Embodiment Construction

[0068] In the description and claims, the terms "outer" and "inner" and the orientations "axial" and "radial" will be used to refer to elements of a torque transmitting device according to the definitions given in the description. By convention, a "radial" orientation is orthogonal to the axis of rotation X of the torque transmitting device defining an "axial" orientation, while a "circumferential" orientation is orthogonal to the axis X and orthogonal to the radial direction. The terms "outer / outer" and "inner / inner" are used to define the relative positions of the various elements with reference to the axis of rotation X of the torque transmitting device; thus, an element near the axis X is defined by being opposed to a radially peripheral outer or outer part. Identified as inside or inside. Likewise, the terms "rear" (R) and "front" (F) are used to define the relative positions of the various elements in the axial direction, wherein elements intended to be placed close to t...

Abstract

The invention relates to a torque transmission device (1) with a torque limiter. The torque limiter comprises an input element (4); an output element (6); a pressure member (5) arranged to axially press one of the input element (4) and the output element (6) against the other of the input element (4) and the output element (6), wherein the torque transmission device further comprises a dynamic vibration absorber (9) comprising a support disc (28) and one or more inertial masses (29) mounted on the support disc (28) in an oscillating manner; the input element (4) and the output element (6) of the torque limiter can transmit torque to a support disc (28) by friction under the action of the pressure members (5, 27), and the support disc (28) can rotate about a rotation axis X relative to theinput element (4) and the output element (6) of the torque limiter.

Description

technical field [0001] The present invention relates to the field of torque transmission devices for motor vehicles, and more particularly to a torque transmission device equipped with a torque limiter and a dynamic shock absorber, such as an oscillating device. Background technique [0002] In the prior art, for example in document EP2765331, torque transmission devices are known comprising an input element intended to be fixed in rotation to a drive shaft and an output element intended to be fixed in rotation to a driven shaft. The torque transmitting device also includes a web interposed between the input member and the output member. The web is rotatably connected to the input element by elastic members. This web is also coupled to the output member via a torque limiter. Furthermore, a dynamic vibration absorber, for example of the pendulum type, is mounted on the output element of the torque transmission device, comprising a support and a pendulum mass mounted in an o...
