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

CHASSIS

The

construction
of
the

steering
column
is

as
such
that

the
lower
shaft

is
fitted
into
the

upper
tube
when
a

compressing
force
is

applied
to
the
lower

shaft

Steering
torque
is
transmitted

by
the
lower
shaft

and

upper
tube
The
lower
shaft

adopts
a

special
shape
a

circle
with
two

straight
cut

edges
and
the

upper
tube

interior
is

tightly
fitted

against
the

lower
shaft
exterior

toward
the

entire
area
In
addition
four

plastic
pins

completely
eliminate

between
the
lower

and

When

the

and
the

cannot

runs

in
three

places

which
allows

the

and
thus

prevented

Note
In
no
event
should
an

impact
or

large
power
be

applied
to
the
shaft

with
a
hammer
or
other
matter

during
disassembly
or
