Abstract
A torsional vibration damper for transferring torque between a first and a second rotatable element, having a rotatable pressure plate to transfer the torque from the first element, a rotatable output element to transfer the torque to the second element, and a vibration damper element to transfer the torque between the pressure plate and the output element, where the vibration damper element includes an energy-storing spring system. A driving element is formed in a single piece on the pressure plate to fit against the spring system.
Claims9
A torsional vibration damper, comprising:
- a rotatable pressure plate having a strap extending from the pressure plate in an axial direction;
- a rotatable hub flange arranged to connect to an output shaft;
- a holding plate arranged to transfer torque to the rotatable hub flange;
- a spring circumferentially aligned with the strap to transfer the torque between the pressure plate and the holding plate;
- a pendulum flange located axially between the pressure plate and the spring, the pendulum flange connected to the holding plate and having a cutout;
- a plurality of centrifugal force pendulums distributed around a circumference of the pendulum flange, wherein the strap extends axially through the cutout in the pendulum flange.
