Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
102 words
An antirattling device for a spot-type disc brake in which two brake pads are slidably supported on a pair of pins secured to a hydraulic cylinder disposed on one side of a brake disc, said hydraulic cylinder having two opposed pistons for actuating the brake pads, one of said brake pads being actuated by means of a substantially annular transfer member actuated by one of the opposed pistons, said device comprising a metal plate having resilient means for engaging one face and inside opposed edges of the substantially annular transfer member and having resilient means engaging the pins supporting the brake pads.
Claim 2
Dependent Claim
102 words
An antirattling device for a spot-type disc brake in which two brake pads are slidably supported on a pair of pins secured to a hydraulic cylinder disposed on one side of a brake disc, said hydraulic cylinder having two opposed pistons for actuating the brake pads, one of said brake pads being actuated by means of a substantially annular transfer member actuated by one of the opposed pistons, said device comprising a metal plate having resilient means for engaging one face and inside opposed edges of the substantially annular transfer member and having resilient means engaging the pins supporting the brake pads.
Claim 3
Dependent Claim
29 words
A device as claimed in claim 1 wherein said metal plate has a central portion for shielding the brake pads to prevent access of foreign material thereto during use.
Claim 4
Dependent Claim
20 words
A device as claimed in claim 1 wherein said metal plate is formed from a rectangular metal sheet by stamping.
Claim 5
Dependent Claim
48 words
A device as claimed in claim 1 wherein each end of said metal plate is provided with a pair of resilient means for engaging the upper face of the substantially annular transfer member and a resilient means for engaging an inside edge of the substantially annular transfer member.
Claim 6
Dependent Claim
48 words
A device as claimed in claim 1 wherein each end of the metal plate is provided with a resilient means for engaging an upper face of the substantially annular transfer member and a pair of resilient means for engaging an inside edge of the substantially annular transfer member.
Claim 7
Dependent Claim
45 words
A device as claimed in claim 1 wherein each end of the metal plate is provided with a resilient means for engaging a face of the substantially annular transfer member and a resilient means for engaging an inside edge of the substantially annular transfer member.
