Abstract
A flexplate assembly comprising a central plate having a general disc shape disposed about and extending radially from an axis. The central plate has a first radial width. A ring gear is annularly secured about the central plate and presents an outer circumference that defines a plurality of ring teeth extending therefrom. At least one noise plate is disposed adjacent to the central plate and extends circumferentially about the axis for reducing vibrations and noise from the flexplate assembly. The noise plate has a second radial width that is at least one half of the first radial width of the central plate. A method of constructing such a flexplate assembly is also provided.
Claims22
A flexplate assembly comprising;
- a central plate having a general disc shape disposed about and extending radially from an axis, said central plate having a first radial width,
- a ring gear annularly secured about said central plate and presenting an outer circumference defining a plurality of ring teeth extending therefrom, and
- 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,
- wherein said noise plate has a second radial width being at least one half of said first radial width of said central plate, wherein said central plate defines a plurality of slots, and wherein said ring gear defines a plurality of apertures in axial alignment with said slots.
A flexplate assembly adapted to be connected to a shaft, comprising:
- a central plate having a first surface and a second surface and defining a first flange terminating in a ring gear, a second flange, and an angled intermediate segment interconnecting the first and second flanges;
- a hub secured to the first surface of the central plate on the second flange and adapted for driven connection to the shaft;
- and
- a noise plate disposed adjacent to and frictionally engaging at least one of the first and second flanges of the central plate.
- wherein the noise plate has a noise plate radial dimension that is at least one-half of a central plate radial dimension of the central plate.
A flexplate assembly comprising:
- a central plate having a general disc shape disposed about and extending radially from an axis, said central plate defining a top surface and a bottom surface with said top surface configured to be connected to a hub of a driveshaft, and said central plate having a first radial width;
- a ring gear annularly secured about said central plate and presenting an outer circumference defining a plurality of ring gear teeth extending therefrom;
- and
- at least one noise plate disposed adjacent to said central plate and extending circumferentially about said axis for reducing vibration and noise from said flexplate assembly,
- wherein said at least one noise plate includes a first noise plate underlying said bottom surface of said central plate and a second noise plate overlying said top surface of said central plate, and wherein said first and second noise plates each have a second radial width being at least one half of said first radial width of said central plate.
A flexplate assembly comprising:
- a central plate having a general disc shape disposed about and extending radially from an axis, said central plate including a first flange extending transversely to said axis and terminating at said ring gear, a first angled portion extending radially inwardly and axially from said first flange, and a second flange extending transversely to said axis from said first angled portion, said central plate having a first radial width;
- a ring gear secured about said central axis and presenting an outer circumference defining a plurality of ring gear teeth extending therefrom;
- and
- a noise plate disposed adjacent to said central plate and extending circumferentially about said axis for reducing vibration and noise from said flexplate assembly,
- wherein said noise plate has a second radial width being at least one half of said first radial width of said central plate, wherein said central plate further includes a first lower lip extending axially and radially outwardly form said first flange, and wherein said first lower lip includes a first axial portion extending axially away from said first flange and a first radial portion extending transversely to said axis from said first axial portion and terminating at said ring gear.
