液力变矩器最常见的故障,一是功率不足,二是温度过高。由液力变矩器的特性曲线图可知,当变矩器的输出转矩即涡轮转矩随着外界阻力变化而变化,外界阻力增大时,变矩器的输出转矩也增大,涡轮转速降低。当输出转矩增大到一定值时,涡轮转速降为零,而此时变矩器的输入转矩仍然不变,也就是说发动机的负荷并未改变。因此,当外界阻力大到一定值后,变矩器的输出转矩(涡轮转矩)达到最大值,而涡轮转速为零,机器行驶速度也为零,而发动机却既不冒黑烟又不降速,
The most common torque converter fault, one power shortage, the second is the temperature is too high. According to the characteristic curve of the torque converter, when the output torque of the torque converter, ie, the turbine torque, changes with the change of the external resistance and the external resistance increases, the output torque of the torque converter also increases. The output torque of the turbine Speed reduced. When the output torque increases to a certain value, the turbine speed drops to zero, while the torque converter input torque is still the same, that is to say the engine load has not changed. Therefore, when the external resistance reaches a certain value, the output torque of the torque converter (turbine torque) reaches a maximum value, and the turbine speed is zero, the speed of the machine is zero, and the engine is neither black nor smoke Slow down,
