Embodiment Construction

[0028] figure 1 A longitudinal section through a centrifugal pendulum 10 with a damping device 15 according to the first embodiment is shown. figure 2 In the area of ​​the damping device 15 is shown the figure 1 A section of the longitudinal section shown in . image 3 shown in figure 2 An enlarged section of the damping device 15 shown in .

[0029] The centrifugal pendulum 10 is mounted rotatably about an axis of rotation 20 . In this case, the centrifugal pendulum 10 can be a component of a drive train and can be coupled by means of one of the components of the drive train. The centrifugal force pendulum 10 includes a pendulum flange 25 and a pendulum mass pair 30 . The pair of pendulum masses 30 includes a first pendulum mass 35 which is figure 1 Arranged on the left side of the pendulum flange 25. Furthermore, the pair of pendulum masses 30 includes a second pendulum mass 40 which is arranged opposite the first pendulum mass 35 on the right on the pendulum flange...

Abstract

The invention discloses a centrifugal force swing which is used for the automobile tranmission system. Described in the centrifugal force can swing around a rotation axis of rotation, among them, set up a place of the flange and at least one place for quality, among them, the pendulum is quality of including a first described in the quality and the quality of a second set of pendulum flange including outline with a gap of at least one gap, among them, the two place quality by means of at least one interval pin bolt connection, referred to at least one interval pin bolt is guided through the gap of described in the place of the flange, among them, it is between pin bolt set a damping device, among them, the hollow cavity structure is used to described in the above mentioned in hollow cavity structure and gap between contour tangent contact with hollow cavity structure inside and surrounded by the structure of the hollow cavity fluid exchange between.

Description

technical field [0001] The invention relates to a centrifugal force pendulum according to the features of claim 1 . Background technique [0002] Centrifugal pendulums are known which have a pendulum flange which can be coupled to other components of the drive train. The centrifugal pendulum includes at least one pendulum mass pair including a first pendulum mass and a second pendulum mass. The two pendulum masses are arranged opposite each other on both sides of the pendulum flange and are connected to one another by means of spacer pins. A recess is provided in the pendulum flange through which the spacer pin is guided. The pendulum masses are guided by guide means in order to perform a pendulum movement. In this case, the spacer pin may bear against a partial contour of the recess in the pendulum flange. This results in noise generation. In order to reduce this noise generation, a sleeve-shaped rubber element is arranged on the circumferential side of the spacer pin,...
