A friction disk assembly comprises an annular structural carrier including a plurality of recessed regions and torque drive notches spaced around its circumferential direction, and a friction lining mounted on the carrier, the friction lining having a flat wear (rubbing) face and an obverse face including raised areas corresponding to and matingly engaging the recessed regions of the carrier to prevent rotation of the lining relative to the carrier. The carrier may be formed of steel or other suitable structural material. The lining may be formed of virgin or recycled carbon, ceramic or other suitable friction material. The lining may be retained to the carrier by rivets. The lining may be provided with a structural casing configured to engage the recessed regions of the carrier. The assembly may be refurbished by simple replacement of the worn lining. The carrier and the lining may be formed as unitary annular members or as segments of annular members.
A friction disk comprising an annular carrier including a plurality of recessed regions and torque drive notches spaced around its circumferential direction, and a friction lining mounted on the carrier, the friction lining having a flat wear face and an obverse face including raised areas corresponding to and matingly engaging the walls of the recessed regions of the carrier to provide torque transfer capability between the lining and the carrier, the depth of the recessed regions being slightly less than the height of the raised areas.
A method of refurbishing a worn friction disk comprising an annular carrier including a plurality of recessed regions and torque drive notches spaced around its circumferential direction,, and a friction lining mounted on the carrier, the friction lining having a flat wear face and an obverse face including raised areas matingly engaging the walls of the recessed regions of the carrier to provide torque transfer capability between the lining and the carrier, the method comprising replacing the worn friction lining with new friction lining to provide a desired assembly thickness, the new friction lining having a flat wear face and an obverse face including raised areas matingly engaging the walls of the the recessed regions of the carrier to provide torque transfer capability between the lining and the carrier, the raised areas of the friction lining bearing the friction lining against a clamping load applied during a braking action.
A friction disk comprising an annular carrier including a plurality of recessed regions extending completely through the thickness of the carrier to define a plurality of window regions and torque drive notches spaced around its circumferential direction, and a pair of friction linings mounted on opposite sides of the carrier, each of the friction linings having a flat wear face and an obverse face including raised areas corresponding to and matingly engaging the walls of the recessed regions of the carrier to provide torque transfer capability between the linings and the carrier, the raised areas of one of the pair of friction linings bearing on the raised areas of the other of the pair of friction linings when mounted on the carrier.
