Automatic Hub Locks Automatic Hub LocksAutomatic Hub Locks Automatic Hub Locks
Automatic Hub Locks
While driving in 2H mode this mechanism on the front axle
hub allows the hub to free wheel. This avoids the unnecessary
spinning of front drive components and results in fuel saving,
reduced noise and longer component life.
As soon as 4H or 4L mode is selected the hub gets
automatically connected to front drive line to increase the
traction.
Limited Slip Differential Limited Slip DifferentialLimited Slip Differential Limited Slip Differential
Limited Slip Differential
(Standard on 4x4 and optional on others)
A standard differential delivers torque equally to each wheel.
In case one wheel loses traction and begins to spin, the
differential distributes the rotary speed unequally but with
same torque. This can cause the wheel with good traction to
slow down or stop while the wheel which lost traction rotates
with increased speed. Such a situation can prevent the vehicle
from moving.
The limited slip differential provided in the rear axle takes
care of such situations. The clutch lock arrangement provided
internally, ensures that in case one wheel loses traction and
begins to slip, a locking action takes place which prevents
differential action and both wheels turn at the same speed.

gear box for driving front live axle along with rear axle.
The following 3 selector positions are provided on the knob.

Thus unnecessary spinning of one wheel is avoided and torque
is transmitted to both wheels, thus assisting the vehicle to traverse
loose terrain. However during normal driving, the differential
action takes place in the same manner as in a standard differential.

Four Wheel Drive Operation Four Wheel Drive OperationFour Wheel Drive Operation Four Wheel Drive Operation
Four Wheel Drive Operation
In 2-H mode, only the rear two wheels of the vehicle are
powered by the engine and the front wheels are merely
pushed. By shifting to four wheel drive mode (4H or 4L)
the rear as well as the front axles get geared to the engine
through transfer case and transmit the engine power to all
four wheels. This gives the vehicle increased traction.
In 4H mode, the transmitted engine torque and vehicle
speed remain the same as in 2H. However, when you shift
to 4L mode engine torque is multiplied and vehicle moves
at low speed in the same gears with increased traction. 4L
mode is provided for negotiating sharp gradients or driving
through loose soil/sand.

Turn the selector knob from 2H to 4H position. 4H indicator

can be done at any speed upto 65 km/h (40 mph). No
pressing of clutch pedal is required.3. 3.3. 3.

Free Wheeling of Front Hub
After shifting from 4H to 2H, for effecting free wheeling of front
wheels, direction of vehicle motion needs to be changed. If
the vehicle was moving forward in 4H then bring it to halt and
engage reverse gear of main gear box. (If it was moving reverse
in 4H mode then stop it, and then engage forward gear of
main gear box.) After stopping and changing the gear the
vehicle must travel in opposite direction for a minimum of three
meters, before free wheeling takes place.
