Abstract
The present invention provides a friction plate with features to provide additional cooling for use within a wet clutch system. The friction plate has a core plate with a friction facing layer affixed to each face of the core plate. The first friction facing layer has a plurality of radially oriented lubrication grooves formed by a plurality of friction pads having porosity. Additionally, the second friction facing layer has a plurality of friction pads formed by radially oriented lubrication grooves whose centerline is coincident with the radial centerline of the friction pads of the first friction facing layer. Each of the lubrication grooves has at least one hole provided therein to introduce fluid to effect cooling of the friction pad opposite the groove. Additionally, the present invention provides a method of enhancing the performance of a wet clutch system.
