ABSTRACT:
An overrunning clutch used between the clutch plate pack and central shaft of an input clutch unit of a vehicle automatic transmission includes a lubricant collecting and distributing unit that acts in cooperation with the outer race of the overrunning clutch to eliminate the need for drilling lubricant supply holes through the outer race. The unit is fitted to the outer race so as to form a subassembly therewith, and an end plate of the unit is spaced from an end face of the outer race to form a lubricant collecting chamber. Feed channels formed with the unit extend axially along the outside of the outer race, opening into the chamber, and are sized so as to fit within the space occupied by an equal number of axial splines, which are left off of the outer race. Then, the subassembly may be easily installed by simultaneously fitting the splines on the outer race and the feed channels between the teeth of the clutch pack. The feed channels take lubricant from the chamber and distribute it between the interleaved clutch plates.
