Abstract
An anti-noise shim (100) comprising at least a perforated metal layer (110) and at least a high temperature resistant layer (120) faced/coupled together by mechanical bonding wherein the perforated metal layer comprises through holes (111) and mechanical bonding means (112), and the high temperature resistant layer comprises fibers, a filler and a binder.
Claims18
Anti-noise shim comprising at least a perforated metal layer and at least a high temperature resistant layer faced/coupled together by mechanical bonding wherein the perforated metal layer comprises through holes and mechanical bonding means, and the high temperature resistant layer comprises fibers, a filler and a binder material, said perforated metal layer is characterized by leaving voids in the metal due to the through holes and sharped/pointed mechanical bonding means jointly/united with the perforated metal layer and, where present, located at the edge of the through holes on at least a mechanically bonding surface of the perforated metal layer.
Method of producing anti-noise shim comprising the steps:
- providing a perforated metal sheet comprising through holes and mechanical bonding means, said perforated metal sheet is characterized by leaving voids in the metal due to the through holes and sharped/pointed mechanical bonding means jointly/united with the perforated metal sheet and, where present, located at the edge of the through holes on at least a mechanically bonding surface of the perforated metal sheet, and
- mechanically bonding, by applying pressure or pressure and temperature, a high temperature resistant sheet comprising fibres, a filler and a binder on at least one side of the perforated metal sheet to form an anti-noise shims sheet.
Disc brake arrangement comprising:
- a caliper,
- a brake pad, and
- an anti-noise brake shim comprising at least a perforated metal layer and at least a high temperature resistant layer faced/coupled together by mechanical bonding wherein the perforated metal layer comprises through holes and mechanical bonding means, and the high temperature resistant layer comprises fibers, a filler and a binder material, said perforated metal layer is characterized by leaving voids in the metal due to the through holes and sharped/pointed mechanical bonding means jointly/united with the perforated metal layer and, where present, located at the edge of the through holes on at least a mechanically bonding surface of the perforated metal layer,
- wherein the anti-noise brake shim is disposed between the caliper and the brake pad.
