摘要
平稳结合阀在自动变速器换挡过程中可以防止离合器液压缸压力瞬间升高造成的换挡粗暴、摩擦片表面温度上升过快、换挡冲击等一系列不良后果,具有改善换挡品质的重要作用。在分析自动变速器换挡过程中离合器结合理想动态特性曲线的基础上,建立了平稳结合阀的数学模型和AMESim环境下的仿真模型,仿真分析了平稳结合阀的动态工作特性,并通过仿真比较了不同结构参数变化对其充油特性及动态工作特性的影响。仿真分析结果可以为平稳结合阀的设计、改进提供依据,并可用于车辆换档过程的性能匹配和预测。
In the process of automatic transmission shift,combination valve can prevent shifting brutally and surface temperature of friction plate rising too fast as well as shift shock and a series of adverse consequences caused by the clutch hydraulic cylinder pressure transiently increased.It plays an important role in improving shift quality.Based on the analysis of the ideal dynamic characteristics of automatic transmission clutch combination during shifting,established the mathematical model and the AMESim simulation model.The dynamic characteristics of the smooth combination valve are simulated and analyzed,and the influences of various structural parameters on dynamic characteristics are compared by simulation.The simulation results can be used as the basis for smooth combination valve design and improvement,and can be used for matching and forecasting the performance of vehicle shifting process.
