Title: TORSION DAMPER AND MOTOR VEHICLE
Abstract:
The present invention relates to a torsion damper (1) comprising: - a primary element (3) comprising a radial wall (3c); - a secondary element (7), the primary element (3) and the secondary element (7) being free to rotate relative to each other about an axis of rotation (X); - an elastic damping means configured to dampen the rotation acyclisms; - a web (9) rotationally coupled to the secondary element (7) and intended to come into contact with the elastic damping means, the rotational coupling between the web (9) and the secondary element (7) being implemented by rivets (12), the primary element (3) comprising at least one opening (30) in its radial wall (3b) to allow the web (9) to be riveted to the secondary element (7), the torsion damper (1) further comprising at least one obstruction element (32, 32') that comprises an overmoulded elastomer element (32b, 32') and that is configured to obstruct said at least one opening (30), said obstruction element comprising a deformable opening (33, 34) configured to allow the passage of a riveting tool (35).
