1. OVERVIEW
The power steering has been designed to make the wheel move more easily than in a manual steering
system. The hydraulic power assists the process utilizing hydraulic fluid. The fluid increases pressure
in the power steering pump and aids the movement of the steering mechanism. The power steering
system consists of pump, oil reservoir, rack and gear box. The power steering pump is a vane type
and delivers hydraulic pressure to operate the power steering system. The pressure relief valve in the
pump controls the discharging pressure. The rotary valve in the rack and the pinion gear directs the oil
from the power steering pump to one side of the rack piston. The integrated rack piston converts the
hydraulic pressure to linear movement. The operating force of the rack moves the wheels through the
tie rod, the tie rod end and the steering knuckle. Even though the hydraulic pressure cannot be
generated, a driver can steer the vehicle without power assist but it needs very high steering force. In
this case, the operating force of the steering wheel is conveyed to the pinion, and the movement of the
pinion moves the rack through the pinion gear combined to the rack gear.
