Material and characteristics of brake drum
发布时间:2022.12.26 新闻来源:澳门新莆京app7748-制动鼓,刹车鼓生产厂家

The brake drum is made of brittle gray cast iron, semi technical asbestos free, semi metallic and other materials, but the most commonly used is semi metallic. Its cost is low. At the same time, the drum brake can increase the braking force by turning the wheels forward, so the absolute braking force is higher. Therefore, it is more used in the rear wheels of small cars. But its wear rate is high, so the overall cost is high. Secondly, its sensitivity is poor, but it is very durable. Drum brake has a good self braking effect. Finally, in high-speed driving, drum brake has poor heat dissipation, which is easy to accumulate heat and cause heat exhaustion of the brake part. The braking force is weakened, but it is not afraid of water.

 

The brake drum has both advantages and disadvantages. The key depends on each person's focus, so I hope these will be helpful to your choice!
