Is looking really good. You must be pleased! I made a trike years ago with a handlebar like yours but it was linked to the front cross members and stayed level when you tilted. It meant that you had something stable to pivot yourself from, and your brain/inner ear had a reference point when your cornering.

What a great job on the trike and the videos. You could be an engineering professor. (Perhaps you are in your other life.) I learned a lot as I consider building a tilting tadpole cargo trike with tandem for me and my disabled daughter. You will fly by us encased in carbon fiber if all goes to plan. Be British now ... stay calm and engineer on. You have a nice community of weird HPV people forming around you. I look forward to your solution of the twitchy steering problem.

Thanks! I think the solution to twitchy steering is a higher overall centre of gravity. I have a second version on the drawing board which addresses this. I’m also thinking more along the lines of a partial fabric covering rather than full carbon fibre. This would in theory reduce drag and also give rain protection. Good luck with your project, hope it goes well.

Both return to center force and damping for leaning should help with balance, but little force likely be not noticeable, and large force will force you to lean more, and there is a limit. A combination of leaning AND tiltlock is very cool in theory (massive cornering potentil), but needs mastering in practioe.

Outstanding, going from design toprototype build. I can totally see this all carbon fibre with a polycarbonate shell or something similar. Have you thought about making the chain come straight down from the chainring onto a drive shaft that runs underneath then up to another chain, it could be an advantage regarding chain stretch or other issues especially reducing clothing snagging in it or getting oil on clothes.
@MetalMachineShop
@MetalMachineShop 4 ай бұрын
I have got a Mk II version on the drawing board. It will be carbon fibre or steel/al tubing next time around. The long chain is not ideal but a shaft would require a bevel gear at each end which would reduce efficiency and add complexity. I was thinking of having the hub gear central mounted with separate chains going to it from the pedals and from it to the wheel.

I really enjoyed watching your series Andy. Your initial CAD analysis of the Ackerman steering was incredibly insightful. Would linking the seat upright angle in relation to the body to the tilt angle solve the twitchiness? It would definitely add to the complexity. The pivot point would probably need to be about 250 mm up from seat so your shoulders could lean in as your seat swings out on a turn. The downside would be the rider's lean would be additive to the trikes lean - to get it to lean 30º, the rider would need to lean 60º in relation to the ground... The more I look into this, the more the complexity can spiral out of control. When I first came across Kazebikes's design, I thought it was a bit odd. But now the simplicity and stability appeal to me. In the end, rollover stability and maintaining balance at stop are crucial for an enclosed bike. So despite the challenges, a tilting tadpole trike is probably the best answer for that application. Thanks!
@MetalMachineShop
@MetalMachineShop 2 жыл бұрын
Dave, I guess anything can be achieved at the cost of complexity, leading to cost and weight. My design aim for this project was to make it as simple as possible. I think a slightly higher centre of gravity would help with the twitchiness. I did see a design where the handlebars were fixed to the tilting arms, allowing the angle of tilt to be controlled by rider input to the bars. At extreme angles this does, however, put the bars at an odd angle to the rider. My thinking is that if a normal bike can balance without all this stuff, then so should a trike is designed right. Sorry for the late reply to your comment.

An interesting idea that I've had, and turns out was already tried out, it a trike with air shocks connected with an air channel. This way you get both highly tuneable tilt damping, tilt lock by means of blocking air channel (solenoid?) and it would still work like suspencion when you hit a speedpump, unlike your system...

At 4:18 the steering angle of the two front wheels seem to be wrong as they are not turning the curve using the same centre of the curve I tend to conclude that the three wheels are not turning to the left using the same centre of the curve. passing through the real wheel axis. I do not think this is an optical illusion as I see it. The inner wheel turn more than the outer wheel, which does not seem to be the case here. Perhaps I am wrong but I have checked other turns to the right and the left with different curves. .

I might try getting hold of a cheap motorcycle steering damper from ebay and see if it makes a difference. The tilting and steering is a little twitchy. A higher centre of gravity would also help I think - plus give a bit more much-needed ground clearance. I am in the process of bodging a tilt lock as I think the main point of a trike is not to have to put your feet down when stopping. it will also be essential when manoeuvring around bollards or through very tight gaps.

It would be physically possible to arrange a shaft drive, but it would need to be made of parts that are not standard bike parts, so would be expensive. It would also need a bevel gear at each end, which is less efficient than a chain drive. The frame could be designed to partially enclose the chain, helping to keep the chain clean.

@MetalMachineShop
@MetalMachineShop Жыл бұрын
Sorry for not replying sooner. The tilting has tow benefits in terms of ride quality - first, it's just more comfortable leaning in than getting thrown to the outside by centrifugal force and, second, if either front wheel hits a bump, the frame is only raised up by half the amount. The tilting arms are also quite springy, so there is some suspension as a result.

The steering looks a little twitchy, is that something you’ll be able to get used to or can you adjust by adjusting the geometry slightly? How far will it tilt?

Well, the project has been on hold for a bit due to other priorities, however, what it really needs is a working tilt lock and tilt damper. Without a tilt lock it’s very impractical as it’s impossible to navigate in confined areas without dismounting. The low centre of gravity also makes it very twitchy on the roll axis, so not very relaxing to ride. Ground clearance is also too small. All this means I have drafted a design for a (hopefully) improved version, slightly higher, shorter and narrower. I haven’t decided whether to make it yet!

It looks like the Ackerman steering geometry may not be correct. I can’t make out the steering bell crank details from the photos so it could be that and/or the steering arms should be pointing towards the centre of the rear wheel/axle more. In any case, it seems like the inner wheel should be turning through a greater angle when steering, maybe? Looks cool, by the way.

The steering and tilt mech are not interlinked. It balances in the same way as a bike, but you can't shift your body weight so much.

@MetalMachineShop
@MetalMachineShop Жыл бұрын
Well it’s sort of on hold; the prototype proved the principle but is not really a practical machine in any sense. I’m working on a Mk II design, which will be slightly shorter, higher and probably made of steel or composite. The other key addition will be a tilt lock, which I would consider to be essential for negotiating confined spaces.

I would think your tilting design could improve the stability of a velomobile (trike) when cornering at high speed for the same track width. Is this already something you can confirm based on your prototype?
@Balorng
@Balorng 2 жыл бұрын
That's a given, but your velo will no longer be a velo, but a singletrack streamliner with everything that entails (succeptability to side winds). But adding tilts lock/damping will likely make it "best of both worlds".
@MetalMachineShop
@MetalMachineShop 2 жыл бұрын
yes it would, but it’s very challenging to design a velomobile with tilting wheels contained within the streamlined body. Wheels could be outside the body, but you are going to compromise on aerodynamics slightly.

@@MetalMachineShop make that "greatly less aero" due to massive interference drag (unless you shape the wheel spats to flow field, they should look like commas). however, have you read Craig Cornerius (lefthandedcyclist) blog? Even a very limited tilting can go a very long way, provided you can "lock" the tilting and prevent "tipover" to the other side, or somehow uncouple leaning from steering.

@@MetalMachineShop so long as you are willing to go e-assisted, among my ideas as torque-vectoring tilting arrangement, where tilting as accomplisted by reactive moment acting on trailing swingarms (not perpendicular like on, say, latest tilter by Arcimoto), and this also doubles as front steering without actually steering. To drastically increase "torque/power density" of such a setup you can use combination of regen braking AND torque vectoring, with *rear* steering for slow-speed manuevering (so you get all wheel steer, essentially) and series hybrid human driverain. I wanted to test this, but I have more pressing problems problems now, unfortunately. What I like about this concept is that it relatively simple mechanically and electrically/electronically and can allow for a highly streamlined vehicle that "may" actually outperform a more conventional one even in "net zero battery drain" /pure human power mode at high speed, with benefit of assisted climbing AND recuperative braking.

@MetalMachineShop
@MetalMachineShop 2 жыл бұрын
Good question! More comfortable leaning in than it would be on a fixed trike. Key benefit I think is that tadpole trikes can be very unstable at speed with a tendency to spin about their vertical axis (see horror video on KZbin); a tilting design should avoid this.

Plywood is used for convenience for the prototype. I think it’s perfectly adequate this purpose, but maybe not as a permanent solution. Many WWII fighters were made of wood, so it’s a reasonable option.
