It's still a fixed ratio though?

Oh I was looking at constant velocity transmissions. Similar concept to the uniwheel, as far as the gearing. As least, if I understand it correctly.

When transmissions are discussed, the acronym CV stands for continuously variable. (As opposed to a transmission with 3-5 discrete gear ratios.) But yes, some CVT designs do use planetary gears, especially for hybrid gas-electric models.

CVJ = constant velocity joint

CVT = continuously variable transmission
