Time to share some
secrets: My 6-link (long)

3:53
AM 4/10/2002

Hi all !
As you probably know I´ve been
working on a new 6-link suspension based on the design of
Stingys‘ car. (Stingy, thanks for sharing the pics of your
6-link)

After taking some measurements, I started to construct the
different parts on ACAD.
The idea was to make the whole
system out of high quality aluminum, so I manufactured a part
proposed for testing to confirm my calculations.

Well, this was my „testing setup“. Although not complicated
it was enough to get an idea how the part will handle the
forces.

As you can see, the hole got elongated before the part
collapsed.....

After the hole was elongated the part started to bend; that
actually gave me an idea of the distance between the hole and
the area which would fail first.
But due to manufacturing
problems I couldn´t make the parts out of aluminum. Bending
the profile to the desired shape with help of a machine caused
little stress cracks in the surface.

This pic shows the part before bending it to the desired
shape.

So the only way to go was to use stainless steel.
I had
to change all my manufacturing drawings but after making a
test run on the machine it payed off. No stress cracks
anymore, the weight difference wasn´t as big as expected
because I could use a thinner plate due to the higher strength
of stainless steel.
After cutting out the plates a colleque
of mine bend them on the CNC bending machine, then all the
parts were reinfored at the desired areas by welding in/on
some additional plates.

Then I painted them, manufactured the strut rods, zinc
plated them and assembled the whole system.

Looks sharp, doesn´t it?

Here are some more pics..

Maybe I´ll start a little production series after testing
the system under real circumstances. I hope you all understand
that I can´t share the construction drawings on the forum.
There was simply to much time, money and work
included.
Nevertheless, if you have any qustions left feel
free to ask me whatever you want, I´ll try to serve you as
good as I can.

The rotation points of the strutrods are optimized, which
means that there´s no camber change at all. The secret here is
to use equal length strutrods.
The balljoints are all high
quality SKF bearings which are teflon lined, which gives
maintanancefree longlivety of these links.
Hope you´ve
enjoyed my little story,

Markus from Austria

Looks really good Markus. I like the pit with
the ceramic tile. Also nice job on the finish of the frame and
rearend. At first I thought you were running coil overs
without the springs attached. It wouldn't be hard to convert
to coil overs?
Have a nice
day

One thing occured me while looking at the pics,
you're not running rear sway bar at all. I also noticed that
the 6-link trailing arm mounting point covers the sway bar
mounting, so it is not possible use rear sway bar with the
6-link set
up?
