变速箱入档迟、入档死、入档冲击的故障分析

发布日期: 2022-07-19 来源: http://www.jnbsx.com/ 点击:

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。现在来讲讲关于变速箱入档迟、入档死、入档冲击的故障分析吧。
Many car owners know little about the maintenance of the automatic transmission. If they don't pay attention to maintenance during driving, the transmission is prone to failure. Now let's talk about the fault analysis of the late shift, dead shift and shock shift of the transmission.
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 gearing standard is to start the engine, idle, step on the brake, and gear in. The normal situation is to feel gearing in 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 gearing standard. If the gearing is more than 2 seconds after gearing, the gearing delay will be positioned. 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 in gear, that is, the positioning impact, it should be noted that any automatic transmission has a certain degree of impact feeling in gear. If there is no feeling at all, it indicates that there is an internal fault, but the impact is relatively large, which is unacceptable, and 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 in gear is that the engine will stall in gear. This problem is more obvious when the car is cold. This problem is caused by the gearbox and other body systems.

此外车辆跑不起包括没有高速,即无论如何行驶,车辆都不能达到100公里/小时个速段。提速很慢,即油门踩的很重但车辆还是慢慢提速,反应很差、缺乏酣畅的感觉,这种情况又包括引擎提速慢,即发动机的转速上不来和转速上得很快但车速不快这两种情况。
In addition, the vehicle can't afford to run, including no high-speed, that is, no matter how you drive, the vehicle can't reach the speed range of 100 km / h. The acceleration is very slow, that is, the accelerator is pressed heavily, but the vehicle still accelerates slowly, with poor response and lack of sound feeling. This situation also includes the slow acceleration of the engine, that is, the speed of the engine does not come up and the speed of the engine is fast but the speed is not fast.
所以这是个非常复杂的问题,正常的测试标准是车辆起步、适当踩加速踏板,引擎转速平稳提升,车辆加速,一般在2500转左右,车速在25-30公里之间,自动变速箱进入换档,引擎的转速在适当回落后逐步回升。
So this is a very complex problem. The normal test standard is to start the vehicle, step on the accelerator pedal appropriately, the engine speed increases steadily, the vehicle accelerates, generally around 2500 rpm, the speed is between 25-30 km, the automatic transmission enters the first shift, and the engine speed gradually picks up after an appropriate drop.
同时车速明显加快,在车辆40公里时二次换档,变速箱在进入三档后,车速会进一步加快,在60公里的速段上会进入变速箱的高档位,整个过程引擎在升档的过程会适当回落后再次提起,无空转、无打滑现象。
At the same time, the vehicle speed is significantly accelerated. When the vehicle is shifted for a second time at 40 km, the speed of the transmission will further accelerate after entering the third gear, and will enter the high gear of the transmission at the speed range of 60 km. In the whole process, the engine will be lifted again after appropriately falling back in the process of upshifting, without idling and slipping.
济南自动变速箱维修人员认为一般引擎排量位2.0左右排量的车辆平稳行驶的情况下,引擎2500-3000转时车速可以达到100公里的时速,如需要进一步提升车速,引擎转速需要同步增加。如果引擎加油很闷、不顺畅一般说明引擎需要检修,如果引擎加速有力则说明变速箱内部档位不对、离合器烧毁、变钮器出现机械故障等。
Jinan automatic transmission maintenance personnel believe that generally, when the engine displacement is about 2.0, the vehicle speed can reach 100 kilometers per hour when the engine is 2500-3000 rpm. If the speed needs to be further increased, the engine speed needs to be increased synchronously. If the engine is stuffy and does not refuel smoothly, it generally indicates that the engine needs maintenance. If the engine accelerates strongly, it indicates that the internal gear of the gearbox is wrong, the clutch is burned, and the button changer has mechanical failure.
要知道自动变速箱一旦出现问题维修起来也是非常麻烦,所以平常的维护是非常重要的一件事儿。更多相关内容就来我们网站http://www.jnbsx.com咨询吧!
