目的研究离合器液压系统在不同油流量条件下的热特性。增加油流量是降低离合器温度的重要途径之一。然而，油流量对离合器温度的影响仍有待探讨。设计方法采用热阻网络模型和集总参数法研究离合器液压系统的热特性。将预测的离合器和油的温度变化与实验数据进行了比较。结果表明，摩擦功率越大，离合器和油的温度越高。然而，离合器和油的温度增长率呈现出不同的趋势：前者逐渐下降，后者不断上升。在一定范围内增加油流量会引起离合器温度的降低和油温的升高；但其变化趋势正在逐渐减弱。当油流量足够大时，对离合器温升的影响不大。本文将知识扩展到离合器液压系统的油流供应。所得结论可为传动系统的油液管理提供理论指导。此外，热阻网络模型对其他液压设备的温度变化预测也是有效的。
PurposeThis paper aims to investigate the thermal characteristics of the clutch hydraulic system under various oil flow conditions. Increasing the oil flow is one of the most important approaches to reduce the clutch temperature. However, the effect of the oil flow on the clutch temperature remains to be explored.Design/methodology/approachThe thermal resistance network model and the lumped parameter method are used to study the thermal characteristics of the clutch hydraulic system. The predicted temperature variations of the clutch and the oil are compared with experimental data.FindingsResults demonstrate that the larger the friction power is, the higher the temperatures of the clutch and the oil are. However, the temperature growth rates of the clutch and oil present different trends: the former decreases gradually and the latter increases constantly. Additionally, increasing the oil flow within a certain range gives rise to the decrease of clutch temperature and the increase of oil temperature; nevertheless, their variation trends are gradually weakening. When the oil flow is large enough, it brings a slight effect on the clutch temperature rise.Originality/valueThis paper extends the knowledge into the oil flow supply of the clutch hydraulic system. The conclusions can provide a theoretical guidance for the oil management of the transmission system. Additionally, the thermal resistance network model is also effective and efficient for other hydraulic equipment to predict the temperature variation.
