Effects of Negative Offset Geometry
(1) When the brake pedal is depressed on a running vehicle
with one wheel on a slippery surface, a force is produced
which causes the vehicle to pull toward the side with larger
road surface resistance (to the right in the case illustrated
at the left).
(2) Because of the dynamics resulting from the negative offset,
moments Fc and Fo are generated in both wheels around
point A (the point where the kingpin axis meets the ground).
Since the magnitude of these moments is proportional
to the road surface resistance, a pull force is produced
in the wheels to turn them toward the side with either
the Fc or Fb moment whichever is greater (to the left
in the illustrated case).
(3) This means that the wheels pivot toward the direction in
which the vehicle’s pull force resulting from the difference
in road surface resistance is compensated for, thus main-
taining the vehicle’s straight-line movement.
