Problems solved by technology

Axial stop components of this type are therefore expensive and fragile to implement
In fact, the weight resting on these flanges can cause premature wear and even fracture of these flanges

Embodiment Construction

[0078] exist figure 1 The above shows a shock absorber device 1 according to an embodiment of the present invention. The damping device 1 is of the pendulum vibrator type.

[0079] The device 1 can be equipped, in particular, with a transmission of a motor vehicle, for example integrated in a torsional damper (not shown).

[0080] It is known that a torsional damper of this type comprises at least one input element, at least one output element and circumferentially acting elastic elements interposed between said input element and output element.

[0081] In the aforementioned case applied to a transmission of a motor vehicle, the input element is intended to be driven in rotation by a not shown drive shaft, such as the crankshaft of a motor vehicle internal combustion engine equipped with a transmission, while the output element is rotatably connected to a not shown slave A driven shaft, such as an input shaft of a motor vehicle gearbox coupled to a ratio switching member. ...

Abstract

Shock absorbing device (1), comprising: a support (2) rotatable about an axis (X), the support defining a guideway (30); at least one first (3) and at least one second (4) Weights, they can move relative to the support, the first and second counterweights are axially spaced relative to each other, and are respectively arranged on both sides of the support; at least one connecting piece (5) is used to connect the first and second a counterweight, a link rigidly coupled to the first and second counterweights, extending partially in an opening (25) provided in the support, the link defining a guideway (21); at least one guide ( 6), used to guide the counterweight relative to the support, the guide can move relative to the support and the counterweight, and can cooperate with the guideway defined by the support and the guideway defined by the connecting piece to guide the counterweight; the first and at least one of the second weights carries an interposer member (50) comprising a portion (51) axially disposed between the weight and the guide.

Description

technical field [0001] The invention relates to a shock absorbing device, especially for a transmission mechanism of a motor vehicle. Background technique [0002] In such applications, the damping device can be integrated into a torsional damping system capable of selectively connecting the engine to the clutch of the gearbox to filter vibrations originating from engine acyclismes. [0003] The damping device is of the pendulum type comprising a support and at least one pair of counterweights free to oscillate about a nominal axis parallel to the axis of rotation of the engine shaft. [0004] Patent application FR 2 981 714 describes an example of this type of damping device. According to this device, the two weights of the same pair are guided relative to the support by means of guides connected with the guideway defined by the support and by the connection means securing the weights of the pair. The other guideway defined cooperates. [0005] The guide is interposed ax...
