A patent was issued on January 1, 2019 for VECTr - Variably Expanding Chain Transmission. VECTr is an expanding chain ring system which allows one to vary a bicycle's gears from 29 to 44 tooth equivalent settings. By using a lever shifter or an index shifter calibrated to VECTr's settings, one can change gears as quickly and as easily as on a derailleur system. Since the gears changes are not made while the chain is under load, nor between parallel chain rings (as on current derailleur systems) there is no chance of the chain slipping of falling off. A prototype is planned, but I am also seeking to license VECTr to a qualified manufacturer. For more information, visit vectr-gear.com.

Dammit, I literally drew this exact design up myself too thinking it would work! someone beat me too it.

@Bassotronics 2 года назад

Darnit. I was thinking about making something like this today and it’s already been done. Back to the drawing board for me.

I'm sorry your dream was thwarted. Usually people tell me it was already invented 100 years ago. This particular design was not, of course. You can have the consolation of being in good creative company. Great minds think alike, and all that. Thanks for your interest and comment.

man i was thinking about designing something like this for a few weeks, i thought about everything, a locking mechanism for the expanding teeth, a corresponding rear sprocket, the fact that they cant expand at the same time. welp someone made it

@benjaminmartinez8199 9 месяцев назад

Same thing lol 😂😂

@ohmdur9224 3 года назад

Iam an inventor and it appears, to generate sales, you need more spokes on the sprocket retainer with more area for teeth for smoother operation. Smaller 10 or more spoke retainer would make this happen.

@bobkeller8383 3 года назад

I like the concept. Looks a little clunky and very noisy. Get that sorted out and I think you'll have something

@endtimeslips4660 Год назад

good idea. but i think this will have vibration issue in high speed.

@Creeperboy099 4 года назад

I think that with these systems, it would be best if you had a chain tensioner that adjusts with the ratios

@vectr-variablyexpandingcha118 4 года назад

VECTr works with bikes with rear cassettes and tensioner/derailleur. You can see that in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-07FzZ3WcknU.html

The internet is incredible. While nagging over my nexus hub gearbox that doesn't coast realy well, I was thinking about how a CVT could be applied to a chain-driven system. And of course, some dude made it already. Great stuff! Any ideas on how to reduce the gaps/jumping chain?

@charlespalmer157 2 года назад

Any idea what overall efficiency might be? Many of the friction drive bicycle transmissions have low overall efficiency. A common planetary gear set can achieve up to 97% efficiency.

Not sure if it will work for MTB too much shaking and bumps

@vignan4553 5 лет назад

Can you explain me how the pulley's dia changed. Please.

@vectr-variablyexpandingcha118 5 лет назад

There is a locking mechanism on each gear segment which is released, and the segments are moved to new radial positions, by their contact with a controller while being moved by the cranks' rotation.

@vignan4553 5 лет назад

@@vectr-variablyexpandingcha118 can you please explain me what type of controller is used for shifting the radial positions along the constraints?

@vectr-variablyexpandingcha118 5 лет назад

@@vignan4553 The controller consists of two curved plates which are slid fore and aft by a cable attached to a friction shifter mounted on the handle bar. An electric actuator controlled by wired or wireless switch could also be used.

Looks like a very similar process to Veridrive from about 5 years earlier. Bit better video as a potato cam appears to have been used for the Veridrive ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-RQHvjktwc0k.html

@petersvancarek 3 года назад

not much different to this ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-yweIWBC9-OA.html and I saw something much, much older. None of these are used.

@vectr-variablyexpandingcha118 2 года назад

VECTr is not very similar at all. The chain-engaging gear segments on VECTr change radial position one at a time, not simultaneously as in the other device. There are very many other differences.
