摘　　要：提出了ZL50装载机自动变速电控操纵系统的整体方案.通过分析装载机的工作过程,设计了装载机自动变速的控制策略,针对装载机工况复杂的特点,采用人机配合的多模式控制方式,并且提出了强制降一挡功能和前倒挡直接转换功能的设计思想;按照作业装置是否工作设计了不同的换挡规律.通过台架试验,证明控制系统的控制逻辑正确,使用电控系统可以简化操纵,降低驾驶员的劳动强度.The overall arrangement of automatic shift electronic control system for ZL50 loader is introduced. Control strategy of the loader's automatic shift is designed through an analysis of the loader's working course. Man-machine conversation multi-mode control strategy is adopted to adapt to the complex states of working of the loader, and the functions of DSS and direct reversal are presented. Different shift schedules are designed based on whether the driving pump is working. The exactness of control logic is proved by bench tests, and electronic control system makes the shifting operation simple, reducing the driver's intensity of work.
