Cargo Trike with 3D printed double wishbone suspension - #1

[@MarkHopewell]

How stupid am I?! I thought about making a full size mock up of my design but never considered a much smaller model! Thank you for prompting me to consider something much smaller to test my design!

[@pedro-neves]

Thank you for the kind words;) And good luck with your build!

[@svelobikes9049]

Looks great! Thanks a lot, for the video, I like the design's elegance!

[@pedro-neves]

Thank you!

[@MrJdorrington]

Great project. Looking forward to seeing its progress.

[@Jorgeaguiardacosta]

Congrats from Brazil, please Pedro, turn on the subtitles, this projetct is amazing, and i will start to make one soon, but i will not make cargo, only a trike to transport me and my daughter with 11 years

[@pedro-neves]

Hello Jorge, indeed this video did not have subtitles. They are usually created automatically but for some reason, in this video, it didn't work. If you see my most recent build, it does have subtitles: kzbin.info/www/bejne/p6azd3l_lr5rbMUsi=pqZOUaSMyBJclad0. Good luck with the build for you and your daughter! Cheers!

👍💯% Красивая подвеска получилась.🤝🤝🤝

3D printing is a great way to test geometry, but unless you are printing ABS with CF at 100% infill, I don't think you are going to have sufficient structure, particularly with braking forces.

[@pedro-neves]

I agree fully! I'm printing with PLA at 20% infill to iterate to a geometry that I'm happy with. Also I'll try to optimize design for strength.

So Cool. (From Thailand)

[@AuroraCypher]

This is amazing, will you be sharing the 3D printed files of the double wishbone to modify please?

[@pedro-neves]

Thank you;) I will share the drawing files of everything. Next video that I'll release I'll share the drawings of the parts to make the wheels (and I'll explain why I'm making wheels). In the video after that I'll have an improved version of the suspension and share drawings. But these will be all metal parts. If you want actually the files of the 3D printed parts of the version 01, let me know and I'll make them available.

[@AuroraCypher]

@@pedro-neves My goodness youre amazing Pedro thanks so much, Ive been trying hard to make a trike, however I ran into problems with the wheels, fundings and logistic including wishbone. You actually help me out a lot. Please anything help at this point.

[@pedro-neves]

@@AuroraCypher , Hi there, I made the drawings in stl files available via my website: sites.google.com/view/pedro-neves/home/cargo-trike-v0 Let me know if you need the files in other format or any help. You're welcome to write to my email: [e-mail].

[@AuroraCypher]

@@pedro-neves Thank you Pedro much appreciated ! you are very kind and wonderful. I'll have a look at the files thanks again. When is the next video of your build available please the new metal parts looking good

Show parabéns 👏 pelo projeto muito bom mesmo um abraço 👏

Obrigado!! Abraço!

Obrigado e tudo de bom Alvaro!

Id like to see the results if this was nylon cf

[@pedro-neves]

Never printed with Nylon but I've been curious to try with the new filaments with carbon fiber!

[@donalexander1933]

@@pedro-neves nylon is tricky nylon cf not so much

[@donalexander1933]

Are these files available ?

[@pedro-neves]

@@donalexander1933 , I started sharing files more recently as the design matures. Please find them here: sites.google.com/view/pedro-neves/home/cargo-trike-v1 I'll share more as I release new versions. Thank you for being interested;)

Merci.

Merci a toi;)

[@stevenroelandt5747]

now that you have all the parts you can cast them in alu from cans

[@pedro-neves]

That would be cool;) Actually I'm pretty sure the final version will have also an aluminum frame.

[@murraymadness4674]

I think you have made it much too complicated for a bike, given most have no suspension..I am looking into this because a reverse trike doesn't work too well when the ground is not flat, one front wheel going into a hole tips the whole bike. But I think you can use a simple trailing arm setup to give vertical movement that is still along the outer edge and have the entire unit pivot like no=suspension tadpole trikes. Maybe use some torsion bars instead of springs. Simpler is better with bikes.

[@pedro-neves]

Thanks Murray. Actually, I'm also a fan of simple. Like da Vinci said "Simplicity is the ultimate sophistication";). And I will get there. Just need to iterate a little bit. And, the next version will have a tilting mechanism;) I think it will be pretty good in stability. In any case, I'll keep iterating until I get something that works very well.

[@themostoriganalthing]

Smashing that bearing into the hub with the hammer face and not even using a brass block or anything come on man you're better than that, also that printed material isn't going to stand up to repeated banging and the brake forces on the hub. I hope that's just a scale model prototype and not the finished article.

[@pedro-neves]

Absolutely. I definitely recommend against hammering bearings. Best would be to use a press or a vice. Thanks for the heads up! When making instructional videos, things should be done the proper way. Noted and will apply more in the future. The printed parts are prototypes. A way to develop geometry.

[@tomjakobsen8110]

Nice build and it even looks very beautiful... Which is important in my opinion! Personally i would enjoy to take it for a testride until it reveals all the weak spots (-; how much weight do you think it will carry in the long run? But... I would miss using my hips kzbin.info/www/bejne/raG4dZdsf6lsj7csi=wMuqfQTOhJIb-Ist

[@pedro-neves]

Hello, nice riding in Christiania, on that video;) This trike that I made broke out shortly after being made, but I kept improving the design and build. Checkout the latest if you're interested. I'm testing now with 40 kg cargo: kzbin.info/www/bejne/p6azd3l_lr5rbMUsi=CIws-02qEh6G3C3P. Cheers!

[@tomjakobsen8110]

Thanks for making me remember how much i love bikes! In times with environmental challenges... Just a great invention in general and your build looks awesome and fun to ride! And the fact that you made your own hubs is quite impressive and leaves me with huge respect! (-: I'm not a theoretical builder like you but I used to drive bikes for a living and I'm quite sure 40.kg should work fine! But... I kind a have a feeling that the point where the tube for the steering/handlebar is welded to the main/horizontal tube will be a weak spot if more weight is added.. If you put this beauty into production as a people carrier you could add a "minor" tube (convex or...) approximately 20-30.cm up on the vertical tube going forward on the main/horizontal tube... To release a bit of the pressure where it's currently welded together. But Hey... I'm just a farmers boy! Which country do you live in? I'm guessing you're dutch? And keep up the good work! Simple and efficient! It's on my wishlist I feel (-:

[@pedro-neves]

@@tomjakobsen8110 thank you so much for the kind words and the suggestions about the build. I actually learn a lot from comments;) I'm from Portugal but I live in The Netherlands. I always loved biked but here they are part of everyday life so makes me happy to ride my own build;)
