A load-taking device for use in the disc pack of a multi-disc brake assembly. The load-taking device is located at one end of the pack, interposed between the pack and a cylinder for applying thrust to the pack or for resisting thrust applied to the pack. It has an annular support and a plurality of hollow bell-shaped load-taking members extending from one side of the support in circumferentially spaced relation which are rounded at the ends which contact the adjacent disc of the pack.

Load-taking apparatus for a disc pack

An annular friction element for a multi-disc brake comprises pads of friction material alternating around the element with radial arms by which the pads are clamped relative to a ring joining the arms, the arms being of greater extent than the ring radially of the element.

Multi-disc brakes

In an aircraft wheel and disc brake assembly wherein carbon rotor discs keyed to the wheel are interleaved with carbon stator discs keyed to a torque tube fixed to the axle and in which a fixed draught of air is passed through and around the disc pack, the consequential increase in oxidation of the carbon discs is obviated or minimized by the employment of heat shield members between the keys of the torque tube and the wheel rim which define passages for the flow of cooling air isolated from the disc pack. The keys of the torque tube may be hollow and may be formed with apertures whereby the interior communicates with the passages so that cooling air also passes through the interior of the torque tube keys.

Air cooled disc brake

A disc brake comprising a number of interleaved rotor and stator elements and a brake actuator which is arranged to urge the rotor and stator elements into engagement in order to apply the brake. The engagement surfaces of the rotors and stators are provided with areas of carbon and non-carbon based friction material which are arranged so that the disc brake consists of a number of iron friction pairs and a number of carbon friction pairs, the iron friction pairs being located nearer to an open end of the brake structure so that the friction pairs most likely to be wet are those which perform best when wet.
