzi" noma i-gearbox engu-6-speed (DSG-6) ehlala isikhathi eside.

Ukunakekelwa kwemoto nge-DSG-7

Isheduli yokulungisa yohlobo lwe-DSG-7 "dry" (DQ200) ayifaki ukugcwaliswa kwamafutha. Ngokwencazelo yomkhiqizi, izithambisi ezisebenza nge-hydraulic kanye ne-transmission zigcwaliswa impilo yonke yesevisi. Kodwa-ke, oomakhenikha bezimoto batusa ukuthi kubhekwe isimo sebhokisi ekulungiseni ngakunye bese wengeza uwoyela uma kunesidingo ukuze kwandiswe impilo yebhokisi likagiya.

"Wet" clutch kudinga refueling ngamafutha njalo amakhilomitha ayizinkulungwane 50-60. Uwoyela weHydraulic uthululelwa ku-mechatronics, i-G052 noma i-G055 uwoyela wochungechunge engxenyeni yebhokisi, kuya ngohlobo lomshini. Kanye ne-lubricant, isihlungi se-gearbox siyashintshwa.

Kanye njalo ukulungiswa okungu-1-2, i-DSG kufanele iqaliswe. Lokhu kukuvumela ukuthi ulinganise ukusebenza kwe-elekthronikhi futhi ususe ama-jerks lapho ushintsha isivinini. Iyunithi ye-elekthronikhi ayivikelekile kahle ekungeneni komswakama, ngakho-ke udinga ukuyigeza ngokucophelela ngaphansi kwe-hood.
