Abstract
A torsional vibration damper includes an input side and an output side, first and second rolling bodies, an intermediate element for torque transmission between the input and output sides, and an energy storage element for supporting the intermediate element in an oscillating manner. The intermediate element has a first transmission path for rolling the first rolling body, and a second transmission path for rolling the second rolling body. The input side has a first counter path complementary to the first transmission path. The output side has a second counter path complementary to the second transmission path. The first rolling body is guided between the first transmission path and the first counter path, and the second rolling body is guided between the second transmission path and the second counter path. The energy storage element is arranged with a vector component that acts circumferentially on the intermediate element in a circumferential direction.
