Embodiment Construction

[0017] figure 1 A schematic illustration of a device 100 for transmitting torque about an axis of rotation 105 is shown. The device 100 includes a centrifugal pendulum 110 with a pendulum flange 115 and a pendulum mass 120 . The pendulum mass 120 can comprise two pendulum elements 125 which are arranged on different axial sides of the pendulum flange 115 and are connected to each other. Pendulum mass 120 is displaceable on a pendulum rail in a plane of rotation about axis of rotation 105 relative to pendulum flange 115 . In addition, a braking element 130 is provided, which can be pressed axially against the pendulum mass 120 or against one of the pendulum elements 125 in order to limit or prevent the relative movement of the pendulum mass 120 . The mobility of the pendulum flange 115 . The braking element 130 is preferably connected to the pendulum flange 115 in a rotationally fixed manner. A friction element 135 can be arranged between the braking element 130 and the pen...

Abstract

A device for transmitting torque comprises a centrifugal force pendulum having a pendulum flange and pendulum mass. The pendulum flange can be supported by rotating about a rotational axis, and the pendulum mass can be mounted on the pendulum flange by moving in a plane of rotation. The device for transmitting the torque further comprises a brake element which can be pressed against the pendulum mass in the axial direction for braking the pendulum mass.

Description

technical field [0001] The invention relates to a device for transmitting torque, in particular in a drive train of a motor vehicle. Background technique [0002] A drive train is provided in a motor vehicle for connecting the drive motor to the drive wheels. Rotational motion is transmitted through the drive train, which may experience inhomogeneities, for example due to the configuration of the drive motor or due to uneven terrain. This inhomogeneity can affect the traction or driving behavior of the motor vehicle or can cause acoustic disturbances. Therefore, various measures are usually taken to isolate, eliminate or reduce this inhomogeneity. [0003] Measures for eliminating inhomogeneities in the transmitted rotational movement include a centrifugal pendulum with a pendulum flange and a pendulum mass mounted displaceably on the pendulum flange. The pendulum flange is arranged rotatably about an axis of rotation and follows the rotational movement of the drive train...
