某电控硅油离合器风扇系统在重型汽车上的试验分析

Test and analysis of an electronic controlled silicone oil clutch fan system on heavy duty vehicles

风扇、风扇离合器作为冷却系统的一部分,主要功能是随着发动机冷却液温度的变化,风扇离合器自动调节风扇转速。文章对某牵引车硅油风扇离合器调速特性进行了测试:将发动机转速控制在一定值,应用硅油风扇离合器测试软件手动输入风扇命令转速,测试风扇离合器的最高转速,怠速转速,无级调速转速,并对数据曲线做了分析,综合结果显示此风扇、风扇离合器随着冷却液温度变化的响应能力良好,适用于本牵引车,能保证良好的冷却能力。

The fan and fan clutch are part of the cooling system. The main function is that the fan clutch automatically adjusts the fan speed as the engine coolant temperature changes. This paper tests the speed regulation characteristics of a silicone oil fan clutch in a tractor： the engine speed is controlled at a certain value, the fan speed command is used to manually input the fan command speed, test the maximum speed of the fan clutch, idling speed, stepless speed, And the data curve was analyzed, the results show that the fan, fan clutch with the coolant temperature changes in response to good, suitable for the tractor, to ensure good cooling capacity.
