车辆底盘自动集中润滑系统的控制方法及技术

通过对车辆底盘自动集中润滑控制方法的研究，研制了单片机控制和液压控制相结合的底盘自动集中润滑系统。系统通过设置压力传感器实现主油路的压力控制和油泵工作时间的自动调节，通过配油器实现定量储油和将油脂输送至各润滑点，通过电子监控器设定加脂间隔时间，实现自动加脂与故障报警。系统性能检测和样机应用试验表明，该系统能实现底盘油脂润滑的定时定量控制，工作稳定可靠，控制方法合理可行，智能化程度高。

Study on Control Methods and Techniques of Centralized Grease Lubrication Systems for Vehicle Chassis

Based on the research of control methods of the centralized grease lubrication for vehicle chassis, the automatic lubrication system with the combination of single chip microcomputer and hydraulic controls was designed and developed. A pressure transducer was set up in this system to realize pressure control in main lines and adjustment of pump operating time; the distributors were designed to accomplish grease storage in fixed quantity and transport them into all lubricating points; the single chip microcomputer was utilized to control interval lubrication and realize auto-lubricating or fault alarm. The results of the system test and prototype application showed that the grease quantity and lubricating timing for vehicles could be achieved, the lubricating operation was stable and credible, and the control methods were reasonable an dintelligent.
