Monitor for self levelling headlights - having inductive sensor fitted inside shock absorber to give level control signal

摘要

The piston rod of the shock absorber is hollow and slides over a ferrite core fixed to the bottom of the damper. The rod is fitted with two induction coils in series and the amount of displacement over the ferrite rod alters the induction of the system and provides a signal for the self levelling control. The system is simple, compact and protected from road dirt and the signal is directly proportional to damper and thus suspension movement.
