Diferential fata blocabil


alibotean

Postări Recomandate

Am observat ca pe fata la roti/in mijlocul jentii aveam ceva ce parea un antifurt :) am vb azi cu fostul proprietar si mi-a spus ca de fapt de acolo se blocheaza diferentialul fata. Are 2 pozitii AUTO si LOCK.

 

Imi poate explica si mie cineva cand ar trebui sa il blochez si daca pe auto se blocheaza si el? si ince situatii. Multumesc.

Re: Diferential fata blocabil

 

Your NISSAN is equipped with one of two

4WD systems, auto-lock free-running hubs

or manual-lock free-running hubs.

The auto-lock free-running hub is designed

to allow for automatic 4-wheel drive engagement

when the shift lever is moved to

the 4H or 4L position. If your vehicle is

equipped with this system, follow these operational

cautions:

CAUTION

c The auto-locking hubs will make a

clicking noise when engaging and

disengaging. This is normal.

c Accelerating quickly from a stop after

shifting from 2-wheel drive to

4-wheel drive may not allow engagement

of the auto-locking freerunning

hubs and may cause a clattering

noise. Continued use of the

vehicle with this noise may damage

the hub lock. In such a case, release

the accelerator pedal to reduce the

engine speed or stop the vehicle.

c If the auto-locking hubs make a clattering

noise after shifting from

4-wheel drive to 2-wheel drive, stop

and move the vehicle about 7 to 10

feet (2 to 3 m) in reverse.

c Under extremely cold conditions

[below 5°F (-15°C)], the front axle

shafts may rotate even with the

transfer lever in the 2H position. If

this occurs, the auto-locking hubs

may make a clattering noise. To

avoid this, drive first in 4-wheel drive

to warm up the vehicle and differential

gear oil. Then, shift to 2-wheel

drive.

c In cold weather, it may be necessary

to reduce speed or stop the vehicle

in order to shift from 2-wheel drive to

4-wheel drive.

c When shifting into or out of 4-wheel

drive while driving, do not stop shift

lever movement midway. An incomplete

shift may cause a clattering

noise from the auto-locking hubs.

Continued use of the vehicle with

this noise may damage the hub lock.

Drive in 4-wheel drive to stop the

noise. Shift to 2-wheel drive as described.

TO SHIFT

TRANSFER CASE:

SHIFT PROCEDURE FOR AUTO-LOCK FREE-RUNNING HUBS

From 2H to 4H

Move the transfer lever to 4H at speeds below 25 MPH (40 km/h). It is not necessary to depress the clutch pedal. Perform

this operation when driving straight.

From 4H to 2H

Move the transfer lever to 2H. This can be done at any speed, and it is not necessary to depress the clutch pedal. Perform

this operation when driving straight.

NOTE:

For 2-wheel drive operation, set the free-running hubs in the disengaged position. AUTO-LOCK hubs will not disengage

until the vehicle is moved about 3 feet (1 m) in the opposite direction of travel:

c When driving forward, stop and move 3 feet (1 m) in reverse.

c When backing up, stop and move 3 feet (1 m) forward, then move the vehicle about 3 feet (1 m) in reverse.

This will allow for better fuel economy, quieter ride and less component wear.

From 4H to 4L or 4L to

4H

1. Stop the vehicle.

2. Depress the clutch pedal.

3. Depress the transfer lever and move it to the desired 4L or 4H position.

From 2H to 4L

1. Stop the vehicle.

2. Depress the clutch pedal.

3. Depress the transfer lever and move it to 4L. Change gears quickly and smoothly.

From 4L to 2H

1. Stop the vehicle.

2. Depress the clutch pedal.

3. Depress the transfer lever and move it to 2H.

NOTE:

Follow the NOTE shown in shifting from 4H to 2H.

4-18

The manual-lock free-running hubs are designed

to allow you to engage or disengage

the front drive shaft to the front wheels.

Before driving, set the free-running hub to

the desired position:

c 2-wheel operation — Turn the knob to

the FREE position.

c 4-wheel operation — Turn the knob to

the LOCK position.

Be certain to align the S mark on the knob

with the c mark on the wheel hub.

CAUTION

c Never drive in 4-wheel drive (4H or

4L) with the free-running hubs in the

FREE position.

c Do not drive your vehicle with the

left and right free-running hub set to

different positions.

c For the first 300 miles (483 km) it is

recommended that you drive in the

2H position with the free-running

hubs set in the LOCK position.

c To ensure proper lubrication of front

drive components, drive in the LOCK

position for at least 10 miles (16 km)

each month.

Re: Diferential fata blocabil

 

Asa functioneaza lucrul ala, cu mentiunea ca in pozitia AUTO e automat, iar in pozitia LOCK reactioneaza ca un mecanism manual.

 

NU are nici o legatura cu blocarea diferentialului, cupleaza planetarele din fata cu butucul rotii.

 

Sfat:

1. Int otdeauna cuplarea se va face din pozitia oprit.Dupa ce ai terminat treaba cu 4x4 si ai adus maneta in pozitia 4x2, obligatoriu rulezi 3-4 metri inapoi, pentru a decupla planetarele. Toate astea pt pozitia AUTO, pt pozitia LOCK planetarele nu se vor decupla indiferent de pozitia manetei de cuplare.

 

2. 4x4 automat se va cupla inainte de intrarea in noroi sau altceva in care poti ramane impotmolit. In cazul in care te-ai trezit blocat inainte de a apuca sa cuplezi fata, obligatoriu se vor cupla MRL-urile manual(pozitia LOCK) inainte de a cupla restul transmisiei din maneta. Daca nu vei proceda asa risti sa barbieresti danturile din interiorul MRL-ului.

 

3. Atunci cand iesi in teren greu : paduri , noroaie ,zapada etc. cupleaza MRL-urile in pozitia LOCK cu ajutorul cheiei originale de roti, sau daca nu o ai foloseste o cheie de bujii din aceea de tabla care exista pe la Dacii.

Re: Diferential fata blocabil

 

Mersi pentru sfaturi, nu stiam ca trebuie sa merg 3m in directie opusa la cuplarea 4x4 sau 4x2 de la maneta de transfer. Am mers weekendul trecut si am cuplat si decuplat fara sa faca asta :) sper ca nu s-a bulit nimic.

 

Am o nelamurire la toata povestea asta cu AUTO si LOCK. Care este diferenta intre a cupla din maneta de transfer pe 4H sau direct de la roata?

Re: Diferential fata blocabil

 

De la roata nu cuplezi toata transmisia, doar planetarele. Daca ai ramas impotmolit, atunnci cand cuplezi din maneta, se vor invarti planetarele in timp ce rotile din fata raman pe loc. O roata dintata, care se invarte nu se va cupla cu una care sta pe loc sau care are turatie diferita.

Am scris sa mergi inapoi, dupa ce ai decuplat din maneta. Nu ca sa cuplezi, ci ca sa decuplezi planetarele de roti.
