Bicycle suspension mono fork
An assembly with sub-assemblies. Includes everything as on images. Included a complete assembly file of improved DNM DV-22 150mm shock absorber, a complete 18" front wheel with a disc Disc brake rotor from Indrek Narusk (thanks!) and all the details. If someone would care to make a nice rendering or animation, that would be great :)
I'm not sure how much of the functionality is kept in the STEP file.
It was primarily designed as a front suspension fork for a lowrider recumbent bike, but it can also be used with a small folding bicycle or a delta configuration trike. The fork is used on Steintrikes "Speedster FS" bike. A photo of the actual bike is also included.

Nice. The suspension actually never gets that much compression, but still a nice animated gif ;)

Great animation SIlvio!!

Thank you friends. Robert! I took the suspension to extremes to highlight the movements. =)

It's Ok, I just made a note ;)

OK Robert I really enjoyed your drawing. This all parameters. I improved my knowledge by studying its construction. \ o / I wanted to ask a question. The brake system is in place? I think the record should be higher? Or the "pinch" should come down? In my animation it is moved down. Have you noticed? I do not understand Nesher sorry, I am Brazilian and my English is GOOGLE.HEHEHE

I was hoping for a comment by now :(
5 months agoNow, I like that front wheel assembly. That would be a nice Nose Wheel assembly on my T-Bird I Tri-Gear Ultralight Airplane, only with a small big fat wheel! :)

5 months agoHave you tried to put electric engine to any of your trike design? I'm sure it would be interesting to merge your concept with the electric bike motors (Thunderstorm for instance on batteries - I'm sure it would have rather interesting range)
4 months agoThere are several E-engines available, all built into the rear drive wheel, BionX and Crystalite, for example. There are some videos on YouTube showing it. :)
4 months agoI would REALLY love to try to drive it :) :)
4 months agoSoon I will upload a model (for presentation, not manufacturing) so you'll be able to download it and ride it a bit around your PC or build one in real life ;)
4 months agoThanks for the detailed SW assembly! I am looking to learn some more advanced construction and surfacing and this model will be very helpful to me (been studying the caliper).
4 months agoThanks :)
4 months agoWell, I could bother with that, but I'm too busy working on new stuff. This is just an example how some things can be improved without high-tech, just a properly implemented idea :)
4 months agoDid this ever go further than a model? I'm just curious if there was ever any anti-dive built in to the concept. Neat idea though.
3 months agoAaron, the third image shows the fork on the bike. Steintrikes Speedster (google it)
3 months agoNeat-O-Matic Robert! Did you design that? Are you familiar with the old BMW motorcycles, which used "Leading-Link" front suspension? Kind of similar in concept, but the fork was swept back, and the the swingarm stuck forward from it. The shock/spring went straight up, between the swingarm and the aft-bend in the fork. When you hit the brakes, the front end actually rises up slightly; a different sort of feel...
3 months agoThat's super-cool.
3 months ago@Mark, this method is more like the front suspension used on Piaggio Vespa... The mother of all scooter bikes :)
