A device (10) for damping torsion between a clutch element (16) and a transmission shaft, comprising: an input washer (12A, 12B) that is rotationally integral with the clutch element (16); two output webs (18A, 18B) that are rotationally integral with the transmission shaft by means of a central hub (20); a pair of circumferentially acting elastic members (42) that are interposed circumferentially in series between the input washer (12A, 12B) and the output web (18A, 18B); a phase washer (44) that is interposed circumferentially between the two elastic members (42) of said pair. |

1. A device (10) for damping torsion between a clutch element (16) and a transmission shaft, the device (10) comprising:
an input washer (12A, 12B) that is rotationally integral with the clutch element (16) around the axis (B) of the transmission shaft; an output web (18A, 18B) that is rotationally integral with the transmission shaft by means of a central hub (20); at least one pair of circumferentially acting elastic members (42) that are interposed circumferentially in series between the input washer (12A, 12B) and the output web (18A, 18B); at least one phase washer (44) that is mounted rotatably around the axis (B) of the transmission shaft and is interposed circumferentially between the two elastic members (42) of said pair, said output web comprising a pair of output web elements (18A, 18B) that are arranged axially on either side of the input washer (12A, 12B), and wherein each input washer (12A, 12B) has a central orifice that is demarcated by an inner edge (34), the input washer (12A, 12B) being rotationally guided by sliding of its inner edge (34) on a cylindrical guidance face (36) that is rotationally integral with the central hub (20), said guidance face (36) having at least two radial stop faces (60, 62), each of which is capable of interacting with an associated radial stop face (69, 71) that extends from the inner edge (34) of the input washer (12A, 12B) in order to limit, in both directions, the rotation of the input washer (12A, 12B) with respect to the output web (18A,18B), and wherein the elastic members (42) are arranged in series on the circumference of a single circle having an axis (B). |
