Centrifugal pendulum mechanism

Abstract

The invention relates to a centrifugal pendulum mechanism, comprising at least one pendulum mass support and at least one pendulum mass arranged thereon, which pendulum mass can be moved to a limited extent radially relative to the pendulum mass support by means of at least one rolling element inside raceways formed by recesses in the pendulum mass support and the pendulum mass and in the circumferential direction, the rolling element having a guiding means formed in the gap between the individual pendulum mass and the pendulum mass support.; The invention is characterized in that means for reducing the gap size between the pendulum mass and the pendulum mass support in an at least spatially limited manner are provided outside the raceways for the rolling element and outside the range of the intermediate space between the pendulum mass and the pendulum mass support that can be covered by the guiding means during the rolling motion of the rolling element.

Description

technical field [0001] The invention relates to a centrifugal force pendulum device, comprising at least one pendulum mass support and at least one pendulum mass arranged on the pendulum mass support, which runs on a running track formed by the pendulum mass support and the hollow groove in the pendulum mass support by means of at least one rolling element The inner part is movable to a limited extent in the radial direction and in the circumferential direction relative to the pendulum mass carrier, the rolling element having a guide means formed in the gap between the individual pendulum mass and the pendulum mass carrier. Background technique [0002] Speed-adapted vibration dampers are used in the drive train to damp vibrations over a wide, preferably the entire drive engine speed range. This type makes it possible to damp the rotational oscillations over a large rotational speed range, ideally over the entire rotational speed range of the drive machine, wherein these are...

AI Technical Summary

Problems solved by technology

However, the resulting relatively large gap distances between the surfaces of the individual pendulum masses pointing towards the pendulum mass support and the pendulum mass support can lead to a tipping of the pendulum mass relative to the pendulum mass support, which is particularly the case at lower rotational speeds and thus Small centrifugal forces will indicate an obvious problem

The functioning of the centrifugal pendulum is therefore impaired in this speed range and cannot be reliably reproduced for recovery conditions

In addition, this tipping can lead to damage to the individual components and the connection of the pendulum mass to the pendulum mass support and its pivot support.
