I don't get what this does or what's the benefit. There's still a cv-joint there. Otherwise the wheels can't turn
It replaces the cv joint. Watch the video.
There's the CV-joint
The video shows how their gears go up down and side to side to perform the function of a cv joint. So whatever that cv looking thing is, it's not a cv joint.
If it was just a solid axle going from the motor to the uniwheel you couldn't steer the car. It doesn't allow for such movement.
Looks like it eliminates the engine-side cvd but not the wheel-side.
Can't really do that, u-joints and cv's work in pairs to balance the angular change
There is no angular change between the axle shaft and the engine.
The motor could turn with the wheel. You could have a wheel-motor without the excessive unsprung weight of the motor components.
It's a bit overcomplicated wheel reductor hub, used in some trucks and widespread in heavy equipement, but the input shaft can move a bit. And the artictle doesn't mention anything about oil in it or how it is sealed.
The motor could move with the wheel, but there goes that space they saved.
