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.
