The prevention measures of brake drum failure should be known

The heat conduction and heat dissipation of automotive brake drum material internal organization and casting external structure are two key issues. Therefore, automobile brake drum manufacturers should be based on the brake drum structure to carry out transformation, and increase the structural strength accordingly. For example, directly change the car brake drum wheel side with the position.
In addition, you can change the way the automobile brake drum and its internal round edge, doing so can do it with the edge with the improvement of the stress, the effect of brake drum flange root stress effectively reduce, especially reduce the stress concentration problems of the region may, some of the possible out, in turn, reduce the brake drum bottom failure defects risk.
Here, the basic principle of the electric enclosure can be used for reference to effectively increase the area of the heat dissipation bars and the heat dissipation surface. Some companies have developed and produced with 12 brake drum external structure of vertical reinforcement, objective about this new type structure can effectively strengthen the brake drum brake the radiating surface area and strength, also can promote it in the process of brake drum operation of air flow capacity, optimize the brake drum overall heat dissipation effect, very suitable for the structure of the casting process effectively.
If considered from the mechanical point of view, the reinforcement of the vertical bar can be considered to design into a spiral or a ring is more reasonable, because it can effectively increase the heat dissipation area of the brake surface, but compared with the ordinary vertical bar, its production process is difficult.
