Abstract
Abstract A brakeshoe adapted to limit noise generated by a disc brake wherein an intermediate plate, interposed between the backing plate of the brakeshoe and the piston, is affixed to the backing plate and provides force transmission between the piston and the backing plate which is offcenter from the centrum of the discengaging surface of the brake lining, the force-transmitting portion consisting at least in part of a thermal insulator.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
121 words
A disc brake including a noise-limiting brakeshoe, a rotating brake disc engageably by a face of said brakeshoe, and a piston shiftable perpendicularly to said face to urge said brakeshoe against said disc; said brakeshoe comprising a rigid backing plate extendinG generally parallel to said face, a brake lining secured to said backing plate and forming said face, and two further plates rigidly secured to the other side of said backing plate for engagement by said piston, said further plates contacting each other along a surface parallel to said face, one of said further plates having a recess at said surface and being provided with a layer of thermally insulating material in said recess substantially coextensive in area with said lining.
Claim 2
Dependent Claim
121 words
A disc brake including a noise-limiting brakeshoe, a rotating brake disc engageably by a face of said brakeshoe, and a piston shiftable perpendicularly to said face to urge said brakeshoe against said disc; said brakeshoe comprising a rigid backing plate extendinG generally parallel to said face, a brake lining secured to said backing plate and forming said face, and two further plates rigidly secured to the other side of said backing plate for engagement by said piston, said further plates contacting each other along a surface parallel to said face, one of said further plates having a recess at said surface and being provided with a layer of thermally insulating material in said recess substantially coextensive in area with said lining.
Claim 3
Dependent Claim
15 words
A disc brake as defined in claim 1 wherein said layer consists of synthetic resin.
Claim 4
Dependent Claim
86 words
A disc brake including a noise-limiting brakeshoe, a rotating brake disc; engageable by a face of said brakeshoe, and a piston shiftable perpendicularly to said face to urge said brakeshoe against said disc; said brakeshoe comprising a rigid metal backing plate extending generally parallel to said face and a brake lining secured to said backing plate along one side thereof while forming said face, said backing plate having a planar other side of an area exceeding that of said lining; and an intermediate plate substantially coextensive.
Claim 5
Dependent Claim
86 words
A disc brake including a noise-limiting brakeshoe, a rotating brake disc; engageable by a face of said brakeshoe, and a piston shiftable perpendicularly to said face to urge said brakeshoe against said disc; said brakeshoe comprising a rigid metal backing plate extending generally parallel to said face and a brake lining secured to said backing plate along one side thereof while forming said face, said backing plate having a planar other side of an area exceeding that of said lining; and an intermediate plate substantially coextensive.
Claim 6
Dependent Claim
19 words
The brakeshoe as defined in claim 3 further comprising a layer of thermally insulating material received in said recess.
Claim 7
Dependent Claim
17 words
The brakeshoe as defined in claim 4 wherein said layer is a plate of a synthetic resin.
Claim 8
Dependent Claim
20 words
The brakeshoe as defined in claim 4 wherein said layer is sandwiched between said intermediate plate and said backing plate.
Claim 9
Dependent Claim
13 words
The brakeshoe as defined in claim 4 wherein said step has arc-segmental configuration.
Claim 10
Dependent Claim
26 words
the brakeshoe as defined in claim 4 wherein said step has a flank lying at an angle to a median plane of said plates perpendicular thereto.
