Steering Gear: Description and Operation








Power Steering Gear Description

The power rack and pinion steering system has a control valve which directs the hydraulic fluid under pressure to either side of the rack piston. The piston attaches to the rack. The rack piston uses the hydraulic pressure in order to move the steering rack to the left or to the right. The steering rack moves the tie rods. The tie rods move the steering knuckles. The steering knuckles turn the front wheels.
If the hydraulic assist fails, the vehicle maintains manual control. This condition requires more steering effort.
