| 摘要 |
The invention relates to a vibration damper (1) for a torque transmission device for a motor vehicle, in particular intended for being arranged in a transmission chain, said vibration damper including: a first element (2) and a second element (3) rotatably movable relative to one another about an axis of rotation (X), a transmission member (4), supported by the second element (3), capable of transmitting a torque between the first element (2) and the second element (3) and of damping the rotation cycle irregularities between the first element (2) and the second element (3), the transmission member including a resiliently deformable blade (14) engaging with a bearing member (17) supported by the first element (2) so as to transmit a torque between the first element (2) and the second element (3), the damper (1) being characterised in that the transmission member (4) includes, in a section (S) passing through a plane containing the axis of rotation (X) of the damper, a bevel (5). |
