摘要：

为提高矿用蓄电池电机车的制动性能，对目前普遍采用的单侧基础制动装置和电机反接制动的制动系统进行分析，针对其制动结构及制动理论上的不足，设计了一套由性能可靠、结构合理的脚踏式双侧基础制动机构，提出了一种能够进行能量回收利用的正向回馈制动方案。此系统解决了闸瓦偏磨、能耗制动能源浪费等问题，有效地缩短了制动响应时间，增大了制动力，有效地解决了溜车现象，缩短了制动距离，提高了制动的可靠性；同时，系统还提高了电能的使用效率，延长蓄电池电机车的工作时间，大大提高了经济效益。

Abstract:

A new brake which included a structure reasonable pedal bilateral foundation braking mechanism and a energy recycling positive feedback braking was invented, based on the analysis of the unilateral foundation braking device and the motor reverse braking，to improve the braking performance of mine electric locomotive. This system solves the problems of the eccentric wear of brake-tile and the energy waste of resistance braking, shortens the braking response time effectively, increases the braking force and the braking distance, and improves the braking reliability visibly .In power system operation, in order to reduce energy loss and improve the utilization rate of power supply equipment, the regenerative braking is needed. In practical applications, satisfied results and remarkable economic effects were obtained.
