Ratio Zero Transmission

[freebeard]

You already know the first eight and a half minutes:

This Is The World's First Geared CVT and It Will Blow Your Mind - Ratio Zero Transmission -- ?t=513

Prototype to bicycle level, ICE TBD. Clutchless and smoothened.

Very clever.
But perhaps not the cleverest I have seen:

"...The performance of the car was exactly as George had predicted, 100 miles per gallon of petrol at 38 miles per hour...."
In the aerodynamic equivalent of a wheeled outhouse with the door open, on carburetors!

I do hope this gearbox goes somewhere, but am acutely aware of 'aversion to change' atm.

Demise
The car was built in Paris with the gearbox (on the rear axle for forward, neutral and reverse) built in England. It was exhibited at the 1926 Paris Motor Show but only a few were made. General Motors signed a "lucrative" royalty agreement to manufacture the torque converters, giving Constantinesco a $100,000 advance on royalties, but didn't make any, leaving the inventor deeply in debt and the mechanical torque converter sidelined.

General Motors? 1926? Why does that ring a bell?

And now we once again have overhead lines for trucks.

I cant help wondering who it was that wanted everyone burning lots of gas..?

The Constantinesco Torque Converter ended up pulling trains in Romania btw.
It's well worth 'getting it'.
Who can claim 100 mpg of gas at 38 mph (61kph) from a 5.58 hp engine running carbs and probably magnetos..?
Especially with 1924 aerodynamics.
Sounds 'pretty efficient' to me!

I cant help wondering who it was....

There exists an Oregon Times magazine article, but I can't find my copy or a reference online. It was about the demise of electric trains in the Willamette Valley. Their assertion was it was a conspiracy between GM, a rubber company and the company that became Greyhound bus.

It was rubber vs steel wheels.

The pendulum setup is just a simple way of explaining the (brilliant) principle.
If you look at the 1st link you will see very compact cylindrical setups attached to propellers and such.

There's still a lot of 'shaking a weight' going on which probably led to metal fatigue and bearing issues.
Nowadays we have carbon etc fiber and... cough-cough... way better lubricants.

There is also a bit of more recent interest:
