在对矿用自卸车进行长期技术和性能研究的基础上,提出了矿用自卸车气压制动系统在复杂路况行驶中频繁踩踏制动踏板的情况下,存在高压气体不足的问题,而这也是导致矿用自卸车出现故障导致制动性能不良甚至制动失灵的主要原因。为了解决这个问题,研究设计了气压制动电控辅助供气系统。辅助供气系统通过ECU控制电动机来驱动辅助空压机,提供补充气压。
On the basis of the long-term technology and performance study on mining dump truck, the paper put forward the problem of insufficient pressure of high-pressure gas under the condition that the pneumatic brake system of mine dump truck frequently depresses the brake pedal during the complicated road conditions, Leading to mining truck malfunction leading to poor braking performance or even brake failure of the main reasons. In order to solve this problem, the research and design of air brake electric auxiliary air supply system. Auxiliary air supply system through the ECU to control the motor to drive auxiliary air compressor to provide additional air pressure.
