常有车主反映,车辆在升挡、降挡过程中有冲击、顿挫感,或是在加速时出现卡顿怂车的感觉。这就是我们常说的变速箱顿挫。这是自动挡汽车行驶到一定里程常出现的现象。下面
山东变速箱维修人员为您讲解下这个方面。
The car owners often report that the car has a feeling of shock and frustration during upshifting and downshifting, or a feeling of being stuck when accelerating. This is what we often say about the gearbox. This is a common phenomenon when an automatic transmission vehicle runs to a certain mileage. Next, Shandong transmission maintenance personnel will explain this aspect to you.
1、顿挫原因分析
1. Analysis of the causes of setbacks
出现顿挫的原因主要有二,一是电磁阀异常,导致电磁阀异常的原因较多,可能变速箱油变质,导致阀体部件磨损而产生杂质致使电磁阀无法正常调节油压;也可能是本身设备的故障率导致自然损伤。二是阀体阀道损伤,这个阶段的情况就较为严重了,变速箱内部进一步磨损产生的顽固杂质,将使阀道阀芯卡渍,同时产生磨损,故障更加严重。
There are two main reasons for the setback. First, the solenoid valve is abnormal. There are many reasons that cause the solenoid valve to be abnormal. It may be that the gearbox oil is deteriorated, causing the valve body parts to wear and produce impurities, which makes the solenoid valve unable to regulate the oil pressure normally; It may also be the failure rate of the equipment itself that causes natural damage. Second, the valve channel of the valve body is damaged, and the situation at this stage is more serious. The stubborn impurities generated by the further wear inside the gearbox will cause the valve channel and the valve core to be stuck, at the same time, the wear will occur, and the fault will be more serious.
2、是否需要维修
2. Whether maintenance is required
顿挫故障在大部分情况下需要通过维修才能解决。如果是阀体其他地方磨损的杂质干扰到电磁阀部件信号异常,这种情况通过专门的维修有可能恢复电磁阀的正常工作。
The stuttering fault can only be resolved through maintenance in most cases. If the worn impurities in other parts of the valve block interfere with the abnormal signal of the solenoid valve components, the normal operation of the solenoid valve may be restored through special maintenance.
如果因为电磁阀自身的故障率导致自然损伤,则一般需要对电磁阀进行更换。如果阀体内部阀道磨损严重,严重影响变速箱油压正常控制,顿挫现象更加严重,这种情况一般会选择更换阀体。
If the failure rate of the solenoid valve itself causes natural damage, it is generally necessary to replace the solenoid valve. If the valve channel inside the valve body is seriously worn, which seriously affects the normal control of transmission oil pressure, and the bumping is even more serious, the valve body will generally be replaced.
顿挫故障在初期,如果对电磁阀采用清洗或调节等维修手法就能解决问题,在费用上基本以人工费为主。如果需要更换电磁阀,一般只需几百元。如果因为顿挫过于严重,需要更换阀体,其价格一般需要两三千元或以上,具体价格以各品牌实时报价为准。相关内容就来我们网站

In the early stage of the setback, if the solenoid valve is cleaned or adjusted, the problem can be solved. The cost is mainly labor cost. If the solenoid valve needs to be replaced, it usually costs only a few hundred yuan. If the valve body needs to be replaced due to too serious setback, the price will generally cost two or three thousand yuan or more, and the specific price shall be subject to the real-time quotation of each brand.
