CLASS®, or Compressible Liquid Adaptive Suspension System

[davidbrady]

These guys offer a twist on ping tanks (auxilliary reservoirs). They tune the suspension resonant frequency and damping in real time by proportionally altering a rate valve between the suspension and the ping tank. The other twist is the use of a "compressible liquid". Seems a little light on details... It reminds me of the old Citroen hydropneumatic suspension, but that design used nitrogen pressurized spheres for progressive compressibility. No such gas in this system.

Boy, talk about adding some class to the site!! Ok, ok, SOMEBODY had to say it!


I wonder if you could couple the leveling system into this, level and the pressurize both sides of the struts to achieve a stable platform? Seems plausible.

John,

What do you suppose this marvelous new liquid material that compresses to the degree required is. It's undoubtedly some sort of carbon nano tube fortified liquid, right? I think the marketing term for it is Snake Oil! LOL

[Arcticdude]

Given the level of sophistication of the class site, I'd say snake oil may be giving credit where it isn't due!!

Of course it does state : "Eliminates "head-toss" caused by oversized sway bars" That should be right up your alley. LOL Maybe they're reading the forum!!




In reading an installation manual, they state "locate the container of Silicone fluid".


Of course, nobody ever states HOW compressible the fluid is!

John, how do you think I found the site? In my spare time you can often find me sitting at my computer practicing my Ctrl-Shift-T's and googling "head tossing sway bars"! LOL

Seriously, I think the only "compressibility" they're getting is the tin-canning of their ultra thin walled hydraulic cylinders, which means their suspension travel tuning goes gently from None to Next-to-None. :-)

[Arcticdude]

Certainly those highly sophisticated ECU's and "rate valves" would offer supreme and near instantaneous adjustability and control over the most extreme of terrain in even the heaviest and unwieldliest vehicles!!

[davidbrady]

After a little more research I'm learning that this system is legit, but it doesn't rely on 'compressible liquid'; seems that's the marketing department taking liberties. It does use a pressurized gas, so I suppose one could call it a hydropneumatic system like Citroen's, but in this case it's almost an active suspension (yikes, another marketing term)! Word is that it's not yet heavy duty enough for Class 8 vehicles.

All the current versions are on 1.5 ton or less vehicles.
