Abstract
Abstract Clutch disc includes a hub, an entrainer plate coaxially disposed and turnable relative to the hub, a pair of clutch friction linings mounted coaxially to one another and to the hub, a damping device located in a force transmission path between the entrainer plate and the hub, on the one hand, and between the pair of clutch friction linings, on the other hand, the damping device comprising force storing means operatively connected to the hub and to the entrainer plate, damping lining means disposed coaxially to the hub, a spring member in stressing engagement with the damping lining means so as to frictionally connect the same to the entrainer plate, the spring member being located in a space between the relatively turnable entrainer plate and the hub and being in the form of a disc abutting the damping lining means at one side thereof and the entrainer plate at the other side thereof, the pair of clutch friction linings being carried by the spring member.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
242 words
Clutch disc comprising a hub, an entrainer plate coaxially disposed and turnable relative to said hub, a pair of clutch friction linings mounted coaxiaLly to one another and to said hub, a damping device located in a force transmission path between said entrainer plate and said hub, on the on hand, and between said pair of clutch friction linings, on the other hand, said damping device comprising force storing means operatively connected to said hub and to said entrainer plate, damping lining means disposed coaxially to said hub, a spring member in stressing engagement with said damping lining means so as to frictionally connect the same to said entrainer plate, said spring member being located in a space between said relatively turnable entrainer plate and a radially extending portion of said hub and being in the form of a disc having a diametrically inner portion thereof abutting said damping lining means at one side thereof and said entrainer plate at the other side thereof, said diametrically inner portion standing away on one side of said spring disc in direction toward said damping lining means, said spring disc having a diametrically outer portion thereof extending diametrically beyond said damping lining means, said spring disc and said entrainer plate being mutually connected at said diametrically outer portion of said spring disc so as to be fixed against rotation relative to one another, said pair of clutch friction linings being carried by said spring member.
Claim 2
Dependent Claim
242 words
Clutch disc comprising a hub, an entrainer plate coaxially disposed and turnable relative to said hub, a pair of clutch friction linings mounted coaxiaLly to one another and to said hub, a damping device located in a force transmission path between said entrainer plate and said hub, on the on hand, and between said pair of clutch friction linings, on the other hand, said damping device comprising force storing means operatively connected to said hub and to said entrainer plate, damping lining means disposed coaxially to said hub, a spring member in stressing engagement with said damping lining means so as to frictionally connect the same to said entrainer plate, said spring member being located in a space between said relatively turnable entrainer plate and a radially extending portion of said hub and being in the form of a disc having a diametrically inner portion thereof abutting said damping lining means at one side thereof and said entrainer plate at the other side thereof, said diametrically inner portion standing away on one side of said spring disc in direction toward said damping lining means, said spring disc having a diametrically outer portion thereof extending diametrically beyond said damping lining means, said spring disc and said entrainer plate being mutually connected at said diametrically outer portion of said spring disc so as to be fixed against rotation relative to one another, said pair of clutch friction linings being carried by said spring member.
Claim 3
Dependent Claim
26 words
Clutch disc according to claim 1, wherein said portion of said spring disc standing away from said plate extends radially outwardly over said damping lining means.
Claim 4
Dependent Claim
24 words
Clutch disc according to claim 1, wherein said spring disc is formed at least in said inner portion thereof with substantially radially directed slots.
Claim 5
Dependent Claim
28 words
Clutch disc according to claim 1 wherein said spring disc, in addition to carrying said clutch friction linings, serving simultaneously for applying force to said damping lining means.
Claim 6
Dependent Claim
33 words
Clutch disc according to claim 1, wherein said spring disc is subdivided in the region thereof adjacent said clutch friction linings, into individual wave-shaped segments extending in peripheral direction of the clutch disc.
Claim 7
Dependent Claim
63 words
Clutch disc according to claim 5, including, in the region of said clutch friction linings, individual spring segments having a wave-like shape in peripheral direction of the clutch disc abut said spring disc, and spacer rivets with a step-shaped profile prestressing both said friction linings, said spacer rivets securing said friction linings respectively alternatingly to said spring member and to said wave-shaped segments.
Claim 8
Dependent Claim
222 words
Clutch disc comprising a hub, an entrainer plate coaxially disposed and turnable relative to said hub, a pair of clutch friction linings mounted coaxially to one another and to said hub, a damping device located in a force transmission path between said entrainer plate and said hub, on the one hand, and between said pair of clutch friction linings, on the other hand, said damping device comprising force storing means operatively connected to said hub and to said entrainer plate, damping lining means disposed coaxially to said hub, a spring member in stressing engagement with said damping lining means so as to frictionally connect the same to said entrainer plate, said spring member being located in a space between said relatively turnable entrainer plate and a radially extending portion of said hub and being in the form of a disc abutting said damping lining means at one side thereof and said entrainer plate at the other side thereof, said spring disc and said entrainer plate being mutually connected so as to be nonrotatable relative to one another, said pair of clutch friction linings being carried by said spring member, and a cover disc coaxially mounted on said hub, said spring disc and said entrainer plate being secured to one another by spacer rivets that connect said entrainer plate to said cover disc.
Claim 9
Dependent Claim
222 words
Clutch disc comprising a hub, an entrainer plate coaxially disposed and turnable relative to said hub, a pair of clutch friction linings mounted coaxially to one another and to said hub, a damping device located in a force transmission path between said entrainer plate and said hub, on the one hand, and between said pair of clutch friction linings, on the other hand, said damping device comprising force storing means operatively connected to said hub and to said entrainer plate, damping lining means disposed coaxially to said hub, a spring member in stressing engagement with said damping lining means so as to frictionally connect the same to said entrainer plate, said spring member being located in a space between said relatively turnable entrainer plate and a radially extending portion of said hub and being in the form of a disc abutting said damping lining means at one side thereof and said entrainer plate at the other side thereof, said spring disc and said entrainer plate being mutually connected so as to be nonrotatable relative to one another, said pair of clutch friction linings being carried by said spring member, and a cover disc coaxially mounted on said hub, said spring disc and said entrainer plate being secured to one another by spacer rivets that connect said entrainer plate to said cover disc.
