CONFIGURATION FOR A DISK BRAKE TORQUE TUBE ASSEMBLY HAVING REPLACEABLE KEYS AND BACKPLATE

摘要

A unique configuration for a torque tube assembly associated with a disk type brake comprises separable and replaceable keys and a separable and replaceable brake disk backplate. The keys are mounted in anti-rotation slots at the inboard and outboard ends of the torque tube and bolted to the barrel portion of the torque tube and are characterized by a radial extension that supports the separable backplate. The torque tube is a formed wrought metal tube that is mounted to the stationary portion of the brake housing via bolts that thread into the inboard end of the keys. In this configuration, the occurrence of a defective key and/or backplate does not require replacement of the total torque tube assembly.
