Embodiment Construction

[0142] figure 1 A pendulum damper is shown.

[0143] The damping device 1 is of the oscillatory pendulum type. The device 1 can in particular be arranged in a motor vehicle transmission system, for example incorporated into a component (not shown) of such a transmission system such as a dual mass flywheel, a torque converter, or a clutch of a clutch plate.

[0144] The component may form part of a drive train of a motor vehicle comprising an internal combustion engine, in particular having two, three or four cylinders.

[0145] exist figure 1 , the device 1 is idle, ie it is not filtering out the torsional vibrations transmitted by the drive train, which are caused by the aperiodicity of the internal combustion engine.

[0146] In a known manner, such a component may comprise a torsional damper with at least one input element, at least one output element and a circumferentially acting elastic return member inserted between the input element and the output element. between...

Abstract

A pendulum damping device (1) comprises: a support (2) able to rotationally move about an axis (X); at least one pendulum body (3); and at least one rolling member (11) guiding the movement of the pendulum body (3) relative to the support (2), the rolling member (11) cooperating, on the one hand, with at least one raceway (12) rigidly connected to the support (2) and, on the other hand, with at least one raceway (13) rigidly connected to the pendulum body (3), the rolling member (11) comprising: a first part (32) defining a first axial end; a second part (33) defining a second axial end; and aresilient element (30) disposed in the rolling member (11) so as to axially separate these two parts (32, 33) so that the rolling member (11) exerts an axial clamping force on one of the pendulum bodies (3) and the support (2) when the pendulum body (3) moves relative to the support (2).

Description

technical field [0001] The invention relates to a pendulum damper device, in particular for a motor vehicle drive train. Background technique [0002] In such applications, a pendulum damper device may be incorporated into a torsional damping system capable of selectively connecting an internal combustion engine to a clutch of a transmission in order to filter out vibrations due to acyclism of the engine. Such torsional damping systems are known, for example, as dual-mass flywheels. [0003] In a variant, in such applications, the pendulum damper device may be incorporated into the clutch disc of the clutch, or the torque converter. [0004] Such pendulum dampers conventionally implement a support and one or more pendulums moving relative to the support, the movement of each pendulum relative to the support being guided by two rolling members firmly connected to the A rolling track connected to the support engages with a rolling track firmly connected to the pendulum.
