Nice start - but for max compactness I think the front wheels need to fold back instead of forwards, removable seat and off set the rear wheel to get more fold with tire moving past the frame and you still got to figure out the hardest part - incorporating the chain system as to having no issues during the folding. Don't ask me how, I have no where the imagination you have. Keep up the good work. Cheers, Patrick
Thx for the vid. What actually controls the leaning action??? I mean is it controlled by the steering angle? And if so how it gets pushed back upright? Years ago I rode one with leaning action depending only on my arm force. Wasnt good, permanently uncontrolled and took a lot of power especially when starting to pedal. I would thank all of you for some input.thx.
Hey, trying to figure out what did you do with the steering. If im not wrong you are using a Dual Drag Link System, so how did manage to make the whole thing collapsible?
Hey, sorry everyone! I haven't looked at this video in years--it's on an old account. This design does not actually work. It's mostly just a fancy animation I made for school to showcase various joints in NX, the CAD software I used. (I was not marked on whether the design would actually function! haha) If the collapsing function was removed, however, it wouldn't take much to make functional. Collapsing the front wheels the way it's done here complicates everything enormously. For operation, I imagined it would function similar to a normal bicycle, i.e. rear wheel driven, would remain upright due to gyroscopic effect. (So what's even the point of having three wheels? Primarily aesthetic!) Springs can be added to the front control arms to remain upright under static loading but still allow for a limited amount of leaning. The linkage between the handles and steering needs tweaking, too, but the design pretty much comes straight from go-karts. Ultimately, there is no lack of resources for designing leaning trikes on RU-vid, and I encourage you to keep looking for designs that work. I hope this video has helped inspire some people!
Awesome! Collapsing feature can be useful for ultra-light models, to allow better portability with other means of transport (like taking it on a train with you for several hundred kilometers, and then use the Trike for local commuting). I would fit it with batteries e-motor (perhaps even hub motors) cover it with ultra-light transparent (at least in horizontal plane) cover to protect from rain and wind and it will be the ultimate city commuting vehicle with potential to go for not too long highway trips. Do you know a company producing similar trikes?
Good question even after 6 yrs +1 if pedals drive only one front wheel or only rear wheel, and front wheels are independent, then real leaning function can be achieved.
@@prakash525 I think @txusicB's question is "are the front wheels free to castor." Free-to-castor wheels are inherently self-correcting and follow the required path automatically to keep the vehicle in equilibrium. The ideal design is: Step 1: Counter Steer to induce leaning. Step 2: "Somehow" disconnect the steering and let your controls now make corrections to tilting while the "now un-steered wheels" are free to castor. Step 3: To lean out of the turn repeat steps 2 then 1 i.e. in the opposite sense. Step 4: patent your design and make $$$$$$$$$$$$. For ideas look on youtube for the user "Tilting Vehicle"
