1.1 Reduction box
The truck used reduction box, light and controllable vehicle driving device, which adopts two
grades reduce speed gear, namely grade-one cylindrical gear and grade-two spiral bevel gear.
This reduction gear box owns traits like small size, light weight, large transmission ratio, small
radius of gyration, high efficient and simple structure, which enables turn on site and equip with
motor vertically that cause the radius of gyration on the carriage is small. Moreover, this reduction
gear box does not need to shift, but realize direction shift (forward or reverse) directly by motor
positive inversion, and is easy to use and maintain.
