Abstract: A torsional damping device (110) includes a movable torque input element (130, 140), a movable torque output element (150), at least one phasing member (320,340) and at least one group of elastic members (250, 260) mounted between the torque input element and torque output element. The at least one group of elastic members acts against rotation of the torque input element and the torque output element with respect to one another. The elastic members of the at least one group of elastic members are arranged in series by the at least one phasing member (320, 340) so that the elastic members of the at least one group of elastic members deform in phase with one another. The torque input element having at least one stop member (620) limiting rotation of the torque input elememt relative to the output element and relative to the at least one phasing member.

Abstract: A vibration damping device for a motor vehicle, features a first movable element (13, 14) and a second movable element (15, 16) both rotatable around an axis X, at least one group of elastic members (25, 26) mounted between the first movable element and the second movable element and acting against rotation of the first movable element and second element with respect to one another, and a phasing member (32, 33) rotationally movable around the axis X. The first movable element (13, 14) and the second movable element (15, 16) are coaxial and capable of transmitting a torque. The phasing member (32, 33) includes a first portion (32) and a second portion (33), for arranging the elastic members of the at least one group in series so that the elastic members of each group deform in phase with one another.

Abstract: A torsional damping device (4) includes a first movable element (13, 14) and a second movable element (15, 16), a central hub rotationally coupled to the second element, at least one group of elastic members (25, 26) acting against rotation of the first element and second element with respect to one another, a phasing member having by two parts (32, 33) for arranging the elastic members of the at least one group of elastic members (25, 26) in series so that the elastic members (25, 26) of the at least one group deform in phase with one another, and a pendulum damper (48) rotationally connected to the phasing member. The first and second movable elements (13-14, 15-16) are coaxial and rotationally movable around an axis X. The phasing member (32, 33) is centered on the central hub by means of a pendulum support member.
