Abstract
In the case of a friction lining, intended in particular for brake systems and comprising a friction element consisting of asbestos-free friction lining material and an abrasive element consisting of abrasive material with a thermosetting binder on the basis of natural or synthetic resin, it is provided that an abrasive element is incorporated in the friction element which, as wear of the friction lining advances, enables the frictional properties of the surface which presses against the lining to be regenerated at intervals.
Claims11
A friction lining for refurbishing a frictional surface of a braking means comprising a layer shaped friction element comprising an asbestos-free friction lining material and a layer shaped abrasive element comprising abrasive material with a thermo-setting binding agent of natural or synthetic resin, characterized in that said abrasive element (6) is arranged, as an intermediate layer, between successive friction element layers (4) whereby upon the wearing away of a friction layer element (4), a successive abrasive element (6) is exposed for abrading away and smoothing said frictional surface thereby maintaining said surface in an optimum state.
A method of manufacturing friction linings by compacting an asbestos-free friction lining material to form friction element layers, characterized by separately manufacturing a layer-shaped abrasive element by extruding, pressing or punching and by subsequently compacting the layer-shaped abrasive element, as an intermediate layer, together with several friction element layers whereby in use the wearing away of a friction element layer exposes a successive abrasive element for abrading away and smoothing an associated frictional surface thereby maintaining said surface in an optimum state.
