Embodiment Construction

[0020] figure 1 Shown is a centrifugal pendulum 100 which is provided in particular for use in a drive train of a motor vehicle. Centrifugal pendulum 100 comprises a pendulum flange 105 , which is mounted rotatably about an axis of rotation 110 , and a pendulum mass 115 mounted on the pendulum so that it can move in a plane of rotation about the axis of rotation 110 . on flange 105. Pendulum mass 115 is shown transparently to better illustrate its support on pendulum flange 105 . In the illustrated embodiment, the pendulum mass 115 comprises two pendulum elements 120 which are mounted on different axial sides of the pendulum flange 105, but other embodiments are also possible, for example with respect to the pendulum method Lan 105 is an asymmetrical embodiment.

[0021] The pendulum elements 120 are connected to one another by means of one or more pins 125 . Each pin 125 extends axially through a corresponding recess 130 of the pendulum flange 105 . In this case, the del...

Abstract

The invention relates to a centrifugal force pendulum (100) comprising at least one pendulum flange (105) which is mounted in such a way so as to be rotatable about an axis of rotation (110), a pendulum mass (115) which is mounted on the pendulum flange (105) in such a way so as to be movable in the plane of rotation, and an impact damper (135) mounted on the pendulum mass (115) and used for limiting a pendulum trajectory of the pendulum mass (115). The impact damper (135) is mounted in such a way as to be rotatable about an axis (140) of its own which is parallel to the axis of rotation (110) of the pendulum flange (105).

Description

technical field [0001] The invention relates to a centrifugal pendulum for use in a drive train of a motor vehicle. In particular, the invention relates to a centrifugal pendulum having a stop damper for delimiting a pendulum path of a pendulum mass of the centrifugal pendulum. Background technique [0002] The centrifugal pendulum is provided to dampen rotational vibrations that may be superimposed on the rotational movement of the drive shaft. Especially in the drive train of a motor vehicle, reciprocating piston internal combustion engines can generate rotational vibrations in different operating states, which are advantageously directed towards the The drive wheel direction is damped before passing further. Rotational vibrations can also arise due to rotational inhomogeneities in the region of the drive wheels and are advantageously damped before they are transmitted via the drive train to the drive motor. [0003] The centrifugal pendulum comprises a pendulum flange ...
