A brake for an aircraft includes a housing, a shaft defining an axis (X) and extending into the housing, a floating brake disk on the shaft, the brake disk fixed for rotation with the shaft and arranged to be axially movable within the housing, a static brake pad arranged on a first side of the floating brake disk, a movable brake pad arranged on a second, opposite, side of the floating brake disk and biasing means for moving the movable brake pad relative to the housing to press the movable brake pad against the floating brake disk. The biasing means press the floating brake disk against the static brake pad to apply braking force to the floating brake disk. The brake also includes a thermal fuse in thermal contact with the static brake pad. The thermal fuse has a fusing temperature, T, above which the thermal fuse fuses.

A brake drum for utility vehicles configured to mount rotatably about an axis of rotation and including a friction section and a connection section, wherein the friction section includes a friction surface and a plurality of transmission structures, wherein the connection section comprises at least one mounting surface and a plurality of transfer structures, wherein the transfer structures engage positively and/or nonpositively in the respective complementary transmission structures so that a torque about the axis of rotation can be transmitted positively, and wherein the mounting surface serves to fix the brake drum indirectly or directly to a hub.

In some examples, a rotor drive key assembly configured to be positioned on a wheel includes an insert and a rotor drive key. The insert is configured to mate with a wheel boss of the wheel and mechanically connect the rotor drive key with the wheel boss. The rotor drive key is configured to mate with the insert such that the insert limits movement of the rotor drive key relative to the wheel boss in at least a radial direction of the wheel. In some examples, the rotor drive key includes a tab having a tab aperture configured to receive a fastener extending in an axial direction of the wheel and engaging the wheel boss.

A brake pad for a motor vehicle is provided. The brake pad includes a body having an upper edge and a lower edge. The upper edge is configured for positioning relative to an outer diameter of a rotor. The brake pad also includes a friction surface extending between the upper edge and the lower edge for engaging the rotor. The brake pad further includes a relieved portion located along a section of the upper edge. The relieved portion is configured to reduce squeal noise caused by tangential modes of the rotor, during engagement of the brake pad with the rotor, by minimizing contact between the friction surface of the brake pad and the outer diameter of the rotor at an area of the rotor having a potential for high modal displacement in a tangential direction.

A self-activated no-back device includes a housing, an input shaft, an output shaft, a reactor hub, first grooves, a brake hub, second grooves, a plurality of balls, a reactor plate, a brake pack, a reactor spring, and a load spring. The first grooves are formed on an interior side of the reactor hub interior side, and the second grooves are formed in an interior side of the brake hub. Each second groove is aligned with a different first groove to define a plurality of groove pairs. Each ball is positioned in a different one of the groove pairs. One side of the reactor plate contacts the reactor hub. The brake pack is selectively contacted by the brake hub. The reactor spring supplies a spring force to the reactor plate, and the load spring supplies a spring force to the brake pack.

In some implementations of the current subject matter, a brake rotor can include a supporting layer applied to a friction surface of a brake rotor substrate, which can optionally include cast iron, and a coating applied over the supporting layer. The supporting layer can include a preparatory metal, and the coating can impart wear and corrosion resistant properties to the friction surface. Related systems, methods, articles of manufacture, and the like are disclosed.

A safety brake system (40; 240) for use in a conveyance system. The safety brake system (40; 240) includes a guide rail (20) and a conveyance component moveable along the guide rail (20). The safety brake system (40; 240) includes a safety brake (42; 242), a linkage mechanism (56; 256) and an actuator (44; 144; 244) for the safety brake (42; 242). The safety brake (42; 242) is moveable between a non-braking position where the safety brake (42; 242) is not in engagement with the guide rail (20) and a braking position where the safety brake (42; 242) is engaged with the guide rail (20). The actuator (44; 144; 244) is configured to be mounted to the conveyance component and positioned between first and second ferromagnetic components. The actuator includes an array of magnetic components including a first magnetic component adjacent to and arranged between two second magnetic components.
