Mono Posted December 29, 2015 Share Posted December 29, 2015 Nice idea, though not likely to be overly useful. I doubt that close-to-optimal, or even acceptable, specifications for a rear wheel electric motor and the tire of a car can be similar to that of an EUC.

MetricUSA Posted December 29, 2015 Share Posted December 29, 2015 Yea the car Electric hubs tend to be high voltage three/four pole ac motors...not 60 volt dc Link to comment Share on other sites More sharing options...
Planetpapi Posted December 29, 2015 Share Posted December 29, 2015 Hey they copied my idea. Several months ago I imagined a James Bond movie chase scene with car tire becoming a EUC, after 007 crashes his own car etc etc, and posted on this forum. Now I see that Ford patents it. That make me a smart person ahead of Ford. Ha ha. Thanks for this forum! We should come up with more frequent ideas to beat Ninebot's update cycles.

dmethvin Posted December 29, 2015 Share Posted December 29, 2015 I think their design looks really awkward. What if you had a really small three-wheel electric car sort of like the Isetta but with a rear wheel that was an EUC? The front wheels could have motors as well but only the rear wheel would be detachable and there would be some sort of kickstand for the rear to hold it up when you detached the EUC. Getting the torque/speed ratios right would seem easier with this, you could have the EUC do the low speed stuff by pushing from the back but use differently designed motors at the front for higher speeds.

Kroy Posted December 30, 2015 Share Posted December 30, 2015 It's just this innit?! Someone has noticed the similarity between this wheel and a back wheel on a Ford Focus!http://inhabitat.com/the-ryno-electric-unicycle-is-a-one-wheeled-muscle-machine/ Link to comment Share on other sites More sharing options...
Cloud Posted December 30, 2015 Share Posted December 30, 2015 This is not gonna be useful. This wont work. You disabke your car , take time to assemble the wheel and then ride the wheel. Why not ride the car to the final destination? This will only be used if the car breaks and is stuck and you have other way but to ride something else.

I was wondering exactly about this situation. I believe that it would make the patent invalid if the idea had been already published. Link to comment Share on other sites More sharing options...

What if you had a really small three-wheel electric car sort of like the Isetta but with a rear wheel that was an EUC? The better design may be to have a naked EUC embedded into the whole wheel, kind of a souped up hub cap. Naked EUC won't have the casing when attached to the car's wheel. You just have to put the casing when needed, to make it look like a real EUC. Why bother with all this in the first place? Why can't we just keep our beloved EUC in the the truck all the time? KISS theory. Link to comment Share on other sites More sharing options...
Cloud Posted December 30, 2015 Share Posted December 30, 2015 Am i missing something? If fords wants to develop that concept to save space for a tire/ wheel, why not make your spare tire a unicycle which can double up as a spare tire if you puncture one of your tires? You could always keep the spare tire/unicycle separate, assemble it momentarily and use. And if you get a flat, then you jack up the car and use the unicycle wheel as your donut. What am i missing?

AFAICS it's not you missing something, but Ford. The major advantage of your idea is that a reserve wheel can be largely designed to be a good EUC, it just needs to do the basics as a car wheel. The main challenge I can see: you need to find a place where the wheel is easily accessible, preferably also with a fully packed trunk. Link to comment Share on other sites More sharing options...

Yes exactly, and you dont need to disable your car ( remove the wheel) to use the unicycle. The wheel would be kept where you would keep your spare tire. In cars like Honday odyssey, the spare is kept inside the car , at the back , under a panel on one of the sides, it is very accessible. Ford focus has access from inside also but its under the trunk floor so if you have too much stuff in the trunk youd have to get it out. But not everyone necessarily has a ful packed trunk.as long as there is reasonable access. ideally though, every item should have its intended use. I wouldnt even combine the two at all...

EUC Extreme Posted January 1, 2016 Share Posted January 1, 2016 I think that the car tire weighs so much that due to Gyroscopic because it is impossible to drive. Link to comment Share on other sites More sharing options...

It seems though that the Ryno with a pretty big tire (as shown above) works fine. Link to comment Share on other sites More sharing options...
EUC Extreme Posted January 1, 2016 Share Posted January 1, 2016 But it is a custom-built ultra-light. It works. Car tire is very heavy. I have a 18 inch EUC rubber in addition to the pins. Already it increases the weight of so much that, the hard drive becomes challenging due to Gyroscopic. It is difficult to reverse. Car tire press many times, so it is impossible to drive the same way as EUC. Link to comment Share on other sites More sharing options...

And where did you find the specifications? (I always find it very difficult to get information on tire specifications and in particular on weight). And what's the weight of a car tire in comparison?

EUC Extreme Posted January 2, 2016 Share Posted January 2, 2016 Suppose for example that Rhyno use motorcycle tires. Which is also heavy. But it is many times lighter than any other car tire. Anyone who has hand-raised them to know that the weight difference is really big. From experience, I know that, a few hundred grams of EUC in the ring a lot of effect on driving. It may not be at a speed of 15kmh. But if you drive faster, the effect is enormous. For this reason, I would never want that ring EUC would be a bigger 18 inches. If not, then the rubber and the engine is very light. No matter whether a car tire 5 kilograms heavier, or 1 kilogram. In any case, it's too heavy. I know, because I now have too heavy rubber I Gotway because it has pins. It is a 40kmh speed really hard to control. Link to comment Share on other sites More sharing options...

Car tires weight apparently around 10kg,^1 the dry weight of the Rhyno is 73kg and it "is outfitted with a full-size motorcycle tire", which looks like a back tire (which I would believe is heavier than a front tire and nothing is said about "custom-built ultra-light").^2 22 hours ago, vee73 said: Anyone who has hand-raised them to know that the weight difference is really big.

I totally agree that it is desirable to have the least possible weight to accelerate and spinning. I don't see however why added weight to the tire, if balanced, is prohibitive to control an EUC, unless operated at the limit of motor output power. Added weight means that the power limit is at lower speeds though. ^1 Google ^2 http://rynomotors.com/meet-the-ryno/specs/ Link to comment Share on other sites More sharing options...
