Spring retainer plate with lanced spring stops

A torsional vibration damper, comprising:

• an axis of rotation;
• a drive plate;
• an output flange;
• a spring retainer plate including:
• a first side facing in a first axial direction;
• a second side facing in a second axial direction opposite the first axial direction;
• a first plurality of spring stops, each spring stop in the first plurality of spring stops:
• formed of a same material forming a remainder of the spring retainer plate;
• extending from the first side at least partially in the first axial direction;
• including respective first and second circumferentially separated end surfaces separated, in the first axial direction, from the first side by first and second respective gaps;
• and,
• a first plurality of arc springs, each arc spring in the first plurality of arc springs engaged with the drive plate and the spring retainer plate and including:
• a respective first circumferential end engaged with a respective first end surface;
• and,
• a respective second circumferential end engaged with a respective second end surface, wherein:
• the spring retainer plate is arranged to:
• partially surround the first plurality of arc springs;
• retain the first plurality of arc springs in a radially outward direction;
• and,
• retain the first plurality of arc springs in the second axial direction.

A torque converter, comprising:

• an axis of rotation;
• a cover;
• an impeller;
• a turbine;
• a stator;
• a torsional vibration damper including:
• a drive plate;
• an output flange;
• a spring retainer plate including:
• a first side facing in a first axial direction away from the turbine;
• a second side facing in a second axial direction toward the turbine;
• first and second pluralities of holes:
• passing through material forming the spring retainer plate and connecting the first and second sides;
• and,
• aligned with each other in a circumferential direction;
• a first plurality of spring stops, each spring stop in the first plurality of spring stops:
• formed of a same material forming a remainder of the spring retainer plate;
• bounded, in the circumferential direction, by a respective pair of holes from the first and second pluralities of holes;
• and,
• extending from the first side at least partially in the first axial direction;
• and,
• a first plurality of circumferentially disposed arc springs engaged with the drive plate and the first plurality of spring stops;
• and,
• a lock-up clutch arranged to non-rotatably connect the cover and the drive plate, wherein:
• the spring retainer plate is arranged to partially surround the first plurality of arc springs and retain the first plurality of arc springs in a radially outward direction;
• and,
• in a cross-section, orthogonal to the axis of rotation, of said each spring stop in the first plurality of spring stops, the spring retainer plate is continuous.
