GENERAL INFORMATION

Description

21–

The differential case contains 2 drive shaft gears, planetary gear shaft and 2 planetary gears. The driven gear
of final drive is connected together with differential case by bolts. The planetary gear shaft, which is fixed on
differential case, drives the planetary gears to rotate when the differential operates, thus driving the drive shaft
gears to turn. The drive shaft gears are connected with drive shaft to transmit effort to wheels.

Operation

 When driving on a bumpy road or turning, the travel distance of outside wheels is longer than that of inside

wheels, so the speed of outside wheels is faster, which breaks the balance of vehicle drive train.

 The planetary gear mechanism in differential can transmit speed difference between outside and inside

wheels via drive shaft when turning. It forces the planetary gears to rotate, thus allowing the inside and
outside wheels to spin at two different speeds in order to balance the speed difference and keep the
vehicle moving smoothly.

 The final drive is a component to reduce the rotation speed and increase the torque of drive train.
