Friction plate for hydro kinetic clutch has gap defining areas of clutch friction lining for engagement

摘要

The friction disc for a hydro kinetic clutch (28) connecting driven and driving shafts has a friction lining (G) fixed to the disc with a friction face (50) transverse to the disc axis to frictionally engage with a complementary face of a clutch. The friction face has a gap (56) to radially separate an authorized contact surface to engage the complementary clutch surface and a non-contact face. Claims include a clutch using the disc and a method of load regulation using the clutch
