ABSTRACT:
A multiple disk clutch used in an automatic transmission of an automobile or the like has a plurality of input friction plates and a plurality of output friction plates. These input and output friction plates are typically supplied with a lubricating oil to prevent overheating and abnormal abrasion. In the preferred embodiment, the transmission employs a pair of multiple disk clutches in which selected parts of multiple disk clutches are modified to direct oil radially outwardly via centrifugal force to lubricate the input and output friction plates. More specifically, the lubricating oil flows through ports which engage parts with guide portions for directing the oil through apertures located in a cylindrical member adjacent the input and output friction plates. In one embodiment, a spring retaining member is provided with a plurality of guide portions for guiding and directing the lubricating oil to the friction plates. In another embodiment, a thrust washer is utilized for directing the lubricating oil to the friction plates.
