Abstract
A brake drum cooling device for forcing air across the exterior surface of a brake drum when the brake drum rotates, thereby dissipating heat therefrom, includes an elongated band secured in an end-to-end manner externally around a brake drum. The elongated band includes a plurality of air scoops formed unitarily thereon wherein each of the air scoops capture and direct air across the exterior surface of the brake drum when the brake drum is rotated in a forward direction.
Claims20
A device for cooling a brake drum mounted for rotation in a forward direction, said brake drum including a cylindrical wall having an exterior surface, said device comprising:
- an elongated band adapted for being secured in an end-to-end manner externally around said brake drum;
- said elongated band including a plurality of air scoops formed thereon, each of said air scoops capturing and directing air across said exterior surface of said brake drum when said brake drum is rotated in said forward direction;
- and
- wherein each of said air scoops is positioned at an oblique angle to a longitudinal axis of said elongated band.
A device for cooling a brake drum mounted for rotation in a forward direction, said brake drum including a cylindrical wall having an exterior surface, said device comprising:
- an elongated band;
- said elongated band including a plurality of air scoops arranged in spaced relation thereon, each of said air scoops capturing and directing air across said exterior surface of said brake drum when said brake drum is rotated in said forward direction;
- a securement means for securing said elongated band around said exterior surface of said cylindrical wall of said brake drum;
- an elevation means for elevating said elongated band above said exterior surface of said cylindrical wall of said brake drum;
- wherein each of said air scoops comprise an outwardly directed projection having an open leading edge forming an air-intake opening, a closed trailing edge unitary with said elongated band, a closed inner side unitary with said elongated band, and a closed outer side unitary with said elongated band;
- and
- said open leading edge arranged ahead of said closed trailing edge and said closed inner side arranged ahead of said closed outer side when said elongated band is rotated in said forward direction.
A device for cooling a brake drum mounted for rotation in a forward direction, said brake drum including a cylindrical wall having an exterior surface, said device comprising:
- an elongated band;
- said elongated band including a plurality of air scoops arranged in spaced relation thereon, each of said air scoops capturing and directing air across said exterior surface of said brake drum when said brake drum is rotated in said forward direction;
- a securement means for securing said elongated band around said exterior surface of said cylindrical wall of said brake drum;
- an elevation means for elevating said elongated band above said exterior surface of said cylindrical wall of said brake drum;
- wherein said elevation means includes a plurality of inwardly projecting dimples formed in said elongated band, each of said dimples being adapted for abutting said exterior surface of said cylindrical wall and elevating said elongated band above said brake drum when said elongated band is secured around said brake drum.
A device for cooling a brake drum mounted for rotation in a forward direction, said brake drum including a cylindrical wall having an exterior surface, said device comprising:
- an elongated band having a first end and a second end, said elongated band encircling said cylindrical wall of said brake drum;
- and
- a securement means for securing said first end of said elongated band to said second end of said elongated band when said elongated band encircles said cylindrical wall of said brake drum,
- said elongated band including a plurality of air scoops arranged in spaced relation thereon, each of said air scoops capturing and directing air across said exterior surface of said brake drum when said brake drum is rotated in said forward direction,
- said elongated band including a plurality of inwardly projecting dimples, each of said dimples being adapted for abutting said exterior surface of said cylindrical wall and elevating said elongated band above said brake drum when said elongated band is secured around said brake drum,
- whereby said plurality of inwardly projecting dimples permit air flow between said elongated band and said brake drum.
