液力变速箱测控系统的研制与应用

Research and Application on Measurement and Control System of Hydraulic Transmissions

为维修后的液力变速箱提供检测和维修质量评定依据,研制了适用于美国艾里逊5000/6000/750系列和贵州凯星BY系列的非公路液力变速箱测控系统。该测控系统采用RS485总线技术构建测控系统硬件线路,采用VB6.0进行测控系统的软件开发,实现了对液力变速箱压力、温度、转速及流量等参数的采集、显示、存储、处理和报表打印等功能。现场试验和应用情况表明,该测控系统符合设计要求,测试数据满足液力变速箱性能试验方法规范的要求。

For testing the transmissions after maintenance,the measurement and control system of non-road hydraulic transmissions for the 5000/6000/750 series of Allison transmissions（made in USA） and.the BY series of Kaixing transmissions（ made in Guizhou China ） are researched. In the measurement and control system, the hardware circuit is composed by RS485 bus, the software is developed by V86.0, and the system has the function of data acquisition, data display, data storage, and printing for pressure, temperature, rotational speed and flow of hydraulic transmissions. The testing and application indicate that the measurement and control system and the design and the testing data and to the standard of the hydraulic transmissions performance testing method.
