In some examples, an assembly includes a rotor drive key configured to fit around a wheel boss defined by a wheel of a vehicle. The rotor drive key includes a support member. The assembly further comprises a fastener configured to extend through the wheel boss and the support member in a substantially axial direction of the wheel when the rotor drive key is fit around the wheel boss. A fastening member is configured to engage with a portion of the fastener extending beyond the support member.

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.

A torque tube for a brake assembly may include a tube portion having a first centerline axis, a conical back-leg portion extending from the tube portion in a radially outward angled orientation relative to the first centerline axis, and a lip portion disposed at a radially outward end of the conical back-leg portion. The lip portion may have added structural material to improve the structural properties of the torque tube to prevent or mitigate damage that would otherwise be caused by friction-induced vibrations.

A brake actuator assembly may comprise a housing, a piston disposed in the housing and slidably engaged therewith, a resilient member disposed within the housing and coupled to the piston, and a deformable member disposed within the housing a coupled to the piston, wherein each of the deformable member and the resilient member are disposed radially between a piston rod of the piston and the housing.

A brake wear sensor is disclosed. In various embodiments, the brake wear sensor includes a bias member configured for connection between a stationary portion of a brake mechanism and a heat sink; and a load cell configured to measure a load in the bias member representative of a length of the heat sink.

The invention relates to a braking and/or clamping device for a shaft guided in relation to a main body, comprising an actuation assembly and a shaft-coupling assembly. In this case, the actuation assembly comprises a split housing which has two bending plates which are elastically deformable in some regions. The bending plates each have tong jaws with friction surfaces, the respective surface normal of which are directed inwards. A sealed pressure chamber, which can be filled with a pressure medium, lies between the bending plates. Parts of a shaft-coupling assembly project between the clamping zones, said parts establishing the linking for the braked or clamped shaft. When the pressure in the pressure chamber is relieved, the frictional surfaces of the actuation assembly can be applied to the frictional surfaces of the shaft-coupling assembly, thereby producing the braking and/or clamping force. According to the present invention, a braking and/or clamping device is developed, which has a reduced structural width even with a large diameter, consists of few components and also functions in a simple, secure and maintenance-free manner.

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 system, and associated method, for reducing oxidation of a friction disk may include a braking assembly comprising the friction disk and a coolant loop coupled to the braking assembly, with the coolant loop being configured to circulate liquid coolant from the braking assembly. That is, the coolant loop may be configured to reduce the temperature of the braking assembly, thus reducing the rate/extent of oxidation of the friction disks and potentially enabling the concentration of oxygen around the braking assembly to be reduced.

A friction disk includes a friction disk core having an inner diameter edge, an outer diameter edge, and a first surface with multiple mortises extending radially across the first surface, each of the multiple mortises having a different dimension at the inner diameter edge than at the outer diameter edge. The friction disk further includes a first wear liner having two wear liner segments each including a wear surface and a non-wear surface having a tenon with a complimentary shape to each of the multiple mortises, the tenon being configured to be received by a corresponding mortise of the multiple mortises to couple the wear liner segments to the friction disk core to form an annular liner.
