Steering Gear: Description and Operation
Tracker Power Steering Gear
Fig. 1 Cross-sectional view of Tracker power steering gear
The input shaft in the steering gear has a torsion bar which connects the input shaft with the main shaft, Fig. 1. As the steering wheel is turned, the
input shaft turns, moving the spool valve according to how much the steering wheel is turned. This valve movement allows fluid to flow causing
hydraulic pressure to be applied to the piston providing assistance to steering effort.
When the steering wheel is straight forward, the spool valve does not operate and fluid flows from the pump through the short circuit back to the oil
tank. When the steering wheel is turned right, the input shaft pushes the spool valve to the right, allowing hydraulic pressure to be applied to the right
side of the cylinder.
