SUSPENSION

N732000AA

Both the front and rear suspension are a new multi-

effort for the best compromise between high-level

link design which is the result of the development

steering stability and ride.

1. New multi-link design

2. Increased caster angle, reduced kingpin angle (front)
3. Reduced initial camber (front)
4. Adoption of virtual kingpin axis scheme
5. High-mounted front and rear upper arms
6. Increased rigidity of front cross member
7.

Front shock absorbers with a damping force control valve

for very low and low speed operation

8. Use of a ball joint type stabilizer link
9.

Use of an anti-dive geometry for the front and an anti-lift

geometry for the rear

10. Use of an anti-squatting geometry

1. Reduced shock absorber friction

2. Increased wheel stroke

Reduced road noise

Crossmember with vibro-isolating supports

Toe adjustment mechanism in front and rear suspensions

Front Suspension

The front suspension is similar to that introduced
on the 1994

It is a multi-link structure featur-

ing two lower arms by which an ideal virtual kingpin

Compression lower arm

axis is formed. In addition, the upper arms have
been raised above the tire level to improve both
directional stability and ride.

CONSTRUCTION

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.
