autogyro's Transmission Concept

[autogyro]

AUTOGYRO you are clearly 'desparate to get you technology taken up by somebody... anybody.

I've already responded on an other thread that using multiple planetary sets, each with motors etc is covered by numeroius prior patents.

And in response to your comment that the Zeroshift Technology was a scam..... it was NOT!

The original 2004 technology used flexible arms fitted into slots in the top of each bullet. This was later replaced in 2006/2007 with the bullets fixed to the Underside of each Actuator ring.

The technology would work but suffers from some engineering issues which I pointed out to them in 2004. Namely forces acting against the bullets and their slide channels etc.

There was also no hope whatsoever that the ZSL technology could possibly reduce the size of the gearbox which was their original claims.

The problem with Zeroshift was that I showed them numerous layouts and mechanisms that would hae aload them to circumvent issues with their previous mechanisms. However it's clear that William Martin was obsessed with getting 'his' invention recognised. In this he failed from a Business objective and didn't recognise a Gift Horse when it was shown to him.

I am not desperate to do anything.
In fact Ian you have again underlined the reasons why I hate the bloody industry.
All trick shifts that retain a stepped layshaft geartrain are scams.
The need for a shift speed faster than the conventional baulk ring or dog ring system in a road car is a waste of effort.
It is the gearing that needs changing to meet todays demands for energy efficiency.
F1 is simply a marketing exercise living in its own regulated world completely remote from the real one.
Zeroshift was primarily a marketing operation selling snake oil.
The shift ideas covered by zeroshift and the others originate from just after WW2, I talked at length with Alec Stokes about them in the 70s. All the mechanism geometries mentioned were covered and some not yet even in the public sphere.
It is all ancient history Ian.
My system is well documented and has a paper trail going back 40 years.

The future is Electric Racing

The question now is, do electric cars benefit from a gearbox?

Of course it has been tried but not with any success as yet.

Anyone out there want to invest in an electric car development and a team?

Autogyro in answer to your question re gearboxes and electric cars....

The answer is yes, Electric motors do indeed benefit from utilising a gearbox with between 2-4 ratios (depending on application).

The main issue is Optimum Torque versus Power curve. As everyone knows you need a great deal of torque when starting off (particularly on a hill start) whereas at say motorway speeds you need an effective 'overdrive' capability.

So an Electric vehicle needs a high-torque/low stall capability at starting speeds which is at odds with medium to high-speed requirements.

The minimum requirements for efficiency for the likes of the Tesla car is 2 gears; one for low-speed, high torque requirements then into higher gear for medium to high speed.

There is plenty of research that shows that an electric vehicle can gain 10%-15% or more efficiency using multi-ratio gearbox inline with Electric motor(s).

I know Ian.
Unfortunately many in the electric vehicle field do not as yet see the need for a gearbox.
Hewland did and it is why they designed a two speed gearbox for the formulec Merc/Petronas car for Formula E.
Formula E used the formulec to establish the recently released regulations for 2014 and the car was based on the suggestions I placed before the FIA in 2010.
Hewland also consulted me on the need for a gearbox gearbox along with ideas from my ESERU.
Tesla tried a gearbox originaly in their road car but their unit only lasted for 2000 miles so it was removed.
Conventional geartrains are not suitable for the flat torque curve of an electric prime mover.

I know of Porshe road electric conversions that have destroyed the gearbox in less than 500 miles when the motor simply replaces the ICE.
Layshaft, whether dual clutch/shaft, bells whistles or what ever just doesnt cut it far to ancient.

[autogyro]

Of course my ESERU is ideal for Formula E but I cannot self promote on that thread they will ban me.
I have a major single seater manufacturer very interested in building championship winning cars with me.
All I need is the F1 level of budget needed.
I badly need a marketing guru of the top level, the technology is not a problem.
Dont get me wrong I am not bothered one way or the other being retired.
It will be a shame if the project does not happen though.

Hi Auto, can you expand on this please? What are the specific transmissions issues arising from a flat torque compared to IC torque?

Above is a presentation PDF from your friends and mine 'zerothingy'.

They took their thinking directly from certain 'autogyro' talks with others.

They are very close with the 'sweet spot' but no cigar.
Of course this is a conventional layshaft geartrain and has no chance of reliability or a decent working life in anything other than an electric bicycle, where it would be way to heavy.

Plenty of manufacturers trying multi speed gearboxes in EVs Richard check it out.
They finaly listened to my argument against the electric geeks and their continual anti gearbox stance.
All they need now is the 'right' gearbox.
Marketing bumf again, wish I had the guy they use.

Sorry but I am not prepared to give away the answers to improved EV performance Richard.
You will have to join the que.

It seems that non of my posts are being allowed on the formula E thread.
Instead the thread has degenerated yet again into a motor head's bashing of green issues.
Nothing changes in dinosaur land then.
