Gyroscopic precession on an EUC

[@Dogo.R]

I wonder how much this effects the wheel when it has inertia going forwards. I assume the speed of the wheel spin increases this effect. But if that was happening their would be more inertia to resist this turning. I wonder the degree to which it actually turns like this when moving at speed. Could cause wobbles if it turns meaningfully.

The effect does increase with speed, in this example the max free spin speed of the V11 is 78km/h. But it requires the tire to be tilted fast. Much faster than riders generally turn at those speeds. So I don’t think the effect affects real riding situations at all. Camber effect on the other hand, it is the reason for the wheel to stay upright at speed (people call it “the gyro effect”), enables turning on a dime, and I believe it to be the main function that causes wobbles to wobble.

@@mrelwood_EUC Wikipedia'ing camber effect doesnt seem to result in anything that seems applicable. Is there another name of the thing youre talking about? I'd like to research it.

[@mrelwood_EUC]

@@Dogo.R Hmm. That’s how we refer it to at the forum (or cone effect), but I don’t know if it has a more proper name. This explains the phenomena: www.playfulengineers.com/rolling-cone/

@@mrelwood_EUC Wow ok this is the sort of thing Ive spent many hours thinking about.

My v10 does not sound like that at all Edit: btw is this possible to fix an overheating euc charger, or do i buy a not faulty one? Mine gets pretty hot, it is around 80 celcius while charing and charges very slowly at high temperatures

[@mrelwood_EUC]

If course it sounds different, it's a different wheel. The old base level chargers do get hot, but if you actually measured 80·C, there could be something wrong. I would first measure the output voltage of the charger. If it's not 84-84.2V, then definitely but a new one.
