Description

一种机械式轨道车辆电机驱动摩擦制动装置 [技术领域]
本发明属于轨道车辆制动系统技术领域，具体涉及一种轨道车辆电机驱动摩擦制动装置。
[背景技术]
长期以来，轨道交通车辆制动系统都是空气制动机。相对液压传动，空气制动机的压力低，传力效率差，需要较大的制动缸和各种阀体才能满足制动力要求，因此空气制动机的体积和重量都比较大，不仅结构复杂，控制较难，而且占用很多空间，不利于轨道车辆的轻量化设计，于是慢慢发展起来了液压制动系统。相对空气制动系统，液压制动系统整体体积和重量都有减少，控制也更简单，适合安装空间有限制的城市轨道交通车辆。然而，毕竟还是由介质传递制动力，液压制动系统的管路和闷体仍旧复杂，油液也有泄漏风险，目前只用于城市轨道车辆。
在此背景下，本发明完全改变了动力产生方式以及力的传递方式，提供了一种通过电机产生力，由机械传递力的装置，使得制动系统更加紧凑、体积更小、控制更方便、质量更轻、更适用于底部空间小的轨道车辆。
[发明内容]

在一个优选的实施方式中，所述力矩电机为中空式力矩电机，力矩电机与丝杠同轴连接 并固定，当力矩电机转子正向旋转时，向丝杠输出可调节的转矩，实施制动，当力矩电机转子反向旋转时，实施缓解。
在一个优选的实施方式中，丝杠与螺母为非自锁螺纹连接，螺母将丝杠的旋转运动转换为轴向移动，输出轴向推力。
在一个优选的实施方式中，电磁制动器在失电状态下，电磁制动器吸合，不可自由转动；电磁制动器在通电状态下，丝杠与电磁制动器脱开，可自由转动。
在一个优选的实施方式中，施加制动力后，电磁制动器先断电以锁死丝杠，再使力矩电机停止工作，并保持螺母的推力。
一种轨道车辆电机驱动摩擦制动装置的制动方法，其方法如下：当力矩电机转子正转，产生所需制动力矩，电磁制动器与丝杠通电分离，力矩电机转子带动丝杠旋转，丝杠旋转使螺母平动，产生轴向运动，安装在螺母一端的制动摩擦副产生制动夹紧力，此时若电磁制动器断电，电磁制动器将丝杠锁死，制动力将保持；当力矩电机转子反转，对应螺母反向平动，制动摩擦副缓解。
