Abstract
Abstract A torsional vibration damper for a torque converter clutch has a plurality of elastomeric members disposed in drive relation between a clutch input member and a clutch output member. One end of the elastomeric members is pivotally connected to the clutch input and the other end of the elastomeric members is operatively connected to the output member through a cam surface. The elastomeric members, while transmitting torque, permit relative angular motion between the input and output members of the clutch to reduce the torsional vibrations imposed on the input member by an internal combustion engine.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
104 words
A single plate clutch and torsional vibration damper comprising; input means for accepting an input drive torque; output means for delivering a drive torque and having a plurality of cam reaction surfaces formed therein; and vibration damper means including a plurality of radially extending elastomeric band means each having one end pivotally connected to said input means and being rotatable therewith and another end drivingly connected to respective cam reaction surfaces on said output means for transmitting torque between the input means and the output means while said band means change length permitting relative angular movement between said input means and said output means.
Claim 2
Dependent Claim
104 words
A single plate clutch and torsional vibration damper comprising; input means for accepting an input drive torque; output means for delivering a drive torque and having a plurality of cam reaction surfaces formed therein; and vibration damper means including a plurality of radially extending elastomeric band means each having one end pivotally connected to said input means and being rotatable therewith and another end drivingly connected to respective cam reaction surfaces on said output means for transmitting torque between the input means and the output means while said band means change length permitting relative angular movement between said input means and said output means.
Claim 3
Dependent Claim
126 words
A single plate clutch and torsional vibration damper comprising; input drive transmitting means for accepting an input drive torque; output drive transmitting means for delivering a drive torque; a plurality of cam reaction surfaces formed on one of said drive transmitting means; and vibration damper means including a plurality of radially extending elastomeric band means each having one end pivotally connected to the other of said drive transmitting means and being rotatable therewith and another end drivingly connected to respective cam reaction surfaces on said one drive transmitting means for transmitting torque between the input drive transmitting means and the output drive transmitting means while said band means change length permitting relative angular movement between said input drive transmitting means and said output drive transmitting means.
Claim 4
Dependent Claim
126 words
A single plate clutch and torsional vibration damper comprising; input drive transmitting means for accepting an input drive torque; output drive transmitting means for delivering a drive torque; a plurality of cam reaction surfaces formed on one of said drive transmitting means; and vibration damper means including a plurality of radially extending elastomeric band means each having one end pivotally connected to the other of said drive transmitting means and being rotatable therewith and another end drivingly connected to respective cam reaction surfaces on said one drive transmitting means for transmitting torque between the input drive transmitting means and the output drive transmitting means while said band means change length permitting relative angular movement between said input drive transmitting means and said output drive transmitting means.
Claim 5
Dependent Claim
116 words
A single plate clutch and torsional vibration damper comprising; input means for accepting an input drive torque; output means for delivering a drive torque and having a plurality of cam reaction surfaces formed therein; and vibration damper means including a plurality of elastomeric band means extending radially between said input means and said output means, each band having one end drivingly connected to said input means and another end drivingly connected to respective cam reaction surfaces on said output means for transmitting torque between the input means and the output means while said band means change length accommodating relative angular movement between said input means and said output means thereby decreasing the torsional vibrations transmitted therebetween.
Claim 6
Dependent Claim
116 words
A single plate clutch and torsional vibration damper comprising; input means for accepting an input drive torque; output means for delivering a drive torque and having a plurality of cam reaction surfaces formed therein; and vibration damper means including a plurality of elastomeric band means extending radially between said input means and said output means, each band having one end drivingly connected to said input means and another end drivingly connected to respective cam reaction surfaces on said output means for transmitting torque between the input means and the output means while said band means change length accommodating relative angular movement between said input means and said output means thereby decreasing the torsional vibrations transmitted therebetween.
