Abstract
According to one or more embodiments, a clutch pack includes a first set of clutch plates arranged in an alternating configuration with a second set of clutch plates. The first set of clutch plates has a plurality of friction pads made of friction material and defining channels in the friction material. The channels are configured to allow lubricant to flow between the friction pads. Each of the friction pads defines a groove in the friction pad. The groove is disconnected from the channels. The groove thereby creates a flow induced high pressure region forcing the first set of clutch plates to a center between the second set of clutch plates.
