Title: TORSION DAMPING DEVICE
Abstract:
The invention relates to a torsion damping device, comprising at least one torque input element, at least one torque output element and at least one group of resilient members (29, 30) mounted between the torque input and output elements, the resilient members (29, 30) of this group being arranged in series by means of at least one phasing member so that the resilient members (29, 30) of each group deform in phase, one relative to the other, about an axis of rotation (X) of the device, guide washers (31, 32) axially located on either side of the resilient members (29, 30) and together delimiting a volume in which said resilient members (29, 30) are housed, pendulum damping means comprising pendulum masses (39) movably mounted on the phasing member, characterised in that the phasing member is integral with or is formed, at least partly, by the guide washers (31, 32), the device comprising sealing means delimiting, with the guide washers (31, 32), a sealed volume in which the resilient members (29, 30) are housed.
