车辆变速箱热网络模型及瞬态温度节点计算方法
Thermal network modeling and transient temperature node calculation method of vehicle transmission
摘要
Abstract
When the vehicle works normally,the internal parts of transmission are often damaged due to high temperature caused by shifting and other behaviors,which affects the normal driving of the vehicle.Therefore,it is necessary to study the transient temperature field of the transmission.According to the thermal load characteristics of transmission components,the transient thermal network model of transmission was established by thermal network method in the forms of heat source and thermal resistance.The temperature of each transient node in the transmission was calculated,and the temperature rise of high-heat parts of wet clutch and planetary wheel during the whole process of vehicle starting to driving smoothly was analyzed.The results show that the temperature rise law of wet clutch is related to the gear shift.The temperature rise law of the gear is changed with the change of shift position.Temperature rise of parts in planetary gear is basically the same and changes steadily.关键词
