Steering Gear: Description and Operation

The Constant Control Full Time Power Steering consists of a hydraulic pressure pump, a power steering gear and connecting hoses. The power steering gear consists of a gear housing, containing a gear shaft and sector shaft, a power piston with gear teeth milled into the side of the piston which is in constant mesh with the gear shaft sector teeth, and a worm shaft which connects the steering wheel to the power unit piston through a coupling. The worm shaft is geared to the piston through recirculating ball contact, and the steering valve which is mounted on top of the steering gear directs system fluid flow.
