CONSTRUCTION
id
A high mounted upper arm and two lower arms
act like a double-wishbone arrangement. In this ar-
rangement, a virtual kingpin axis is formed on the
line connecting the external vertex of the upper arm
triangle and the point where the lines extended from
the two lower arms intersect. This construction pro-
vides the following advantages:
l
A negative offset geometry is established which
assures better stability during braking.

l
Reduced offset between the virtual kingpin axis
and the wheel center results in a lower steering
movement at the time when the vehicle is accel-
erated or goes over a bump on road, assuring
better stability.
l The high-mounted upper arm helps improve
the wheel supporting rigidity.
l
The multi-link suspension, like a double-wish-
bone suspension, suffers little change in “cam-
ber to ground” when a rolling motion occurs,
assuring better stability during cornering.
