4WD ir padangos

[Dzhedaj]

Taigi, kilo man toks klausimas, kaip shviezhiam 4WD auto vartotojui

FWD ir RWD mashinoms jokio skirtumo ish esmes, ar priekyje ir gale padangos vienodos, ar ne...svarbu, kad butu vienodos ant vienos ashies...

O kaip yra 4WD automobiliams? Ar turi tai kokios nors itakos? Gal kas nors negerai darosi su viskozine jungtim ar smth?

Cia nebutinai tik subaru ar mitsubishi jai pas tave 4 varomi tai padangos butinai turi buti visos vienodos

[Dzhedaj]

Naturaliai kyla klausimas kodel?

Be to nusidevejimas vistiek juk skiriasi, priekis labiau devisi net ir 4wd, posukiuose tenka ju didesnes apkrovos...

Be to abejoju ar kuris gamintojas rekomenduotu ir 2wd mashinoms deti skirtingas padangas

skirtingu protektoriu, plociu, auksciu padangu trintis yra skirtinga tode (bent jau audi) mirtis pareina movai

Viena ziema vazinejau su zemesnem padangom gale, daugiau nenoreciau.......

Ash nekalbu apie skirtingo aukschio padangas, turiu omeny tik skirtingo protektoriaus

Vnz itariau, kad turi buti jos vienodos ir shiaip, o dar radau Toyo saite info, kad amerikoj ne viena auto uzhsidege, del to kad perkaito diferencialas...O taip nutikdavo pakeitus tik 2 padangas i naujas, o kitas 2 palikus plikas

Nu cia manau mums negresia, pas mumi 4WD viskozine jungtis ir normaliai vaziuojant galinis tiltas nedirba. O drozt tikiuosi nei vienas nesiruosiam...
Girdejau jog quattro sistemoje tai sitie bajeriai lengvai nepraslysta....
Del skirtingo protektoriaus tai manau bedu nebus, as jau treti metai vasarines skirtigo protektoriaus droziu ir kazhko ypatingo dar neatsitiko...

nezinau kaip pas Aiskste,bet pas mane prieki uzdeta grazi plasmasele "All time 4 wd"(kuria dabar nuemes ),todel kaip suprantu(ir bandes)pas lancerius jie sukasi visi 4 visa laika Ir kiek kalbejas su rimtais dzipistais,viena is pagrindiniu salygu yra visos vienodos padangos su vienodu protektoriaus gyliu,ko nesilaikant atsiranda problemos kurias paminejo Senis ir kiti forumo dalyviai....
p.s. jei vazinetum tik slydziais keliais protektoriaus gylys,padangu aukstis,skirtingi rashtai nekeltu tu minetu problemu.Atsirastu tik stabilumo problema...

Viscous coupling is an application used in all-wheel drive systems. The idea of the coupling is based on a special fluid which is inside of a hermetic container. In the container there are numerous plates which are installed very close to each other. Odd plates are attached to a cylinder-like outer rim which is fixed to a cardan shaft. Even plates are attached to a bar-like inner axle which is fixed to the other half of the cardan shaft. The system works when the spinning speed difference of the inner and outer axles occur (this happens when the front wheels are slipping and the rear wheels are not). The special fluid inside the coupling unit gets heated by friction when the plates are spinning at different speed and gets sticky or solid in fractions of a second. The fluid returns to liquid in no-time when the spinning speed difference has disappeared due the same rotation speed of front and rear wheels. So as a result, when the front wheels slip, the fluid gets hot from friction and it makes the axles stick together and makes power go to the rear wheels as well.
Example:
If a vehicle is built so that the front wheels get power from the motor and the rear wheels are getting the power from the cardan shaft through a viscous coupling, the power ratio between the front and rear wheels could change from 100% front and 0% rear to 50% front and 50% rear. The 50/50 is naturally a situation of maximum stuck between the ends of the cardan shaft....
