摘要： An assembly in a transmission of a motor vehicle for communicating lubrication oil to a bearing in a planetary gear set includes a planet carrier having a plate with an inner groove in communication with a slot of a bushing, a pinion hole, and a second passage that communicates between the inner groove and the pinion hole. The planet carrier further includes a pinion disposed within the pinion hole and a bearing disposed on the pinion for supporting a planetary gear. A groove is disposed in the pinion and is in communication with the second passage. A third passage extends from the groove into the pinion. A fourth passage extends from the third passage into the pinion along an axis of the pinion. A fifth passage extends from the fourth passage to the outer surface. Pressurized lubrication oil is communicated through the plate and pinion to the bearing.

摘要： A method and apparatus for efficiently cooling and lubricating rotating components in a hybrid transmission is provided. By efficiently managing cooling flow to and between the rotating elements, flow requirements and associated pumping requirements within the drive unit are minimized. In addition, by providing a method for placing the fluid directly on the required components, spin losses associated with component contact with stray oil are reduced. Combined, the reduction in pumping and spin losses create a more efficient drive unit and an overall more efficient hybrid drive system which directly leads to higher fuel economy.

摘要： An input shaft for a hybrid transmission includes a cylindrical hollow shaft portion having internal and external surfaces. The internal surface defines an internal cavity coaxial with the hollow shaft portion and has a splined portion configured to allow power to be transferred to the hollow shaft portion. The input shaft may further include a freeze plug press-fit in the internal cavity, configured to fluidly seal the inner cavity in embodiments with a cavity extending throughout the input shaft. The splined portion may be a broached spline. A method of manufacturing a hybrid powertrain includes forming a hollow transmission input shaft and press-fitting a plug into it, such that the shaft is internally fluid sealed. The shaft is mated to the transmission which may then be filled with fluid and tested for operability. The shaft may be dry-mated to an engine output member for common rotation therewith.

摘要： A transmission includes first and second clutch members rotatable about the same axis. An axial groove is formed in one of the members to distribute lubricating fluid to the other member. Preferably, clutch plates with radial grooves extend between the clutch members. Fluid flows from the axial groove through the radial groove and across faces of the clutch plates to separate the plates during disengagement in order to minimize spin losses.
