A torque bar assembly for use in an aircraft wheel is disclosed. In various embodiments, the assembly includes a torque bar; and a spacer configured for positioning between the torque bar and a wheel well of the aircraft wheel and to thermally insulate the wheel well from the torque bar, wherein the spacer includes a first anodized metal oxide layer on a first surface of the spacer configured to contact the torque bar. In various embodiments, the spacer includes a second anodized metal oxide layer on a second surface of the spacer configured to contact the wheel well.

In some examples, an assembly includes a rotor drive key configured to fit around a wheel boss defined by a wheel. The rotor drive key includes a support structure. The assembly further includes a fastener configured to extend the wheel boss and the support structure in a substantially axial direction of the wheel when the rotor drive key fits around the wheel boss, where the fastener is configured to limit movement of the rotor drive key relative to the wheel boss. The fastener may be rotated to establish and/or increase a contact pressure between the fastener and the rotor drive key to help the fastener limit movement of the rotor drive key relative to the wheel boss.

An aircraft braked wheel comprising a rim integral with a hub for rotationally mounting thereof on an axle of the aircraft along an axis of rotation, the wheel being equipped with a heat shield (11) extending opposite an inner face of the rim to protect the rim from the thermal radiation generated by a stack of discs extending inside the rim, characterized in that the heat shield has a face facing the discs (15) which has longitudinal ribs (16) extending in operation parallel to the axis of rotation of the wheel.

A chin ring heat shield for a wheel assembly arranged to provide a shield between convection and radiation heat from braking components and a tire of the wheel assembly, the chin ring comprising a first, radially extending, flat portion extending from a first chin ring end and a second, concave portion extending generally axially away from the first portion to a second chin ring end, wherein the axial length from the first chin ring end to the second chin ring end is sufficient to block a line of sight between the braking components and the tire when the chin ring is mounted between the braking components and the tire.

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.

A brake system comprising a brake disc, a wheel hub connected to the brake disc, and a bearing assembly mounted around the wheel hub, the brake system further comprising: a first electric circuit embedded inside the brake disc; a second electric circuit embedded inside the wheel hub and electrically connected with the first electric circuit; and a third electric circuit embedded inside the bearing assembly and electrically connected with the second electric circuit, wherein when an electric current flows to the first electric circuit through the second and third electric circuits, the first electric circuit generates heat for applying to the brake disc.

A brake drum includes an outer drum, at least one layer of heat resistant adhesive, provided at least on the inner radial surface of the outer drum, and an inner drum provided inside the outer drum connected with the outer drum via the at least one adhesive layer.

A rotor drive bar for use in a brake system, according to various embodiments, includes a drive bar portion configured to be coupled to at least one rotor of the brake system. The rotor drive bar also includes an attachment boss configured to be coupled to an attachment platform of a wheel. The attachment boss has a boss face that faces the attachment platform and at least partially defines a pocket for reducing thermal transfer from the rotor drive bar to the wheel.

A heat shield assembly for a wheel is disclosed. The heat shield assembly includes a heat shield having a pair of heat shield ends. A bifurcated seam mounting bracket includes a first bracket section that is fixed relative one of the heat shield ends, along with a second bracket section that is fixed relative to the other of the heat shield ends. The second bracket section may be directly mounted to the heat shield. A seam clasp section may be directly mounted to both the heat shield and the first bracket section such that the first bracket section is indirectly mounted to the heat shield.

A heat shield for a wheel is disclosed. A torque bar may be used to mount the heat shield to the wheel, and includes a connector in the form of a stem and a head. A stiffening or reinforcement plate is mounted to the heat shield with a torque bar mounting aperture extending through the reinforcement plate being disposed about at least part of a torque bar mounting aperture extending through the heat shield. The torque bar mounting aperture of the reinforcement plate is disposed/configured such that the head of the torque bar may be disposed in overlying relation to portions of an outer surface of the heat shield that are on opposite sides of the torque bar mounting aperture through the heat shield that are exposed by the torque bar mounting aperture through the reinforcement plate.
