Torque transmission device has absorbing portion comprising centering unit that is inserted in recess provided in pendulum mass support

摘要

The torque transmission device (10) has an impeller, a turbine wheel and a torsional vibration damper (12). The absorbing portions (18,28) of the torsional vibration damper are in contact with energy storage elements (26,38) respectively. A centrifugal pendulum device (40) is provided with a pendulum mass support (42) that is in contact with absorbing portion (28). The centering unit provided in the absorbing portion (28) is inserted in a recess provided in the pendulum mass support.
