合成闸瓦在车辆上的运用试验在逐年扩大,现在已有近10000辆主型客车正在运用。虽然现用的合成闸瓦在结构形式方面及合成材料成分方面还需继续改进,这种闸瓦在车辆上的运用试验证明,应用新的摩擦材料比较经济,因为它的高耐磨性和比较稳定的摩擦系数成功地保证了机车车辆的高制动效率。6KB-10型合成闸瓦的运用表明,旅客列车在平道上由160公里/小时速度的制动距离为1400米,较铸铁闸瓦缩短30%。必要时制动距离还能缩短。但是由于合成闸瓦的导热性低,制动时动能转变来的热量主要传给轮箍,因此,提高了轮箍的受热量。如果传到铸铁闸瓦上的部分热量为12～15%,那么,传在合成闸瓦上的就不会高于5%。剩下的热量全部传到轮对上。
The application of synthetic brake shoes in vehicles has been expanding year by year, and nearly 10,000 main passenger cars are now in operation. Although the existing synthetic brake shoes still need to be further improved in terms of the structural form and the composition of the synthetic materials, tests on the use of such brake shoes on vehicles prove that the application of the new friction material is economical because of its high wear resistance and comparison The stable friction coefficient successfully guarantees the high braking efficiency of rolling stock. The use of the 6KB-10 synthetic brake shoe demonstrated that the passenger train had a braking distance of 1,400 meters on a flat road at a speed of 160 km / h, which was 30% shorter than that of a cast iron brake shoe. Braking distances can also be shortened if necessary. However, due to the low thermal conductivity of the brake shoe, the heat transferred from the kinetic energy during braking is mainly transmitted to the wheel rim, thereby increasing the amount of heat received by the wheel rim. If the amount of heat transferred to the cast iron brake shoe is 12% to 15%, then no more than 5% will pass on the brake shoe. The rest of the heat spread to the wheel.
