Abstract
Abstract A friction clutch comprises a first part and a second part. The first part comprises two carrier plates coupled together at a fixed axial spacing by means of spacers. The second part includes a damper plate disposed axially between the two carrier plates. The first part further includes a first friction disc and a second friction disc, of which at least the first includes a support plate which is mounted so as to be axially movable with respect to one of the carrier plates, by virtue of openings formed in the support plate with the spacers passing through these openings. A coupling device is provided, coupling the support plate to the carrier plate with respect to which it is axially movable. The support plate is disposed axially between the two carrier plates. The invention is applicable to sports cars.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
162 words
A friction clutch, particularly for a sports car, comprising a first part and a second part, means mounting said first and second parts for their rotation relative to each other, said means including circumferentially acting resilient means, said first part comprising a first carrier plate, a second carrier plate, and spacer means coupling the said carrier plates together at a fixed axial spacing, said second part comprising a damper plate disposed axially between the carrier plates, said first part further comprising a first friction disc and a second friction disc, said first friction disc comprising a support plate having through openings, the spacer means extending through said openings whereby the said support plate is axially movable with respect to said first carrier plate, the friction clutch further including coupling means coupling the support plate to said first carrier plate, and being characterised in that the support plate of said first friction disc is disposed axially between said first and second carrier plates.
Claim 2
Dependent Claim
162 words
A friction clutch, particularly for a sports car, comprising a first part and a second part, means mounting said first and second parts for their rotation relative to each other, said means including circumferentially acting resilient means, said first part comprising a first carrier plate, a second carrier plate, and spacer means coupling the said carrier plates together at a fixed axial spacing, said second part comprising a damper plate disposed axially between the carrier plates, said first part further comprising a first friction disc and a second friction disc, said first friction disc comprising a support plate having through openings, the spacer means extending through said openings whereby the said support plate is axially movable with respect to said first carrier plate, the friction clutch further including coupling means coupling the support plate to said first carrier plate, and being characterised in that the support plate of said first friction disc is disposed axially between said first and second carrier plates.
Claim 3
Dependent Claim
40 words
A friction clutch according to claim 1, wherein the said second friction disc is disposed axially between the said carrier plates, and characterised in that an intermediate pressure plate is interposed axially between the said first and second friction discs.
Claim 4
Dependent Claim
27 words
A friction clutch according to claim 1, characterised in that the said first friction disc includes a said support plate mounted on the circumferentially acting resilient means.
Claim 5
Dependent Claim
19 words
A friction clutch according to claim 3, characterised in that the said openings in the support plate are oblong.
Claim 6
Dependent Claim
21 words
A friction clutch according to claim 4, characterised in that the spacer means extend with a clearance through the oblong openings.
Claim 7
Dependent Claim
34 words
A friction clutch according to claim 5, characterised in that the support plate is centred by means of a bearing which is fixed with respect to the damper plate of the said second part.
