Embodiment Construction

[0124] figure 1 A device 1 for damping torsional oscillations according to a first variant of the first exemplary embodiment of the invention is shown.

[0125] The damping device 1 is of a swinging and oscillating body type. The device 1 can in particular be equipped with a motor vehicle transmission system, for example incorporated in a component (not shown) of such a transmission system, such as a dual mass flywheel, a hydraulic torque converter or a clutch disc.

[0126] The component may form part of a drive train of a motor vehicle comprising, in particular, a heat engine with two, three or four cylinders.

[0127] exist figure 1 , the device 1 is stationary, that is, it does not filter the torsional oscillations transmitted by the propulsion chain due to the rotational irregularities of the heat engine.

[0128] As known, such a component may comprise a torsional damper with at least one input element, at least one output element and a circumferentially acting elasti...

Abstract

The invention relates to a device (1) for damping torsional oscillations, comprising: at least one carrier (2) rotatable about an axis (X); a plurality of oscillating bodies (3), each oscillating body (3) relative to Said carrier (2) is movable; and a frictional connection (30) between two peripherally adjacent oscillating bodies (3).

Description

technical field [0001] The invention relates to a device for damping torsional oscillations, in particular for a drive train of a motor vehicle. Background technique [0002] In such applications, the means for damping torsional oscillations may be incorporated into a torsional damping system capable of selectively connecting the heat engine to the clutch of the gearbox in order to filter vibrations due to rotational irregularities of the engine. [0003] As a variant, in such applications, the means for damping torsional oscillations may be incorporated in the friction clutch disc or in the hydraulic torque converter. [0004] Such a device for damping torsional oscillations generally realizes a support and one or more oscillating bodies movable relative to the support, the displacement of the support relative to each oscillating body being guided by two rolling members, on the one hand with The rolling track integral with the support cooperates with the rolling track inte...
