COLLAPSIBLE
STEERING

The

collapsible
steering
column
is

designed
so
that

compression
occurs
when
the
vehicle
is
involved
in
a

head
on

collision
See

Fig
K
13

Two
forces
can
be
considered
when
a
collision
of
this

type
takes

place
These

being
the

primary
force
in
which
the

forward
motion
of
the
car
is

suddenly
halted
and
the

secondary

force

as
the
driver
continues
in

a
forward
direction
onto
the

steering
wheel

and
column
The

collapsible
column
is

designed

so
that
it
does
not
move
to
the
rear
i
e
into
the

driving
com

partment
when

the

primary
force
or
forward

motion
of
the
car

is

suddenly
halted
When
the

secondary
force
takes

place
as

the
driver
is
thrown
forward

the
column

jacket
gradually

collapses
and

partially
absorbs
the
amount
of

impact

The

collapsible

type
of
column
is
no
more

susceptible
to

damage
than
an

ordinary
column
when
it

is
installed
in
the

vehicle
however
when
a

collapsible
column

is
removed
it
must

be

carefully
handled
A

sharp
blow
on
the
end
of
the
shaft
or

gear
change
levers

dropping
or

leaning
on

the

assembly
can

cause

the
column

jacket
to
bend

particularly
at
the
bellows

part
which
absorbs
the
shock

The

steering
movement
is
transmitted

by
the

lower
shaft

and

upper
tube
The
lower
shaft
exterior
and

upper
tube

interior
are

tightly
fitted

together
with
four

plastic

pins
com

pletely

eliminating

any
gap

When
a
collision
occurs
the

plastic
pins
shear

and
the
lower

shaft
enters

the

upper
tube
this
action
will
cause
the
shaft
end

to

spread
and
the
lower
shaft
cannot

then
be
withdrawn
unless

an

extremely
high
load
is

applied

The
shaft
is

prevented
from

moving
towards
the
drivers

compartment
when
the

primary
force

takes

place
i

e
when

the
forward
motion
of
the
vehicle
is

suddenly
halted

by
the

three

stoppers
on

the

jacket
tube
The

steering
lock
collar

mounted
to
the
shaft
contacts

the
stoppers
and

prevents
a
rear

ward
movement

A
part
of

the

jacket
tube
is

specially
formed
to
act
as
an

energy
absorbing

part
of
the

collapsible

steering
The

upper

and
lower

guide
tubes

joined
with

polyacetal
resin
are

inserted

into
the
mesh
tube
so
that

energy
generated
by
a

collision
can

be
absorbed
as

smoothly
as

possible
with
a

low
load

The

steering
column

clamp
shown
in

Fig
K
14
is
secured

to

the

jacket
tube
and

body
by
bolts
with
two
aluminium

slidings
blocks
set
to
the

body
by
plastic
pins
An

impact
from

the
drivers
side
causes

the

plastic
pins
to
shear

and
leave
the

sliding
block
in
the
column

clamp
side

allowing
the

clamp
to

move
with
the

jacket
as
