Hydraulic assist steering system consists of power steering pump assembly, steering gear assembly, steering
fluid pipe and steering fluid reservoir assembly, etc. This system can reduce the steering effort when driver
operates steering wheel, thus improving operation convenience and driving safety.

Steering Gear Assembly

Steering gear assembly is rack & pinion type, which is characterized by simple and compact construction and
high steering sensitivity. The piston-rod is integrated with rack, and there is a boot at the connection between
steering tie rod assembly and rack. The length of steering tie rod can be adjusted properly to match with the
toe-in. Tie rod ball pin assembly and steering knuckle are connected and tightened by locking nut.

Power Steering Pump Assembly

Power steering pump assembly is connected with steering gear assembly through high pressure fluid pipe,
and connected with steering fluid reservoir assembly through fluid suction pipe. Never operate the power
steering pump assembly without fluid. Try to avoid turning the steering wheel to limit position for more than 5
seconds during use.

Steering Fluid Pipe

Steering fluid pipe is used to deliver power steering fluid. Steering fluid pipes are divided into steel pipe, hose
and hybrid type according to the length and operating features of each component. Ferrule connection is
adopted between steel pipe and hose of high pressure fluid pipe assembly. The Joint bolt and O-ring are used
between steel pipe and component, and the hose and clamp are used between hose and component. And all
these provide reliable sealing.

Steering Fluid Reservoir Assembly

Main functions of steering fluid reservoir assembly are to store and supply fluid to the steering fluid pump and
system.

Operation

Steering gear assembly converts the circular motion of steering wheel into the linear motion of rack by
engaging pinion and rack inside the steering gear assembly. Power steering pump assembly delivers fluid into
steering gear assembly to drive pistons to move toward the direction made by driver. Piston transmits force to
steering knuckle by steering tie rod assembly, thus reducing the steering effort needed when driver turns
steering wheel. If steering assist is ineffective, more steering effort is needed.
