自1963年以来,所有新造貨車均装置了ш-1-TM型緩冲器(六边形,第一种,热处理,經改造的)。該緩冲器采用了經压縮处理的螺旋彈簧。改进自动車钩緩冲装置的問題对于增加車辆載重量和列車的吨位以及相应的机車牵引功率均具有重要意义,此外,还直接影响到能否在調車場上提高車辆的許用碰撞速度。从1939年起全部貨車都装备了ш-1-T型螺旋彈簧——摩擦式緩冲装置。ш-1-T型緩冲器在摩擦表面磨合之后其容量为2,700～3,800公斤·米。它能保证总重为84吨的車辆在以6.5公里/小时以下的速度碰撞时的安全,且在这种情况下其纵向力为150吨左右。当緩冲器損坏时,其容量降低到
All new trucks have been fitted with ш-1-TM buffers (hexagons, first, heat treated, modified) since 1963. The buffer uses a compression-treated coil spring. The problem of improving the auto coupler absorber is of great significance for increasing the vehicle load, the tonnage of the train and the corresponding traction power of the locomotive. In addition, it also has a direct impact on the possibility of increasing the allowable collision of vehicles on the yard speed. Since 1939 all trucks have been equipped with ш-1-T-type coil spring - friction buffer device. The capacity of the ш-1-T type bumper is 2,700 to 3,800 kg · m after the friction surface is worn. It guarantees the safety of a 84-tonne vehicle colliding at a speed of less than 6.5 km / h and in this case has a longitudinal force of about 150 tons. When the buffer is damaged, its capacity is reduced to
