Abstract
A torque tube and conical back plate for aircraft brakes including a torque tube having a truncated back plate of thin metal construction extending from the outboard end thereof. The conical back plate is characterized by inner and outer reinforcing rings, such rings providing a compressive force at opposite ends of the truncated cone of the back plate, thus allowing the back plate to resist bending and deflection. In accordance with the invention, the cross sectional centers of mass of the inner and outer reinforcing rings are shifted outboard from a projection of the center plane of the conical back plate, such positioning enhancing the stiffening and reinforcing capabilities of the reinforcing rings.
Claims3
A torque tube and conical back plate assembly for aircraft brakes, comprising:
- a torque tube for receiving stator disks of a brake disk stack, said torque tube having an inboard end and an outboard end with respect to an orientation of mounting on an aircraft;
- a conical back plate extending from the outboard end of said torque tube, said conical back plate being of increasing diameter as it extends from said outboard end;
- first and second reinforcing rings circumferentially encompassing opposite ends of said conical back plate;
- and
- wherein a center of mass of each of said first and second reinforcing rings lies outboard of a center plane projection of said conical back plate.
