DSG gearbox - ndichiyani? Umboni ndi mavidiyo

Tapereka kale chidwi kwambiri pa portal yathu kumitundu yosiyanasiyana yamagalimoto. Eni Volkswagen, Skoda, Mpando magalimoto mu kufotokoza luso magalimoto awo mu ndime kufala kuona chidule DSG. Kodi zilembo zachilatini izi zimatanthauza chiyani? Tiyeni tiyese kuzilingalira.

Kutumiza kwa robotic kumasiyana ndi makina wamba komanso kuchokera kumayendedwe odziwikiratu ndi kukhalapo kwa ma clutch awiri. Chifukwa cha kapangidwe kameneka, kusinthasintha kosalala kwamagawo othamanga popanda ma jerks ndi kuchedwa kumatsimikizika. Chabwino, ndi robotic chifukwa gawo lamagetsi lamagetsi limayang'anira kusuntha magiya, motero, dalaivala ali ndi mwayi wosinthira ku zowongolera zokha komanso pamanja.

M'mawu osavuta, kufala kwa DSG ndi njira yosakanizira yopambana yapamanja komanso yodziwikiratu. Komabe, kusiyana kwake kwakukulu ndi kuphatikizika kawiri.

Chida cha bokosicho ndi motere:

• wapawiri-wambiri crankshaft flywheel - amapereka yunifolomu kufala kwa makokedwe kwa onse clutch zimbale, tichipeza pulayimale ndi sekondale zimbale, pamene flywheel ochiritsira ali ndi dongosolo monolithic;
• ma clutch discs awiri - magiya osakanikirana ndi osamvetseka;
• mitsinje iwiri ya pulayimale ndi yachiwiri pa clutch iliyonse;
• zida zazikulu za cylindrical (zagalimoto zoyendetsa kutsogolo);
• kusiyana (kwa magalimoto oyendetsa kutsogolo).

Ngati muli ndi galimoto yoyendetsa kumbuyo ndi kufala kwa DSG, ndiye kuti giya lalikulu ndi zosiyana zili m'nyumba yaikulu, ngakhale kuti zimagwirizanitsidwa ndi bokosi la gear ndikugawa torque mofanana ndi mawilo oyendetsa.

Chipangizochi chimadaliranso kuchuluka kwa magiya. Chifukwa chake, pagalimoto yokhala ndi 6-speed DSG gearbox, clutch ndi yamtundu "yonyowa", ndiye kuti, ma clutch discs ali mubokosi lamafuta, zomwe zimachepetsa kukangana. Pa ma gearbox 7-liwiro, clutch ndi mtundu "wouma". Imavala mwachangu, komabe, mwanjira iyi ndizotheka kupeza ndalama zambiri pamafuta amafuta a ATF: koyamba, pamafunika pafupifupi malita 6-7, ndipo chachiwiri - osapitilira awiri.

Mfundo ya ntchito ya robotic gearbox

Mfundo yake ndi yosavuta. Chifukwa chake, pamakina wamba, dalaivala amayenera kusintha motsatizana kuchokera pa liwiro lina kupita ku lina posintha lever ya gearshift. Pa "roboti" DSG magiya awiri nthawi imodzi amachita - m'munsi ndi apamwamba. Yam'munsi ikugwira ntchito, ndipo yachiwiri ikugwira ntchito. Ndi liwiro lowonjezereka, kusintha kumachitika mu magawo khumi a sekondi.

Ngati mwafika pa liwiro lalikulu, ndiye kuti giya yotsika imagwira ntchito mopanda pake. ECU imayang'anira zonse izi. Masensa osiyanasiyana amasanthula liwiro la crankshaft, malo opumira komanso malo opondapo gasi. Chidziwitso chimalowa mugawo lowongolera ndipo chisankho chimapangidwa kuti chisinthe zida. Ma pulses amatumizidwa ku hydraulic actuators (ma valve solenoid, hydraulic circuit) ndipo njira yabwino kwambiri yothamanga imasankhidwa pagawo linalake la msewu.

Ubwino ndi kuipa kwa DSG

Tsoka ilo, timakakamizika kunena kuti, ngakhale ali ndi luso, ma gearbox a robotic a disk-disk ali ndi zovuta zambiri:

• mtengo wokwera wa utumiki;
• kuvala mofulumira kwa ziwalo zopaka (makamaka ndi clutch youma);
• oyendetsa galimoto amadziwa kwambiri za mavutowa, choncho zingakhale zovuta kwambiri kugulitsa galimoto yogwiritsidwa ntchito.

Ngakhale chitsimikizo ndi chovomerezeka, zovuta sizimawonekera. Monga lamulo, ndi ma clutch discs omwe amalephera mwachangu kwambiri. Samalani mfundo iyi: ngati pa DSG-6 (youma mtundu) chimbale akhoza kungosintha kusintha, ndiye pa DSG-7 muyenera kukhazikitsa kwathunthu zowalamulira, amene ndalama pafupifupi ngati gearbox latsopano.

Chigawo chamagetsi chokha ndi ma actuators nawonso ndi osalimba. Akatenthedwa kwambiri, masensa amatha kupereka chidziwitso cholakwika kwa ECU, zomwe zimapangitsa kuti pakhale kusagwirizana pakuwongolera komanso ma jerks akuthwa amamveka.

Njira yosavuta yofulumira "kupha" bokosi la gear loboti ndikuyika galimoto pamagetsi kapena m'misewu yapamsewu ndi brake pedal, osati kusinthana ndi ndale.

Komabe, ma gearbox oterowo akupitiliza kupangidwa, chifukwa ali ndi zabwino zambiri:

• kugwiritsa ntchito mafuta ochulukirapo - kupulumutsa mpaka 10%;
• kuchepetsa utsi wowononga chilengedwe;
• kwambiri mathamangitsidwe mphamvu;
• kukwera chitonthozo, kumasuka ntchito.

Moyo wautumiki umafika pafupifupi makilomita 150 zikwi.

Kutengera zomwe tafotokozazi, akonzi a Vodi.su amalimbikitsa kuti mutenge njira yodalirika posankha galimoto yogwiritsidwa ntchito ndi DSG. Ngati munagula galimoto yatsopano, tsatirani malangizo a wopanga kuti musawononge ndalama zokonzanso ndalama.

DSG bokosi ndi mavuto ake
