1. Drive system
1.1 Summarize
The drive system consists of gear box assembly, differential mechanism assembly and drive
axle, the reducer drive gear connects directly to drive motor.The travel speed increases with the
increment of rotational speed of drive motor, And when the rotational direction of the motor
changes, the travel direction changes too.
1.2 Reducer casing and differential mechanism
Reducer,of which the two pairs of column screw gear make the rotational speed decline of the
output axis of travel motor and make the twist moment rise from travel motor,and then send the
twist moment to differential,lies between drive axle and travel motor,see figure 2-1

Figure 2-1 Reducer
Differential mechanism, of which the front connects to axle shell,is installed on the front-half
shell by the bearing block
in on two sides. The shell of the differential is left-right subdivision in
construction,and there are two half axle gears and four planet gears in it.see figure 2-2
