Hyundai/Kia's new Uni Wheel moves gear reduction and the CV joint into the hub
- londons_explore 3y agoHow do they seal it to stop mud getting in those gears? A huge rubber boot? Some kind of set of sliding metal plates? Seems hard to design something sufficiently robust to last the lifetime of the car while not letting I. A single drop of water or grain of sand (which would make quick work of destroying these gears)
- londons_explore 3y agoso in a typical EV, the torque travels through one gear to hit the wheels (there are other gears involved, for example in the diff, but no energy is lost to friction inthem on a straight road). The CV joint, while straight, has no friction either. In this design the torque travels through 4 gears. That has to cut efficiency rather substantially?
- MBCook 3y agoI think their theory is that that’s more than made up for by the lack of the traditional CV joint and its losses at different angles.
