hydraulic suspension

[darksag3x]

could creuat's hydraulic suspension tech be applied to grand prix cars? would it result in a detriment to or improvement in handling/grip?

Very interesting - I have not had time to read it all. But it looks like some F1 systems achieve similar results (via a different route) with their multiple spring & damper systems.

As ever, the answer is probably in the detail of the design for the whole car and F1 engineers are getting their systems packaged as they want them and doing the job they need. Why design the car around the suspension?

[manchild]

Any passive suspension system can be applied on F1 car. I presume that at least one pump would be necessary to keep this one under pressure and that would be illegal. Even shocks with fluid that changes its viscosity depending on electrical current are prohibited.

Could there be a gain in stability/handling in corners if 4 chambers of 2 shock absorbers on one axle would be asymmetrically connected in a way that right piston is pushing the fluid/gas from above to below piston of left shock absorber.

When right shock absorber is under pressure it would move the fluid/gas below piston in left shock absorber and prevent left spring from pushing left suspension down – causing more horizontal position of the car?

Force affecting right suspension could partially (via pipeline) affect left suspension too because left shock absorber would contract and reduce/prevent left spring from opening up left suspension.

I’m thinking on X pipeline...


System opposite to this one – parallel/symmetrical instead of symmetrical pipeline I see as potentially interesting for off road vehicles.

Audi already have a system like that

dynamic body control or something similar, too lazy to find a link

Manchild, from the description I'm assuming the left hydraulic cylinder is connected to the left front suspension, and the right cylinder to the right front. Nice concept, but isn't that basically a hydraulic representation of an anti-roll system? The same job can be done with a conventional mechanical system.
But if that left cylinder was connected to the left rear suspension, and the right cylinder to the right front (and a second, independant system connecting right rear and left front), then it gets interesting.

I admire your honesty.

You've understood it right. It sure looks like hydraulic anti roll system but those could be real shocks with valves not just pistons.

But if that left cylinder was connected to the left rear suspension, and the right cylinder to the right front (and a second, independent system connecting right rear and left front), then it gets interesting.

Something like giving "hint" to rear wheel what to expect since front wheel has already dealt with bump? I thought about that but I think that slow bumps are less of the problem than stability in high speed corners.

Thats a great pic manchild. Similar to the UWA FSAE car. Compression on one corner is connected to rebound on the other. So roll and pitch are resisted, but one wheel bump is free to occur as required.
