Enlarge / This picture reveals the Uni Wheel idea in three completely different levels of articulation. (credit score: Hyundai)
We like bizarre new engineering concepts right here at Ars, and as we speak we have now a very fascinating one within the realm of electrical vehicles. It is referred to as the Uni Wheel, and it has been designed by Hyundai and Kia as a approach to revolutionize the format of an EV powertrain to extra effectively use house. The truth is, the automakers say it isn’t only for vehicles—the brand new drive system works with wheel sizes as small as 4 inches to as massive as 25 inches.
For EV lovers of a sure bent, there’s one thing slightly inefficient about the best way just about each EV powertrain is laid out.
Not the battery within the center, although—whereas it is cumbersome and raises the general top of EVs, it is sensible for weight distribution, though individuals engaged on structural carbon-fiber batteries have some completely different concepts about that. The issue is the EV drive unit, a cumbersome factor that incorporates the electrical motor, some gearing, and normally some energy electronics. These take up room between the axles and should be packaged round.
