It meant that you had something stable to pivot yourself from, and your brain/inner ear had a reference point when your cornering.

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.
@MetalMachineShop2 ай бұрын
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.

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 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!
@MetalMachineShop2 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. .

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.

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.

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.

How heavy is the trike? Can it also hold strong sprints to go faster?
@MetalMachineShop2 жыл бұрын
it’s over 20kg, there is quite a lot of spring in the front tilting arms already and it would be possible to add suspension to the rear as well by changing the design a bit,

What problem does the tilting solve?
@MetalMachineShop2 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.

Hi, the ground clearance is about 90mm (not enough). The top of the frame is about 600mm off the ground at the highest point.

@MetalMachineShop5 ай бұрын
The weight is about 25kg. Very heavy, but the frame could be made a lot lighter.

@@kusukacolaylowlee1611 Size of print and cost being the most obvious. Do you know anywhere that can do a 2.5mx400mm print at an affordable cost? Plywood is cheap, strong, easy to modify if he gets something wrong and has been used to great effect for hundreds of years and can be used with minimal and low cost hand tools.

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.
