Embodiment Construction

[0047] definition

[0048] Unless otherwise indicated,

[0049] "Axially" means "parallel to the axis of rotation X of the support";

[0050] "radially" means "along a transverse axis intersecting the axis of rotation of the support";

[0051] "Angularly" or "circumferentially" means "about the axis of rotation of the support".

[0052] Thickness is measured along the axis of rotation X unless otherwise stated.

[0053] By "centrifugal bearing force" is meant a bearing force having a component directed away from the axis X of rotation.

[0054] "Motor vehicle" refers not only to passenger vehicles but also to industrial vehicles, especially heavy goods vehicles, public transport vehicles and agricultural vehicles, but also to any transport used to transfer living things and / or objects from one point to another device.

[0055] "Oscillation body" means a mass mounted to oscillate on a support in response to non-cyclic operation of the vehicle's engine. The pendulum generall...

Abstract

A dry pendular damping device (10) comprising: - a support (12) movable in rotation about an axis (X) of rotation, - a pendular body (13), - a rolling member (40), defining a rolling surface suitablefor rolling on support tracks and pendular body tracks, so as to guide an oscillation of the pendular body (13) relative to the support (12), and lubricant. The dry pendular damping device is characterized in that the dry pendular damping device further comprises contact zones of the pendular body and the rolling body and / or the support, and particularly when the support rotates around the axis (X) of rotation, the lubricant is located on at least one of the contact zones and has a speed factor greater than or equal to 30000 NDm.

Description

technical field [0001] The invention relates to a dry swing damping device, in particular for a clutch of a motor vehicle, and to a torsional damping device comprising such a swing damping device. Background technique [0002] Swing dampers are commonly used to filter vibrations caused by non-cyclic operation of motor vehicle engines. The swing damping device is generally fixed rigidly by means of rivets to the phase washer of the torsional damping device, in particular a clutch, a torque converter or a wet or dry dual clutch. [0003] It generally comprises an annular support for rotational drive and a plurality of oscillating bodies mounted to oscillate on the support about an axis parallel to the axis of rotation of the support. The movement of the oscillating body relative to the support is usually guided by two rolling members, each cooperating with a rolling track of the support and a rolling track of the oscillating body. The rolling tracks of the support and of the...
