1. The suspension consists of a pair of lateral arms
(upper arm (2) and lower arm (3)) mounted on
the suspension crossmember (1) and trailing
arm (5). The lateral arms and axle housing (4) are
connected by the ball joints. The axle housing,
that is, the rear wheel can rotate about the
. -.-
centerline of the upper and lower arm ball joints
as a steering axis.
The trailing arm and axle housing are rigidly
connected.
The suspension geometry is basically deter-
mined by the layout of these components.
2. The trailing arm also has a middle joint provided closer to
the suspension crossmember. As it is connected by pin (7)
that runs through it vertically, parts (A) and (B) can rotate
relative to the pin. The insertion of rubber body (8) creates a
spring constant in the direction of rotation.
