STEERING COLUMN, AND HYDRAULIC CONTROL UNIT

Downloaded from www.Manualslib.com manuals search engine b) Control unit : ’
The contra! unit located below the steering wheel, consists of a distributor slide-valve ( C ) which. when
hydraulic pressure on either side of it is the same ensures in chamber 1 the necessary pressure for the
steerinq piston

Movement of rack causes movement of its control pinion. pinion B and pinion D Pinion F being then locked in posi-
tion, pinion D acts on rockers E. which in turn brinq back slide-valve C to its position of equilibrium.
NOTES :
1) Manual operation is ensured by shaft A being mechanically connected to pinion B after cancellation of clearance
a J )).
2) The steering rack is hydraulically locked for any steering position, which ensures great directional stability of
the vehicle.

Downloaded from www.Manualslib.com manuals search engine a ) Mechanical principle
After having steered the driver lets go of the
s teerinq wheel
Piston F applyinq pressure to cam H, causes the
latter to rotate.
- Pinion B in one piece with the cam rotates control
shaft A.
- Rotation of control shaft A, is transmitted to
pinion E which causes rockers D to tilt and
slidecvalve C to move which moves the rack.
This movement stops when roller G reaches
the hollow part of cam H ( ro/~/i<,//~/ /or(//((’ is

NOTE Pressure supplied by the steering governor
is applied to piston F via a variable output requlator
in order to slow down the return of the steerinq to the
v straiqht-ahead a) position.

Variable output regulator :
Wh(‘I/ \I< criq .’ return of piston F causes the

- Fluid flows throuqh channel M ( valve L closed )
and through calibrated port N, forcing back sleeve I.
= Sleeve I compresses sprinq K sliqhtly and slowly
covers ports J as piston F moves.
