Torsion damping assembly especially for a friction clutch plate assembly

Claim 2

A friction clutch plate assembly comprising a hub, a web extending radially outwardly from said hub, two identical annular guiding plates, one said annular guiding plate on each side of said web, cross members interconnecting said annular plates, said annular plates being mounted for predetermined angular displacement relative to said web of said hub, a friction disc secured to a first of said annular plates through a plurality of passages at the outer periphery thereof and carrying friction linings at its periphery, a circumferential array of resilient means interposed between said web and said annular plates, and friction shoe means disposed between said web and the other of said annular plates being operative over at least a portion of the limited relative angular displacement thereof, means for securing said friction shoe means through passages in said other annular plate which are identical with said plurality of passages in said first annular plate.

Claim 3

An assembly according to claim 1, wherein said means for securing said friction shoe means through said passage in said second annular plate comprises dowels on one side of a support plate for said friction shoe means, said dowels being shaped and arranged to engage said passages in said second annular plate, friction lining being provided on the other side of said support plate for said friction shoe means.

Claim 4

An assembly according to claim 1, wherein said friction lining is secured directly to said other annular plate through said passages therein.

Claim 5

An assembly according to claim 3, wherein said means for securing said friction shoe means to said other annular plate comprises rivets.

Claim 6

An assembly according to claim 1, wherein said friction shoe means has a notch for passage of one of said cross member therethrough.

Claim 7

An assembly according to claim 1, wherein there are a plurality of said friction shoes disposed in an annular arrangement.

Claim 8

An assembly according to claim 6, wherein said friction shoes are disposed in a continuous annular arrangement.

Claim 9

A friction clutch plate assembly comprising a hub, a web extending radially outwardly from said hub, two identical annular guiding plates, one of said annular plates being disposed on each side of said web, cross members interconnecting said annular plates, means mounting said annular plates for predetermined angular displacement relative to said web of said hub, a friction disc secured to a first of said annular plates through a plurality of passages at the outer periphery thereof, said friction disc carrying friction lining at its outer periphery, a circumferential array of resilient means interposed between said web and said annular plates, a corresponding plurality of passages in the other of said guide plates in registry with said plurality of passages in said first annular plate for accommodating friction shoes, each friction shoe comprising a mounting member having dowels projecting generally axially from one side thereof, each said dowel being inserted and secured in one of said plurality of passages in said other annular plate, and a friction pad fixed on the other side of said mounting member facing and in frictional engagement with an opposed radial surface of said web, said friction shoes being operative over at least a portion of the limited relative angular displacement of said angular plates.

Claim 10

A friction clutch plate assembly comprising a hub, a web extending radially outwardly from said hub, two identical annular guiding plates, one of said annular plates being disposed on each side of said web, cross members interconnecting said annular plates, means mounting said annular plates for predetermined angular displacement relative to said web of said hub, a friction disc secured to a first of said annular plates through a plurality of passages at the outer periphery thereof, said friction disc carrying friction lining at its outer periphery, a circumferential array of resilient means interposed between said web and said annular plates, a corresponding plurality of passages in the other of said guide plates in registry with said plurality of passages in said first annular plate for accommodating friction shoes, each friction shoe comprising a mounting member having dowels projecting generally axially from one side thereof, each said dowel being inserted and secured in one of said plurality of passages in said other annular plate, and a friction pad fixed on the other side of said mounting member facing and in frictional engagement with an opposed radial surface of said web, said friction shoes being operative over at least a portion of the limited relative angular displacement of said angular plates.

Claim 11

An assembly according to claim 8, wherein said friction pads are of part annular configuration, the radial dimension of said friction pads being substantially equal to that of the corresponding mounting members.

Claim 12

An assembly according to claim 9, wherein there is a depression on the mounting members opposite said dowels, and said friction pads overlying said depression.

Claim 13

An assembly according to claim 9, wherein said dowels are force-fitted in their corresponding passages.

Claim 14

An assembly according to claim 8, wherein said dowels are stamped portions in said mounting members.
