Newbie. So be gentle with me.



No, the ackerman is in the struts axle a lil’ and the angle of the strut in the wheel well, And there is big camber in velomobiel front wheels. The three point ackerman is how good your jig is and your measurements & welding. Simple easy to do front end alignments on velos if you spend the money and buy from velomobiel.nl. Come to your front door like my front door/paypal with cell phone call to theo.

The future, since l have molds for 2 kinds of velos (my velo and my velotilt) l will also build the carbon tub’s for trike people. Im 1/2 way good frame builder but toooooooo much time.

Carolina, I am just discovering this site. I live in Virginia and want to build an efficient velomobile as an electric car. I am intrigued by this 4 wheel design you have. Is there somewhere that describes how to build such a 4 wheel bike?

Thanks
Kurt

Mule was nice ride, pinion/quattrovelo rear. Frame was heavy. Learned alot from it. Guy in california wanted it worst than i did. Loaded it on freight truck other day. Want need another mule for r&d work.

The old mule went to the barn some months ago. I robbed all the hardware from it and installed in this new unibody i made and been riding it since july 1st or somewhere near. Next i will make a velomobiel with no front or rear cowlings (i like waw velomobiel) and no top. Low walls near your elbows. A nice unibody that you can install velomobiel hardware yourself.


Mule hardware in this 4 wheeler unibody i made nowdays: velomobiel.nl

Sure: velomobiles made by top 4 or 5 companies do not have much of a turning radious :)

A more accurate way of saying this would be "velos designed by Quest do not have great turning".

This is some nice work. Any idea what the turning radius is at this point?

Carolina, can you post a close-up of the front suspension, to use as inspiration?

With time allowed i will covert heavy steel frame to my sq. carbon tubes. Pulled the 2 part mold below from the six foot steel tubes.

Ive made a pile but need more for myself. Not on front burner, mule is a great shop tool as is and grocery getter.

1st sample made:

Keep looking, its way different than what ive ever seen. Stare! Zoom in!

Each airbag holds 58 lbs.. Sway bar, traction bar up under/hard to see, 2 lil black rear shocks, 2 air-bags is all free-floating. Just the 2 most forward bolts are mounted solid. You can see differential either/up under cassette.

THE SHOCKS,AIRBAGS, TIRES SUPPORT THE WHOLE FREE-FLOATING UNIT. KINDA FRAMELESS.

Allert is the owner of velomobiel.nl,, he designed this over couple years.

Thanks jjackstone, that is the idea. This is a way off with multiple projects first. Actually the velo mule rear is more like the GM coil spring rear end. The older four wheel drive trucks used Dana 60 solid axles with U-joints at each wheel.
jjackstone Posted - 10/16/2017 : 08:45:31
Grant, Maybe you're looking for something like this.

Would suggest taking this to a new thread though if you wish to continue discussing it so as not to hijack Carolina's thread.

There is a trike like that on youtube, front wheel drive.

Mostly to save weight. Playing with ideas for a pedal car when my wife retires and we live with the grandchildren in flat terrain. A differential would take the place of CV joints. Twisting V belts would be easier. Hilliard Co. locally could be a source.
Speedbiker Posted - 10/15/2017 : 14:29:54
And you'd make Rube Goldberg proud!
Tom Schneider Posted - 10/14/2017 : 23:52:37
You could try twisting chain front wheel drive. A cog on each front wheel with a chain going to an overhead axle with 2 freewheels. This is definitely a half baked idea that may be ugly!

Tom
Speedbiker Posted - 10/14/2017 : 22:43:23
Sure it could be, if you can design, model, and manufacture all the fwd steering components, tiny CV joints, new axles, and suspension(if wanted). I have the design, machining, and fabrication skills, but why do you want to know?
carolina Posted - 10/14/2017 : 20:45:35
I don’t really know answer. Grant

Grant-53 Posted - 10/14/2017 : 15:13:13
Ditto SB comments. Could the differential be adapted to a front wheel drive system?
