The NAPAC
standard
test (a
standard
for after
market
products
in Japan)
has been
done. A
screwing
test was
done to
check the
operation
of steering
wheel to
radial
power.
There was
not any
change
in the
shape after
being pounded
by dead
loads of
29.7kg.m
(291N.m).
Moreover,
there was
not any
change
in the
shape after
a bending
test of
dead loads
of 19.8kg.m
(194N.m)
in order
to examine
the effect
when a
driver
impacts
the top
of the
steering
wheel in
an accident.
According
to the
results
of these
tests,
although
the bending
test caused
the permanent
transformation,
it is possible
to tilt
up. Furthermore,
the screwing
test based
on regulation
loads did
not cause
any problems.
Also, in
order to
know the
limitation
of tilting
up, bending
loads 38kg.m
(372N.m)
was given,
although
it stretched
a lot,
it was
not broken
and it
is still
possible
to operate.
Moreover,
30,000
times of
tilting
up and
tilting
down operation
in order
to check
the endurance
were down
in our
factory.
We confirmed
that it
is possible
to operate
30,000
times without
changing
parts although
it is necessary
to smooth
the parts
with oil
during
the test. |
