矿用工程车辆的制动器设计及虚拟验证

Brake design and virtual verification of mining engineering vehicles

本文设计了一种针对矿用工程车辆的新型湿式液压制动装置,静止时通过活塞挤压摩擦片与制动片实现制动效果,运行时液压油注入抵消弹簧压力使车辆运行。然后针对5t工程车辆,匹配了摩擦副的具体参数,并对处于长时间受压工作状态的活塞进行了有限元分析,分析结果表明,对于5t工程车辆,其强度满足要求。

In this paper,a new type of wet hydraulic brake device for engineering vehicles is designed.The piston squeezes the friction lining and the brake lining to achieve the braking effect when it is stationary.When running,hydraulic oil is injected to off set the spring pressure to make the vehicle run.Then for the 5t construction vehicle,the specifi c parameters of the friction pair are matched and the finite element analysis of the pistons under long-term pressure working conditions has been carried out.The analysis results show that for a 5t construction vehicle,its strength meets the requirements.
