3.1.5 Description and operation

3.1.5.1 Mechanical steering system
The main component of the mechanical steering
system is two-way output gear rack-type manual
steering gear. By control of steering wheel, the
power is transmitted to gear of the manual steering
gear through upper and lower steering shafts.
Linear force that shifting rack is generated by gear
driving and transmitted to knuckle through steering
linkages, thus, the driving direction can be changed.
