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
Thank you for squaring me away, here.
