DSG gearbox - kuyini? Ubufakazi namavidiyo
Sesivele sinake kakhulu ingosi yethu ezinhlotsheni ezahlukene zokuhanjiswa kwezimoto. Abanikazi bezimoto zeVolkswagen, Skoda, Seat encazelweni yobuchwepheshe yezimoto zabo kukholamu yokudlulisa bangabona isifinyezo esithi DSG. Zisho ukuthini lezi zinhlamvu zesiLatini? Ake sizame ukukuqonda.
I-robotic transmission ihlukile komakhenikha abavamile kanye nokudlulisa okuzenzakalelayo ngokuba khona kwe-double clutch. Ngenxa yalesi sici sokuklama, ukushintshwa okushelelayo kwebanga lesivinini ngaphandle kwama-jerks nokubambezeleka kuyaqinisekiswa. Hhayi-ke, i-robotic ngoba iyunithi yokulawula i-elekthronikhi inesibopho sokushintsha amagiya, ngokulandelana, umshayeli unethuba lokushintshela kukho kokubili othomathikhi kanye nokulawula okwenziwa ngesandla.
Ngamagama alula, i-DSG transmission iyinhlanganisela eyimpumelelo yama-manual kanye nama-automatic transmissions. Kodwa noma kunjalo, umehluko wawo omkhulu yi-double clutch.
Idivayisi yebhokisi imi kanje:
- I-crankshaft flywheel ene-dual-massive - inikeza ukudluliswa okufanayo kwe-torque kuwo womabili ama-clutch discs, aqukethe ama-disc ayisisekelo nawesibili, kuyilapho i-flywheel evamile inesakhiwo se-monolithic;
- ama-clutch discs amabili - amagiya alinganayo futhi angajwayelekile;
- ama-shafts amabili ayisisekelo kanye nesesibili ku-clutch ngayinye;
- cylindrical main gear (ezimotweni ezine-front-wheel drive);
- umehluko (kwezimoto ezihamba ngamasondo angaphambili).
Uma unemoto edonsa ngamasondo angemuva ene-DSG, khona-ke igiya eliyinhloko nokuhluka kutholakala ku-axle yezindlu ezinkulu, nakuba zixhunywe ngokuhlelekile nebhokisi le-gearbox futhi zisakaza i-torque ngokulinganayo kumasondo okushayela.
Idivayisi nayo incike kakhulu enanini lamagiya. Ngakho-ke, emotweni ene-gearbox ye-DSG engu-6-speed, i-clutch iwuhlobo "olumanzi", okungukuthi, ama-clutch discs asebhokisini likawoyela, elinciphisa ukungqubuzana. Kuma-gearbox angu-7-speed, i-clutch iwuhlobo "omile". Kungaphansi kokugqoka okusheshayo, noma kunjalo, ngale ndlela kungenzeka ukuthola ukonga okubalulekile kuwoyela wegiya le-ATF: esimweni sokuqala, kudinga cishe amalitha angama-6-7, kanti okwesibili - akukho ngaphezu kwamabili.
Umgomo wokusebenza kwebhokisi lamagiya erobhothi
Isimiso silula. Ngakho-ke, kumakhenikha ajwayelekile, umshayeli kufanele ashintshe ngokulandelana ukusuka kwesinye isivinini ukuya kwesinye ngokushintsha i-lever yegiya. Ku-"robot" DSG, amagiya amabili ahlangene ngesikhathi esisodwa - aphansi nangaphezulu. Ophansi uyasebenza, owesibili uyavilapha. Ngokukhula kwesivinini, ukushintsha kwenzeka engxenyeni yeshumi yomzuzwana.
Uma usufinyelele isivinini esiphezulu, igiya eliphansi lisebenza kumodi engenzi lutho. I-ECU iqapha yonke le nqubo. Izinzwa ezahlukahlukene zihlaziya isivinini se-crankshaft, indawo yokudonsa kanye nendawo yokunyathela igesi. Ulwazi lungena endaweni yokulawula bese kuthathwa isinqumo sokushintsha igiya. Ama-pulses athunyelwa kuma-actuator we-hydraulic (ama-solenoid valve, i-hydraulic circuit) futhi imodi yesivinini esiphezulu ikhethwa engxenyeni ethile yomgwaqo.
Izinzuzo kanye nokubi kwe-DSG
Ngeshwa, siphoqeleka ukusho iqiniso lokuthi, naphezu kokusungula kwabo okusha, ama-gearbox we-robotic ama-double-disk anemibi eminingi:
- izindleko eziphezulu zesevisi;
- ukugqoka okusheshayo kwezingxenye zokuxubha (ikakhulukazi nge-clutch eyomile);
- abashayeli bezimoto bazazi kahle lezi zinkinga, ngakho kungaba nzima kakhulu ukudayisa imoto esetshenzisiwe.
Ngenkathi iwaranti isebenza, izinkinga azibonakali. Njengomthetho, ama-clutch discs ahluleka ngokushesha kakhulu. Naka leli qiniso: uma ku-DSG-6 (uhlobo olomile) i-disc ingashintshwa kalula, khona-ke ku-DSG-7 kufanele ufake ngokuphelele i-clutch entsha, ebiza cishe njenge-gearbox entsha.
Iyunithi ye-elekthronikhi ngokwayo kanye nama-actuator nakho kuthambile kakhulu. Uma kushisa kakhulu, izinzwa zinganikeza ulwazi olungalungile ku-ECU, okuholela ekungavumelani kokulawula kanye nama-jerks abukhali azwakala.
Indlela elula "yokubulala" ngokushesha i-gearbox yerobhothi ukugcina imoto emarobhothini noma esiminyaminyeni sezimoto nge-brake pedal, hhayi ngokushintshela kokungathathi hlangothi.
Noma kunjalo, ama-gearbox anjalo ayaqhubeka nokukhiqizwa, ngoba anezinzuzo eziningi:
- ukusetshenziswa kukaphethiloli ukonga okwengeziwe - ukonga kufikela ku-10%;
- ukunciphisa ukukhishwa kwegesi eyingozi endaweni ezungezile;
- ama-dynamics asheshayo amahle kakhulu;
- ukugibela ukunethezeka, ukusebenza kalula.
Impilo yesevisi ifinyelela isilinganiso samakhilomitha ayizinkulungwane eziyi-150.
Ngokusekelwe kulokhu osekushiwo ngaphambili, abahleli be-Vodi.su batusa ukuthi uthathe indlela enesibopho sokukhetha imoto esetshenzisiwe nge-DSG. Uma uthenge imoto entsha, landela imiyalelo yomkhiqizi ukuze ungangeni ezindlekweni zokulungisa izimali.
Iyalayisha...
