Embodiment Construction

[0121] Figure 1a

[0122] Figure 1a and 1b The same pendulum damping device 1 is shown in the rest position. The device 1 can in particular be fitted to a motor vehicle driveline, eg integrated into a component of such a system, not shown. Such components are, for example, dual mass flywheels, torque converters, friction clutch discs, flywheels integrated with the crankshaft, wet or dry dual clutches, simple wet clutches and hybrid modules including electric machines.

[0123] In the example in question, the apparatus 1 includes:

[0124] - a support 2 capable of rotational movement about the axis X,

[0125] - a plurality of pendulum assemblies 3 movable relative to the support 2.

[0126] According to the exemplary embodiment of the invention described below, the support 2 is unique and made in one piece.

[0127] According to the example discussed, it will be seen that the device 1 comprises five pendulum assemblies 3 . The pendulum assembly 3 is circumferential...

Abstract

A pendulum damping device comprising: - a support (2) rotatable about an axis (X), - at least one pendulum (3) comprising axially spaced relative to each other and movable relative to the support (2) moving first and second pendulum masses (5), and - at least one rolling member, which guides the movement of the pendulum body (3) relative to the support (2), characterized in that the device also comprises an axial clamp A tightening device (35), which is arranged axially between the first pendulum mass and the second pendulum mass (5), is partly housed in an opening (36) formed in the support and is capable of locking the pendulum and the support Some relative motion is performed to rub the first and second pendulum masses (5).

Description

technical field [0001] The present invention relates to a pendulum damping device, in particular for a motor vehicle transmission system. Background technique [0002] In this application, the pendulum damping device may be incorporated into the torsional damping system of a clutch capable of selectively connecting the internal combustion engine to the gearbox in order to filter vibrations due to the acyclic nature of the engine. Such torsional damping systems are, for example, known as dual-mass flywheels. [0003] As a variant, in this application the pendulum damping device can be integrated into the friction disc of the clutch or into the torque converter. [0004] Such pendulum damping devices are usually implemented as a support and one or more pendulum assemblies movable relative to the support, the displacement of each pendulum assembly relative to the support being guided by two rolling elements, which are first connected to The supporting track integrated with th...
