new suspension systems

Post

The next pictures shows a demonstration of my work

The last picture is a new concept of formula one monoshock:
V-Monoshock with pushrods and integrated stabilisators. (stabilisators not displayed)
The new concept of TRD damper is on this image not showed

this is a front suspension for IRL with springstabilisator

IRL rear suspension

and here is a new concept of formula one monoshock

whats so special about the new concept?

Nice drawings. However, the IRL front seems to have superflous parts making it unneccesarily complex.
The IRL rear; How is the motion supposed to be transferred into the shock/spring?
The new concept F1 momoshock looks like it will promote body roll, can't be very ideal on a F1.

Referring to the 1st. system displayed:

The only difference I see from a conventional system is a shock absorber between the two wheels. It would add to the stabilizing bar an effect that would depend on the speed of the bump or rebound (if it works both ways). It would have no effect on the pitching of the car in acceleration or braking. Then:

1) It would add a strange behaviour in circuit bumps, making the responsiveness of the suspension vary with speed and bump profile;

2) It doesn't help avoiding pitch under braking or acceleration, one of the most important aero problems to avoid by suspension design.

So, I can't imagine what good it would be. Maybe the author could enlighten us????

Difference of the new V-Monoshock is a pushrod with integrated stabilisator (stabilisator is into the pushrod-on drawing is stabilisator not showed)and a new Through Rod Damper (not showed) for two springs.

This is a design, that is now not optimal for aerodynamic. That is not a Problem. The design of monoshock is very variable for some aerodynamic concepts. Work of V-Monoshock is inverse.

those are some sweet renderings, however looking at your design, it looks like there is a completely solid connection between the left and right pushrod. It looks like the force from one pushrod on one side would be mostly exerted onto the other pushrod, rather than a spring or a shock absorber. I understand what you are trying to do here, the concent is quite nice, but perhaps you need to rethink some of the angles in the motion. If you think about it, all this concept is really doing is dividing the shock to 3 springs rather than just 2. I wonder if you have ever seen the rear suspension in a Nissan R390 GTR, its quite unigue in Lemans and in cars in general. check it out when you have the time.

What would be the improvement of this monoshock design over the one say, on a Formula Renault car? The idea of this is basically the same as that of Formula Renault 1600/2000, but their shock is mounted on a rigid point on the chassis. I can see that this way will reduce shock bending on the extremity of the rolling situation, but with the shock being on a moving mouting, it would definitely compromise suspension rigidity as you are feeding loads into a mount on what effectively is 2 plates....

that IRL rear looks unneccessarily complex, while the other seems to be just a damped anti roll bar.

BTW, what is so special about R390's rear suspension, from what I have seen it seems to be just regular pushrod with inboard damper....

The design of V-Monoshock is now not complete. The stabilising component is a hydraulic cylinder. And solution of a TRD damper is not succesfull completed. I hope, i can later show some drawings of completed design of this monoshock (now not patentet).

The two pushrods are telescopical. This is not shown on these images. If one pushrod moves up, the second pushrod moves up too, because the pushrods are joined together with a hydraulic system (with pipes, acumulators, one-way ventils.....). The relation between forces on the first and second pushrod is depended on the elasticity of the acumulators. The hydraulic system consequently works as a stabilisator with torsional spring.

With regards to 'the F1 mono-shock' concept to me it seems that there are more, and heavier parts - so in my eyes the inertia will be greater than the old school design.

Furthermore sliders are not cool...

MAte !!! Work is good!!))

But IRL has pull susp)) (not push)

So next thing that i wish to you is ti be more simple....
Sure everything will be cool

peter skorvaga,

Most F1 cars curently use torsion springs, instead of helical compression springs, because they are easier to package and easier to manufacture.

peter skorvaga,

You have my congratulations for putting your ideas out there for public scrutiny. As you're now probably aware, everyone on this forum considers themselves a suspension expert (myself included). But that's what makes it fun, right?

Nice job with the solid modelling too. You have way too much free time!
