Damper architectures

A torque converter assembly configured to transfer torque between a prime mover and an automotive transmission, the torque converter assembly comprising:

• an input member configured to transfer torque from the prime mover;
• an output member configured to transfer torque to the automotive transmission;
• a torque converter having a pump and a turbine, the pump being coupled to the input member;
• a lockup clutch having a driving element and a driven element, the driving element being coupled to the input member;
• and
• a torsional vibration damper comprising:
• a planetary gear set having a first node, a second node, and a third node;
• a first spring engagement element connected to one of the first, second, and third nodes, and a second spring engagement element connected to another of the first, second, and third nodes;
• at least one spring contacting both the second spring engagement element and the first spring engagement element and configured to permit the second spring engagement element to angularly deflect with respect to the first spring engagement element,
• wherein the turbine is coupled to the first node of the planetary gear set, the driven element of the lockup clutch is connected to the second node of the planetary gear set, and the output member is coupled to the third node of the planetary gear set.

A powertrain for a motor vehicle comprising:

• an engine configured to be disposed in the motor vehicle and having an engine output member;
• an automatic transmission selectively connected to the engine, the automatic transmission having a transmission input member;
• a torque converter assembly configured to transfer torque between the engine and the automatic transmission, the torque converter assembly comprising:
• a torque converter having a pump and a turbine, the pump being coupled to the engine output member;
• a lockup clutch having a driving element and a driven element, the driving element being coupled to the engine output member;
• and
• a torsional vibration damper comprising:
• a planetary gear set having a first node, a second node, and a third node;
• a first spring engagement element connected to one of the first, second, and third nodes, and a second spring engagement element connected to another of the first, second, and third nodes;
• and
• at least one spring contacting both the second spring engagement element and the first spring engagement element and configured to permit the second spring engagement element to angularly deflect with respect to the first spring engagement element,
• wherein the turbine is coupled to the first node of the planetary gear set, the driven element of the lockup clutch is connected to the second node of the planetary gear set, and the transmission input member is coupled to the third node of the planetary gear set.
