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： 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.

摘要： A transmission having an electric motor/generator includes a transmission housing and a bearing support rigidly connected to the transmission housing and substantially enclosed by the transmission housing. A stator housing is substantially enclosed by the transmission housing, and is rigidly joined to the bearing support by a plurality of rivets, such that torque may be transferred between the stator housing and bearing support. The stator housing may be formed from a first material, and the bearing support may be formed from a second material, different from the first material. The stator housing and bearing support meet at an interface region, which may be characterized by an absence of a welded connection between the stator housing and the bearing support. The interface region may be characterized as a slip fit, such that the stator housing and bearing support are matable by hand.

摘要： A hybrid powertrain includes an engine driving an engine output member, such as a crankshaft. A damper is directly connected to the engine output member, and a transmission input shaft is directly connected to the damper, for common rotation therewith. A dry damper is configured to allow the hybrid powertrain to be characterized by a lack of either a flexplate or a flywheel. A method of manufacturing a hybrid powertrain is also provided, including assembling a fully-functional hybrid transmission at a first manufacturing facility and assembling a fully-functional engine by joining a dry damper to an engine at a second manufacturing facility different from the first. Each of the fully-functional engine and hybrid transmission may be tested separately from the other. The fully-functional engine and hybrid transmission may then be shipped to a common assembly facility, and dry-mated at the common assembly facility, forming an assembled hybrid powertrain.
