Embodiment Construction

[0087] figure 1 A dual mass flywheel 1 is shown as part of a drive train of a vehicle. The drive train also includes internal combustion engines with two, three or four cylinders.

[0088] The dual mass flywheel 1 comprises a primary flywheel 3 and a secondary flywheel 6 connected to the primary flywheel. The main flywheel 3 comprises a flange 5 and a ring gear 7 . The main flywheel may be fastened to the crankshaft of the internal combustion engine.

[0089] The secondary freewheel 6 comprises a flange 8 interacting with an elastic return member 9 . In the embodiment described, the elastic return member 9 is a spring. The spring 9 enables the rotational displacement of the secondary flywheel 6 about the axis X relative to the primary flywheel 3 .

[0090] figure 1 The flange 8 is shown riveted to the hub 10 of the secondary flywheel 6 . Hub 10 is splined to enable it to fit onto a shaft.

[0091] The dual mass flywheel 1 comprises means 22 for damping torsional oscill...

Abstract

A device (22) for damped torsion oscillation comprises at least one support part (24), at least one pendulum component (25) and at least one rolling member; the support part (24) can be rotated aroundan axis (X); the pendulum component (25) comprises at least one pendulum mass, and can be moved relative to the support part (24); each rolling member (11) is coordinated with at least one first raceway (12) limited by the support part (24), and at least one second raceway (13) limited by the pendulum component (25); the displacement, relative to the support part (24), of the pendulum component (25) is led by at least one of the rolling members (11); and the device comprises at least one friction member (11) carried by the pendulum component, and used for generating lag in all or partial relative displacement of the pendulum component and the support part.

Description

technical field [0001] The invention relates to a device for damping torsional oscillations, in particular for a motor vehicle driveline. Background technique [0002] In this application, the device for damping torsional oscillations can be integrated into a torsional damping system capable of selectively connecting the internal combustion engine to the clutch of the gearbox in order to filter vibrations due to engine irregularities. Such a system is, for example, a dual mass flywheel. [0003] As a variant, in this application, the device for damping torsional oscillations can be integrated in the friction disc of the clutch or in the torque converter, or integrated in the hybrid powertrain or associated with a flywheel rigidly connected to the crankshaft of the vehicle couplet. [0004] Such devices for damping torsional oscillations typically utilize a support and one or more pendulum assemblies movable relative to the support, the displacement of each pendulum assembl...
