摘　　要：基于某矿用车辆自主驾驶对制动系统的需求,首先设计了可实现电控制动和踏板制动并存的制动系统,其次根据电控制动的特性设计了一种电液制动阀,使车辆可根据环境自动启动制动并自适应调节制动力矩。阐述了电液制动阀的工作原理和内部结构,确定了阀的主要参数,仿真优化了阀口结构,电液制动阀样机测试性能良好。电液制动阀的设计不仅可以实现某车辆在煤矿井下自主驾驶,同时也给生产插装式电液制动阀的厂家提供了设计参考。Based on the demand for autonomous driving of a certain mining vehicle for the braking system,a braking system that can achieve both electronic control braking and pedal braking was first designed.Secondly,an electrohydraulic braking valve was designed based on the characteristics of electronic control braking,allowing the vehicle to automatically start braking and adaptively adjust the braking torque according to the environment.The working principle and internal structure of the electrohydraulic brake valve were explained,the main parameters of the valve were determined,and the valve port structure was optimized through simulation.The prototype test performance of the electrohydraulic brake valve was good.The design of an electrohydraulic brake valve not only enables autonomous driving of a certain vehicle in a coal mine,but also provides a design reference for manufacturers producing plug-in electrohydraulic brake valves.
