Comment on Behold The Hyundai Uni Wheel. Transportation May Never Be The Same
trash80@lemmy.dbzer0.com 6 months agoWhat for? The axis of the driveshaft would always be parallel to the axis of the wheel and perpendicular to the axis of the motor.
Look at this hand drill:
The hand crank is the electric motor. If you rotate the drill about the hand crank axis, you don’t change any angles between the drivetrain components and don’t need CV or universal joints
Now imagine there is a handle sticking out of the crankshaft that needs to rotate around the shaft with the hand crank as it gets turned. That is the motor.
The video never showed the motor moving along with wheels turning, only the up and down part. In fact, when they showed space savings they showed the motors as stationary with no clear way to turn.

What are you referring to as the crankshaft?

Suspension movement still requires flex in the shaft. There’s no way around it unless the engine moves with the suspension

Yes, there is.
Take a conventional front engine, rear wheel drive drivetrain. Rotate the drive train 90 degrees about the rear axle, as if the automobile has its nose in the air, with the driveshaft oriented vertically.
You can steer the vehicle by rotating the entire axle around the axis of the driveshaft, though it isn’t perfect or space efficient, it would require no universal or CV joints. It would behave sort of like a vehicle with an articulated frame.
The axle could be fixed vertically with uni wheels at the ends of the halfshafts allowing the wheels to travel vertically independent from the axle.
Do you understand so far?
