Embodiment Construction

[0023] figure 1 A mass damper with a centrifugal pendulum 100 is shown. The centrifugal pendulum 100 includes a pendulum flange 105 which is arranged rotatably about an axis which transmits torque in a drive train. The drive train may include, inter alia, the drive motor and the transmission of the vehicle. Centrifugal force pendulum 100 also comprises four pendulum masses 110, in figure 1 Only three of them are fully shown in . Each pendulum mass 110 includes two mass elements 115 which are situated on different axial sides of the pendulum flange 105 . On the upper pendulum mass 110 , the mass element 115 facing the observer has been removed for a clearer illustration.

[0024] The mass elements 115 of each pendulum mass 110 are fixed on the pendulum flange 105 by means of a central link guide 120 , two inner link guides 125 and two outer link guides 130 in such a way that the pendulum masses 110 can Pivots in the plane of rotation of the pendulum flange 105 . Each link...

Abstract

The pendulum has a pendulum mass (110) including two mass elements (115), which lie on different axial sides of a pendulum flange (105) and are connected with each other by bolts (135). The bolts extend through an opening into the flange. The bolts together with the opening produce a limitation of pivotability of the mass relative to the flange. Elastic elements (160) are arranged between a radial surface of the bolts and the mass elements for damping the mass elements during impact of the bolts at a boundary of the opening.

Description

technical field [0001] The invention relates to a centrifugal force pendulum. In particular, the invention relates to a spring element for damping a pendulum mass when it is abutted against a pendulum flange of a centrifugal pendulum. Background technique [0002] Torsional vibration dampers are used in the drive train of a motor vehicle to damp torsional vibrations which may be caused, inter alia, by uneven torque variations of the drive motor. In particular, the torsional vibration damper can be arranged between the drive motor and the transmission. [0003] To counteract torsional vibrations, the torsional vibration damper comprises a centrifugal pendulum comprising a pendulum flange and at least one pendulum mass, which is pivotable relative to the pendulum flange in a plane of rotation. In certain operating states of the drive train, for example when the drive motor is at a standstill or when changing gears, the pendulum mass can be accelerated so strongly that it hit...
