  • Segmented friction material for clutches
    Patent number: 8939269
    Abstract: A friction plate for a clutch assembly includes a core plate and a plurality of friction segments made of a friction material. A plurality of grooves are disposed between said plurality of friction segments. Each segment has tapered sides so that the grooves have a first width adjacent the outer diameter of the core plate and a smaller second width smaller adjacent the inner diameter of the core plate. This tapered groove structure directs oil from the outside the clutch assembly to the inside to improve cooling efficiency.
    Type: Grant
