The steering gear has the following features:
-
It is a torsion-bar type of hydraulic assisted system. The system furnishes power to reduce the amount of effort required to turn the steering wheel.
-
It also reduces road shock and vibration.
-
It includes a worm and one-piece piston which is meshed to the gear teeth on the steering sector shaft.
-
It includes a rotary-style hydraulic valve consisting of:
-
an input shaft.
-
control valve sleeve.
-
torsion bar.
-
The valve is pinned to the worm and the input shaft is connected to the worm through the torsion bar.
-
The hydraulic action is generated by a relative rotary position between the power steering gear input shaft and control and the worm/sleeve
assembly.
