Patent attributes
One or more techniques and/or systems are disclosed for a transmission variator. The variator receives input power from at least two power sources and provides variable speed output power paths for the transmission. A variator clutch assembly transfers input power to a variator shaft, which drives a planetary gear assembly, including a sun drive gear, planetary gears, and one or more ring gears. The ring gear(s) provide output power to a high output and low output gear assembly. A double reverse tapered spline between the sun drive gear and sun gear to provide forward thrust on the sun gear. A lubrication pin in the planetary gears can provide pressurized lubrication to the planetary gear assembly. A ring gear retention key can be disposed in a spur gear of the high output gear assembly, and ride in a groove in the underside of the ring gear to provide for alignment.
