制动鼓工作能力的破坏取决于自身的工作条件。因为格斯、吉尔和玛斯型中等吨位汽车的制动鼓,是在比较好的条件下工作,所以破坏其工作能力的主要形式是磨损。吉尔和玛斯汽车制动鼓的使用寿命,在硬路面道路上行驶时分别为12—20万公里;而在扬尘条件下,则在10万公里以内。克拉斯型,尤其是别拉斯型大吨位汽车的制动鼓,是在非常困难的条件下工作的,所以其寿命相当短。如果说吉尔、玛斯和格斯型汽车的制动鼓,是因为磨损从汽车上拆卸下来,那么大吨位汽车的制动鼓则是由于热裂纹的产生和扩展造成的损坏而从汽车上
The damage to the brake drum’s ability to work depends on his own working conditions. Because the brake drums for Gus, Jill, and Mas mid-tonnage cars work under better conditions, the main form of disruption of their ability to work is wear and tear. Jill and Mas car brake drum life, when driving on hard pavement roads were 120,000 to 200,000 km; in the dust conditions, then within 100,000 km. Claas type, especially the small-tonnage car brake drum, is working in very difficult conditions, so its life is quite short. If the brake drums of Gilles, Mas and Gus are broken down from the car because of wear, then the brake drums of large tonnage cars are damaged from the car due to the generation and expansion of hot cracks
