自动变速箱油底渗漏,导致变速箱油漏光,或者是操纵手柄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,又或者是油泵进油滤网堵塞,油泵损坏等原因,都会导致车辆出现不走车故障。今天小编总结了三个自动变速箱不走车维修实例,供广大车主参考。
The automatic transmission oil bottom leaks, causing the transmission oil to leak out, or the connecting rod or cable between the joystick and the rocker arm of the manual valve is loose, the manual valve remains in the neutral or parking position, or the oil inlet filter screen of the oil pump is blocked, the oil pump is damaged, and other reasons will lead to the non running fault of the vehicle. Today, Xiaobian summarized three examples of non running maintenance of automatic transmission for the reference of car owners.
行驶里程:160214km
Mileage: 160214km
故障现象:不走车,挂R挡时车身会一耸一耸的。
Fault phenomenon: if you don't leave the car, the car body will shrug when you engage r gear.
故障分析:对CVT变速箱的检查,先要检查压力缸是否存在卸压现象,油泵限压阀是否讯在拉伤发卡,后要检查的就是阀体。维修技师对该车做检测时,并未发现存在故障码,一圈测试下来,初步判断该车故障是由于主链轮毂卸压发卡导致的。
Fault analysis: for the inspection of CVT gearbox, first check whether there is pressure relief in the pressure cylinder, whether the pressure limiting valve of the oil pump is strained and stuck, and then check the valve body. When the maintenance technician tested the car, he did not find any fault code. After a round of testing, it was preliminarily judged that the fault of the car was caused by the main chain hub pressure relief and card issuance.
故障维修:拆解后发现,主链轮毂卸压严重,已经卡住,链条拉伤。此车在进京美之前,更换过阀体,维修技师排查发现步进电机阀内部弹簧没有安装。后,更换主副压力缸及链条、阀体后,装复试车,故障排除。
Fault maintenance: after disassembly, it was found that the main chain hub was seriously depressurized and had been stuck, and the chain was strained. Before entering Jingmei, the valve body of this car was replaced, and the maintenance technician found that the internal spring of the stepping motor valve was not installed. After that, replace the main and auxiliary pressure cylinders, chains and valve bodies, and then reassemble them for commissioning and troubleshooting.
行驶里程:186161km
Mileage: 186161km
故障现象:不走车
Symptom: no running
故障分析:该车送至维修厂后,维修技师对其做了检测,发现该车挂档没有任何反应,未显示有任何油压,初步判断应该是油泵轴损坏。
Fault analysis: after the car was sent to the maintenance factory, the maintenance technician tested it and found that there was no response when the car was in gear, and no oil pressure was displayed. It was preliminarily judged that the oil pump shaft was damaged.
故障维修:抬下变速箱后,发现该车的油泵轴断了,导致供油中断,另外,行星架中间轴承也被磨掉了。更换受损件后,清洗其他元件,装复试车,故障排除。
Fault maintenance: after lifting down the gearbox, it was found that the oil pump shaft of the car was broken, resulting in the interruption of oil supply. In addition, the middle bearing of the planet carrier was also worn off. After replacing the damaged parts, clean other components, reassemble and test run, and troubleshoot.
行驶里程:120079km
Mileage: 120079km
故障现象:挂前进挡D挡不走车,挂2挡能正常行驶。
Fault phenomenon: the car does not move when in gear d, and it can drive normally when in gear 2.
故障分析:
济南自动变速箱维修技师对该车做完基本检测后,初步判断为内部摩擦片烧毁,主油压电磁阀存在损坏。
Fault analysis: after the basic inspection of the vehicle, the maintenance technician of Jinan automatic transmission preliminarily judged that the internal friction plate was burned and the main oil pressure solenoid valve was damaged.
故障维修:拆解变速箱发现该车的前进挡摩擦片与倒档摩擦片烧毁严重,电磁阀损坏,无继续使用价值。更换摩片与阀体后翻新变矩器,清洗各元件,装复试车,故障排除。
Fault maintenance: after disassembling the gearbox, it was found that the forward and reverse friction plates of the vehicle were seriously burned, and the solenoid valve was damaged, which was of no further use value. After replacing the friction plate and valve body, refurbish the torque converter, clean all components, reassemble and test run, and troubleshoot.
That's all for the three examples of automatic transmission maintenance failure. If you don't understand this content, please consult http://www.jnbsx.com Let's go.
