轮式车辆制动系统双液动力转换器的动态特性

Dynamic Characteristics of Dual Fluid Power Converters in Brake System on Wheeled Vehicles

全动力液压制动系统与传统制动系统相比具有很多优点。因普通液压油无法替代使钳盘式制动器工作的制动液,设计了既能保持全动力液压制动系统优点,又能降低整机制造成本。采用仿真与试验相结合的方法,对设计研制的双液动力转换器进行动态特性分析,掌握了转换器主要结构参数对制动压力响应特性的影响规律。研究结果表明,双液动力转换器能够满足轮式工程车辆对制动系统的要求。

The full power hydraulic brake system has several advantages over traditional brake actuation systems. Because the hydraulic oil cannot replace the brake fluid in caliper disc brake, a dual fluid power converter, which can both retain the advantages of full-power hydraulic brake system and lower the cost of the whole machine, has been designed. By combined means of simulation and experimentations, the dynamic characteristics of completed converter were analyzed and the laws of the dual fluid power converter parameters affecting the responding characteristics of brake pressure were learnt. The result indicated that the converter could meet the requirements of brake systems on wheeled vehicles.
