【摘要】：电传动自卸车作为重要的大载重量运输设备,当其在较高的车速下制动时,传统单独的机械制动已不能满足需要,而电制动作为重要的制动形式在此种工况下发挥重要作用,是车辆安全性运行的重要保证。根据电制动器的结构特点和功能特征,以某自卸车1700V/200A电制动器设计与实现为依托,对电制动器进行电路和软件设计及调试。在电制动器的研究中,按照电动轮车辆电气传动系统的功率级别,选择高可靠性的大功率电力电子器件,设计并实现了一款能够满足研究车辆功率需求的1200V200A制动器系统,该系统也基于32位DSP处理器和CAN总线。搭建电传动系统试验台,通过电制动器实验证明可以实现设计的全部功能,并且其功率已经可以满足研究车辆的电气传动系统中电制动器需要,为实车试验及同类产品设计提供参考。
[Abstract]:As an important heavy load transport equipment, the traditional mechanical brake can not meet the requirement when the electric dump truck is braking at a higher speed. As an important form of braking, electric brake plays an important role in this condition, and it is an important guarantee for the safety of vehicle operation. According to the structural and functional characteristics of the electric brake. Based on the design and realization of an electric brake of 1700V / 200A of a dump truck, the circuit and software of the electric brake are designed and debugged. According to the power level of electric drive system of electric wheeled vehicle, high power electronic devices with high reliability are selected. A 1200V200A brake system is designed and implemented, which can meet the requirements of vehicle power. The system is also based on 32-bit DSP processor and CAN bus. It is proved by the experiment of electric brake that all the functions of the design can be realized, and its power can meet the needs of electric brake in the electric transmission system of the research vehicle, which provides a reference for the actual vehicle test and the design of similar products.
