Abstract
A friction device such as an aircraft wheel and brake assembly having a wheel member journaled for rotation on a fixed member, which fixed member supports a torque tube member. A plurality of primary friction disks are carried by splines on the wheel member while a plurality of secondary friction disks are carried by splines on the torque tube member with such secondary disks interleaved with the primary friction disks for axial movement towards one end of the torque tube. An actuator, such as a plurality of pistons, is mounted on the fixed member to urge all the friction disks into frictional engagement with each other and against a stationary disk on the one end of the torque tube. A rigid disk is positioned between the actuator and the pluralities of friction disks, and acts as a pressure plate. The rigid disk may be formed of carbon or ceramic composite material.
