2/23/04 - Here are the axles
that I have been working on. I don’t think that I have any ambitions
to try to market them but any drive line shop should be able to duplicate
these. There is 3” of movement so it should be perfect for adjusting.
They are of course very strong. I think I am in to them for about $1800
CDN plus I supplied the Porsche flange.
This is the most excited I
have been for any single part. The machine shop that I am working with
is going to take the Fiero outboard CV joints and convert them into a
U Joint. They will also have a U Joint on the inboard side mating to the
Porsche axle flange. Between the U Joints will be a splicer axle shaft
with a slip joint in the middle. The set up will be massively strong.
The weak point will be the spline on the Fiero CV. There will be 1.5"
of slip so the wheels can move up and down alot and also out if needed.
And, it might not be that expensive, I'll keep you posted. The shop will
produce as many as we need and can use whatever outboard CV we are using.
This is just an FYI, axles
get broken by torque (twisting power). If an engine makes only 200ftlbs
at the crank, that is multiplied through the tranny and diff. Horsepower
cannot be multiplied. In my Porsche tranny in first gear I would have
2200ftlb going to the axles so roughly 10X the crank torque. That is pretty
remarkable when you think about 2200 lbs on a 1 foot lever. A human can
create the same amount of torque by standing on a 10ft lever. Alot of
people test chassis stiffness with a 10ft long (or longer) piece of tubing
and putting all their weight on it. (in reality the differential splits
that equaly into each axle) Many stock heavy duty pickups can create 10,000ftlbs
at the axle |
