Torsional vibration damper with a rotational axis for a powertrain

A torsional vibration damper with a rotational axis for a powertrain of a motor vehicle, comprising:

• an input side for receiving a torque;
• an output side for outputting the torque;
• a first rolling body;
• a second rolling body;
• an intermediate element arranged for torque transmission between the input side and the output side, the intermediate element comprising:
• a first transmission path for rolling the first rolling body;
• and
• a second transmission path for rolling the second rolling body;
• and
• a first energy storage element for supporting the intermediate element in an oscillating manner, wherein:
• the input side comprises a first counter path complementary to the first transmission path;
• the output side comprises a second counter path complementary to the second transmission path;
• the first rolling body is guided in a rolling manner between the first transmission path and the first counter path;
• the second rolling body is guided in a rolling manner between the second transmission path and the second counter path;
• and
• the first energy storage element is arranged with a vector component that acts on the intermediate element in a circumferential direction.
