The 747 at least has a nose gear steer/rudder interconnect mechanism
located under the flight deck floor (first class roof) which is controlled
by an actuator.  The actuator moves a certain way based on the speed of
the a/c (an input from another system) which in turn governs the effect of
the rudder pedal on nose gear steering movement.
