Abstract: A guide pin assembly for a CVT variator includes a retainer and a guide pin coupled to the retainer. The retainer provides at least three functions for the guide pin: pilot, orientation and retention. The guide pin provides lateral and axial constraints to a chain guide through which a chain extends.

Abstract: A multi-mode continuously variable transmission (CVT) for a motor vehicle includes a transmission input member, a transmission output member, a planetary gear set, a forward clutch, a brake, and a continuously variable unit having a first pulley, a second pulley, and an endless member wrapped around the first pulley and the second pulley. A first transfer gear set is connected to the transmission output member. A second transfer gear set is connected to the transmission output member. A dual clutch assembly is provided having a first clutch and a second clutch, wherein the first clutch selectively connects the second pulley to the first transfer gear set and the second clutch selectively connects the second pulley to the second transfer gear set. The dual clutch assembly provides two modes or ranges of continuously variable speed ratios between the transmission input member and the transmission output member.

Abstract: A planetary transmission includes a plurality of planetary gearsets. The planetary gearsets have a lubrication system comprised of pinion pins secured in side plates and central passages located within the pinion pins. The central passages or cavities have radially outwardly disposed fluid passages, which supply fluid lubrication to support bearings for the pinion pins of the respective planetary gearsets. Lubrication fluid is communicated into the cavities when thrust loads are imposed on the planetary gearsets and the thrust bearings disposed between adjacent planetary gearsets reduces the flow area for the lubrication fluid.
