Patent ID: 8657080

Claim:
An annular disk brake having a central axis, the brake comprising: a main support coaxially disposed with reference to the central axis; a rotor disk coaxially disposed with reference to the central axis and being in a sliding and torque-transmitting engagement with the main support, the rotor disk having opposite outboard and inboard sides; a casing inside which the main support is mounted for rotation around the central axis; at least one first brake pad having a surface facing the outboard side of the rotor disk, the at least one first brake pad being connected inside the casing; at least one second brake pad having a surface facing the inboard side of the rotor disk; a substantially axially-guided brake pad carrier coaxially disposed with reference to the central axis, the brake pad carrier having opposite outboard and inboard sides, the at least one second brake pad being positioned on the outboard side of the brake pad carrier; an actuator assembly connected to the casing, the actuator assembly comprising an axially-actuated member; and a force transmitting arrangement comprising a first cam interface between the axially-actuated member and an intermediary member located between the axially-actuated member and the inboard side of the brake pad carrier, the intermediary member being coaxially disposed with reference to the central axis and pivoting in a radial plane, the arrangement further comprising a second cam interface between the intermediary member and the inboard side of the brake pad carrier, the brake pad carrier axially moving when the intermediary member pivots, whereby the arrangement creates a force increasing amplification between the axially-actuated member and the inboard side of the brake pad carrier.
