Power transfer apparatus having a vibration dampening mechanism which provides structural support for the apparatus

摘要

A power coupling mechanism includes a flexible disk-like plate, a ring element, first and second input plates and a driven plate. The ring element is coupled to an outer radial portion of the flexible plate. The input plates are formed of deformed sheet metal material to at least partially define a viscous fluid filled chamber that encloses a dampening mechanism. The input plates are fixed to the ring element and the flexible plate such that center and inner radial portions of the flexible plate are axially spaced from the input plates to permit axial flexing. The driven plate at least partially extends into an annular housing of the dampening mechanism and has grooves interfitting with protrusions of the annular housing to provide structural support against thrust and radial forces. An inertia element with a ring gear is preferably connected to the driven plate.
