Abstract:
1. A friction plate for a wet clutch system comprising: a rigid core plate; a first friction facing layer having a plurality of substantially radially oriented lubrication grooves formed by a plurality of friction pads having porosity, said first friction facing layer being mounted with respect to one face of said rigid core plate; a second friction facing layer having a plurality of substantially radially oriented lubrication grooves formed by a plurality of friction pads having porosity, said second friction facing layer being mounted with respect to another face of said rigid core plate and oriented such that each of said radially oriented lubrication grooves of said second friction facing layer is substantially aligned with each of said plurality of friction pads formed on said first friction facing layer; and at least one hole defined by said rigid core plate and in fluid communication with each of said plurality of radially oriented lubrication grooves, said at least one hole operable to allow sufficient fluid to pass from the lubrication groove from one face of said core plate through said porosity of said friction pad on the opposite face of said core plate to effect heat dissipation.
