Abstract
Abstract A unique configuration for a torque tube assembly (100) associated with a disk type brake comprises separable and replaceable keys (60) and a separable and replaceable brake disk backplate (70). The keys (60) are mounted in anti-rotation slots (52, 54) at the inboard and outboard ends of the torque tube (50) and bolted to the barrel portion of the torque tube and are characterized by a radial extension (60d) that supports the separable backplate (70). The torque tube (50) is a formed wrought metal tube that is mounted to the stationary portion of the brake housing (14) via bolts (69) that thread into the inboard end (60a) of the keys (60). in this configuration, the occurence of a defective key and/or backplate does not require replacement of the total torque tube assembly.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
211 words
In a brake assembly including a brake housing, an axle, a rotatable member on the axle, and a multi-disk brake stack of alternating rotating and stationary components to provide braking of the rotatable member when subjected to a pressure force on the brake stack, a sub-assembly for stationary mounting with respect to the brake housing to provide torque takeout, keying interconnections, and disk brake backup for the brake, the sub-assembly characterized by: a cylindrically shaped torque tube mounted axially about the axle and having an inboard end as determined by the brake housing and an outboard end as determined by the rotating member, said torque tube having a plurality of spaced-apart slots in the tube about the periphery of each end wherein each slot at the inboard end is axially aligned with a respective slot in the outboard end; and a plurality of bar-shaped keys mounted axially on the torque tube in spanned relationship between one of said inboard and one of said outboard slots and engaged within said slots to provide keying interconnections for the stationary components of the brake stack and each said key having a radial extension at the outboard end to provide backup for the brake stack when said stack is subjected to a braking pressure force.
Claim 2
Dependent Claim
211 words
In a brake assembly including a brake housing, an axle, a rotatable member on the axle, and a multi-disk brake stack of alternating rotating and stationary components to provide braking of the rotatable member when subjected to a pressure force on the brake stack, a sub-assembly for stationary mounting with respect to the brake housing to provide torque takeout, keying interconnections, and disk brake backup for the brake, the sub-assembly characterized by: a cylindrically shaped torque tube mounted axially about the axle and having an inboard end as determined by the brake housing and an outboard end as determined by the rotating member, said torque tube having a plurality of spaced-apart slots in the tube about the periphery of each end wherein each slot at the inboard end is axially aligned with a respective slot in the outboard end; and a plurality of bar-shaped keys mounted axially on the torque tube in spanned relationship between one of said inboard and one of said outboard slots and engaged within said slots to provide keying interconnections for the stationary components of the brake stack and each said key having a radial extension at the outboard end to provide backup for the brake stack when said stack is subjected to a braking pressure force.
Claim 3
Dependent Claim
43 words
The sub-assembly as set forth in Claim 1 characterized by the torque tube being affixed to the brake housing via a plurality of bolts, each said bolt mounted in the brake housing and threadably engaged within the inboard end of a respective key.
Claim 4
Dependent Claim
40 words
The sub-assembly as set forth in either of Claims 1 or 2 characterized by each key being affixed to the torque tube via at least one bolt passing through the tube and threadably engaged within the body of the key.
Claim 5
Dependent Claim
48 words
The sub-assembly as set forth in Claim I further characterized by a backplate disk mounted on the torque tube at the outboard end thereof and abutting the radial extensions of the keys to provide a backpressure plate for the brake stack when subjected to a braking pressure force.
Claim 6
Dependent Claim
25 words
The sub-assembly as set forth in Claim 4 characterized by the backplate disk also being in keying relationship with the keys on the torque tube.
Claim 7
Dependent Claim
32 words
The sub-assembly as set forth in Claim 1 characterized by said torque tube having a radial extension within its bore to provide support to the tube in its mounting on the axle.
Claim 8
Dependent Claim
48 words
The sub-assembly as set forth in Claim 1 characterized by said keys having inboard and outboard extensions in the body of the key which depend into respective inboard and outboard slots, to seat into and engage the slots to provide torque takeout in the application of the brake.
Claim 9
Dependent Claim
50 words
The sub-assembly as set forth in Claim 1 characterized by said tube having a diameter Dl throughout the substantial portion of its length and a smaller diameter D2 at the inboard end thereof, said inboard end slots being cut into the tube only at the portion having a diameter D1.
Claim 10
Dependent Claim
53 words
The sub-assembly as set forth in Claim 4 characterized by the torque tube having a radially extending portion at the outboard end and the outboard end slots are cut through the extension, said radial extension of the tube and radial extensions of the keys providing a continuous radially extending backup for the backplate.
