Abstract
A damped flywheel comprising two coaxial masses (1, 6) mounted for movement of one with respect to the other against the action of springs (150) and of a friction member (170), in which the inertia of the first mass (1) is increased by locating the resilient member (150) entirely inwardly, in the radial sense, of the friction face (125) of the clutch itself.

A damped flywheel comprising two coaxial masses (1, 6), mounted for movement of one with respect to the other against circumferentially acting resilient means (150) and against an axially acting friction means (170), with one of the masses, referred to as the first mass (1), being adapted to be mounted in rotation on a driving shaft (30), while the other mass (6), referred to as the second mass, comprises a reaction plate (161) offering a friction face (125) for a friction disc (127) which is adapted to be mounted in rotation on a driven shaft, wherein the resilient means (150) are disposed entirely radially inwardly of the inner periphery of the friction face (125) of the second mass (6) and the second mass (6) has an arched portion (160) for overlapping the resilient means installed on the first mass (1).
A damped flywheel comprising two coaxial masses (1, 6), mounted for movement of one with respect to the other against circumferentially acting resilient means (150) and against an axially acting friction means (170), with one of the masses, referred to as the first mass (1), being adapted to be mounted in rotation on a driving shaft (30), while the other mass (6), referred to as the second mass, comprises a reaction plate (161) offering a friction face (125) for a friction disc (127) which is adapted to be mounted in rotation on a driven shaft, wherein the resilient means (150) are disposed entirely radially inwardly of the inner periphery of the friction face (125) of the second mass (6), wherein the friction means (170) is disposed radially outwardly of the resilient means (150), the friction device (570) has a friction surface (203) disposed within a cavity (110) in the said first mass (1), on the surface of the latter that faces towards the said second mass (6), on which friction surface there is disposed a friction ring (105), the movements of which are governed by the said second mass (6) and on which there bears a thrust ring (106) which is urged elastically towards it by axially acting resilient means (107) and frictional engagement is obtained by engagement of at least one projecting element (171) formed by moulding on a facing surface of the second mass (6).
A damped flywheel comprising two coaxial masses (1, 6), mounted for movement of one with respect to the other against circumferentially acting resilient means (150) and against an axially acting friction means (170), with one of the masses, referred to as the first mass (1), being adapted to be mounted in rotation on a driving shaft (30), while the other mass (6), referred to as the second mass, comprises a reaction plate (161) offering a friction face (125) for a friction disc (127) which is adapted to be mounted in rotation on a driven shaft, wherein the resilient means (150) are disposed entirely radially inwardly of the inner periphery of the friction face (125) of the second mass (6) wherein the engagement is obtained by means of an internal flange (172) corresponding to the inner diameter of the friction ring to obtain meshing with a clearance.
