A method of making a brake assembly using recycled friction disks may comprise removing a first friction disk from a worn brake assembly, removing a portion of the first friction disk to reduce a thickness of the first friction disk, and incorporating a previously unused friction disk and the first friction disk into a brake assembly comprising unworn rotor disks made of a first material. The previously unused friction disk and the first friction disk may comprise a second material different from the first material. The thickness of the first friction disk may be different from a thickness of the previously unused friction disk.

A connect and disconnect assembly may have a first rotatable shaft and a second rotatable shaft aligned along a rotational axis. The assembly may also have a connect and disconnect device including one or more cams for selectively connecting and disconnecting the first rotatable shaft to and from the second rotatable shaft. A ship-lift bogie may include the connect and disconnect assembly.

An actuation mechanism for a multi-plate disc brake includes an energy storage element configured to apply said disc brake, the energy storage element being movable between a first position where said disc brake is released, and a second position where said disc brake is applied; a force transmission path configured to transmit force from the energy storage element to apply said disc brake; and a hydraulic chamber. The force transmission path includes a first member and a second member arranged in series; wherein the hydraulic chamber is configured, when pressurized, to act on the first member such that the energy storage element is moved to the first position; and wherein the second member is separated from the chamber such that, when the chamber is pressurized, no pressure is applied to the second member.

An electric drive module that includes a housing, a pair of drive units and a coupling unit. The drive units are disposed in the housing and each drive unit includes a motor unit and a friction brake. The motor unit has a stator, which is non-rotatably coupled to the housing, and a rotor that is rotatable about a motor axis and configured to drive a wheel of a vehicle. The friction brake has a first portion, which is non-rotatably coupled to the housing, and a second portion that is drivingly coupled to the rotor. The friction brake can be operated to create a rotational drag force that resists rotation of the second portion relative to the first portion. The coupling unit is configured to selectively rotatably couple the second portions of the friction brakes to one another.

An aircraft landing gear arrangement may comprise a landing gear bogie having an axle, a torque tube surrounding the axle and mechanically coupled to the landing gear bogie. A brake stack may surround the torque tube. The torque tube may comprise a cylindrical body extending between a first end and a second end. A flange may be disposed at the first end. A mating surface may be disposed on the first end or the second end of the torque tube for mating the torque tube to the landing gear bogie. A bogie flange may extend from the landing gear bogie whereby the torque tube may be mounted to the landing gear bogie.

A multi-disk brake assembly includes a static structure defining a plurality of slots, a plurality of disks including stator disks that are supported by the static structure and are non-rotatable, and rotor disks that are interleaved with the stator disks and are rotatable, the plurality of disks being axially moveable between an engaged position and a disengaged position, and a dust-collecting receptacle that is attachable to the static structure for securement during an operative state of the multi-disk brake assembly. The dust-collecting receptacle is in fluid communication with the plurality of slots for receiving and trapping dust from the plurality of disks through the plurality of slots. The dust-collecting receptacle is detachable relative to the static structure during a non-operative state of the multi-disk brake assembly.

An article includes a structural core, one or more friction pads, and a plurality of elongated fasteners. The structural core includes two core surfaces and a plurality of pockets extending between the core surfaces. Each friction pad includes a pad surface and a friction surface opposite the pad surface. Each pad surface includes a planar pad surface configured to contact the core surface and a plurality of bosses extending from the first planar pad surface and including a bore. Each planar pad surface is at least about 50% of a surface area of the respective first and second pad surfaces. The plurality of bosses engages with the plurality of pockets to position the respective first and second friction pads relative to the structural core. The plurality of elongated fasteners passes through bores of corresponding bosses of friction pads to fasten the friction pads to the structural core.
