Abstract
A brake drum assembly includes an impeller and stator that help cool the brake drum. The impeller and stator combination are especially suited for low-speed vehicle operations. The impeller includes a plurality of impeller vanes formed about the circumference of the impeller that draw cooling air across the brake drum. The impeller is mounted to an external surface of the brake drum for rotation with the drum about an axis of rotation. The stator is held fixed with respect to the drum and includes a first portion that forms a circular band, which is positioned in an overlapping relationship to the impeller, and a second portion that is transverse to the first portion. The second portion extends radially inwardly toward the axis of rotation to form a vertical face. A plurality of stator vanes are formed within the vertical face that direct the airflow away from the brake drum toward an inboard direction that is generally parallel to the axis of rotation.
