3-mode front wheel drive and rear wheel drive continuously variable planetary transmission

A front wheel drive or rear wheel drive continuously variable transmission has an input shaft, an output shaft, a continuously variable tilting ball planetary variator, a complex planetary arrangement having first, second, third, and fourth rotating elements, and a plurality of torque transmitting devices. The complex planetary arrangement has a simple single pinion gearset and a compound double pinion gearset, having fixedly connected planetary carriers and fixedly connected ring gears, creating a joint planetary gear carrier and joint ring gear. The outer planetary gears engage the ring gear which drives the output shaft. Selective torque transmitting devices include clutches and braking clutches. Alternative variations of the continuously variable transmission configurations utilize two simple planetary gearset assemblies instead of a complex planetary arrangement with and without variations of torque transmitting device configurations. 种前轮驱动或后轮驱动无级变速器，具有：输入轴；输出轴；连续可变倾斜球行星变速机构；复杂行星布置，其具有第旋转元件、第二旋转元件、第三旋转元件
