Thread: Independent Suspension Design

All your airlines and bags should be available from any decent truck spares shop,, I'd use Festo fittings and line, they will also carry the ride height gear you will need.
What compressor are you running?
Having read the thread, did I miss the part where you keep air in the bags? external compressor into schrader? no cross linking?
You can buy small festo pressure guages that will sit quite happily in the system.
Though, to be honest I think a ride height valve way over the top for this,,

slug_burner,
Had a good read of the trailer laws just now. Stop/tail max distance in from out side of vehicle to edge of light 400mm, this goes for the indicator as well. No higher than 1500mm & no lower than 350mm. Your were spot on.

Mine are well inside these on all accounts.

I was confident but thanks for putting drought in my mind, so i had a re-read.

Cheers
David

After I had a look, I thought that your indicators were the only ones of concern on the 400mm issue. I can't estimate where the extreme outer of your trailer will be. I'm glad your ok, sorry if it caused you undue concern.

Trailer passed rego
Now to start building the nose of the camper, i have 12 working days to have this thing ready for Fraser Isl.

Yeah, don't like it. Fair enough you built it and designed it yourself, but sometimes there are reasons other systems are so widely and commonly used haha.

Goodluck regardless.

Shamo,

What are the reasons other designs are widely used?

I understand that there are people everywhere that are not, for what ever reason able to design & build items that they wish to have. That is where a shop comes into play. Then there are people in this club that are happy to share there builds with us, so that they may inspire other members to get the confidents to at the least have a go, at anything.

Just lucky for me i like it! And many other do too!

Cheers
David

Yes, the commonly used designs are easy to copy and build, and in general show no new initiative in how they go together. Also, you have the sheep factor - because someone does it one way, everyone follows. Sort of sounds like you drive a Toyota...

I think the central spine will be very strong - a lot stronger than conventional designs. The only part of the suspension I see a potential for an issue is how the tyres will wear, but David has gone over that before and he can manage this with the airbags.

Then there's the satisfaction in designing and building something yourself.

Most others comments on this build have been constructive, and I'm not sure why you are just hanging it on him because you don't like it....

Keep the criticism constructive mate, you only make yourself look like a dill openly laughing at someone like that, and it's not considered good form on a forum such as this that holds such high standards.

I am looking forward to see how it all comes out and how it performs in he real world.

I would be a lot more positive about this build had the swingarms pivoted the other way or been paired up in a double-wishbone type design. I suspect others feel the same.

This design was used on the Corvairs.


It is famous for all the wrong reasons: http://en.wikipedia.org/wiki/Unsafe_...rty_Corvair.22
