| 20110278102 | Heavy Duty Brake Drum Wear Indicator - A brake drum is disclosed which is configured for providing an external visual indication of braking surface diameter safe operating limits while installed on a vehicle and includes one or more indentations in its outer surface overlaying the area defined by the interior braking surface where the depth of an indentation is at least co-level with a prescribed safe operating diameter of the braking surface. | 11-17-2011 |
| 20090065313 | Composite Brake Drum with Middle Position Squealer Band - A novel composite brake drum with a shell and a drum liner that includes one or more mid-positioned squealer bands that are roughly in line with the ribs of the brake shoes. This places the most rigid part of the brake drum and the location of greatest heat sink over the most rigid portion of the brake shoes, which is also the position of greatest heat input. The axial cooling fins radiating from the squealer band aid in dissipating the heat from friction generated during the braking cycle. | 03-12-2009 |
| 20090014263 | BRAKE DRUM WITH VENT HOLE AND COOLING SCOOP - One embodiment of a brake drum includes a cylindrical main body portion, a brake drum mounting flange portion, a brake drum transition portion, the brake drum transition portion extending between the cylindrical main body portion and the mounting flange portion, the transition portion having a plurality of vent openings, and one air scoop secured at each of the vent openings, whereby rotation of the brake drum and air scoop induces air movement within a brake drum cavity defined by the main body portion. Each air scoop defines a louver opening which faces the angular direction of drum rotation, an air channel in fluid communication with the louver opening and the brake drum cavity, and a deflection surface located in the air channel. The deflection surface is positioned to re-direct air movement entering the louver opening at an angular direction, to a generally radial and inboard direction | 01-15-2009 |
| 20080308364 | Lightweight brake drum with middle position squealer band - A novel brake drum includes one or more mid-positioned squealer bands that are roughly in line with the ribs of the brake shoes. This places the most rigid part of the brake drum and the location of greatest heat sink over the most rigid portion of the brake shoes, which is also the position of greatest heat input. The axial cooling fins radiating from the squealer band aid in dissipating the heat from friction generated during the braking cycle. | 12-18-2008 |
| 20080210504 | Composite Brake Drum with Cgi Cast Liner and a Method for Manufacturing - A vehicle composite brake drum ( | 09-04-2008 |
