o.k. Brian let's see if we can salvage something from this thread
you started out with saying :
Well, I was thinking of the adjustment that we see the driver doing when he moves his hand to the side of the cockpit.
That let me come to the conclusion, that you were talking about the systems used in F1, and I responded to that.
You did no liked it, and you had set your mind, that the systems used in F1 have to be a balance bar adjustment only and nothing else.
Some others commented about some of the details of the Ferrari system, mentioned during Spygate.
I responded, by showing a diagram, which shows, what effects such an system would have on the brake bias of a car.
You didn't liked it, accused me of hand waving and insisted, that these system have to be balance bar adjustments, or adjustments which maintained a fixed brake bias front-rear at all time.
Now, this point is perhaps open to debate, but I accept that you were mainly interested in mechanical solution which only alters the balance bar setting, or the effects this has on brake bias ( discrete change from one fixed ratio to another) ,
but this has perhaps nothing to do with the systems, that are in use in F1, unless you can show photos or mentioning of such a specific system. The reason I ask you to define "Brake Bias" was not to hassle you, but you may want to accept, that it perhaps means different things to different people.
And just because some journalist or driver is talking about a rapid brake balance adjuster, that does not in itself mean, that the only way to do it, is the one you have set your mind too.
About your general way to proceed in discussions on here is, that on one hand you state:
I never meant to imply that I have any detailed knowledge of the subject other then what experience I have from commercially available parts. I made an effort to keep the thread on point so as to extract a mechanical solution that I can appreciate.
but on the other hand, you seem to feel qualified and confident in your knowledge to state, in a matter of fact tone:
2) Losing 'part of the force coming from the pedal' is not acceptable with the forces required to stop a F1 car.
This is not acceptable to F1 designers or in my personal applications.
How do you know that, without detailed knowledge? As you shout into the forrest, so it will come back to you. Don't be surprised that people can't be bothered to explain things to you, when you have already made up your mind.
Furthermore, you stated, that you were just interested to understand the general concept, and how such a system could
possibly look like.
Now you want a full manufacturing drawing, best with tolerances and FEA results, that's perhaps a bit of an ask on a forum such as this.
But even if someone would be kind enough to take up your challenges, how could he do so, without knowing the parameters you have in mind? The only parameter you mentioned so far is fast adjustment speed < 1s.
But how much quick/rapid adjustment do you need/want? +/- 1%, 2% 5% 10%, that would have a influence on the chosen design, the width/travel range of the shuttle for example.
Now you come out and say, it has to fit inside your AP/Tilton pedal etc., that wasn't mentioned before.
So if you really would like a concrete answer, you would need to ask some more concrete questions, define your design parameters how much % +/- adjustment do you want, whats your total adjustment range needed and give some of your constrains.
Otherwise, someone may purpose a design, and you turn around and say, yes but there is my throttle pedal/cable or whatever other constrain you didn't mentioned before, which means that person has just wasted his time trying to help you, but you are still not happy/satisfied. I'm sure most people wont come back for a second time.
Mind about the second solution, I posted, that wasn't meant as a joke, it's probably the fastest and simplest way to build and to integrate with what you have, only need to make some modifications to your Knob / driver interface.
If you have a concrete application in mind you will need to tell us the parameters, otherwise you are the one doing a lot of hand waving, and this thread will go nowhere.
Mind about it for a bit, most people are kind enough to help, if ask nicely.
Merry Christmas Brian
