Yuav ua li cas kom raug Dsg 7
Txheem
DSG (los ntawm kev hloov ncaj qha gearbox - "direct gearbox") yog ib lub tshuab hluav taws xob uas muaj 2 clutches thiab tswj los ntawm lub tshuab hluav taws xob (mechatronics). Qhov zoo ntawm qhov kis tau tus mob no yog lub zog hloov pauv ceev vim yog kev sib koom ua ke ntawm cov clutches, muaj peev xwm ntawm kev tswj kev tswj thiab roj kev lag luam, thaum qhov tsis zoo yog lub neej kev pabcuam luv luv, kho cov nqi, overheating nyob rau hauv load thiab kis ntawm sensors.
Kev ua haujlwm kom zoo ntawm 7-ceev DSG lub thawv tso cai rau koj kom ntev lub neej ntawm lub gearbox thiab txo qhov kev pheej hmoo ntawm kev tawg vim yog hnav ntawm bearings, bushings thiab lwm yam kev sib txhuam.
Cov cai rau kev tsav tsheb DSG-7
Cov clutches ntawm lub thawv neeg hlau tsis rov ua dua. Qhov thib 1 yog lub luag haujlwm rau kev suav nrog lub zog tsis sib xws, thiab thib 2 - ua khub. Cov txheej txheem tig rau ib txhij, tab sis kev sib cuag nrog lub ntsiab disk tsuas yog thaum lub hom sib txuas tau qhib. Qhov thib 2 txheej ua kom txav nrawm dua.
DSG-7 clutches tuaj yeem "qhuav" thiab "ntub". Thawj qhov ua haujlwm ntawm kev sib txhuam tsis muaj roj txias. Qhov no txo cov roj noj los ntawm 4,5-5 zaug, tab sis txo qhov siab tshaj plaws ntawm lub cav ceev thiab ua rau muaj kev pheej hmoo ntawm gearbox puas vim hnav.
"Dry" DSGs tau nruab rau ntawm lub tsheb me me nrog lub cev muaj zog qis. Txawm hais tias lawv tau tsim los rau kev tsav tsheb hauv nroog, qee qhov kev tsav tsheb (kev tsheb thauj mus los, kev hloov pauv, kev thauj mus los) tuaj yeem ua rau muaj cua sov.
"Ntev" DSG-7s tuaj yeem tiv taus cov khoom hnyav: lub zog nrog kev sib kis tau mus txog 350-600 Nm, thaum "qhuav" tuaj yeem tsis ntau tshaj 250 Nm. Vim yog cov roj hydraulic txias, nws tuaj yeem ua haujlwm hauv hom hnyav dua.
Tsiv kom raug nyob rau hauv lub nroog tsheb jams
Thaum tsav tsheb, DSG tau hloov mus rau lub iav siab dua. Thaum tsav tsheb, qhov no tuaj yeem txo qis kev siv roj ntau, tab sis nrog kev nres ntau zaus hauv kev sib tsoo, nws tsuas yog hnav tawm qhov sib kis.
Raws li qhov xwm ntawm lub gearbox, qhov kev hloov no koom nrog ob lub clutches. Yog tias tus neeg tsav tsheb tsis nrawm mus rau qhov xav tau ceev lossis nias lub nres thaum txav mus rau hauv cov tsheb khiav ceev, tom qab thawj qhov kev hloov pauv yuav rov qab mus rau qhov qis tshaj, thawj lub iav.
Jerky tsav yuam lub clutch systems ua haujlwm tas li, uas ua rau muaj kev sib txhuam ceev ceev.
Thaum tsav tsheb nyob rau hauv lub nroog tsheb jam, koj yuav tsum ua raws li ob peb txoj cai:
- tsis txhob nias lub roj thiab nres pedals cyclically thaum tsav tsheb 0,5-1 m, tab sis cia lub tsheb nyob rau hauv pem hauv ntej mus rau 5-6 m thiab ua raws li ntawm tsawg ceev;
- hloov mus rau semi-automatic (phau ntawv) hom thiab txav mus rau hauv thawj iav, tsis pub lub automation ua raws li txoj cai ntawm kev lag luam;
- Tsis txhob muab lub selector lever nyob rau hauv nruab nrab hom, vim hais tias thaum lub nres pedal yog kev nyuaj siab, lub clutch qhib tau.
Peb qeeb kom raug
Thaum mus txog lub teeb pom kev los yog kev sib tshuam, ntau tus neeg tsav tsheb nyiam mus rau ntug dej hiav txwv, piv txwv li, tua lub iav, hloov mus rau hom nruab nrab thiab txuas ntxiv mus vim qhov tau txais inertia.
Tsis zoo li kev sib tsoo lub cav, cov ntug dej hiav txwv tsis tsuas yog txo cov roj noj mus rau xoom, tab sis kuj ua rau muaj kev pheej hmoo ntawm kev sib kis. Yog tias koj ua rau tus nres nres nres hauv qhov chaw xaiv N, ces lub clutch yuav tsis muaj sijhawm qhib nrog lub flywheel yam tsis muaj kev puas tsuaj tom kawg.
Lub siab load ntawm lub gearbox ua rau tsim cov qhab nia ntawm qhov chaw sib cuag ntawm flywheel. Thaum lub sij hawm, lub thawv pib twitch thaum hloov ceev, vibrate thiab ua suab sib tsoo.
Lub nres pedal yuav tsum muaj kev nyuaj siab zoo, cia lub clutch qhib tag nrho. Sudden nres tsuas yog tso cai thaum muaj xwm txheej ceev.
Yuav pib li cas
Cov neeg tsav tsheb accustomed mus ceev acceleration feem ntau mus rau ib txhij nias lub roj thiab nres pedals. Lub automation ntawm "neeg hlau" reacts rau qhov no los ntawm kev ua kom ceev, yog li thaum koj tshem koj txhais taw ntawm tus nres pedal, qhov ceev nce sharply.
Xws li jerks drastically txo lub neej ntawm lub gearbox. Nias lub accelerator pedal kaw cov kev sib txhuam discs, tab sis tus brake thov txwv tsis pub lub tsheb txav. Raws li qhov tshwm sim, kev poob hauv qhov tshwm sim, uas ua rau hnav ntawm cov discs thiab overheating ntawm kev sib kis.
Qee cov tuam txhab tsim cov thawv neeg hlau nrog kev tiv thaiv hluav taws xob. Thaum koj nias 2 pedals, lub kaw lus reacts feem ntau rau lub nres, qhib lub clutch thiab flywheel. Lub cav ceev tsis nce, yog li kev ua kom ib txhij ntawm tus nres thiab accelerator tsis muaj nuj nqis.
Yog tias koj xav tau ceev ceev ceev thaum pib, tsuas yog nyem lub roj pedal. "Robot" tso cai rau ntau qhov xwm txheej ceev, uas suav nrog kev pib sai sai. Lawv feem yuav tsum tsis pub tshaj 25% ntawm tag nrho.
Thaum pib nce toj, koj yuav tsum siv lub tes tuav. Cov roj pedal yog nias ib txhij nrog kev tshem tawm ntawm lub tsheb los ntawm tus brake rau 1-1,5 s. Yog tsis muaj kev ruaj ntseg ntawm txoj hauj lwm, lub tshuab yuav yob rov qab thiab plam.
Sudden hloov nyob rau hauv ceev
Qhov kev xav tau thiab ceev faj tsav tsheb txuas ntxiv lub neej ntawm DSG lub thawv. Nrog rau kev nce nrawm nrawm, lub tshuab hluav taws xob kis tau tus mob tswj kom koom nrog cov iav uas xav tau, sib txuas nrog 1st thiab 2nd clutches.
Kev pib ntse thiab braking tam sim ntawd tom qab acceleration ua rau cov mechatronics ua haujlwm nyob rau hauv hom xwm txheej ceev. Kev hloov ceev ceev thiab kev sib txhuam ua rau scuffing thiab kev puas tsuaj rau lub disc. Qhuav kis ntawm qhov chaw no kuj raug kev txom nyem los ntawm overheating.
Txhawm rau kom tsis txhob ua rau muaj kev ntxhov siab ntawm kev ua haujlwm ntawm cov khoom siv hluav taws xob, thaum tsav tsheb hauv qhov kev nruj nruj, nws tsim nyog tig rau ntawm phau ntawv hom. Kev nrawm nrawm nrog kev hloov pauv nrawm yuav tsum tsis pub ntau tshaj 20-25% ntawm lub sijhawm tsav tsheb. Piv txwv li, tom qab 5 feeb acceleration, koj yuav tsum cia lub gearbox so nyob rau hauv ib tug xis hom rau 15-20 feeb.
Ntawm cov cav tov nrog ib tug me me loj thiab lub cav loj, uas yog txawm peem rau nrog "qhuav" thawv, koj yuav tsum kiag li tso tseg tsav tsheb nrog ib tug ntse hloov nyob rau hauv ceev. Cov tsheb no suav nrog:
- Volkswagen Jetta, Golf 6 thiab 7, Passat, Touran, Scirocco.
- Audi A1, A3, TTJ.
- Seat Toledo, Altea, Leon.
- Skoda Octavia, Superb, Fabia, Rapid, SE, Roomster, Yeti.
Towing thiab swb
Robotic transmissions yog superior rau tsis siv neeg kis tau tus mob nyob rau hauv cov nqe lus ntawm plam rhiab heev. Nws provokes tsis tsuas yog accelerated hnav ntawm txhua yam ntawm cov kis tau tus mob, tab sis kuj destabilizes lub electronics unit.
Txhawm rau kom tsis txhob swb, cov lus pom zoo hauv qab no yuav tsum tau ua raws:
- muab cov log tsheb zoo rau lub caij ntuj no;
- nyob rau hauv cov ntaub ntawv uas nquag los nag thiab nyob rau hauv lub caij txias, tshuaj xyuas cov tawm ntawm lub vaj ua ntej kom tob nrog av los yog loj cheeb tsam ntawm dej khov;
- thawb lub tsheb nkaus xwb manually, tsis nias lub roj pedal (N hom);
- ntawm txoj kev nyuaj, pib txav mus rau hauv phau ntawv hom nyob rau hauv 2nd iav, tsis txhob cia li pib nrog accelerator pedal.
Thaum nce saum npoo av, koj yuav tsum tau qhib M1 hom thiab nias lub roj pedal tsawg kawg nkaus kom tsis txhob ntog.
Towing lwm lub tsheb los yog lub tsheb hnyav hnyav ua rau muaj kev thauj khoom ntau dhau ntawm lub gearbox, yog li nws raug nquahu kom tsis kam lees nws nrog hom qhuav ntawm kev sib kis.
Yog tias lub tsheb nrog DSG-7 tsis tuaj yeem txav ntawm nws tus kheej, tus neeg tsav tsheb yuav tsum hu rau lub tsheb thauj khoom. Nyob rau hauv rooj plaub uas towing tsis tuaj yeem zam tau, nws yuav tsum tau ua nrog lub cav khiav thiab kev sib kis hauv nruab nrab. Qhov kev ncua deb ntawm lub tsheb yuav tsum tsis txhob tshaj 50 km, thiab qhov ceev yuav tsum tsis txhob tshaj 40-50 km / h. Cov ntaub ntawv tseeb rau txhua tus qauv yog qhia hauv phau ntawv qhia.
Hloov hom
Lub mechatronic tsis zam kev cuam tshuam ntau zaus hauv nws txoj haujlwm, yog li phau ntawv hom (M) yuav tsum tsuas yog siv rau hauv cov xwm txheej uas txawv ntawm cov khoom siv hluav taws xob. Cov no suav nrog kev pib ntawm txoj kev nyuaj, tsav tsheb hauv tsheb, hloov nrawm nrawm, thiab tsav tsheb hnyav nrog kev nrawm nrawm thiab nrawm.
Thaum siv phau ntawv hom, tsis txhob txo qhov ceev ua ntej downshifting, thiab kuj nce nws thaum nws yog upshifting. Koj yuav tsum tau hloov ntawm cov hom kom du, nrog ncua sijhawm ntawm 1-2 vib nas this.
Peb nres
Chaw nres tsheb hom (P) tsuas yog qhib tau tom qab nres. Yog tias tsis tso tus brake pedal, nws yog ib qho tsim nyog yuav tsum tau siv lub brake: qhov no yuav tiv thaiv kev puas tsuaj rau lub limiter thaum dov rov qab.
Tsheb hnyav thiab DSG
Lub neej ntawm DSG-7, tshwj xeeb tshaj yog hom qhuav, yog inversely correlated nrog lub tsheb hnyav. Yog hais tias qhov loj ntawm lub tsheb nrog cov neeg caij tsheb mus txog 2 tons, ces kev puas tsuaj tshwm sim ntau dua nyob rau hauv cov kis tau tus mob rhiab heev rau overload.
Nrog lub cav muaj peev xwm ntau dua 1,8 litres thiab lub tsheb hnyav ntawm 2 tons, cov neeg tsim khoom nyiam "ntub" hom clutch lossis ntau dua 6-ceev gearbox (DSG-6).
Kev kho tsheb nrog DSG-7
Lub sijhawm saib xyuas rau DSG-7 "qhuav" hom (DQ200) tsis suav nrog roj filling. Raws li cov chaw tsim khoom piav qhia, hydraulic thiab kis tau tus mob lubricants tau ntim rau tag nrho cov kev pabcuam lub neej. Txawm li cas los xij, auto mechanics pom zoo kom kuaj xyuas qhov xwm txheej ntawm lub thawv ntawm txhua qhov kev saib xyuas thiab ntxiv roj yog tias tsim nyog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws
"Dawb" clutch yuav tsum tau refueling nrog roj txhua txhua 50-60 txhiab kilometers. Hydraulic roj yog nchuav rau hauv mechatronics, G052 lossis G055 series roj rau hauv cov khoom siv ntawm lub thawv, nyob ntawm seb hom mechanism. Ua ke nrog cov roj nplua nyeem, lub tshuab lim gearbox hloov.
Ib zaug txhua 1-2 txij nkawm, DSG yuav tsum pib. Qhov no tso cai rau koj los ntsuas kev ua haujlwm ntawm cov khoom siv hluav taws xob thiab tshem tawm cov jerks thaum hloov ceev. Lub tshuab hluav taws xob tsis zoo tiv thaiv los ntawm kev nkag mus ntawm cov dej noo, yog li koj yuav tsum tau ntxuav nws kom zoo hauv qab lub hood.
