行驶于山区丘岭地带经常上下坡的大中型汽车,由于车辆下坡时连续或频繁使用制动器,造成了制动鼓及摩擦片的快速磨损,情况严重的会发生制动器过热,制动鼓龟裂、制动蹄摩擦片烧蚀、轮胎受热稳定高等现象,导致制动效能下降。这样不仅降低了制动器和轮胎的使用寿命,严重时还影响行车安全。 随着汽车技术的不断进步,现在有 Large and medium-sized cars that travel uphill and downhill in the mountainous hills and valleys often cause brake drums and friction plates to wear out rapidly due to continuous or frequent use of brakes as the vehicle descends. In severe cases, overheating of brakes, cracked brake drums , Brake shoe friction plate ablation, high temperature and stability of the tire, resulting in decreased braking performance. This not only reduces the service life of brakes and tires, but also affects traffic safety in severe cases. With the continuous improvement of automotive technology, there are now
