7.2.2 Description and Operation
7.2.2.1 Description and Operation
Warning!
Refer to "Steering Wheel in the Full Turn Position Notice"
in "Warnings and Notices".
Warning!
Before disconnecting the mechanical steering column
assembly with the power steering gear, the wheels
should be kept in the straight front positions and the
mechanical steering column assembly must be in the
LOCK (lock) position.
After disconnecting the above components, do not move
front tires and wheels, otherwise it will cause some parts
are not positioned correctly during the installation
process and lead to mechanical steering column airbag
assembly spiral off center position, and damage the
airbag spiral coil.
Power Steering Pump Assembly Instructions
Power steering pump assembly provides hydraulic pressure for
the whole steering system, and it is a vane-type pump.
Power steering pump assembly consists the following
components:
–
Pump Housing
–
Impeller Pump Rotor
–
Pump Impeller Blades
–
Impeller Pump Front Side Panel
–
Impeller Shaft
–
Impeller Shaft Bearings
–
Fluid Pressure Switch Assembly
–
Flow Control Valve Assembly
–
Fluid Pipe
–
Fluid Seals and O-ring
Following components are installed in the pump housing side
hole :
–
Fluid Pipe
–
Fluid Pressure Switch Assembly
–
Flow Control Valve Assembly
Flow control valve assembly consists of the following
components:
–
Filling Joints
–
Flow Control Valve
–
Flow Control Valve Compression Spring
Flow control valve hole and the outlet connector is an
integrated part. Flow control valve's primary role is to prevent
high steering pump pressure.
Power Steering Gear Assembly Instructions
Power steering gear assembly uses the rack and pinion
hydraulic power steering.
When turning the steering wheel, steering wheel movement is
passed to the steering control valve shaft, steering control
valve axle pinion and rack mesh, so the rack moves left and
right.
Power steering gear assembly has a steering control valve.
Steering control valve assembly introduces high pressure fluid
from the power steering pump to both sides of the rack piston
to move the rack piston. Integral power cylinder piston and rack
connection can convert rack piston hydraulic pressure to linear
force and move the rack. linear force is transmitted to the inner
and outer steering tie rod, and then passed to the steering
knuckle, which turns the wheel.
If the auxiliary hydraulic fails, manually control steering will
require much greater effort.
Power Steering Fluid Description
Warning!
After adding or completely replace the power steering
fluid, make sure use the correct power steering fluid.
using the incorrect power steering fluid will cause
damage to hoses and seals, and oil leaks. Refer to this
chapter for recommended power steering fluid.
Power steering fluid reservoir and pipe assembly is made from
plastic, and the fluid level within the reservoir can be seen from
outside. There are fluid level mark on the fluid reservoir side.
The marks are used to indicate the power steering fluid level.
Make sure use proper power steering fluid. Refer to .
–
After preheating the power steering fluid, its temperature is
about 75 °C -80 °C (167-176 ºF). Power steering fluid level
should be between "HOT-MAX" and "HOT-MIN".
–
After cooling the power steering fluid, its temperature is
about 20 °C -25 °C (68-77 ºF). Power steering fluid level
should be between "COLD-MAX" and "COLD-MIN".
