Abstract
A torsional vibration damper includes an input side for receiving a torque, an output side for dispensing the torque, an intermediate element arranged for torque transmission between the input side and the output side, an energy storage element supporting the intermediate element such that it can vibrate relative to the input side and the output side, and a roll body. The intermediate element has a transmission path for the roll body. The input side or the output side forms a path side with a counter path that is complementary to the transmission path, and the other of the input side or the output side forms a force side. The roll body is guided in a rotatable manner between the transmission path and the counter path, and the energy storage element connects the force side to the intermediate element for torque transmission.
