为了给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5000/6000/750/9000系列和中国贵州凯星BY系列的非公路液力变速箱测试台。该测试台采用手动伺服变量泵和伺服变量马达作为液力变速箱的驱动动力,用RS-485总线技术构建测控系统硬件线路,并用VB6.0进行测控软件的开发,可实现试验参数的采集、显示、存储、处理和报表的打印等功能。现场试验和应用结果表明,液力变速箱测试台的制造符合设计要求,测试数据满足液力变速箱维修质量评定的要求。%To provide the evaluation basis for the detection and maintenance quality of the hydraulic transmission after maintenance, the off-highway hydraulic transmission test bench suitable for American Allison 5000/ 6000/750/9000 series and Guizhou Province＇s Kaixing BY series was developed. The bench adopted the servo-vari- able pump and servo-variable motor as the driving force of the hydraulic transmission. The RS -485 bus technology was applied to construct the hardware circuit of the measurement and control system which was developed by the VB 6.0. The collection, display, storage and processing of testing parameters as well as report printing could be a- chieved. The field experiment and application show that the production of the bench is in agreement with the design requirement and the testing data meet the needs of evaluating the maintenance quality of the hydraulic transmission.
