POWER STEERING SYSTEM
GENERAL
1. POWER STEERING SYSTEM 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.
