HIGH ENERGY VENTILATED CONSTRUCTION BRAKE WITH DUAL DRUM

摘要

An improved energy capacity brake employing a drum structure with dual braking surfaces may be utilized in a wide variety of industrial and commercial applications requiring braking action. The drum includes first and second annular drum parts joined together to provide a dual drum feature for use with a coupling component together forming a drum brake assembly. In an alternate embodiment the drum may be cast with a single disc member having two braking surfaces.

主权项

1. An improved drum for a drum brake assembly, comprising:
a first annular drum part having a first base member and a first disc member, said first base member of said first annular drum part extending axially outward in a first direction, said first disc member of said first annular drum part being angularly connected to said first base member of said first annular drum part and extending radially inward from said first base member, said first base member having an annular outer surface, said outer surface of said first base member of said first annular drum part being constructed to receive and engage at least a portion of a friction element thereon from a coupling component; a second annular drum part having a second base member and a second disc member, said second base member of said second annular drum part extending axially outward in a direction opposite that of said first base member of said first annular drum part, said second disc member of said second annular drum part being angularly connected to said second base member of said second annular drum part and extending radially inward from said second base member at an angle; and wherein said first disc member of said first annular drum part and said second disc member of second annular drum part being connected to each other form the improved drum.
