Torsional vibration damper
View Patent ↗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.
1. 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.
2. The torsional vibration damper as recited in claim 1 , wherein the pressure plate has an axial frictional surface in order to transfer the torque.
3. The torsional vibration damper as recited in claim 2 , wherein the spring is situated in a radially outer region of the pressure plate.
4. The torsional vibration damper as recited in claim 1 , wherein the strap extends inward in a radial direction.
5. The torsional vibration damper as recited in claim 1 , wherein:
the pressure plate has a plurality of straps extending from the pressure plate in the axial direction.
6. The torsional vibration damper as recited in claim 1 , wherein the pressure plate is made from a metal sheet.
7. The torsional vibration damper as recited in claim 1 , wherein the pressure plate has an encircling rim which extends in the axial direction.
8. The torsional vibration damper as recited in claim 1 , wherein the hub flange is set up to be moved axially on the output shaft while ending torque.
9. A torsional vibration damper, comprising:
a pressure plate having a strap extending from the pressure plate in an axial direction;
a 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:
connected to the holding plate;
located axially between the pressure plate and the holding plate; and,
having a cutout; and,
a plurality of centrifugal force pendulums distributed around a circumference of the pendulum flange, wherein the strap extends axially through the cutout.
