变速箱会出现的故障以及解决方法又有哪些?

发布日期: 2021-12-28 来源: http://www.jnbsx.com/ 点击:

自动挡汽车可以说是广大女性车主的青睐,由于自动变速箱可以自动根据发动机的转速完成换挡,驾驶技术不好的女性司机也完全可以驾驭自动挡。不过很多车主们对于车辆自动变速箱的保养维护知识却知之甚少,开车过程中不注意维护保养,变速箱很容易发生故障。自动变速箱一旦出现问题维修起来也是非常麻烦,小编总结了变速箱的几个很容易出现的故障,个个都是很棘手的问题!

Automatic cars can be said to be favored by the majority of female car owners. Because the automatic transmission can automatically shift according to the speed of the engine, female drivers with poor driving skills can also control automatic gears. However, many car owners know little about the maintenance of the vehicle's automatic transmission. If they don't pay attention to maintenance during driving, the transmission is prone to failure. Once there is a problem with the automatic transmission, the maintenance is also very troublesome. Xiaobian summarized several easy faults of the transmission, all of which are very difficult problems!
1、起步或行驶有冲击
1. Impact when starting or driving
故障情况:在起步时或行驶中、加速时汽车有明显的冲击感。
Fault condition: the car has obvious impact feeling when starting, driving and accelerating.
造成这样故障的原因可能是:发动机怠速过高;节气门拉索或节气门位置传感器调整不当,使主油路油压过高;主油路调压阀有故障,使主油路油压过高;换挡执行元件打滑;油压电磁阀不工作;电脑有故障。
The causes of such faults may be: the engine idle speed is too high; Improper adjustment of throttle cable or throttle position sensor causes high oil pressure in the main oil circuit; The pressure regulating valve of the main oil circuit is faulty, which makes the oil pressure of the main oil circuit too high; Shift actuator slipping; The oil pressure solenoid valve does not work; There is something wrong with the computer.
2、入档迟、入档死、入档冲击
2. Late shift in, dead shift in and impact of shift in
故障情况: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。
Fault condition: the test entry standard is to start the engine, idle, step on the brake and enter the gear. The normal situation is to feel like entering the gear within 1-1.2 seconds and release the brake pedal. Without stepping on the accelerator pedal, the vehicle will start slowly and gradually extract the speed of 10-20 km / h. This is the normal entry standard, If the gear in delay is located more than 2 seconds after gear in, this situation 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,但这个冲击比较大是不能够接受的,而引发的这个问题的原因就很复杂而且包括除了变速箱以外的很多方面。
If there is a strong impact feeling when shifting in, that is, the impact of positioning into gear, it should be noted that any automatic transmission has a certain degree of impact feeling when shifting in. If there is no feeling at all, it indicates that there is an internal fault, but the impact is relatively large, which is unacceptable, The causes of this problem are very complex, and include many aspects except the gearbox.
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,引发这个问题有变速箱的问题也有其他车身系统的问题。
The situation of stalling is that the engine will stall when shifting in. This problem is more obvious when the car is cold. This problem is caused by the gearbox and other body systems.
3、引擎空转
3. Engine idling
引擎空转一般发生在两种情况:
Engine idling generally occurs in two situations:
一是在车辆在平稳种突然出现引擎空转的现象,在车速慢下来又恢复正常,这种情况一般说明变速箱在短的时间内突然从高的档位降为低档位,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。
First, the engine idling occurs suddenly when the vehicle is stable and returns to normal when the vehicle speed slows down. This generally indicates that the gearbox suddenly drops from high gear to low gear in a short time. The problem may lie in the control system or heat dissipation system, and the gearbox itself has no problem.
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变速箱内的离合器等相关环节上,处理起来要对变速箱进行解体检修,时间成本消耗都要比前者多出许多。
Second, there is a short slip and idling phenomenon in the process of acceleration or gear shifting. The intuitive feeling is that the latter is not as powerful as the former. In fact, it is exactly the opposite. Most of the problems of the latter lie in the clutch and other related links in the gearbox. It is necessary to disassemble and repair the gearbox, and the time and cost consumption are much more than the former.
6行驶中引擎转速高
6 high engine speed during driving
这个问题也包括平稳行驶中一直转速高和提速过程中转速两种情况:
This problem also includes two situations: high speed during smooth driving and high speed during acceleration:
一、平稳过程中转速高,这种情况比较容易测试,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,则说明有故障,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。
1、 The rotating speed is high during the stationary process, which is easy to test. For example, a vehicle with an engine displacement of 2.0 can reach 100 km at 2600 rpm. If it often needs 3000 rpm or more to reach 100 km for a period of time, it indicates that there is a fault. Generally, this fault is caused by the failure of the high-speed gear of the transmission or the failure of the lock up clutch inside the knob, The transmission needs to be serviced immediately.
二、提速过程中转速高,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水准方可完成。
2、 The speed is high during the acceleration process. This fault test is a little complicated, because during the acceleration process, the increase of engine speed is closely related to the accelerator pedal. For example, a normal Passat can accelerate the vehicle when the engine body speed is 2500 RPM under the condition of small throttle, but the engine will increase to 5500-6000 RPM under the condition of full throttle, Such a huge contrast is due to the fuzzy logic control of the electronic control system of the gearbox, so this standard needs a certain level to be completed.
相应的解决方法:
Corresponding solutions:
1、检查自动变速器油油面高度。若太高或太低,应调整至正确高度。
1. Check the automatic transmission oil level. If it is too high or too low, adjust it to the correct height.
2、应举升器将汽车升起,起动发动机,在空档、前进档、倒档等状态下检查自动变速器产生异响的部位和时刻。
2. Lift the vehicle with the lifter, start the engine, and check the position and time of abnormal noise produced by the automatic transmission under the conditions of neutral, forward, reverse, etc.
3、若在任何档位下自动变速器前部始终有连续的异响,通常为油泵或液力变矩器异响,对此,应拆检自动变速器,检查油泵有无磨损、液力变矩器内有无大量摩擦粉末。如有异常,应更换油泵或液力变矩器。
3. If there is a continuous abnormal sound at the front of the automatic transmission in any gear, usually the abnormal sound of the oil pump or hydraulic torque converter, disassemble and inspect the automatic transmission to check whether the oil pump is worn and whether there is a large amount of friction powder in the hydraulic torque converter. In case of abnormality, replace the oil pump or hydraulic torque converter.
4、若自动变速器只有在行驶中才有异响,空档时无异响,则为行星齿轮机构异响。对此,应自动变速器,检查行星齿轮机构各个零件有无磨损痕迹、齿轮有无断裂,单向超越离合器有无磨损、卡滞,轴承或止推垫片有无损坏。如有异常,应予以更换。
4. If the automatic transmission makes abnormal noise only during driving and there is no abnormal noise in neutral, it is the abnormal noise of planetary gear mechanism. In this regard, the automatic transmission shall be used to check whether all parts of the planetary gear mechanism have wear marks, whether the gear is broken, whether the one-way overrunning clutch is worn or stuck, and whether the bearing or thrust gasket is damaged. If there is any abnormality, replace it.
