自动变速箱故障诊断分析7种现象

发布日期: 2018-10-23 来源: / 点击:

从事汽车维修多年,对于行业技术有着深厚的浅析能力,那接下来教大家日常自动变速箱故障诊断分析7钟现象。

Engaged in automotive professional maintenance for many years, for the industry has a profound ability to analyze the technology, then called everybody daily automatic transmission fault diagnosis analysis 7 minutes phenomenon.
1、挂档难、顿挫感;
1, hanging files difficult, frustration feeling;
起步或行驶过程中,挂、摘、换挡发涩、费力,好像被什么卡了一下,有耸车、震动、顿挫感,有时凉车易挂挡,热车难挂挡,带有很多不舒适性;原因是变速箱内相关齿轮等部件得不到足够的润滑,且形不成持久的润滑膜,使得部件无法流畅工作。有些变速箱如AMT本身就有类似现象,微微的顿挫,这个是产品本身问题,不严重的话是正常现象。其他的变速箱可以先通过换油尝试解决该症状。
In the process of starting or driving, hanging, picking and shifting are astringent and laborious. It seems to be stuck by something. Sometimes the cool car is easy to shift and the hot car is difficult to shift. It has a lot of discomfort. The reason is that the gears and other parts in the gearbox can not get enough lubrication, and the shape is not durable lubrication film. The parts can not work smoothly. Some gearboxes such as AMT itself have similar phenomena, slight setbacks, this is the product itself, if not serious is normal phenomenon. Other gearboxes can first try to solve this symptom by changing the oil.
2、自动挡闯挡、冲击感;
2, automatic blocking and impact.
起步没动力,低速或中速行驶时车子有明显耸车和顿挫感,同时仪表盘上的转速表针上下浮动;中高速行驶过程中急踩油门踏板的情况下,车子打滑,转速表针急速上升和有明显的冲击感;由P档挂入R档和D档,车子有明显的冲击感、闯档。
Start without power, low or medium speed driving car has a distinct sense of towering and setback, and the tachometer needle on the dashboard floating up and down; in the middle and high speed driving process, when the accelerator pedal, the car slipped, tachometer needle rose rapidly and had a clear sense of impact; from the P gear into R and D gear, the car has a clear sense of impact. To break the file.
原因可能是变速箱内出现杂质,在阀体形成堵塞,导致阀体上下运动不畅,无法顺序实现对油压的调节,导致闯挡、换挡冲击故障。
The reason may be impurities in the gearbox, blockage in the valve body, resulting in the valve body up and down movement is not smooth, can not be sequentially adjusted to the oil pressure, resulting in breaking gear, shift impact fault.

3、变速箱异响、噪音大;
3, gearbox abnormal noise, loud noise;
车子在怠速时或行驶以及高负荷行驶过程中,听到变速器有异响,甚至很大的噪音,在挂换挡时有无节奏、沉闷的响声。造成上述现象的主要原因是变速箱内脏污,轴承、齿轮等部件出现磨损或严重磨损,或齿轮侧面有损坏。
When the car is idling or driving at high load, it hears the abnormal sound of the transmission, even a lot of noise, and there is no rhythm and dull noise when it is shifting gear. The main causes of the above phenomena are the internal fouling of the gearbox, wear or serious wear of bearings, gears and other components, or damage to the side of the gears.
4、变速箱温度过高;
4. The gearbox temperature is too high.
行驶过程中电脑显示报警:变速箱温度过高;或行驶一段后自己感觉变速箱过热,甚至烫手。这应该是变速箱内部经常超负荷运转,无法有效控温造成的。
In the course of driving, the computer display alarm: the temperature of the transmission is too high; or after a period of driving, I feel overheated transmission, or even hot. This should be caused by the overload operation of the gearbox and the failure to control the temperature effectively.
5、车子发生打滑或冲击;
5, car skidding or impact;
如果挂上D档或R档车子不走,或者车子反应很迟缓后冲击,或者发动机转速很高但车速却很慢,就意味着变速箱内部的机械传动部分出了问题。
If a car in D or R doesn't go, or the car reacts slowly and then crashes, or the engine rotates at a high speed but at a slow speed, that means something is wrong with the mechanical transmission inside the gearbox.
6、变速箱体内产生异味;
6, the gear box produces peculiar smell.
变速箱体是靠液压油来工作的,当油温过高时,会产生一些燃烧,这些异味会传出来,这就说明变速箱体内的某些实行部件工作不正常。
The gearbox is operated by hydraulic oil, when the oil temperature is too high, it will produce some combustion, and these odors will come out, which indicates that some of the executive parts in the gearbox are not working properly.
7、引擎空转;
7, engine idling;
引擎空转一般发生在两种情况:
Engine idling usually occurs in two situations:
(1)、在车辆在平稳种突然出现引擎空转的现象,在车速慢下来有恢复正常,这种情况一般说明变速箱在短的时间内突然从高档位降为低档位,问题有可能处在控制系统或者散热系统上,变速箱本身没有问题。
(1) The phenomenon of engine idling suddenly appears in the smooth type of vehicles, and returns to normal when the speed slows down. This generally indicates that the gearbox suddenly drops from high gear to low gear in a short time. The problem may be in the control system or heat dissipation system. The gearbox itself is not a problem.
(2)、在加速的过程中或者在换档的过程中出现短暂的打滑空转现象,直观的感觉是后者没有前者那么利害,实际上确实恰恰相反,后者的问题多半处在变速箱内的离合器等相关环节上,处理起来出要变速箱彻底解体检修,时间成本消耗都要比前者多出许多。
(2) In the process of acceleration or in the process of shifting, there is a short slip idling phenomenon. The intuitive feeling is that the latter is not as severe as the former. In fact, it is exactly the opposite. The latter problem is mostly in the clutch and other related links in the gearbox. It needs to be completely dismantled and repaired. The cost of consumption is much larger than that of the former.
