机车的牵引缓冲装置是机车的重要组成部件,它的主要用途是用来将机车与车辆连接,或是分离车辆,同时也是传递牵引力、冲击力,缓和及衰减列车运动由于牵引力的变化和制动力前后不一致而引起的冲击和振动。因此,具有连接、牵引、缓冲等作用。牵引装置的构造、性能和状态在很大程度上影响着机车运动的平稳性。 The locomotive traction buffer device is an important component of the locomotive. Its main purpose is to connect the locomotive with the vehicle or to separate the vehicle. At the same time, it also transmits the traction force, the impact force, alleviates and attenuates the train movement due to the change of the traction force and the braking force Shock and vibration caused by inconsistencies. Therefore, with the connection, traction, buffer and so on. Traction device structure, performance and status of a large extent affect the smooth locomotive movement.
