Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
120 words
A segmented brake disk, comprising a plurality of segments, at least a portion of said segments having a tongue, at least a portion of said segments having a recess, said tongue having tapered arcual surfaces and a radial surface, said recess having tapered arcual surfaces and a radial surface, said tongue tapered arcual surfaces and said recess tapered arcual surfaces matingly engaging each other, said segments contacting each other only through said tapered arcual surfaces, said contact of said tapered arcual surfaces being along a minor fractional portion thereof; and said tongue and recess arcual surfaces so engaging each other to form a radial expansion gap between said radial surfaces of said tongue and said recess under all braking conditions.
Claim 2
Dependent Claim
120 words
A segmented brake disk, comprising a plurality of segments, at least a portion of said segments having a tongue, at least a portion of said segments having a recess, said tongue having tapered arcual surfaces and a radial surface, said recess having tapered arcual surfaces and a radial surface, said tongue tapered arcual surfaces and said recess tapered arcual surfaces matingly engaging each other, said segments contacting each other only through said tapered arcual surfaces, said contact of said tapered arcual surfaces being along a minor fractional portion thereof; and said tongue and recess arcual surfaces so engaging each other to form a radial expansion gap between said radial surfaces of said tongue and said recess under all braking conditions.
Claim 3
Dependent Claim
31 words
A segmented brake disk according to claim 1, wherein said tongue is located at one end of said segment and said recess is located on the other end of said segment.
Claim 4
Dependent Claim
15 words
A segmented brake disk according to claim 1, wherein said segments are joined by clips.
Claim 5
Dependent Claim
16 words
A segmented brake disk according to claim 1, wherein said segments are joined by a spring.
Claim 6
Dependent Claim
20 words
A segmented brake disk according to claim 4, wherein each segment is joined to an adjacent segment having a clip.
Claim 7
Dependent Claim
15 words
A segmented brake disk according to claim 1 wherein said segments are of equal length.
Claim 8
Dependent Claim
33 words
A segmented brake disk according to claim 1 wherein said radial expansion gap exists between said segments in addition to said radial gap between said radial surfaces of said tongue and said recess.
Claim 9
Dependent Claim
26 words
A segmented brake disk according to claim 1, wherein said tapered arcual tongue surfaces are tapered inwardly and said tapered arcual recess surfaces are tapered outwardly.
