Abstract

See full text

The present invention discloses a brake drum comprising: a brake drum body, which comprises a mounting portion for connecting a wheel, a braking portion for engagement with a brake shoe, and a transitional connecting portion disposed between the mounting portion and the braking portion; a hoop device is tightly mounted to the outer peripheral surface of the brake portion. The hoop device adopts a plurality of split-type hoop ferrules, or one unibody hollowed-out hoop case. The hoop device tightly mounted to the outer peripheral surface of the brake portion can not only effectively restrain the radial expansion deformation, thereby improving the fatigue resistance of the brake drum body, but also applies a clasp force to the brake drum body, thereby avoiding the danger of burst and flying out of the brake drum body, which greatly improves service life and safety. Moreover, the thickness of the brake portion wall corresponding to the hoop device can be effectively reduced, which not only effectively decreases the temperature difference between the interior and exterior of the brake drum body, but also increases heat conductivity, thereby laying foundation for both heat dissipation and prevention of the happening of the multiple cracks in the inner wall of the brake drum body.
