ABSTRACT:
A torque converter clutch and vibration damper has a selectively engageable pressure plate with an internally toothed gear secured thereto. A plurality of pinion gear members are rotatably mounted on an output hub and mesh with the internally toothed gear. Each pinion gear has one end of a link member pivotally mounted thereon. The other end of each link member is connected to a pin which is guided in a radial slot and operatively connected with an elastomeric belt member. Relative angular excursion between the pressure plate and the output hub, caused by torque transmission, results in relative motion between the meshing gears so that the pin connected to each link member is moved radially outward in the slots formed in the output hub. The pin movement causes a change in the length of the elastomeric belt operatively connected therewith so that a change in the torque capacity of the vibration damper occurs.
