Abstract
Abstract A clutch driven plate assembly for use in a vehicle or industrial application utilizing a torsional damping system with a high deflectional amplitude to connect the driving and driven members. The assembly includes a hub having oppositely disposed radially extending arms, a substantially central driven plate carrying the friction linings, and a pair of axially spaced spring retainers with openings receiving a series of helical springs. The driven plate has a pair of oppositely disposed elongated openings encompassing and abutting an adjacent pair of springs, and the hub arms receive the adjacent pair of springs therebetween and are in driving contact therewith.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
117 words
In a clutch plate assembly comprising a hub having a radial flange, a clutch driven plate carrying oppositely disposed friction facings, a pair of spring retainer plates axially spaced apart and encompassing said hub flange and clutch driven plate therebetween, said spring retainer plates having a plurality of axially aligned spring windows therein, and damper springs received in each aligned set of windows, the improvement comprising that said damper springs and windows are unequally spaced about the circumference of said plates, a pair of oppositely disposed radially extending hub arms located between pairs of adjacent damper springs, and said clutch driven plate having a pair of oppositely disposed elongated arcuate windows encompassing said pairs of damper springs.
Claim 2
Dependent Claim
117 words
In a clutch plate assembly comprising a hub having a radial flange, a clutch driven plate carrying oppositely disposed friction facings, a pair of spring retainer plates axially spaced apart and encompassing said hub flange and clutch driven plate therebetween, said spring retainer plates having a plurality of axially aligned spring windows therein, and damper springs received in each aligned set of windows, the improvement comprising that said damper springs and windows are unequally spaced about the circumference of said plates, a pair of oppositely disposed radially extending hub arms located between pairs of adjacent damper springs, and said clutch driven plate having a pair of oppositely disposed elongated arcuate windows encompassing said pairs of damper springs.
Claim 3
Dependent Claim
70 words
A clutch plate assembly as set forth in claim 1, in which a plurality of stop pins are secured in the axially spaced spring retainer plates, said clutch driven plate and hub arms having a pair of elongated arcuate slots therein receiving a pair of stop pins, and another pair of stop pins extending through the spacing between the hub arms and the arcuate elongated windows in the clutch plate.
Claim 4
Dependent Claim
40 words
A clutch plate assembly as set forth in claim 1, wherein said adjacent pairs of damper springs encompassed by the elongated arcuate windows in said clutch driven plate act in series when torque is applied to the clutch driven plate.
Claim 5
Dependent Claim
88 words
A clutch plate assembly as set forth in claim 1, in which four sets of damper springs are received in four axially aligned sets of spring windows with opposite pairs of spring windows being more closely spaced together and the outer ends of each pair of spring windows spaced farther apart to provide said unequal spacing, and the web portions between said elongated arcuate windows of said clutch driven plate and said hub arms are axially aligned and located in said farther spacing between the pairs of springs.
Claim 6
Dependent Claim
28 words
A clutch plate assembly as set forth in claim 4, wherein the pair of oppositely disposed elongated arcuate windows each encompasses a pair of closely spaced adjacent springs.
Claim 7
Dependent Claim
84 words
A clutch plate assembly as set forth in claim 5, in which four circumferentially equally spaced stop pins are secured to the spring retainer plates at locations between said damper springs, said web portions of the clutch driven plate and said hub arms having a pair of oppositely disposed axially aligned elongated arcuate slots receiving one pair of stop pins, the other pair of stop pins extending through the space between the hub arms and the elongated arcuate windows in the clutch driven plate.
Claim 8
Dependent Claim
45 words
A clutch plate assembly as set forth in claim 6, wherein said opposite pairs of damper springs encompassed by the elongated arcuate windows in the clutch driven plate act in series through the spring retainer plates when torque is applied to the clutch driven plate.
