Embodiment Construction

[0017] The specific implementation of the centrifugal pendulum damper according to the present invention will be described below in conjunction with the accompanying drawings. The following detailed description and drawings are used to exemplarily illustrate the principle of the present invention. The present invention is not limited to the described preferred embodiments, and the protection scope of the present invention is defined by the claims.

[0018] figure 1 A front view and a partial cross-sectional view of a centrifugal pendulum damper according to an embodiment of the present invention are shown in FIG. In this embodiment, the centrifugal pendulum shock absorber includes a pendulum flange 10 and a plurality of pendulum masses 20. The pendulum flange 10 is composed of two ring-shaped members-a base plate 12 and a cover plate 13, the base plate 12 and The cover plate 13 is fixed together with the axis of rotation, and defines an annular space 14 open toward the radial out...

Abstract

The invention relates to a centrifugal pendulum damper. The centrifugal pendulum damper comprises a pendulum flange, at least one pendulum mass piece and a pre-tightening force spring. The pendulum flange can rotate around the rotating axis, the at least one pendulum mass piece is arranged on the pendulum flange in the peripheral direction, and each pendulum mass piece can move relative to the pendulum flange along a preset track, wherein the pre-tightening force spring is an annular diaphragm spring in butt joint with the portion between the single pendulum mass piece and the pendulum flangein the axial direction, and when observing is carried out in the axial direction, the pre-tightening force spring is completely covered with the pendulum flange and the corresponding pendulum mass piece. The centrifugal pendulum damper has the stable pre-tightening force for the pendulum mass pieces.

Description

Technical field [0001] The invention relates to the technical field of shock absorbers. Specifically, the present invention relates to a centrifugal pendulum shock absorber with stable preload. Background technique [0002] Motor vehicles will still be driven by internal combustion engines in the foreseeable future. No matter what type of transmission is selected, the basic requirements for torque transmission between the engine and the transmission are the same, that is, torsional vibration and rotation unevenness should be reduced while starting and transmitting the average torque. Therefore, various damping devices are usually required in the drive train of the vehicle. The centrifugal pendulum shock absorber is a common type of vibration damping device. It installs a number of movable pendulum masses on a rotatable pendulum flange, and buffers torsional vibration through the swing of the pendulum mass under centrifugal force. effect. [0003] In order to improve the cushion...
