Problems solved by technology

However, the disadvantage here is that when the stroke piston engine of the drive train stops, the pendulum mass stops in the link guide against an end stop and thus produces a crashing noise

Embodiment Construction

[0019] figure 1 A detail of a cross section of centrifugal pendulum 10 is shown in the first operating state. In this case, the centrifugal pendulum 10 can be a component of the drive train of the motor vehicle and is designed to at least partially dampen the torsional vibrations generated by the four-stroke piston engine of the drive train.

[0020] In the first operating state, the centrifugal pendulum 10 is at rest or rotates about the axis of rotation 15 at a speed n which is less than the limit speed n G . The centrifugal pendulum 10 comprises a pendulum flange 20 , a pendulum mass 25 and a link guide 30 . The pendulum mass is coupled to the pendulum flange 20 by means of a link guide 30 . The link guide 30 guides the pendulum mass 25 in a pendulum movement along the pendulum track, so that the pendulum mass 25 is movable in a restricted manner relative to the pendulum flange 20 . The pendulum mass 25 includes a first pendulum mass 35 and a second pendulum mass 40 . ...

Abstract

A centrifugal pendulum supportable for rotation about an axis of rotation, including a pendulum flange, a pendulum mass, and a cam guide. The pendulum mass includes a first pendulum mass part and a second pendulum mass part. The first and second pendulum mass parts are coupled to be jointly movable with the pendulum flange along a pendulum path to a limited extent. A locking device is provided, the locking device coupling the first pendulum mass part and the second pendulum mass part. The locking device is capable of locking the first pendulum mass part relative to the second pendulum mass part.

Description

technical field [0001] The invention relates to a centrifugal force pendulum. Background technique [0002] Centrifugal pendulums with pendulum masses, pendulum flanges and link guides are known. In this case, the link guide couples the pendulum mass to the pendulum flange and guides the pendulum mass along the pendulum track when torsional vibrations are introduced into the centrifugal pendulum. However, it is disadvantageous in this case that when the piston engine of the drive train stops, the pendulum mass stops in the link guide against an end stop and thus produces a rattling noise. Contents of the invention [0003] The object of the present invention is to provide an improved centrifugal pendulum. [0004] According to the invention it was found that an improved centrifugal pendulum can thus be provided, ie the centrifugal pendulum is mounted rotatably about an axis of rotation and has a pendulum flange, a pendulum mass and a link guide. The pendulum masses are ...
