Abstract
A drum for a constricting drum brake assembly with at least one annular drum insert with a plurality of annular fins forming a cooling ring for transferring heat from the drum generated during the braking action.
Claims20
An improved drum for a constricting drum brake assembly, comprising:
- (a) a drum disposed for rotary movement constructed to be received and engaged within a coupling component for providing a braking action, the drum having an annular outer and an annular inner surface with an annular ring extending radially outwardly from the inner surface;
- and
- (b) at least one annular drum insert disposed inside the drum on the annular inner surface of the drum, the at least one annular insert having a plurality of annular fins extending radially inwardly towards a center of the drum for transferring heat generated during the braking action.
An improved constricting drum brake assembly, comprising:
- (a) a coupling component with an annular array of friction elements operably disposed therein for radial movement;
- (b) a drum disposed for rotary movement with respect to the coupling component, the drum having an annular outer and an annular inner surface with an annular ring extending radially outwardly from the annular inner surface;
- (c) an inflatable tube disposed within the coupling component operable upon inflation to move the friction elements into contact with the outer surface of the drum;
- and
- (d) at least one annular drum insert disposed inside the drum on the annular inner surface of the drum, the at least one annular insert having a plurality of annular fins extending radially inwardly towards a center of the drum for transferring heat generated during the braking action.
2 more elements
An improved drum for a constricting drum brake assembly, comprising:
- (a) an annular drum disposed for rotary movement with respect to a coupling component, the drum having an annular hub and an annular outer surface disposed radially outwardly of the hub about the outer periphery for receiving a friction element;
- and
- (b) at least one annular drum insert disposed inside the drum on an annular inner surface opposite the annular outer surface of the drum, the at least one annular insert having a plurality of annular fins extending radially inwardly for transferring heat generated during the braking action.
