变速箱故障根源之高温原因

发布日期: 2022-08-25 来源: http://www.jnbsx.com/ 点击:

之所以4s店或专修店搞不定变速箱故障,动不动采取外科手术式的大拆大修,是因为他们并不知道到底是什么引发了变速箱故障,治标不治本,没效果并不稀奇。下面山东变速箱维修人员为您讲解高温之下变速箱故障问题。
The reason why 4S stores or specialized repair shops can't fix the gearbox failure and often take surgical overhaul is that they don't know exactly what caused the gearbox failure. It's not uncommon to treat the symptoms but not the root cause. Next, Shandong gearbox maintenance personnel will explain the gearbox fault under high temperature.
根据自动变速箱修理协会数据称:“在所有自动变速箱故障中有90%以上是高温过热导致的。”汽车启动不久后,自动变速箱油温度会升高。当爬坡、高温环境、持续的超高速行驶,市区内走走停停时,自动变速箱油温度会超出安全温度(80℃)。
According to the automatic transmission repair Association, more than 90% of all automatic transmission failures are caused by high temperature and overheating The temperature of the automatic transmission oil will rise soon after the vehicle is started. When climbing, high-temperature environment, continuous super high-speed driving, and stop and go in the urban area, the oil temperature of automatic transmission will exceed the safe temperature (80 ℃).
高温会破坏自动变速箱油的质量和摩擦特性,加大摩擦与磨损,变速箱噪音随之而来,同时,油泥(杂质或脏污)也会在变速箱内部产生(例如阀体、控制管路),导致变速箱出现顿挫、冲击。
High temperature will damage the quality and friction characteristics of the automatic transmission oil, increase friction and wear, and the noise of the transmission will follow. At the same time, oil sludge (impurities or dirt) will also be generated inside the transmission (such as the valve body and control pipeline), resulting in frustration and impact of the transmission.

如果温度超过120℃,橡胶密封材料会开始变硬老化,密封不严渗漏,比较后导致液压降。如果温度更高,变速箱开始打滑,打滑又会反过来使温度升得更高。(奥迪等车型会报警,进入变速箱保护模式)如不及时解决,变速箱会报废。)
If the temperature exceeds 120 ℃, the rubber sealing material will start to harden and age, and the sealing is not tight and leaks, resulting in hydraulic pressure drop after comparison. If the temperature is higher, the transmission begins to slip, which in turn causes the temperature to rise higher. (Audi and other high-end models will give an alarm and enter the transmission protection mode.) if it is not solved in time, the transmission will be scrapped.)
一个定理:在正常的80℃工作温度下,温度每上升10℃,自动变速箱油的使用寿命会减半。例如,90℃时,自动变速箱油的使用寿命会降到75000公里。在100℃(这个温度很多变速箱都会经常出现)时,使用寿命只有35000公里左右。120℃时,则是15000公里。再升高10摄氏度时,使用寿命只剩下7500公里。超过146或者148℃时,自动变速箱在1500或者2000公里前会烧掉。
A theorem: under the normal operating temperature of 80 ℃, the service life of automatic transmission oil will be halved for every 10 ℃ rise in temperature. For example, at 90 ℃, the service life of automatic transmission oil will be reduced to 75000km. At 100 ℃ (this temperature often occurs in many gearboxes), the service life is only about 35000km. At 120 ℃, it is 15000 km. When the temperature rises by 10 ℃, the service life is only 7500 km. When the temperature exceeds 146 or 148 ℃, the automatic transmission will burn out before 1500 or 2000 km.
