Dependent claims

A vibration damper for a torque converter, comprising:

a first cover plate arranged to receive, from a lock-up clutch, a first rotational torque in a first rotational direction;
a second cover plate non-rotatably connected to the first cover plate and including a plurality of radially outwardly extending protrusions defining a first plurality of indentations;
an intermediate flange:
axially disposed between the first cover plate and the second cover plate;
and,
including a plurality of axially extending protrusions disposed in the first plurality of indentations, the axially extending protrusions having a greater axial length than an axial thickness of the intermediate flange;
and,
a plurality of springs directly engaged with the first cover plate, the second cover plate, and the intermediate flange.
