Problems solved by technology

Inhomogeneous angular velocities of the drive train (caused, for example, by the working stroke of the internal combustion engine) lead to a deflection of the centrifugal pendulum in the circumferential direction of the pendulum flange, thus attenuating the inhomogeneity of the angular velocities of the drive train

Embodiment Construction

[0024] figure 1 A top view of a known torsional vibration damper 100 is shown. The torsional vibration damper 100 comprises a first, essentially disc-shaped pendulum flange 200 with a centrally arranged hub 110 . The pendulum flange 200 can be set in rotational motion by the motor vehicle drive train via the hub 110 . figure 1 The direction of rotation 120 shown here corresponds to the viewing direction from the transmission arranged in the drive train of the motor vehicle to the internal combustion engine of the motor vehicle.

[0025] The torsional vibration damper 100 serves to damp torsional vibrations of the drive train. For this purpose, the torsional vibration damper 100 has a plurality of centrifugal pendulums 300 . exist figure 1 In the solution shown there are four centrifugal pendulums 300 , namely a first centrifugal pendulum 301 , a second centrifugal pendulum 302 , a third centrifugal pendulum 303 and a fourth centrifugal pendulum 304 . However, other number...

Abstract

A torsional vibration damper (1100) for a drivetrain of a motor vehicle comprises a substantially circular-disc-shaped pendulum flange (200) and a multiplicity of centrifugal force pendulums (300). Here, each centrifugal force pendulum comprises a first pendulum mass (320) and a second pendulum mass (330). The first pendulum mass is arranged above a first surface (230) of the pendulum flange, and the second pendulum mass is arranged above a second surface of the pendulum flange. The first pendulum mass and the second pendulum mass are rigidly connected to one another in each case by means of at least two spacer bolts (340). The pendulum flange has a multiplicity of recesses (210) in which the spacer bolts are guided. Here, a second spacer bolt (360) of a first centrifugal force pendulum (300) and a first spacer bolt (340) of a second centrifugal force pendulum (300) are guided in at least one first recess (210). Also arranged in the first recess is a spacer element (1200) dimensioned such that the first centrifugal force pendulum and the second centrifugal force pendulum cannot come into contact with one another.

Description

technical field [0001] The invention relates to a torsional vibration damper according to the preamble of claim 1 . Background technique [0002] Torsional vibrations can occur in the drive train of a motor vehicle. In order to dampen such torsional vibrations, it is known to use torsional vibration dampers arranged in the drive train. Such a torsional vibration damper or rotational vibration damper comprises an essentially disk-shaped pendulum flange, on which several centrifugal pendulums in the form of mass elements are mounted. The centrifugal pendulum is movable here in the radial direction and in the circumferential direction of the pendulum flange. [0003] The pendulum flange is set in a pivoting motion by a drive train. As a result, the centrifugal pendulum is pressed radially outward, wherein the magnitude of the outwardly acting centrifugal force depends on the rotational speed of the drive train. Inhomogeneous angular velocities of the drive train (caused, fo...
