Total Claims: 8
Claim 1
Independent Claim
229 words
A brake disc assembly comprising: a hub provided with circumferential radial flange means extending therefrom and having front and rear annular faces; at least two sector-shaped lining parts which together form an annular assembly, each part being of monolithic construction and including confronting front and rear sector-shaped linings, all of said sector-shaped linings forming together front and rear annular linings the outer surfaces of which will be acted on by braking jaws during use of the assembly, each of said parts being removably fitted over said flange means in concentric relationship with said hub so that said flange means lies between the opposed surfaces of the confronting front and rear sector-shaped linings, said linings having radially extending inner ribs projecting therefrom so as to form cooling passages open at both their radial inner and outer ends, at least some of said ribs having edges which serve as guides for said sector-shaped lining parts during fitting of the latter over said flange in a radial direction and during operation when thermal expansion occurs, said rib edges engaging said flange means in the completed brake disc assembly; and for each sector-shaped lining part a single removable connecting element extending parallel to the axis of said hub and connecting the respective lining part with said flange, each of said connecting elements being located approximately at the center of the respective lining part.
Claim 2
Dependent Claim
229 words
A brake disc assembly comprising: a hub provided with circumferential radial flange means extending therefrom and having front and rear annular faces; at least two sector-shaped lining parts which together form an annular assembly, each part being of monolithic construction and including confronting front and rear sector-shaped linings, all of said sector-shaped linings forming together front and rear annular linings the outer surfaces of which will be acted on by braking jaws during use of the assembly, each of said parts being removably fitted over said flange means in concentric relationship with said hub so that said flange means lies between the opposed surfaces of the confronting front and rear sector-shaped linings, said linings having radially extending inner ribs projecting therefrom so as to form cooling passages open at both their radial inner and outer ends, at least some of said ribs having edges which serve as guides for said sector-shaped lining parts during fitting of the latter over said flange in a radial direction and during operation when thermal expansion occurs, said rib edges engaging said flange means in the completed brake disc assembly; and for each sector-shaped lining part a single removable connecting element extending parallel to the axis of said hub and connecting the respective lining part with said flange, each of said connecting elements being located approximately at the center of the respective lining part.
Claim 3
Dependent Claim
61 words
A brake disc assembly as in claim 1 wherein each of said connecting elements is located in a hole passing through the respective sector shaped lining part and through an aligned hole in said flange means, the hole in said lining part passing through two of said inner radial ribs, said two ribs having enlarged cross-sections which accommodate the holes therein.
Claim 4
Dependent Claim
29 words
A brake disc assembly as in claim 1 wherein said connecting element is located in an area on which brake jaws act during use of the brake disc assembly.
Claim 5
Dependent Claim
60 words
A brake disc assembly as in claim 1 including at least one pin for aiding in maintaining the sector shaped lining parts concentric with said hub, said pin lying in a plane parallel to the plane of said flange means and having two opposite end portions each of which is fitted in a hole in one of said lining parts.
Claim 6
Dependent Claim
32 words
A brake disc assembly as in claim 1 wherein at least some of said ribs have edges which engage the edges of opposed ribs at locations radially outward of said flange means.
Claim 7
Dependent Claim
31 words
A brake disc assembly as in claim 1 wherein the confronting front and rear linings of each sector-shaped part are welded together at their outer edges to form said monolithic construction.
Claim 8
Dependent Claim
30 words
A brake disc assembly as in claim 1 wherein the confronting front and rear linings of each sector-shaped part are cast as a single part to form said monolithic construction.
