DESCRIPTION

The
front

The

spIndle
IS
Installed

on
the

JOInt
IS
attached
to
the
lower

part
of

the

spIndle
The
ball

JOInt
and
the
transverse

lInk
lower
lInk

are
connected
and

they
are

fitted
to
the

suspensIOn
member

through
a

mechanism

IS
bUIlt
In
the

seat
fitted
to
the

upper

of
the

piston
rod
and

spring
seat
welded
to
the

caSIng
These

components
assembled
to

a

SIngle

are
fitted
to
the

adopted
In
thiS

suspensIOn
system
IS
used

so
that
the

Thus
thiS

suspensIOn
