A 2nd steering arm will get rid of the constant left right wobble in the steering. Instead of push or pull, it will become: push+pull, which results in less/ no wobble. I had the same problem. The second steering arm was the solution.

Thank you very much for the suggestion to improve! I agree with the push-pull situation. I've been looking forward to upgrade to cable steering which would be pull-pull as well. Let me know what you think.

How would it work if you just use a bike chain instead of rods? Might be more susceptible to road bumps.. My other thought would be, if the rods were bent at each end, so that the bulk of rod length was under frame, it would be out of the way.. If you use the bent rods, you could make channels on the frame for them to slide in, so they wont wobble.. Also, I was wondering if this type of tilt steering could be adapted to make a self balancing system.. Using some kind of inverse feedback of the centrifugal force of the turn... I am thinking that people in a car going around a turn are pushed in their seats to the outside of the curve. If the bike seat has the same force, then linking the seat's left/right shift action to the tilt of the wheels, could possibly make auto correcting self balance system..

This trike looks great! Awesome work there good sir, very well done! :D A leaning trike with suspension is no easy feat to pull off, quite impressive! The idea of a second steering arm suggested previously is a solid solution, but it doesnt have to be a "chunky" piece like a mirror of your current singlesided version. It would suffice with a bowden cable, like a bike brake cable and tube. The goal is to tension the system in both directions, eliminating any slop/give in the steering mechanism, and you only need a small force to accomplish this. You can easily fabricate some wireclamps and tube end sockets with a drill and a hacksaw.

Same as I said to Phil Vandelay: I hope you'll always succeed professionally. People like you should always be hired in whatever they want in this area of expertise. It's hard to do all you do, but also document it and make a decent video out of it. That front component is a masterpiece. As someone said before, it might be copied by cargo bike builders. I just hope they reach out to you to be part of the development process. Cargo bikes are the future and hopefully, they'll replace cars and vans for most use-cases in urban areas. On the other hand, I'd love to see how you install the cargo bay and carry stuff around. I'm not sure if the last big hole you made for the steering is going to compromise the structure once you carry heavy loads and hit a pothole. Take my point with a pinch of salt because I studied industrial engineering but haven't performed as such for a long time haha.

getting this done with gasless mig welding is an achievement. however some of the beads are really on the edge of safety, outside of experimenting. you might not see it that way yet, but with a bottle of argon you could save an incredible amount of time grinding and brushing off the flux that hides defects. my own welding experiments have run on one B50 bottle since the covid shutdown. i'm going to have it refilled at the end of this summer. it was short of 500 bucks for the bottle purchase and the first fill. also gas welding means you can tig and mig, and both do less sparks than gasless. i'm already checking the next video 🙂

Plenty of caster is always desirable, as it makes for self-centering steering, and easy no-hands riding. Most people don't understand why it's really hard to ride no-hands on a downhill mountain bike: the angle of the forks is a lot steeper, so there is much less caster effect. In cars it means you simply let go of the wheel and the car straightens up automatically.

In the 1990's I was in an electric car racing club in HS. For my senior project I designed a trike with active camber front steering. It had a disc that the steering mounted to, as well as the upper control arms. The control arms would move in proportion to the amount of steering input. At the time we raced fairly large karts with 2 lead acid car batteries for power. With 20" bicycle wheels we had to slow down severely in the tight corners given our moving mass. If we went too fast, we would taco the rims. By this point in my high school career, I was a fairly disengaged loner who would rather be at home playing Half Life. I was given the opportunity to build my design, but at that time I was intimidated by metal fabrication, and very self conscious about my welding skills (even though I became a professional metal fabricator later in life). So I never built it. Teacher aide even tried to flunk me on my senior year for not taking the initiative, but I didn't care. I was over it. I had already competed in an international engineering competition a few years prior, so I just wasn't interested for whatever reason. I personally think it was just being a loner in a very cliquey small town school. I didn't feel like I belonged there.

To make your own hubs, mill 4 high corners with a round boss with a through hole in them as part of the first operation. Then clamp a piece of aluminum on the table and mill it into a nest with 4 threaded holes and mating round pockets. (threadmilled). Do not move or upset the nest and lightly bolt the parts to it one at a time and finish them. This will hold position during the flip. It is even possible to 3d print the nest and cut the dadum to get the precision you need as long as you take light cuts on the hubs. I print the threads right in the parts.

Congratulations on your workmanship, You are very dedicated. While I do experiment on the same lines, I must say that I never reach the same level of workmanship as putting ball bearings in the wish bones. Well done, and wish you all the best. There is a lot of variables operating at the same time, but I pay a lot of attention to the relation between the contact point of the wheel on the ground and the projection of the steering angle on the ground. This relation can come up with self cantering, instability , and hard steering and oscillations. The narrowness of that trike needs weight to be shifted around corners as otherwise the Centrifugal force will take over . At my old age I lile it to be a little wider so that the whole lot is stable when stationary and at slow speed which is all I can achieve, Congratulations once again. What you are preparing for at 6:10 is called " Rose-welding".

Also, I've been learning a lot from comments such as yours about the geometry of vehicles so, thank you very much as well for the teachings! Regarding the width of the vehicle, this is very much on purpose because I want it to go, as much as possible, through narrow spaces. The tilting mechanism allows for a compensation of the centrifugal force and makes it feel more like a bike, which I like.

Thank you! Indeed some of the components are 3D printed (most jigs) just because it's so easy and cheap to print a guide. If plastic is not suitable, sometimes I make jigs from wood. Besides the jigs, I made a machine for notching the tubes. I think this machines is pretty cool because it's a very accurate notcher and general grinder with many function. I will actually make a video about this machine. I estimate I'll release it in 1.5 months from now. Hope you watch it and enjoy it;)

just an observation - because of how you did caster, adjusting it also introduces pro dive into the geometry. it will feel soft and encourage more front weight transfer, and could make the bike feel even more twitchy esp. at faster speeds.

@@pedro-neves you can move the caster adjustment in the hubs if you want to separate the dive adjustment and caster. you may not feel the pro-dive right now since it's relatively light but it will progressively be evident as you load it with cargo. you can also check out suspension systems of RC race cars - the physics and engineering in those are the same :)

Pedro, you have done a super job on this design and I am amazed that you managed that with the limited equipment and work area that have. One suggestion, you could secure the outer race of the bearings in those tubes quite simply putting 3 or 4 light punch marks on the outer side of the tube in which the bearings fit then as you press in the bearings these pinch will solidly grip and retain the outer race, also I noticed when you the shafts thru the inner race the appeared to be a slide fit ,not good you do not want the shafts to rotate on the inner race which would happen if dirt and grit get in the ball race this will quickly cause the shaft to wear very quickly. However if you use shielded bearings( no dirt) and determine the position of the shafts within the bearings first then put three light punch marks at equal distance around the dia. this will make the shaft a good press fit in that inner race and prevent loose shaft rotation in the bearing. I look forward to the next video ,I hope to start on some framework for rev. trike in the new year I am 75 and need to do this soon or I will run out of time. GOOD LUCK.

I'm sorry fella, but punch marks, really? It's clear to me that Pedro's most excellent workmanship and punch marks either on the I.D.of the control arm tubes or on the O.D. of the shafts to close a loose fit don't go together. All that's needed for a job well done is a few drops of loctite brand stud and bearing mount and a squirt of accelerator and you'll have a fit that won't slip without having to punish the parts! An additional benefit of the compound used with sealed bearings will be in keeping any and all water out from between the bearings. ( I really don't like parts I've crafted to fall victim to festering rust and corrosion!) Cheers from ElMonte CA USA BP!

congratulations for your nice design! I have been building a few tilting designs and so far nothing is "quite right". You should consider using some kind of load on your test mules. In my experience steering geometry on any cargo bike is heavily affected by front axle loading. While it is important for the bike to ride kind of allright without loads, on any longjohn type design steering is always very compromised until you load something. Have fun tinkering!

Hello, thank you for that! I did consider the Ackerman geometry. You can see in minute 46:03 on a tight turn that the inside wheel turns more than the outside wheel. The reason why it seems like I doesn't have Ackerman is because the steering connection is straight. But, it is a few centimeters inside of the center of the turn radius off the wheel.

all these angles are subject to regular upkeep on a car, and i wonder whether that is because of things bending, or bolts coming loose. munro calls bolts threaded un-fasteners. i think that's quite clever. once you have a good setup, i think it might be preferable to have them fixed in place, even if that means they are no longer adjustable. unless thoroughly rusted together, all those bolts there could lead to considerable headache i think

That's a good point - why does a car steering become misaligned? I would definitely prefer to not have to regulate things from time to time. But, in this project, the regulation also has the purpose of finding the best geometry. I'm doing many tests now with different geometries and will share a video about that. Once I have the bets geometries, I will build the trike with less adjustable parts. Cheers!
