CHASSIS

DESCRIPTION

The

front

suspension
is
of
a
strut

lype
The
shock

absurber

and

spindle
are
combined
to
a

single
unit
which

is

supported
by
the
coil

spring
at
the

upper
end
aod

by

the

transverse
link
at
the
lower
end

The

spindle
is
ins
tailed
on
the
bottom
of
the
strut

outer

casing
by
means
of

welding

A
ball

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

rubber

bushing
The

shock
absorber
mechanism

is
built
in
the

strut
outer

casing
A

coil

spring
is

applied

between
the

upper
spring
seat
filled
to
the

upper
end

of

the

piston
rod
and

spring
seat
welded
to
the
outer

casing

These

components
assembled

to
a

single
unit
are
fitted
tu
the
chassis

frame
at
their

upper

part
through
the
thrust

bearing
Moreover
the

transverse
link

supports
the
overall

forward
and
backward
strut

movements

by
means
of
the

tension
rod

filled
to

the
chassis
frame

through
a

rubber

bushing
The

rubber

bushing
adopts
a

non
linear

shape

with
which
the
forward
and

rearward

rigidities
are

changed
The

torsion
bar

type
stabilizer

adopted
in
this

suspension
system
is
used
so
that
the

strut
maintains

connection

between
both
side
struts

Thus
this

suspension
mechanism
absorbs

shocks

toward
all

directions
into
the

chassis

effectively
and

efficiently
the
tension
rod
absorbs

forward
and
backward

shocks
the
strut

absorbs
vertical

shock
and
the

transverse
link

absorbs
shock

applied
toward

sideway
