SYNOPSIS
The proposed mechanism is to lock the
differential. By locking the differential the differential is disengaged from
the axle. Thus the power is directly transmitted to the axle and hence to the
wheels. This will considerably reduce the power loss in some occasions when
unwanted loss is happening due to the transmission if power from the shaft to
the differential and then to the axle and hence to the wheels. So in mechanism
the unwanted power loss in the due course of transmission through the
differential is reduced.
There are some drawbacks in the
existing mechanism and we overcome it in the proposed project. The first is
while climbing in steep hills the differential is not really needed as the
speed of the vehicle is low. And also there are some transmission loses in the
differential. So at this time the unit is locked and the loss is overcome. Then
when a heavy truck is struck in a pit or mud it is very difficult to recover
the truck as the differential unit cuts the power which is to be transmitted to
the wheel struck. So in this project the unit is disengaged and power is
directly given to the axle by pneumatic means and so the recovery is made
easier. This is even made use in the vehicle to be driven in the dense forests
and even in dessert.
