摘要
针对汽车驱动桥总成生产中在线检测手段落后的现状,研制了QZS45型汽车驱动桥总成在线测试系统。该系统选用了隔离的静音检测室,采用计算机控制、变频调速电动机驱动;系统中的转矩转速、温度、噪声等测量信号通过板卡与计算机连接,通过编制控制软件,保证了在线检测工作的顺利进行,并实现了自动采样、自动判断、自动汇总的功能,满足了汽车驱动桥总成在线检测的各项要求。
In view of current backward situation in performance test on the assembling process of automotive drive axle,this paper introduced QZS45 automotive drive axle performance on-line test system.The system adopted the soundless-room and transformed variable-frequency motor.The signals of torque,speed,temperature and noise were linked to the computer by means of sensors.The system achieved in testing the brake and fatigue performance based on computer control and design of hardware and software.The system has functions of automatic-collecting,automatic-judging and gathering together and can satisfy all kinds of demand in performance test on process of assembly.
