Thedifferentialsystemistorotatetheleftwheelandrightwheelatdifferentspeedsforsmoothturning.When
turning,thissystemrotatestheinnerwheelintheturningdirectionslowerandtheouterwheelfastertoturn
thevehicleinthedesireddirection.
Also,whenawheelgotstuckinmud,itishardtoescapethepitsincethewheelinmudwithnofrictionrotates
atfasterspeedandthewheelonroadwithfrictiondoesnotrotateduetothedifferentialsystem.Topreventthis
situation,thevehicleisequippedwiththedifferentiallock.Thedifferentiallockmovesthedifferentiallockslide
toxthedifferentialcaseanddifferentialsidegeartogetherwiththepin,resultinginrotationofthesidegear
ontheothersideaswell.Therefore,thewheelsonbothsidesarerotatedatthesamespeedtoescapethepit.
Thedifferentialsystemconsistsoftheringgear(1),differentialcase(2),differentialsidegear(3),differential
pinion(4),differentialpinionshaft(5)anddifferentiallockslide(6).
