变速箱机电故障时注意哪些?

发布日期: 2021-07-27 来源: / 点击:

济南自动波维修告诉变速箱机电故障时注意哪些?只需要拆卸下变速箱电脑和电磁阀就可以进行维修,为大家更加详细更快了解这款变速箱大家维修人员总结了一些关于这款变速箱的维修案例。下面开始对变速箱电脑进行拆卸及维修。

What should I pay attention to when Jinan automatic wave maintenance tells the gearbox electromechanical failure? We only need to remove the transmission computer and solenoid valve for maintenance, so that we can learn more about this transmission in detail and faster. Our maintenance personnel have summarized some maintenance cases about this transmission. Now start to disassemble and repair the transmission computer.
取下放油螺丝,放掉变速箱内油液,然后对变速箱油底壳进行拆卸,对损坏点进行检查和维修。
Remove the oil drain screw, drain the oil in the transmission, then disassemble the transmission oil pan, inspect and repair the damaged points.
变速箱油底壳拿下,拿下油底壳时,要注意变速箱内部是否还有残留油液,确定油液放掉后,就可以拆卸电脑和阀体。
Remove the transmission oil pan. When removing the oil pan, pay attention to whether there is residual oil inside the transmission. After the oil is drained, you can remove the computer and valve body.
发现变速箱内因磨损不能及时被滤网过滤掉的粉末性脏污,这也是变速箱机电单元为何会损坏的真 正原因,由于变速箱机电单元对变速箱内部工作环境要求非常高,图中的变速箱由于长期得不到保养导致油的润滑度达不到标准,从而会加快变速箱的磨损,和使用寿命的缩短。
It is found that the powdery dirt in the gearbox can not be filtered out by the filter screen in time due to wear, which is also the real reason why the electromechanical unit of the gearbox is damaged. Because the electromechanical unit of the gearbox has very high requirements for the internal working environment of the gearbox, the lubrication of the oil in the gearbox in the figure can not meet the standard due to long-term lack of maintenance, which will accelerate the wear of the gearbox, And shortening of service life.
拆下变速箱电脑和阀体,由于电磁阀不能正常工作,导致变速箱出现顿挫和锁档现象,经过维修人员检测发现故障,是由压力控制电磁阀3卡滞造成。(在这里提醒大家,变速箱电脑故障,在损坏不严重的情况下,一般是可以修复的)。如果是电磁阀故障,必须要更换新的电磁阀。还有阀体,阀体轻微的油污堵塞是可以通过清洗来修复,而磨损的阀体就不能在修复,只能更换新的阀体才可以解决问题。
The computer and valve body of the transmission were removed. The solenoid valve could not work normally, resulting in the collapse and gear locking of the transmission. The maintenance personnel found that the fault was caused by the sticking of pressure control solenoid valve 3( I would like to remind you that the failure of the transmission computer can generally be repaired if the damage is not serious). If the solenoid valve is faulty, it must be replaced with a new solenoid valve. There is also the valve body. The slight oil blockage of the valve body can be repaired by cleaning, while the worn valve body can not be repaired. The problem can only be solved by replacing the new valve body.
把已经损坏的电磁阀进行更换,故障解除,由此可见变速箱出现故障,及时检查及维修,才不会避免其他内部两件损坏带来的损失。
Replace the damaged solenoid valve and remove the fault. It can be seen that the gearbox has a fault. Check and repair it in time, so as not to avoid the loss caused by the damage of the other two internal parts.
