Let's Talk Cyclecars

I'm afraid we would end up wearing a 2 seater as well.

 

I have ongoing daydreams about a rideable reverse trike. The best iterations tilt.

 

I guess you have seen these

I'd ride that. Mike

 

For all you Rumpler fans . . .

Too complex. I want to ride not spend the rest of my life ironing out the bugs.

 

Loved that movie. Thanks for the link. So what was the W6 engine?

 

I've seen the NerAcar bike and there is one for sale right now on BAT or Pre-War-Cars.
I have never seen the trike before. Good find Bob.

 

Well Fredvv44, sadly I've not been able to find any photos/drawings/patents for the W6 so far, but did find the following description of the drivetrain:
"The car featured a Siemens and Halske-built 2,580 cc (157 cu in) overhead valve W6 engine, with three banks of paired cylinders, all working on a common crankshaft. Producing 27 kW (36 hp), it was mounted just ahead of the rear axle. The engine, transmission, and final drive were ***embled together and installed as a unit. The Rumpler-invented rear swing axles were suspended by trailing leaf springs, while the front beam axle was suspended by leading leaf springs."
I did however come across these patents for automobils . . .

Thanks j hansen!!

 

If I'm not mistaken, Tatra differentials worked on that principle.

I like the idea of the friction sliding disc drive. Too bad they couldn't develop it further. Usually dampness was it's enemy.

 

Bob, doesn't Snapper lawnmower stiff use a disc drive? Seems to have worked pretty good for years.

 

And my "8 speed"snowblower.

 

Ah! "One of Rum[p]ler’s ***istants during that project was Hans Ledwinka, who would become the chief designer for the company that became known as Tatra after the mountain range."

Interesting website, that.

 

GWK were the best-known proponents of friction drive:

 

These pics are different to the first one I posted,different models??

 

The sliding disc had a limited ratio range and slipped too easily. If you left it in gear when parked you got a flat spot on the driven wheel.

 

found this W3 MotoGuzzi engine in my archives.

 

Anzani W3, original ( in the Shuttleworth Collection) and a brand new working replica from Pioneer Aviator, perhaps just right for your next GN or Morganesque trike project!

 

The principle didn't hold up in automotive applications.....

 

Bob, I think I've read on AACA that the company that made discs for cars like the Metz still is in business. May have been some kind of compressed paper product? Every car company was trying to do the same thing in different ways, some worked.
