Abstract
Abstract A disk brake is disclosed for a rotating element mounted on an axle journaled in an axle housing. The rotating element, e.g. a wheel, windlass or winch drum, is provided with a brake-disk carrier having a plurality of angularly spaced axial projections reaching in the direction of the axle housing. The disk and these projections are provided with grooves and mating lugs enabling axial movement of the disk, the grooves being bridged to prevent distortion. One brake shoe is mounted on the axle housing and confronts the disk surface remote therefrom while the other brakeshoe is shiftably actuatable disposed in a structure offset from the axle housing but secured thereto.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
178 words
In a disk brake for a rotating element journaled on a fixed axle, said element being provided with an annular carrier centered on said axle, a brake disk transverse to said axle coupled with said carrier for entrainment thereby, and brakeshoe means mounted on said axle but offset from the axis of rotation for arresting said brake disk, the improvement wherein said carrier is provided with a plurality of peripherally spaced, axially extending channels confronting the edge of said brake disk, said edge being provided with a plurality of peripherally spaced lugs respectively received in said channels with freedom of limited axial displacement therein, said carrier being further provided with releasable detent means at said channels for normally preventing disengagement of said brake disk from said carrier, and a set of leaf springs on said carrier spanning said channels and bearing radially inwardly upon said lugs; said improvement further including first and second shims removably mounted on coacting surfaces of said lugs and said channels in mutually contacting relationship for positive guidance of said disk on said carrier.
Claim 2
Dependent Claim
178 words

Claim 3
Dependent Claim
22 words
The improvement defined in claim 1 wherein said carrier is provided with a plurality of peripherally spaced crenellations provided with said channels.
Claim 4
Dependent Claim
29 words
The improvement defined in claim 2 wherein said chAnnels are formed by throughgoing slots in said crenellations, said leaf springs being secured to the outer surfaces of said slots.
Claim 5
Dependent Claim

Claim 6
Dependent Claim
26 words
The improvement defined in claim 2 wherein said channels are grooves on the inner surfaces of said crenellations, said leaf springs being received in said grooves.
Claim 7
Dependent Claim
18 words
The improvement defined in claim 5 wherein said crenellations are radially enlarged in the region of said recesses.
