Yog li, cov classic "mechanical" clutch feem ntau koom nrog, uas yog, cov tsav tsheb thiab tsav tsheb raug kaw thaum lub pedal tso tawm. Hauv ib lub thawv neeg hlau, lub clutch feem ntau qhib. Torque kis tau tus mob yog muab los ntawm mechatronics los ntawm clamping lub clutch raws li dab tsi torque yuav tsum tau xa mus rau lub thawv. Qhov ntau lub roj pedal yog kev nyuaj siab, ntau lub clutch yog clamped. Raws li, rau kev kuaj mob lub xeev ntawm ib tug neeg hlau clutch, tsis tsuas yog txhua yam, tab sis kuj thermal yam ntxwv tseem ceeb. Thiab nws yog ntshaw kom tua lawv nyob rau hauv dynamics, uas yog, thaum lub tsheb tsiv.

Mechanics check

Tom qab txuas lub laptop mus rau ECU thiab pib Vasya Diagnostic program, koj yuav tsum mus rau thaiv 2 hu ua "Transmission Electronics". ntxiv - "Block of Measures". Ua ntej koj yuav tsum kuaj xyuas tus mob ntawm thawj disk, cov no yog pab pawg 95, 96, 97. Siv cov kev pab cuam, koj tuaj yeem tsim ib daim duab, tab sis koj tsis tuaj yeem ua qhov no. uas yog, koj yuav tsum tau them sai sai rau qhov txwv tus nqi ntawm tus mob stroke thiab tam sim no (kuaj) txwv txoj hauj lwm ntawm tus pas nrig. Tshem tawm ntawm ib leeg. Qhov sib txawv tshwm sim yog disc stroke cia nyob rau hauv millimeters thickness. Ib txoj kev zoo sib xws yuav tsum tau ua rau lub disk thib ob. Txhawm rau ua qhov no, mus rau pawg 115, 116, 117. Feem ntau, ntawm lub clutch tshiab, cov npoo sib thooj yog nyob rau thaj tsam ntawm 5 txog 6,5 hli. Qhov me me, qhov ntau disk hnav.

Thov nco ntsoov tias qhov seem ntawm thawj DSG clutch disc yuav tsum tsis pub tsawg tshaj 2 hli, thiab thib ob disk - qis 1mm!!!

Nws yog ntshaw kom ua cov txheej txheem zoo sib xws nyob rau hauv dynamics, uas yog, thaum lub tsheb yog tsiv raws tus du, txawm txoj kev nrog siab tshaj plaws torque kis tau tus mob mus rau lub thawv. Txhawm rau ua qhov no, mus rau pawg 91 thiab 111 rau thawj thiab thib ob disk, feem. Koj tuaj yeem tsav kev kuaj mob hauv D hom lossis hauv plaub, tsib lossis rau lub zog. Dynamics yuav tsum tau ntsuas ntawm qhov sib npaug thiab khib clutch. Nws raug nquahu kom nias lub pob Graph ua ntej kom qhov kev zov me nyuam rub cov duab tsim nyog.

Raws li cov txiaj ntsig graphs, ib tus tuaj yeem txiav txim siab tus nqi ntawm qhov tso zis ntawm lub pas nrig ua haujlwm. Nws yog ib qho tseem ceeb uas yuav tsum tau them sai sai rau qhov siab tshaj plaws tso zis tawm. Thiab qhov ntxiv tus nqi tau txais los ntawm qhov txwv, qhov zoo dua (tsis hnav tawm) mob lub clutch discs yog.

Txheeb xyuas qhov ntsuas kub

Tom ntej no koj yuav tsum mus rau qhov kub thiab txias yam ntxwv. Ua ntej koj yuav tsum tau saib cov ntsuas static. Ua li no, mus rau pawg 99, 102 rau thawj disk thiab 119, 122 rau qhov thib ob. Los ntawm kev nyeem ntawv, koj tuaj yeem paub seb lub clutch ua haujlwm hauv hom tseem ceeb, thiab yog tias muaj, pes tsawg teev raws nraim. Koj tuaj yeem saib qhov ntsuas kub tshwj xeeb ntawm qhov screen. Qhov qis dua qhov kub ntawm lub clutch ua haujlwm, qhov zoo dua, nws hnav tsawg dua.

Tom qab ntawd, koj yuav tsum mus rau pawg naj npawb 98 thiab 118 rau thawj thiab thib ob disks, raws li. Ntawm no koj tuaj yeem pom tus nqi ntawm coefficient ntawm adhesion, deformation ntawm lub clutch, nrog rau qhov siab tshaj plaws ua haujlwm kub. Qhov zoo ntawm adhesion coefficient yuav tsum yog 0,95-1,00 Nws. Qhov no qhia tau hais tias lub clutch xyaum tsis plam. Yog hais tias qhov sib thooj coefficient qis dua, thiab tseem ceeb dua, qhov no qhia tias hnav clutch. Tus nqi qis dua, qhov phem dua.

.

Thov nco ntsoov tias qee zaum lub cuab yeej yuav qhia tus nqi ntau dua ib qho! Qhov no yog vim qhov peculiarities ntawm kev ntsuas tsis ncaj thiab yuav tsum tsis txhob ua rau muaj kev txhawj xeeb, tus nqi yuav tsum tau coj los ua ib qho.

Lub hom phiaj tseem ceeb kuj ntsuas indirectly. Qhov zoo tshaj plaws, nws yuav tsum yog xoom. Qhov ntau dua qhov sib txawv ntawm xoom, qhov phem dua. Kab kawg ntawm lub vijtsam hauv hom no yog qhov siab tshaj plaws disc kub rau tag nrho lub sijhawm ua haujlwm ntawm lub clutch. Qhov qis dua, qhov zoo dua.

Tom ntej no, koj yuav tsum sau cov ntaub ntawv hais txog qhov kub thiab txias ntawm cov disks hauv dynamics. Txhawm rau ua qhov no, koj yuav tsum mus rau pawg 126 hauv qhov program, qhov program kos ib daim duab nrog ob kab. Ib qho (daj los ntawm lub neej ntawd) yog thawj disk, uas yog, khib zog, qhov thib ob (lub teeb xiav los ntawm lub neej ntawd) yog qhov thib ob, txawm tias lub zog. Qhov kev txiav txim siab dav dav ntawm kev sim qhia tau hais tias qhov siab dua lub cav ceev thiab lub nra ntawm lub clutch, qhov kub ntawm cov discs ntau dua. Raws li, nws yog ntshaw kom tus nqi kub ntawm qhov tsawg li tsawg tau.

Thov nco ntsoov tias qee qhov kev pabcuam tsheb muab rau lawv cov neeg siv khoom, nrog kev pab ntawm kev hloov kho software, kom tshem tawm kev vibration thaum tsav tsheb hauv ob lub iav (tus yam ntxwv ntawm DSG-7 clutch hnav). Qhov tseeb, qhov ua rau ntawm cov kev vibrations yog lwm yam, thiab kev yoog raws li qhov no yuav tsis pab.

Kev hloov pauv ntawm kev hloov pauv cov ntsiab lus thiab clutch dawb ua si feem ntau pab ua haujlwm ntawm lub thawv thiab ua kom lub neej ntev ntawm mechatronic. Nyob rau hauv cov txheej txheem no, lub iav hloov cov ntsiab lus yog rov pib dua, lub mechatron actuation pressures raug kho, thiab lub free thiab siab calibration ntawm lub clutch discs yog calibrated. Pom zoo ua adaptation txhua 15 txhiab kilometers khiav. Txawm hais tias ntawm cov neeg tsav tsheb muaj ntau tus neeg uas muaj tus cwj pwm tsis zoo rau kev hloov kho, yog li nws yog nyob ntawm tus tswv lub tsheb txiav txim siab seb yuav hloov kho lossis tsis ua.

Nyob rau hauv parallel nrog clutch diagnostics siv cov cuab yeej software, nws tseem tsim nyog kuaj xyuas lwm lub tsheb, uas yog, luam theej duab rau qhov yuam kev uas twb muaj lawm. uas yog, koj tuaj yeem tshawb xyuas cov mechatronics nws tus kheej. Txhawm rau ua qhov no, mus rau pawg 56, 57, 58. Yog tias daim teb uas tau nthuav qhia muaj ib 65535, txhais tau tias, tsis yuam kev.

Kev kho Clutch

Nyob rau hauv ntau lub tsheb, lub clutch system yuav raug kho. Qhov no tuaj yeem ua tiav ntawm koj tus kheej, lossis hu rau tus tswv kom pab. Yog hais tias lub tsheb muaj tsawg mileage ntawm lub pob tawb clutch, txoj kev kho no yog qhov zoo heev. Yog hais tias lub mileage tseem ceeb, thiab ntau dua yog li lub clutch twb tau hloov kho, nws yog qhov zoo dua los hloov nws cov discs lossis tag nrho lub pob tawb (nyob ntawm seb qhov degree thiab qhov tawg ntawm qhov tawg).

Nws yog qhov zoo dua los kho lossis hloov kho sai li sai tau, thaum thawj cov cim qhia ntawm kev puas tsuaj tshwm sim. Qhov no yuav ua kom tsis tsuas yog caij tsheb zoo xwb, tab sis tseem yuav txuag nyiaj ntawm kev kho kim.
