同时，文章还计算了弹簧机构在主要故障点发生故障情况下的故障分闸速度特性曲线。

And at the same time, the fault tripping speed curves were calculated assuming that some components of the spring operation mechanism were in fault.

笔者首次把弹簧制动、液压松闸闭式多盘湿式制动器应用到国产车辆上，使制动系统更加简单、安全、可靠。

It is the first time for the hydraulic loose-brake and multi-dish wet brake with spring braking to be used in vehicle made in China, making the braking system more simple, safer and reliable.
