A lubricating fluid feed in a transmission

摘要

A component, e.g. a clutch ring or hub 70 in a one-way clutch, surrounding an axis 23 is arranged to direct fluid along a flow path in a transmission for a motor vehicle. The clutch ring 70 includes a first wall 74 having an inner surface 76 facing the axis 23, a number of holes 80 spaced about the axis 23 each of which extends through the first wall 74 and a channel 82 formed in the first wall 74 each communicating with one of the holes 80. Channels 82 have a base 84 with a length that extends angularly about the axis 23 and a depth that decreases along the length as the distance from the hole 80 increases. The channels 82 are open to permit lubricating fluid flow into the channel 82 and channels 82 have a maximum depth at the holes 80.
