汽车自动变速箱的故障诊断与检测方式

发布日期: 2022-09-27 来源: http://www.jnbsx.com/ 点击:

汽车自动变速箱一旦有故障,应及时送厂检修,不可带故障运行,以免造成更大的损失。下面济南自动变速箱维修人员就来讲讲汽车自动变速箱的故障诊断与检测方式吧。
Once there is a fault in the automatic transmission, it should be sent to the factory for maintenance in time. It is not allowed to run with the fault to avoid greater loss. Now Jinan automatic transmission maintenance personnel will talk about the fault diagnosis and detection methods of automatic transmission.
1、根据故障现象分析,进行故障现象确认。
1. Confirm the fault phenomenon according to the fault phenomenon analysis.
2、如果是电控自动变速箱,而且故障指示灯亮,首先进行自我诊断读取故障码,排除故障码所代表的故障。
2. If it is an electronically controlled automatic transmission and the fault indicator light is on, first conduct self diagnosis and read the fault code to eliminate the fault represented by the fault code.
3、进行自动变速箱和发动机的常规检查,主要项目有:
3. Carry out routine inspection for automatic transmission and engine. The main items are:
a.检查油面高度和油质。
a. Check the oil level and quality.
b.检查并调整加速踏板拉线和节气门位置传感器。
b. Check and adjust the accelerator pedal cable and throttle position sensor.
c.检查选档手柄连动杆系。
c. Check the gear selector linkage.
d.检查空档起动开关及档位开关。
d. Check the neutral start switch and gear switch.
e.检查发动机怠速。
e. Check the engine idle speed.
f.检查轮胎气压及传动系其他相关部位。
f. Check the tire pressure and other relevant parts of the power train.
4、进行失速试验,检查发动机和自动变速箱内部机械技术状况。
4. Carry out stall test and check the internal mechanical and technical conditions of the engine and automatic transmission.

5、手动换档试验;确定故障是在电控部分还是在自动变速箱内部。
5. Manual shift test; Determine whether the fault is in the electronic control part or in the automatic transmission.
6、进行时滞试验,检查日动变速器的离合器、制动器的磨损情况。
6. Carry out time delay test to check the wear of the clutch and brake of the daily transmission.
7、电子控制系统自我诊断和组件及线路检测。
7. Self diagnosis of electronic control system and detection of components and circuits.
8、油压测试,检查油泵、调压阀、调速器油压和油路压力。
8. Oil pressure test, check the oil pump, pressure regulating valve, governor oil pressure and oil circuit pressure.
9、进行道路试验,检查自动换档点、有无异常噪声、振动、打滑以及发动机的制动作用等。
9. Carry out a road test to check the automatic shift point, whether there is abnormal noise, vibration, slip and the braking effect of the engine.
10、综合各项测试结果,分析和判断故障原因和部位。
10. Analyze and judge the cause and position of the fault based on the test results.
此外要知道自动变速箱发生故障,与发动机、电控系统和自动变速箱有关,因此应确认故障在自动变速箱内部后,方可对其进行拆卸检修。更多注意事项就来我们网站http://www.jnbsx.com咨询吧!
In addition, it should be known that the failure of the automatic transmission is related to the engine, electronic control system and automatic transmission. Therefore, it should be confirmed that the failure is inside the automatic transmission before it can be disassembled for maintenance. More notes on our website http://www.jnbsx.com Consult!
