autogyro's Transmission Concept

[xpensive]

But seriously guys, the "gearless" and "stepless" transmission, is a classic fantasy by many an armchair-engineer.

Reality is that conveying torque by friction between rolling elements are rather futile, which soon becomes evident when you start cracking numbers and surface-pressures goes off the clock. It works pretty well with small torques though, like my kid's RC-cars, they all have steelball-differentials.

But as usual, if you ditch the maths, you be fine in your armchair.

They are all still using a layshaft geartrain concept that is over a century out of date.
Shame realy.

What type of transmission configuration would you suggest instead? Preferably some concept that is equally compact, light and efficient? It's hard to believe that you could come up with a transmission that provides a better overall combination of weight, package size and efficiency than the typical 3 shaft, transverse, spur gear/dog ring, dry sumped, dual clutched, F1 gearbox.

I'm interested in hearing your better idea.

oh no! You just opened up a can of worms here..

..when there's still a perfectly good can open over there

Well now.
I do have an ESERU Electric Shift Energy Recovery Unit, which is a 7 speed F1 gearbox.
It has NO clutch and the geartrain goes into a cube of 120mm.
It transmits torque to the rear wheels during upshifts and does away with the need for any clutch completely.
(12cm less at least on this years Forth Bridge cars)
It is ALSO a combined electrical energy recovery and application system.

Oh yes and it has been looked at by a number of the top F1 engineers including Williams (Wirth want to see it in March) and they all state that it needs to be developed. I will say that again, it needs to be developed!!!!!!
One of the reasons Willams has dropped their CVT based Kers system is because they have had sight of it, although they will of course blame FOTAs ban, to retain their reputation. CVTs and TVTs are a dead end in performance application.

News release ends.

My system is a stepped gearbox and NOT a CVT.
I agree totaly with your reference, CVTs are to inefficient for performance use.
A pity Patrick Head did not realise this earlier.
The geartrain in my ESERU, becomes ONE component rotating in ONE bearing in top gear, which is the lowest possible toque loss EVER in a transmission.
There is NO clutch, mechanical, hydrolic or electro magnetic.
The system can also be configured for road application as a far superior Hybrid transmission in a combination of series parallel and even full electric form.
Makes current thinking on such systems totaly obsolete.
Guess what, vested interest is preventing its use!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Please do not ask me how it works, unless under a non disclosure agreement or £4 million up front.

I'll sign an NDA to find out more (I run a web business so no vested interest or ability to take this elsewhere, just curious). I'm sure a few other hopefully more technically capable people would as well.

Maybe this has been raised before, but why not just patent the thing?

I am retired and will not bother to fully patent the system until I find a suitable partner to run a full study and develop it.
I have always found NDAs to be sufficient in the past.
If FITech can convince me of a method to achieve NDAs over the web, I would be happy to send copies of the schematic and operating description to anyone interested.

I agree, it fits the character traits of almost all the FI Engineers I have ever met.
It is a pity the current ones are laboring around in a ring fenced and controlled environment that prevents any innovation.
Well boring.

My system is...........

To be honest, i don't care about your system & how many channels it can record at once; its over my head completely to comment on it. but it doesn't belong in this thread. that was my point.

Alas, I was too late, the can has been opened in here..

Worry not Fil, Ciro will keep things in line.
Of you go, back to obsolescence and great long racing trains.

My god.

This crap is STILL going?

We've already established that your idea is baseless, it is a construct in your mind only, no practical tests, no calcualtions, no hard data, and indeed no facts at all only your say so. And is therefore worth precisely nothing at the moment.

Please do not ask me how it works, unless under a non disclosure agreement or £4 million up front.

Is this a joke? If it is well done, I feel foolish for missing it. If not then who the --- do you think you are?

This is a forum, noone is going to pay any money and you must know this. Therefore I simply cannot fathom a reason for you to type the sentence above.

If FITech can convince me of a method to achieve NDAs over the web, I would be happy to send copies of the schematic and operating description to anyone interested.

Not the forums job, it's a contract agreement between you and the specific user. You can get a ready made generic 'fill in the blanks' agreements out there, you just need to make sure it conforms to the law. They need to be printed signed, and signed by a witness. Then they are legally binding.


EDIT: I can't believe i've been sucked back in to posting in such a blatantly bullshit thread.

[autogyro]

We shall see.
Annoying innit.

[Giblet]

Only if your read and respond to it, otherwise it's not happening at all, and is of no consequence.

[autogyro]

Exactly
Annoying
It must be having to quantify everything to keep your peace of mind.
Takes all sorts.
