今年晚期将于伦敦和格拉斯哥区间投入使用的三台试验型先进客运动车组(APT—P),其制动技术当大大迈进一步。作为首次将液力(Hydrokinetic)制动器(见图1)应用到附挂车上的商用动车组APT—P,其制动是在不采用驱动机械吸收功率的情况下,使其每根轴消耗能量的能力比迄今所有别的制动都大得多。同以往所用的任何别的制动器相比,此种液力制动器与液力传动内燃机车的液力变扭器 Three Advanced Advanced Mobile Hydrological Units (APT-P) to be commissioned later this year in London and Glasgow will make a big step forward in braking technology. As the first application of the Hydrokinetic brakes (see Figure 1) to the commercial EMU APT-P on a trailer, the brakes are designed to allow each of its shafts to dissipate energy without using mechanical power absorbed by the drivetrain The ability is far greater than all the other brakes so far. Compared with any other brakes used in the past, such hydraulic brakes and hydraulic torque converter of diesel locomotive
