REDUCED NOISE FLEXPLATE
DRIVE
May 25, 2016
A reduced noise flexplate assembly (20,120) and method of construction is provided. The assembly (20,120) includes a central plate (22) that is generally disc shaped and extends radially from an axis (A). A ring gear (26) is disposed annularly about the central plate (22) and presents a plurality of ring teeth (30) that extend radially therefrom for engaging a pinion gear coupled to a starter of an automobile. A noise plate (50) is attached to the central plate (22) with a plurality of plate fasteners (61) and extends circumferentially about the axis (A). The noise plate (50) includes a flange (52) and a lower lip (54) extending generally axially and radially outwardly from the inside flange (52) to a maximum deflection zone adjacent to the ring teeth (30) of the ring gear (26). The noise plate (50) is frictionally engaged with and slideably moveable relative to the central plate (22) and/or ring gear (26) to reduce noise and reduce vibrations during starting of the automobile by converting friction into heat.
