The steering system is hydrostatic and includes a
power steering motor, hydraulic relief ass’y and steer-
ing cylinder. See above steering system. This system
is designed optimally, and results in a high front wheel
steering angle and small turning radius.
The steering power of the steering wheel is transmit-
ted to the front wheel through the power steering motor,
hydraulic hoses and steering cylinder. Hydraulic power
supplied from hydraulic relief ass’y make steering easy.
If hydraulic power isn’t supplied from the hydraulic re-
lief ass’y, the steering motor will manually actuate the
internal trochoid pump by itself.
The power steering motor has a relief valve for protect-
ing the hydraulic circuit. If the steering wheel is con-
tinuously rotated, when the front wheel reaches the
maximum steering angle or resistance of traveling
wheel is too large, the relief valve is actuated.
Continuous duty of the relief valve causes the oil tem-
perature to rise and possibly cause the relief valve to
malfunction, which may seriously affect the steering
parts.
