6C-2  POWER STEERING GEAR

POWER RACK AND PINION

The power steering rack and pinion system has a rotary
control valve that directs hydraulic fluid coming from
the hydraulic pump to one side or the other side of the
rack piston. The integral rack piston is attached to the
rack. The rack piston converts hydraulic pressure to a
linear force that moves the rack left or right. That force
is then transmitted through the tie rods to the steering
knuckles, which turn the wheels.

DESCRIPTION AND OPERATION

If power rack and pinion steering is not available, manu-
al rack and pinion control is used; however, with this
system, more steering effort is required. The movement
of the steering wheel is transferred to the pinion. The
rotary movement of the pinion is then transferred
through the pinion threads, which mesh with teeth on
the rack, thereby causing the rack to move in a linear
direction.

A vane-type of hydraulic pump provides hydraulic pres-
sure for both steering systems.
