装有液力机械自动变速箱的军用履带车辆提高加速性的方法研究

在介绍液力机械自动变速箱控制系统组成及工作原理的基础上，重点讨论了合理选择起步档、选择合适的自动换档点和闭锁点以及换档过程离合器充放油参数的合理控制等策略的运用对提高车辆加速性能的影响。实车试验结果表明，与不采用以上策略的加速过程相比，车辆加速性能得到了明显的提高。

Research on the Method of Improving the Acceleration Performance of Tracked Vehicle with Hydrodynamic Mechanic Automatic Transmission

An introduction of composition and operational principle of hydrodynamic mechanic auto?matic transmission was given.The paper placed emphasis on the methods of improving the acceleration performance of tracked venicle, which contain the choice of proper start gear, the choice of appropriate shitting timing and lock-up timing, and the right control strategy of oil-charging and releasing parame?ters of clutches in shift process. Proving ground test shows that, compared with the accelerating pro?cess without using the above methods, the acceleration performance of vehicle is significantly im?proved .
