3-Wheel Tilter....Kit Car.....? [Archive]

I was just wondering if anybody knew of any "kits" available for a 3 wheeled tilting vehicle. LOL! I know this is probably the most ridiculous question that has ever been posted in this club, but I thought I would go ahead and ask it anyway.

I understand that the answer to this is 99.9 to 100% NO. But I am wondering if there may be ELEMENTS of this that we can put together somehow.

Really, I guess I'm asking for people to post links here to any sources that you may know of that would present various elements of putting something like this together.

I know.... stupid post. :shup:

Actually, it is a great post. Unfortunately, I must agree on those 99,9% NO :|
Finding suitable parts is hell.

Derwin,

There were plans for one way back in an old Mother Earth Magazine. I don't recall if I still have the plans - I think I sent for them. It was a 2F1R design. Maybe someone else remembers or has it.

Here is the second part of that Mother Earth article:
LEANING TOWARD THE FUTURE:THE 3VG (PART II) (http://www.motherearthnews.com/Green-Transportation/1983-11-01/3VG-Hybrid-Vehicle.aspx)

EDITOR'S NOTE: A detailed information package-which includes
specifications, photographs, and test results-on this vehicle is
available for $20 from 3VG, Mother's Bookshelf, 105 Stoney Mountain
Road, Hendersonville, North Carolina 28791

:whoohoo:dr:ive1)v:i:c:t;o;ry1)

Is someone close enough to those people to check if this is still available?

Edit:If it is too good to be true, it probably is...

"plans" for the 3VG never made it to press. The booklet mentioned in the 2 articles is a history of Shuttleworth''s and other fabricators building and experimenting with prototypes 1-7. Prototype 7 is now owned and being refubished by Mitch Castro in West bygod Viriginia. Mitch is the moderator of the Tilters group on Yahoo,

I'm already very familiar with those two websites. But they do not provide anything that we can use, really. It's just a bunch of stuff about vehicles that people supposedly have made, or will make. But I don't see anything that we can use.

There is a guy in Australia that I've been watching for a couple years now, and he has an incredible tilting system available. You can read about it at the following website:

Here is one of his videos...

There are a few other videos where he shows-off the tilting mechanism a lot more.

What do you guys think of this?

EFFING AWESOME. I think a bit more tilt is desirable but dang that looks fun. Open air design and all. Would be a week or two away from an enclosed body if I got a hold of that thing.

Here are some notes about the above 3 videos...

* notes on the video clips..<o:p></o:p>
<o:p> </o:p>
[I]a] "slow speed" Clearly demonstrates the simple steer control of the vehicle... right down to stop, with seamless simple steer control throughout all vehicle speed variations during all manouvers.<o:p></o:p>
Included is a severe road camber change taken with little effect on the vehicle. Surprisingly, even though the vehicle is less than a meter wide it is less disturbed by bumps than a conventional car.<o:p></o:p>
<o:p> </o:p>
[I]b] " dirt" Shows the vehicle sliding on a fine gravel dirt surface. Although it might not be obvious, the vehicle negotiates the corners in an all wheel drift, which is tending to understeer. The vehicle has very unusual abilities to maintain a controlled balanced drift automatically with no attention from the driver [see Patent]. The driver simply observes the steered path and if the drift is too wide reduces speed, or varies his input on the control. I show a deliberately induced power oversteer which is corrected by opposite lock on the control [ in a conventional manner].... however notice that the driver input on the control is fundamentally connected to the tilt of the vehicle, and the steered front wheels are dynamically connected to the tilt. This explains the self regulating abilities of the vehicle system [ see my Patent for more details]<o:p></o:p>
<o:p> </o:p>
c] "medium speed" Shows corners taken at higher speeds. The steer of the vehicle is precise, and the feeling is very pleasing.... even if you don't drive" fast".... it feels good. Notice the dynamic stability " hands off " which demonstrates the fundamental inbuilt stability of the system. As speeds increase the vehicle [as it tilts] tends to load its outer wheel/s more than its inner one/s..... and the driver feels some lateral force on his body, which is a subliminal feedback method I employ in this vehicle because its a naturally expected component of simple steer style control. Notice how the driver tends to shift his upper body into the corner with the rotation of the control ? All this is due to the vehicle settings which provide the driver/ machine interface which appears to be so poorly understood by others in this field.<o:p></o:p>
<o:p> </o:p>
" and its all done mechanically and fail safe"<o:p></o:p>

Derwin, great videos! When you say he has this system "available," what does that mean exactly?

On that Mother Earth News page, in the Related Content down the left side, is an interesting article on:
Electric Car Conversion: The Amazing 75-MPG Hybrid Car (http://www.motherearthnews.com/Green-Transportation/1979-07-01/Electric-Car-Conversion.aspx)

(wish I still had my '69 Opel GT....)

I tried making one with 3 in back but could never keep center of gravity and have all the wheels on the ground at the same time. I tried a 2 wheel bolt on since the factory cost was too high, and I did not want to slice up the bike.

He calls it a FTC - Free To Castor tilting.

Here (http://www.youtube.com/watch?v=PhGMtoOKht0)is another vehicle using this principle - TBX3.

Me starts to like it :)

TiltingVehicles.net (http://www.tiltingvehicle.net) has many documents and descriptions of the principles. Any engineers able to find some weakness? It almost looks too simple :|

Philp James' patent (http://www.wipo.int/pctdb/en/fetch.jsp?LANG=ENG&DBSELECT=PCT&SERVER_TYPE=19-10&SORT=41258633-KEY&TYPE_FIELD=256&IDB=0&IDOC=26451&C=10&ELEMENT_SET=B&RESULT=1&TOTAL=1&START=1&DISP=25&FORM=SEP-0/HITNUM,B-ENG,DP,MC,AN,PA,ABSUM-ENG&SEARCH_IA=AU2005000110&QUERY=%28WO%2fWO2005%2f075278%29+) and disclosure (http://www.tiltingvehicle.net/NoticeToPatentExaminers.html).

Edit: Derwin, now I figured this is exact the same site you copied those quotes from. For some reason I just don't see your link ?:|

Yep. That is the website and the guy that I have been watching for a couple years now.

And, according to his site, he is offering the tilting system to those interested, but I don't know at what price.

Hey Derwin, there is something wrong with this thread. When I try to read past page 1, it gives me an error...
