STEERING

DESCRIPTION

The

steering
system
consists

of

recirculating
ball

type

gear
box

and

parallelogram
linkage

These

systems
give
good

response
light
handling
and

utmost
durability
Moreover
the

steering
linkage
is

equipped
with
a
torsion

rubber

system
idler
arm
which

absorbs
shock
from
the

wheel

Check
the
lubricant
of

gear
box

every
10
000

km
6
000
miles
and

replenish
recommended
oil
as

required

The

steering
linkage
should
be

greased
up
with
wheel

bearing
grease
every
50
000
km
30
000
miles

All

necessary
service

procedures
for
the

steering

DESCRIPTION

This
column
is

designed
to
be

compressed
under
an

impact
When

an
automobile
is

being
driven
the
forward

movements
of
the

automobile
and
the
driver
constitute
a

form
of

energy
or

force
When
the
automobile
is
involved

in
a

head
on
collision
the

primary
force
forward
move

ment
of
the
car
is

suddenly
halted
while

the

secondary

force
the

driver
continues
in

the
forward
direction
A

severe
collision

generally
involves
these
two
forces

primary
and

secondary
The

secondary
impact
occurs

when
the
driver
thrusts
forward
onto
the

steering
wheel

and
column

The

collapsible
column
is

designed
to
absorb

primary

and

secondary
forces
to
the

extent
that

the

severity
of
the

secondary
impact
is

reduced

thereby
reducing
the
tenden
cy
to
move
rearward
into
the
driver
s

compartment
A

split
second
later
when
the
driver
is
thrown
forward
the

secondary

impact
this

energy
is
also

partially
absorbed

by
contraction
characteristics
of
the
column

When
the

collapsible
column
is

installed
in
a

car
it
is

no
more

susceptible
to

damage
than
an

ordinary
column

however
when
the
column
is
removed

special
care
is

required
in

handling
the

assembly
When
the

column
is

removed
from
the

car
such
actions
as
a

sharp
blow

on
the

end
of
the

steering
shaft

or
shift
levers

leaning
on
the

column

assembly
or

dropping
of

the

assembly
could
bend

the

steering
column

jacket
especially
the
bellows

part

which
absorbs
the

energy
