General:
The power steering gear is designed for a system pressure of 150 bar and a maximum torque of 6726 Nm from the sector shaft.

• The steering gear ratio is variable at 17-20:1.  The power steering gear has an integrated pressure limiting valve and a hydraulic wheel end lock.
• The wheel end lock is self-adjusting.

Function Description:
Operation without power steering:

• If a fault occurs and there is no power steering, the power steering gear will operate as a mechanical steering gear. The vehicle can be steered but the steering will be much heavier.
• When the steering wheel is turned, the torque is transferred to the power steering gear input shaft.
• A torsion bar is fixed onto the input shaft and onto the worm screw. When the torsion bar has been turned approximately 7°, a pin engages and transfers the torque mechanically to the worm screw.
• The set of balls between the worm screw and piston transfers and reinforces the torque to the piston which is then displaced into the steering gear housing cylinder.
