ABSTRACT:
A vibration damper for a torque converter clutch has elastomeric bands disposed to transmit torque between the clutch input member and the clutch output member while simultaneously permitting relative angular movement between the members to reduce the torsional vibration imposed on the input member. The elastomeric bands are connected to a clutch pressure plate and a gear member which is rotatably mounted on the pressure plate and meshes with a gear drivingly formed on the output member. The input member and output member undergo angular excursions relative to each other during torque transmission such that the gear member rotatably mounted on the pressure plate rotates due to its meshing engagement to increase the stress in the elastomeric band to a value commensurate with the torque transmitting level of the clutch. The torque input to the clutch is thus transmitted through the elastomeric band and the meshing gears to the clutch output member.
