The invention concerns a torque damper arranged between two rotating elements, an input element (,) and an output element (,),comprising resilient members (,) with circumferential action, two guide washers (,) associated with (,) one of the elements and axially arranged on either side of a disc (,) associated with the other (,) element, the resilient members (,) operating between the two guide washers (,) and the disc (,) by being placed in windows (,) located one opposite the others arranged in the guide washers (,) and in the disc (,), said windows (,) having two side edges (,), on which are adapted to be urged to rest the ends of the resilient members (,) which form between them an angle (,) opening outward, the axis (,) of the resilient members (,) being a non-rectilinear curve with its concavity directed towards the common rotation axis of the input (,) and output (,) elements, such that the bearing surfaces of the ends of said resilient members (,) form between them the same angle (,).

Torque damper and damping device equipped with such a torque damper

The invention concerns a torque damper arranged between an input element and a rotating output element, and comprising resilient members (,), with circumferential action, two guide washers associated with one of the elements and axially arranged on either side of a disc associated with the other element, the resilient members (,) operating between the two guide washers and the disc, by being placed in windows (,), located opposite provided in the guide washers and in the disc. Said windows (,) have side edges (,) on which are adapted to be urged to rest the ends of the resilient members (,); the windows (,) of the two guide washers have an external edge (,) which has a portion offset inward (A), in a zone (,) not swept by the ends of the resilient members (,) during the relative travel in rotation, in one direction or the other, of the input and output elements, which portion (A) extends circumferentially in the shape of an arc whose center (,) is located towards the outside with respect to the rotation axis (,) of the input and output elements.
