济南自动变速箱维修
  漏油 | 自动变速箱壳体或者油底壳处有油渗出,一个原因是由于密封件老化,密封不良引起,另一个原因是制造工艺不良造成壳体有沙眼。
  Oil leakage | there is oil leakage at the shell or oil pan of automatic gearbox. One reason is that the seal is aging and the seal is poor. The other reason is that the shell has sand holes due to poor manufacturing process.
  入档发动机熄火,无反应,冲击 | 测试入档标准是启动引擎,怠速,踩住刹车,入档,正常的的情况是1-1.2秒的时间内有入档的感觉,放开刹车踏板,在不踩油门踏板的情况下车辆会慢慢起步并逐步提取到10-20公里/小时的车速,这是一部正常的入档标准,如果入档后超过2秒钟以上即定位入档延迟,这种情况需要立即检修。
  Gear in engine stalled, no response, impact | test the gear in standard is to start the engine, idle, step on the brake, gear in, the normal situation is that there is a sense of gear in within 1-1.2 seconds, release the brake pedal, without stepping on the accelerator pedal, the vehicle will slowly start and gradually extract the speed of 10-20 km / h, which is a normal gear in standard, if more than 2 seconds after gear in That is to say, the positioning in gear is delayed, which needs to be repaired immediately.
  如果入档有强烈的冲击感觉即定位入档冲击,需要说明的是任何的自动变速箱入档都有一定程度的冲击感觉,如果丝毫的感觉都没有,反而说明内部有故障,但这个冲击比较大则是不能够接受的,引发的这个问题很复杂包括除自动变速箱以外的很多方面。
  If there is a strong sense of impact in gear shifting, i.e. positioning impact, it needs to be explained that any automatic transmission has a certain degree of impact in gear shifting. If there is no sense of impact, it means that there is an internal fault, but the impact is relatively large, which is unacceptable. The problem caused is very complex, including many aspects except automatic transmission.
  入档死火的情况是入档时引擎会死火,这种问题在冷车时比较明显,引发这个问题有自动变速箱的问题也有其他车身系统的问题。
  In case of dead fire in gear, the engine will be dead in gear. This problem is obvious when the car is cold. There are problems with automatic transmission and other body systems that cause this problem.
  挂入D或者R,发动机熄火 | 挂入D或者R,发动机熄火这种故障可能是锁止电磁阀损坏或锁止控制阀发卡造成挂D或者R档,然后松开刹车后,车辆并不动。
  Engage D or R, engine off | engage D or R, engine off this kind of fault may be that the lock solenoid valve is damaged or the lock control valve is jammed to engage D or R gear, and then the vehicle does not move after releasing the brake.
  又或者冷车起动后汽车能行驶一小段路程,但热车状态下汽车不能行驶,这种情况多是由于输入轴或者倒档离合器损坏,或者D/R制动器损坏造成,也可能是自动变速箱漏油严重,严重缺油。
  Or the car can drive for a short distance after cold start, but it can't drive when the car is hot. This situation is mostly caused by the damage of input shaft or reverse clutch, or the damage of D / R brake, or the serious oil leakage and lack of oil in automatic transmission.
  换挡杆和手动阀摇臂之间的连杆或拉索松脱,手动阀保持在空挡或停车挡位置。
  The connecting rod or cable between the shift lever and the rocker arm of the manual valve is loose, and the manual valve is kept in the neutral or parking position.
  滤网堵塞 | 行驶过过程中车辆换档冲击,发冲,也是自动变速箱常见的故障现像,这有可能由于自动变速箱油过脏,导致阀体卡滞而引起,常见于滤网堵塞等。
  The filter screen is blocked | during the driving process, the shift impact and impact of the vehicle are also common faults of the automatic gearbox. This may be caused by the dirty oil of the automatic gearbox, which causes the valve body to be stuck, which is common in the filter screen blocking, etc.
  变速箱打滑 | 汽车在行驶过程中,加油门提速过程有发动机空转的声音,车子速度没有提升,感觉整个车子无力,这种现象多数是由于离合器片有烧损引起。
  Gearbox slipping | during the driving process of the car, there is a sound of engine idling during the acceleration of the fuel valve, the car speed is not improved, I feel the whole car is weak, this phenomenon is mostly caused by the burning of the clutch plate.
  自动变速箱因外部原因造成进水,导致变速箱工作不正常,这个可能是由于水箱串油,或者有水从自动变速箱透气帽处进入。
  The automatic transmission is not working normally due to water inflow caused by external reasons, which may be caused by oil leaking from the water tank or water entering from the vent cap of the automatic transmission.
  异响 | a、是轴承异响,一般轴承的异响同转速关系密切,转速越高越有尖叫声,b、是差速器或者主传动齿轮异响,这种异响一般出现在车速50-70公里比较明显,因为齿轮的啮合面不同,一般在加油的时候响声明显,松开油门响声明显减弱。
  Abnormal noise | A is the abnormal noise of the bearing. Generally, the abnormal noise of the bearing is closely related to the rotating speed. The higher the rotating speed is, the squeal will occur. B is the abnormal noise of the differential or main transmission gear. This kind of abnormal noise is generally obvious at the speed of 50-70km. Because the meshing surfaces of the gears are different, the noise is obvious at the time of oil filling, and the sound of releasing the accelerator is obviously weakened.
  c、是油泵等液压系统异响,这种响声同转速关系密切但同车速没有关系,在转速高时因为油泵吸油受阻从而引起尖叫,需要说明的是自动变速箱这个系统同引擎,底盘等件配合在一起工作,很多声音混在一起,鉴定起来殊非易事。
  C. the hydraulic system such as oil pump makes abnormal noise, which is closely related to the rotating speed but not related to the vehicle speed. When the rotating speed is high, the oil pump suction is blocked, resulting in a scream. It should be noted that the automatic transmission system works together with the engine, chassis and other parts, with a lot of noise mixed together, so it is very difficult to identify.
  箱体内产生异味 | 自动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,这就说明自动变速箱体内的某些执行部件工作不正常。
  Peculiar smell in the gearbox | the automatic gearbox is operated by hydraulic oil. When the oil temperature is too high, some combustion will occur and these peculiar smell will be transmitted, which indicates that some executive parts in the automatic gearbox are not working properly.
  自动换挡时间过长或者过短 | 一般自动变速箱都是有特定的换挡转速和车速,如果发现换挡时间突然过长或者过短,这就意味着变速箱的传动比不成比例了,同时会感觉发动机的转速过高,情况更甚者是变速箱不进行换挡,这都说明变速箱出了问题。
  Automatic shift time is too long or too short | generally, automatic transmission has specific shift speed and vehicle speed. If the shift time is suddenly too long or too short, it means that the transmission ratio of the transmission is out of proportion. At the same time, the engine speed is too high, and even more importantly, the transmission does not shift, which indicates that there is a problem with the transmission.
  行驶中引擎转速高 | 这个问题包括平稳行驶中一直转速高和提速过程中转速两种情况:平稳过程中转速高,比较容易测试,比方一部引擎排量2.0的车辆平时在2600转即可车速达到100公里,如果一段时间经常需要3000转或更多方可以达到100公里,则说明此故障,一般这种故障是由于变速箱高速档失效或者变钮器内部锁止离合器失效引起的,需要立即检修变速箱。
  High engine speed during driving | this problem includes two situations: high engine speed during steady driving and high engine speed during acceleration: high engine speed during steady driving, which is easy to test. For example, a vehicle with engine displacement of 2.0 can reach 100 km at 2600 rpm. If it often needs 3000 rpm or more for a period of time to reach 100 km, it means this fault. Generally, this fault is If the high-speed gear of the transmission fails or the internal locking clutch of the converter fails, it is necessary to repair the transmission immediately.
  提速过程中转速过高,这个故障测试有点复杂,因为在提速过程中,引擎的转速的上升同加速踏板有者密切的关联,比方一部正常的帕撒特在小油门的情况引擎一般体速到2500转即可把车辆加速起来,但在全油门的情况引擎会提升到5500-6000转,如此巨大的反差是由于自动变速箱的电子控制系统的模糊逻辑来控制,所以这个标准需要一定的专业水准方可完成。
  The speed is too high in the process of acceleration. This fault test is a little complicated. Because in the process of acceleration, the increase of engine speed is closely related to the accelerator pedal. For example, a normal Passat engine can speed up the vehicle when its body speed reaches 2500 RPM in the case of small throttle, but the engine will rise to 5500-6000 RPM in the case of full throttle. Such a huge contrast is due to automatic transmission The fuzzy logic of the electronic control system of the box is used to control, so this standard needs a certain professional level to be completed.
  引擎空转 | 引擎空转一般发生在两种情况,其一是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,这种情况一般说明自动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,自动变速箱本身没有问题。
  Engine idling | engine idling generally occurs in two situations. One is that the engine idling suddenly occurs when the vehicle is in a stable state, and it returns to normal when the vehicle slows down. This situation generally indicates that the automatic gearbox suddenly drops from the high gear to the low gear in a short time. The problem may lie in the control system or the heat dissipation system, and the automatic gearbox itself has no problem.
  其二是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厉害,实际上确实恰恰相反,后者的问题多半处在自动变速箱内的离合器等相关环节上,处理起来出要自动变速箱彻底解体检修,时间成本消耗都要比前者多出许多。
  The second is that there is a short slip and idling phenomenon in the process of acceleration or shift. The intuitive feeling is that the latter is not as powerful as the former, but it is actually the opposite. The problem of the latter is mostly in the clutch and other related links in the automatic gearbox. In fact, the automatic gearbox needs to be completely disassembled and overhauled, and the time cost consumption is much more than the former.
  针对新车自动变速箱 | 在一般情况下需要每2年或每行驶4万公里更换一次自动变速箱油(简称ATF),不过也是因车型而定,不同的车型要求不一样,建议4-6万公里更换一次,经常在拥堵工况环境,建议缩短里程保养。
  As for the new automatic gearbox, in general, the automatic gearbox oil (ATF) needs to be changed every 2 years or every 40000 km. However, it is also determined by the vehicle model, and the requirements of different models are different. It is recommended to change the automatic gearbox oil every 40000-60000 km, often in congested conditions, and it is recommended to shorten mileage maintenance.
  针对旧车自动变速箱 | 旧车是指5年之后或曾维修过变速箱,4万公里或每年一次保养,亚洲,美洲等4-6档,2-4万公里或每年一次保养,只要维修过的变速箱强力建议一年保养一次。
  For the automatic transmission of used cars | used cars refer to the gearbox that has been repaired five years later, 40000 km or once a year, 4-6 gears in Asia, America, 20000-40000 km or once a year, as long as the gearbox that has been repaired is strongly recommended to be maintained once a year.
