制动器是工程车辆的关键部件,对车辆运行的安全起着决定性作用。不同功用的制动器,其结构也不相同,介绍一种适用于恶劣环境,特别是可在煤矿井下高瓦斯环境中使用的,具有隔爆性能的湿式安全型中央制动器,对其结构特点、工作原理和制动力矩特性进行分析,为设计同类型制动器提供参考,也为使用和维护这种制动器提供理论依据。 Brakes are the key components of engineering vehicles and play a decisive role in the safety of vehicle operation. Different structure of the brake, the structure is not the same, introduced a suitable for harsh environments, especially in high-gas coal mine environment with explosion-proof wet-type safety central brakes, its structural features, working principle And braking torque characteristics of the same type of brake for the design of reference, but also for the use and maintenance of this brake provides a theoretical basis.
