Having these gears in the hub instead of a motor would decrease unsprung weight.
Comment on Behold The Hyundai Uni Wheel. Transportation May Never Be The Same
ZMonster@lemmy.world 6 months agoI mean you’re not wrong, but without separating the single motor to one at each wheel, you’d still have to translate the power from one point to each wheel. The uni bearing doesn’t provide that benefit. Separate motors DOES. And tuned and articulating short shafts are a new thing. So even without this new bearing as long as you had separate motors for each wheel all you would have is a short CV shaft between the motor and the wheel. Hell why not save all of the space and just incorporate the motor into the hub??? Since BDC motors are more efficient when wider and smaller, it would be very easy to fit them within current day hubs.

I didn’t think about that. Thanks for pointing it out.

The gears are necessary to allow the wheel to move without having to move the input shaft.

It directly replaces the CV, so it’s the thing saving the space. Sure, if there was still only one motor, and a shaft connecting the two sides, less room would be available. But the space saving, and the reason why splitting the motor in two makes sense in the first place, is the uni wheel.

Ah, really good points. Thanks for the perspective. My expertise (if I may do generously call it that) ends at the manufacture and assembly processes. Thanks for the perspective.

Honestly, I get most of my knowledge from watching a bunch of youtube videos, so it’s not like you’re talking to an engineer or anything haha
But I do usually like to pick out the more technical videos, explaining the theory behind all this, so I guess I picked up on some things ^^
