Axially displaceable brake disc
First Claim
Patent Images
1. An arrangement to connect a brake disc to a hub to be braked in a non-rotatable and axially displaceable relationship comprising:
- a first plurality of projections disposed on said disc extending toward said hub, each of said first plurality of projections having a first end face aligned parallel to an axis of rotation of said disc and said hub;
a second plurality of projections disposed on said hub extending toward and in a staggered relationship with said first plurality of projections, each of said second plurality of projections having a second end face aligned parallel to said axis of rotation, said first and second end faces being disposed on a common circular arc coaxial with said axis of rotation and disposed between said first and second plurality of projections; and
a preloaded elastic band slightly deviated from said common circular arc disposed between and frictionally engaging only each of said first and second end faces so that a rotational displacement of said disc due to braking torque will lead to an increase in the preloading of said band by each of said first plurality of projections causing a further deviation of said band from said common circular arc toward said hub between each adjacent two of said second plurality of projections.

Abstract
A brake disc is connected to a hub to be braked in a non-rotatable and axially displaceable relationship by an elastic soft steel band disposed between and frictionally engaging arcuate projections of the hub and arcuate projections of the brake disc which are disposed between the projections of the hub. With this arrangement the axial displacement of the disc will not require high forces and will not be impaired by corrosion or high temperatures.
