• This is the device that splits the
power between the front and rear axles on a four-wheel
drive car
• The transfer case on a part-time
four-wheel-drive system locks the front-axle driveshaft to
the rear-axle
driveshaft,
• So the wheels are forced to spin at
the same speed
• Some transfer cases, also contain
an additional set of gears that give the vehicle a low
range
•This
extra gear ratio gives the vehicle extra torque and a super-slow output speed
• In
first gear in low range, but incredible
torque is produced at the wheels
•
This allows drivers to slowly and smoothly creep up very steep hills
