3. OVERVIEW
The power steering system consists of pump, oil reservoir, rack and pinion gear. The power
steering pump is a vane type and delivers hydraulic pressure to operate the power steering
system. The pressure relief valve in pump controls the discharging pressure.
The rotary valve in rack and pinion gear directs the oil from the power steering pump to one
side of rack piston. The integrated rack piston converts the hydraulic pressure to linear
movement. The operating force of rack moves the wheels through tie rod, tie rod end and
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 steering wheel is conveyed to pinion, and the movement of
pinion moves the rack through pinion gear combined to rack gear.
