5. STEERING SYSTEM
- 80 -
The returning oil from the power cylinder flows, passing through the cylinder port R, groove in the
valve housing, oil hole in the sleeve, groove in the spool, oil hole in the sleeve, and groove in
the valve housing, back to the oil tank.
(c) When steering wheel is turned clockwise
As the steering wheel is turned clockwise, the
grooves in the spool shift to the right in relation to the
oil holes and grooves in the sleeve so that oil holes
in the spool get out of line with holes in the sleeve.
The oil that has flowed into groove thus far begins
to flow into oil hole in the sleeve and then flows
through grooves and in the spool, oil hole in
the sleeve, and oil passage in the valve housing to
the hydraulic motor. The hydraulic motor thus rotates in
the clockwise direction and the oil discharged from the
hydraulic motor flows through oil hole in the sleeve,
groove in the spool, and oil hole in the sleeve to
the cylinder port R in the housing and thus actuates the
power cylinder.
The returning oil from the power cylinder flows,
passing through the cylinder port L, groove in the
housing, oil hole in the sleeve, groove in the spool,
oil hole in the sleeve and groove in the housing
back to the oil tank.
(2) Relationship between the rotating speed and operating force of the steering wheel
The force required to operate the orbitrol is basically a valve operating force (the force required to
compress the centering spring: 2.9 N-m {0.3 kgf-m} [2.14 lbf-ft]). That is, there is no mechanical linkage
between the steering wheel and the tires, and thus the operating force of the steering wheel remains
constant regardless of the rotating speed of the steering wheel. The discharge of oil from the orbitrol
rotor to the steering cylinder is 96 cc/revolution.
(3) Neutral feedback of orbitrol
The neutral feedback function of the orbitrol is performed by the valve switching over the oil passages
according to the reaction force of the centering spring. (If the steering wheel is turned and then released
with the engine turned off, it will automatically return to the straight-ahead position.) Should the neutral
feedback not function properly, the steering wheel might turn by itself when the operator does not turn it.
