Abstract
A centrifugal pendulum mechanism, in particular a trapezoidal centrifugal pendulum mechanism, for a damping device and/or a torque transmission device, in particular for a drive train of a motor vehicle, comprising a pendulum mass carrier, which can be rotated about a rotational axis (S) and on which a plurality of pendulum masses or pendulum mass pairs that can be moved relative to the pendulum mass carrier are provided in the circumferential direction, wherein two pendulum masses or pendulum mass pairs directly adjacent in the circumferential direction of the pendulum mass carrier are or can be mechanically coupled to each other by means of a damping element.
Claims7
A centrifugal pendulum device for a drivetrain of a motor vehicle, comprising:
- a pendulum weight carrier rotatable about a rotary axis and including:
- first and second pluralities of guide paths;
- and,
- first and second axial sides;
- a first pendulum weight located on the first axial side and including a third plurality of guide paths;
- a second pendulum weight:
- located on the first axial side;
- adjacent to the first pendulum weight in a first circumferential direction;
- and,
- including a fourth plurality of guide paths;
- first and second guide elements:
- disposed in respective guide paths included in the first and third pluralities of guide paths;
- and,
- displaceable within the respective guide paths included in the first and third pluralities of guide paths;
- third and fourth guide elements:
- disposed in respective guide paths included in the first and fourth pluralities of guide paths;
- and,
- displaceable within the respective guide paths included in the first and fourth pluralities of guide paths;
- a first lamella spring element disposed between the first and second pendulum weights in the first circumferential direction;
- a first pin:
- connecting the first lamella spring element to the first pendulum weight;
- passing through a first guide path included in the second plurality of guide paths;
- and,
- displaceable within the first guide path;
- and,
- a second pin:
- connecting the first lamella spring element to the second pendulum weight;
- passing through the first guide path;
- and,
- displaceable within the first guide path, wherein the first and second pendulum masses are displaceable with respect to the pendulum weight carrier.
