REDUCED NOISE FLEXPLATE

摘要

A reduced noise flexplate assembly and method of construction is provided. The assembly includes a central plate that is generally disc shaped and extends radially from an axis. A ring gear is disposed annularly about the central plate and presents a plurality of ring teeth that extend radially therefrom for engaging a pinion gear coupled to a starter of an automobile. A noise plate is attached to the central plate with a plurality of plate fasteners and extends circumferentially about the axis. The noise plate includes a flange and a lower lip extending generally axially and radially outwardly from the inside flange to a maximum deflection zone adjacent to the ring teeth of the ring gear. The noise plate is frictionally engaged with and slideably moveable relative to the central plate and/or ring gear to reduce noise and reduce vibrations during starting of the automobile by converting friction into heat.

1. A flexplate assembly comprising;
a central plate having a general disc shape disposed about and extending radially from an axis, a ring gear annularly secured about said central plate and presenting an outer circumference defining a plurality of ring teeth extending therefrom, at least one noise plate disposed adjacent to said central plate and extending circumferentially about said axis for reducing vibrations and noise from said flexplate assembly, and said noise plate being frictionally engaged with and slideably moveable relative to said central plate for reducing noise and reduce vibrations by converting friction between said noise plate and said central plate into heat.
