3.2 INTRODUCTION
(1) Gear Pump
(2) Priority Valve
(3) Power Steering Unit
(4) Hydraulic Hose (RH)
(5) Hydraulic Hose (LH)
An exclusively hydraulic load reaction type of power
steering is applied to this system, and as the exclu-
sively hydraulic model connects the steering controller
and the steering cylinder with only a hydraulic pipe, the
control is available also only with hydraulic power trans-
mitted to the cylinder.
Thus there is no mechanical conveyance such as steer-
ing gear, pitman arm or drag link for simple implement.
(6) Steering Cylinder
(A) To the Transmission Case
(B) To the Hydraulic Block
The exclusively hydraulic type of power steering is clas-
sified into Non-Load Reaction model and Load Reac-
tion model according to the cylinder port disconnected
or connected with the control valve at neutral position,
and the latter model is applied to the tractor. For this
model, the steering wheel returns almost as straight-
ened as that of an automobile when the hand is off the
steering wheel if not exactly though.
