Mystery tilting trike.
Mystery claim their tilting independant suspension trike design is a first. I would disagree with that, but it is however high tech in what is
otherwise a very low tech area i.e. Harley custom trikes.
As I understand it, they use air shocks, but in one of the pics, I think I can see link rods, so, the burning question is, are they using compressed
air or levers to actuate the tilting effect? Mystery link.
Cheers, Rorty.

Hi! When I saw this picture, I started to wonder where I have seen a diff Like that for sale on the internet... Is there anyone knowing who´s selling
a simular diff (just the diff)? I hope there´s a LSD version too!!

The diff itself is nothing special looking. You could achieve the same with an open/slippy diff in a machined or spun casing with a suitably sized
timing pulley.
I've made similar diffs except with sprockets instead of a timing pulley.
Just looking through my supplier's stuff, you can get timing pulleys in pitches from 2.5mm to 20mm and belt widths between 8mm and 50mm up to
400mm diameter. There are some pretty heavy duty belts around these days too.
Cheers, Rorty.

OK!! Then I´ll do one myself. Have you some pictures on the differentials you have made??
The Formula SAE student cars have made very nice diffs!!

Rorty,
Do you think there are any components inside the horizontal cylinder carrying the disk brake and the sproket for the toothed belt?
I guess I mean, is there really a diff in there, or is lt a bike rear end "stretched" in the horizontal direction? I suspect the latter
because it would be awfully clever to stick a diff in space that small, with a "casing" that rotates.
Cheers

Oh, how fast can a speeding pullet go?

There's a thread in the Bec or Middy forums where I posted some info and a pic of an encased diff. It looks suprisingly similar to the picture
above.
I would imagine there is a diff in there. It could be just a torsion tube, but it's a rather clumsy way of doing it then. A typical encased diff
is only about 120mm diameter.
A diff from a quad would be substantially less.
Cheers, Rorty.

Might this be of some use?

It's only rated at 14hp, but who knows? Once something breaks, you'd know what to reengineer.
