为研究车辆传动装置部件温度以及流过部件的传动油温度,根据传热学的基本理论,建立了车辆传动装置温度模型,包括传动装置产热模型、部件温度模型和传动油温度模型,将模型进行耦合迭代计算,得到某型车辆传动装置不同工况下传动装置的温度,并将计算结果与试验结果进行了对比。结果表明:在最高车速工况下,传动装置三轴的温度最高,流过前传动的传动油温度最高;在最大负荷工况下,液力变矩器温度最高,综合传动箱前箱体的温度比其他箱体温度高,流过液力变矩器的传动油温度最高。
According to the basic theory of heat transfer, the temperature model of vehicle transmission is established, including the heat generation model of transmission, the temperature model of component and the temperature model of transmission oil. In order to study the temperature of vehicle transmission components and the temperature of transmission oil flowing through components, The coupled iterative calculation was performed to obtain the temperature of the transmission under different operating conditions for a certain type of vehicle transmission. The calculated results were compared with the test results. The results show that the temperature of the transmission shaft is the highest at the highest speed and the temperature of the transmission oil flowing through the front transmission is the highest. Under the maximum load, the temperature of the torque converter is the highest, The temperature is higher than the other cases, and the transmission fluid flowing through the torque converter has the highest temperature.
